`
`General Information on Inventory Sampling
`
`The more materials a company has, the more costly it is to carry out a physical inventory by
`counting all stocks. The time required and cost of a physical inventory are reduced considerably if
`only the stock of individual materials is counted. On the basis of these count results, an
`extrapolation is carried out to arrive at an estimated count result for all units of stock managed in
`the SAP System (stock management units).
`The principle of sample taking used here is also used in quality inspection in the R/3 System, since
`only a particular sample is inspected. The result is then applied to the entire quantity.
`To infer the counts for all stock management units by extrapolating the count results for individual
`units, the following prerequisites must be fulfilled:
`¯ The size of the stock management units included in the physical inventory must be large
`enough.
`¯ The selection of stock management units to be counted must be "representative".
`Statistical procedures are used for carrying out inventory sampling:
`A sample to be counted is randomly selected from the stock management units subject to
`physical inventory. The size of the sample depends on the degree of probability (probable
`degree of confidence) with which the extrapolated value inferred from individual counts is
`expected to be valid for all stock management units included in inventory sampling.
`¯ On the basis of the posted count results, an extrapolation is carried out. The result of the
`extrapolation then applies to all stock management units included in inventory sampling.
`¯ The inventory sampling is considered successful, if there is only a small deviation between the
`extrapolated value and the book value and a high probability that the extrapolation result
`contains only a minor error.
`If an inventory sampling is successful, it is assumed that the estimated deviations from the book
`inventory balances are so small that they can be neglected. As in the case of a conventional
`physical inventory, only the stock of the elements actually counted is adjusted. The stock of the
`remaining stock management units remains unchanged.
`If an inventory sampling is not successful, a complete physical inventory must be carried out for the
`stock management units not counted.
`
`SAP-00007228
`
`

`
`Inventory Sampling in the R/3 System
`
`Inventory sampling can be performed in different ways, depending on the following criteria:
`¯ the area of which the inventory sampling is carried out
`¯ the method of inventory sampling used
`¯ the procedure of extrapolation used
`
`Area of Inventory Sampling
`
`Inventory sampling can be carried out in the areas of Inventory Management and Warehouse
`Management. The steps required to carry out an inventory sampling are the same in both areas.
`The only difference is the selection of the objects included in the physical inventory:
`¯
`In Inventory Management:
`The physical inventory is carried out through selection of the materials by plant, storage
`location, material type, and stock type.
`In Warehouse Management:
`The physical inventory is carried out through selection of the storage bins by warehouse number
`and storage type.
`
`¯
`
`Method of Inventory Sampling
`
`As in the case of conventional physical inventory, two methods of inventory sampling are available
`in Inventory Management and Warehouse Management:
`¯ Periodic inventory sampling
`In periodic inventory sampling, the physical inventory counts are carried out on a certain date.
`During the physical inventory, movements in the warehouse as well as changes to the book
`inventory balances are not allowed.
`¯ Continuous inventory sampling
`Continuous inventory sampling can be carried out over an extended period of time. In this
`case, inventory sampling data is updated from time to time to correspond to the latest book
`inventory balances. Changes to the book inventory balances are thus reflected in the
`calculations performed in inventory sampling.
`In the SAP System, there is no difference between the two methods of inventory sampling, neither
`in the steps used to carry out the inventory sampling nor in the calculations performed by the
`system. However, during periodic inventory sampling, you must ensure that the book values will
`not be changed during the process of inventory sampling.
`
`Procedure of Extrapolation
`
`The extrapolation procedure can be based on various mathematical procedures. The SAP System
`currently uses the procedure of mean-value estimation.
`
`SAP-00007229
`
`

`
`How to Carry Out an Inventory Sampling
`
`The procedure of inventory sampling neither depends on the area for which it is carried out
`(Inventory Management or Warehouse Management) nor on the method used (periodic inventory
`sampling or continuous inventory sampling). The procedure of inventory sampling comprises
`several general steps.
`Before you can carry out an inventory sampling, you must set it up with the Create function. In this
`process, you have to define several basic parameters, such as:
`¯ the currency used for inventory sampling
`¯ the area for which the inventory sampling is carried out (Inventory Management or Warehouse
`Management)
`¯ the deviations up to which an inventory sampling is still considered successful
`When you create an inventory sampling, it is assigned a number that uniquely identifies it. Any
`further steps are carried out as changes to this inventory sampling created.
`The following graphic shows the preparatory phase of inventory sampling.

`
`In the preparatory (or setup) phase, the following steps are required:
`¯ Allocating stock management levels
`You must specify which stock management units are to be included in the inventory sampling.
`You do so by allocating certain quantities of stock management units, the so-called stock
`management levels, to the inventory sampling, rather than assigning individual stock
`management units to the inventory sampling.
`¯ Formation of the stock population
`The stock population is the total of all stock management units of an inventory sampling. When
`forming the stock population, the following actions are carried out automatically:
`Breakdown of the stock population into complete-count area and sampling area
`You can preset that counting of particular stock management units is mandatory; for
`example, if the material exceeds a certain price or if no book inventory balance exists for the
`stock management unit. The total of these elements is called complete-count area. All
`stock management units of the complete-count area must be counted. The stock
`management units that do not necessarily have to be counted form the sampling area.
`
`SAP-00007231
`
`

`
`Classification
`The elements of the sampling area are divided into individual classes. Elements of
`"approximately" the same value belong to the same class. The generation of classes is
`necessary for stratification.
`¯ Generating the stratification
`To reduce the number of stock management units to be counted to a minimum, the sampling
`area is divided into individual strata. The stratification is generated using classification.
`Consequently, the value dispersion in a stratum is considerably smaller than in the entire
`sampling area. With a small value dispersion, only relatively few elements must be selected to
`obtain a representative result. This has the advantage that considerably fewer elements must
`be counted than would be necessary if the random selection was performed for the entire
`sampling area. Therefore, the random selection is carried out separately for each stratum.
`The process of stratification completes the preparatory phase. After stratification, the active phase
`of inventory sampling begins. The following graphic shows the individual steps within the active
`phase.

`

`
`The following steps are required in the active phase:
`¯ Generating the random selection
`In the process of random selection, the system determines the stock management units to be
`counted for each stratum.
`Creating physical inventory documents
`Physical inventory documents must be created for the stock management units to be counted.
`These documents are required both for all stock management units drawn during random
`selection and for all stock management units that were allocated to the complete-count area
`when the stock population was formed. The physical inventory documents are the basis of the
`physical inventory. For detailed information on this subject, see the MM Material Valuation
`Guide.
`Carrying out the update
`During the update process, the system performs the following two actions first:
`It reads any count results.
`It reads any changed book inventory balances and book values.
`In addition, the system determines for each stratum whether the selected elements are
`representative of the particular stratum. If not, you can initiate a subsequent (or secondary)
`random selection. In a subsequent random selection, the system calculates how many
`additional elements must be counted and then randomly selects these elements from the
`elements not yet selected. Also for these elements, physical inventory documents must be
`created.
`¯ Performing the extrapolation
`During the extrapolation process, the system estimates the book inventory balances on the
`basis of the latest counting results. If you have entered only part of the counting results yet,
`you can perform a provisional extrapolation. After all counting results have been entered, the
`final extrapolation is carried out. In the final extrapolation, the system calculates whether the
`inventory sampling is successful, that is, whether any deviations between the book inventory
`balance and actual stock are so small that it can be assumed in all probability that the book
`inventory balances and actual stocks of the uncounted elements agree with each other.
`The procedure of inventory sampling starts with setting up the inventory sampling using the Create
`function. All further processing steps are performed as changes to the inventory sampling created.
`
`SAP-00007233
`
`

`
`Creating an Inventory Sampling
`
`To create an inventory sampling with the R/3 System, proceed as follows:
`
`1. From the Physical Inventory menu, select Inventory sampling ~Create~R/3 System. The
`initial screen is displayed.
`2. On the initial screen, you have to enter the following information:
`¯
`In which area (Inventory Management or Warehouse Management) is this inventory sampling
`carried out?
`¯ Which inventory sampling profile is used for this inventory sampling? The inventory sampling
`profile contains various data: the currency in which the calculations are performed and various
`parameters which the system proposes as default values during inventory sampling. The
`inventory sampling profiles are set via the Customizing system of Inventory
`Management/Physical Inventory.
`3. To go to the parameter screen, press the Parameters button.
`Check the parameters on the parameter screen. The following parameters are of particular
`importance, because you can only change them when creating the inventory sampling:
`Inventory sampling method
`Extrapolation procedure
`Probable degree of confidence
`Relative statistical error
`Relative deviation between book and actual value
`(Currently, the extrapolation procedure parameter cannot be changed because only the
`mean-value estimation procedure is used.)
`The inventory sampling profiles should be set so that changes will not be necessary.
`The remaining parameters can be changed even after creation of the inventory sampling. The
`individual parameters are described in detail in the section dealing with the relevant
`operation/transaction.
`4. Save the inventory sampling.
`The system issues a message confirming that the inventory sampling with number nn has been
`created.
`
`SAP-00007234
`
`

`
`Processing an Inventory Sampling
`
`The procedure of inventory sampling includes the following steps:
`¯ the currency used for inventory sampling
`¯ 1.allocating the stock management levels
`¯ 2.forming the stock population
`¯ 3.generating the stratification
`¯ 4.generating the random selection
`¯ 5.carrying out the update
`¯ 6.performing the extrapolation
`You must perform these steps in this sequence by changing an existing inventory sampling. It is
`also possible to include more than one step in a single change session.
`After having allocated the stock management levels to the inventory sampling, you also have the
`option to complete the subsequent preparatory steps simultaneously, as follows: Use the
`background processing mode to form the stock population and to carry out the stratification and
`random selection in a single step.
`The individual processing steps are explained in detail in the following sections. Each processing
`step is dealt with separately. Therefore, the inventory sampling is saved after each step. If you
`want to include several steps in a change, do not save the data until completion of the last step.

`

`
`Stock Management Units
`
`A stock management unit is part of a material stock that cannot be further subdivided and for which
`a separate book inventory balance exists. The physical inventory is carried out on the basis of the
`stock management units. Each stock management unit of a material will be counted separately,
`and any inventory differences are posted per stock management unit.
`
`Example
`
`Material A exists in plant 0001 with storage locations 0001 and 0002, and in plant 0002 with
`storage location 0007. For this material, there are the following stock management units:

`
`As shown in the above table, the stock of material A consists of 6 stock management units.
`Each physical inventory is carried out on the basis of the stock management units. For this
`purpose, it must be defined which stock management units are included in the physical inventory.
`In inventory sampling, you do not allocate individual stock management units but stock
`management levels.
`
`SAP-00007237
`
`

`
`Stock Management Levels
`
`A stock management level is the total of all stock management units that have the following
`common characteristics:
`¯
`in Inventory Management
`plant
`storage location
`material type
`stock type
`in Warehouse Management
`warehouse number
`storage type
`Various stock management levels are allocated to each inventory sampling. All stock
`management units belonging to these levels will be covered by the inventory sampling, with the
`exception of those stock management units for which a physical inventory has already been active.
`The following example shows a possible allocation of stock management levels to an inventory
`sampling.

`
`In plant 0001, an inventory sampling with this allocation includes the stocks of raw materials in
`storage locations 0001 and 0002 and the semi-finished products in storage location 0001 as well as
`the stock in quality inspection for the raw materials in storage locations 0001 and 0002. In plant
`0002, the stocks of raw materials and semi-finished products in storage location 0003 as well as
`the stock in quality inspection for the semi-finished products in storage location 0004 are also
`included in this inventory sampling.
`
`Presettings
`
`Through the Customizing system of physical inventory, you can define for which stock management
`levels inventory sampling is allowed.
`
`To obtain a list of all possible stock management levels, select Transactions --~Physical inventory
`-~lnventory sampling -~Stock mgmt levels from the Configuration menu of Inventory
`Management/Physical Inventory.
`The stock management levels that are to be selectable for inventory sampling must be selected in
`the column InvSampL allow. (inventory sampling allowed).
`
`SAP-00007238
`
`

`
`Since usually several stock management levels are allocated to an inventory sampling, you can
`group together stock management levels that "belong together". When carrying out the inventory
`sampling, you can then select the stock management levels simply via the group number.
`Belonging to a group does not mean that there are any restrictions for the allocation of stock
`management levels. You can still allocate individual stock management levels from the same
`group as well as stock management levels from different groups to an inventory sampling.
`Generally, the configuration defining which stock management levels can be allocated to an
`inventory sampling, is carried out once before the first inventory sampling. However, later changes
`are possible. For example, if your company sets up new plants, storage locations, or material
`types (IM) or new warehouse numbers and storage types (WM), and you want inventory sampling
`to be allowed for them, you have to change the configuration.
`
`Allocation of Stock Management Levels to an Inventory Sampling
`
`After you have created an inventory sampling, you must allocate the stock management levels to
`this inventory sampling. You can change any allocation defined until you have carried out the
`random selection.
`
`Allocating Stock Management Levels
`
`To allocate the stock management levels to an inventory sampling, proceed as follows:
`
`1. From the Physical Inventory menu, select Inventory sampling -->Change.
`The initial screen is displayed.
`2. Enter the number of the inventory sampling and the year. Then press ENTER. The header
`screen is displayed.
`3. Select Transaction ->Stock mgmt levels ->Selectable.
`You obtain a list of all stock management levels for which inventory sampling is possible.
`4. In this list, select the desired stock management levels. Here, you have the following select
`options:
`¯ Selecting an individual stock management level
`
`Place the cursor on the desired item and select Edit ->Selections ->Select from the menu.
`¯ Selecting a block of stock management levels
`
`Place the cursor on the first item of the desired block and select Edit ->Selections ->Select
`block from the menu. Then place the cursor on the last item of the block and again select
`Edit ->Selections ->Select block from the menu.
`¯ Selecting all stock management levels of a group
`Via the presetting option in the Customizing system, it is possible to combine various stock
`management levels in a group. To select the stock management levels of a group, select
`Edit -> Selections ->Select group from the menu. The system displays a window where you
`enter the desired group number. Then press ENTER.
`5. Use the Copy function to adopt the selected stock management levels.
`The system returns to the header screen where it issues a message confirming that the stock
`managementgmt levels have been adopted.
`6. Save this change you made to the inventory sampling.
`The system returns to the initial screen.
`
`SAP-00007239
`
`

`
`Changing Existing Allocation
`
`Changing an existing allocation is similar to the initial allocation of stock management levels to an
`inventory sampling. However, the system displays additional warning messages and information
`messages. To change the allocation, proceed as follows:
`
`1. From the Physical Inventory menu, select Inventory sampling ~Change.
`The initial screen is displayed.
`2. Enter the number of the inventory sampling and the year. Then press ENTER.
`screen is displayed.
`3. You have two options now:
`¯ You can cancel existing allocations.
`
`The header
`
`To do this, select Transaction -~Stock mgmt levels -~AIIocated from the menu. The system
`displays a list of allocated stock management levels. In this list, deselect the stock
`management levels not required. To adopt all stock management levels that are still
`selected, use the Copy function.
`¯ You can make new allocations.
`
`To do this, select Transaction -~Stock mgmt levels -~Selectable from the menu. The
`system displays a list of all stock management levels that can be selected but are not
`allocated to this inventory sampling. In this list, select the desired lines and use the Copy
`function to adopt them.
`4. Save this change you made to the inventory sampling. The system returns to the initial screen.
`You cannot change the allocation after the random selection has been performed. However, note
`that it may be necessary to adjust the stock population and the stratification accordingly. In this
`case, the system deletes the present stock population and stratification, so that you have to
`regenerate them.

`
`

`
`Stock Population
`
`The stock population is the total of all stock management units included in an inventory sampling.
`These stock management units are uniquely defined through the allocation of the stock
`management levels to a given inventory sampling. As a result, the stock population is also when
`you allocate stock management levels.
`However, the stock management levels do not contain all of the required information on the stock
`management units. Therefore, the stock population must be formed in a separate step after
`allocation of the stock management levels. (The stock population can be changed until you have
`carried out the random selection.)
`When forming the stock population, the system determines whether a physical inventory is currently
`active for each stock management unit of the allocated stock management levels. If inventory is
`being taken for the stock management unit, it will not be included in the stock population. If you
`want a stock management unit for which a physical inventory is currently active to be included in
`the stock population, you must first complete the corresponding physical inventory. That is, you
`either post any inventory differences or delete the physical inventory document. Afterwards, you
`regenerate the stock population.
`The stock population is divided into
`¯
`sampling area
`¯
`complete-count area
`
`SAP-00007242
`
`

`
`Sampling Area and Complete-Count Area
`
`The sampling area is part ofthe stock population. It contains all of the stock management units
`which wil be subject to random selection, a process in which the system selects the stock
`management units (elements) to be counted. For the remaining stock management units of the
`stock population, a complete inventory count is necessary. These stock mangement units thus
`form the complete-count area.
`There are five parameters that determine whether a stock management unit will be assigned to the
`complete-count area:
`¯
`If the deletion indicator is set in the master record for the stock management unit
`¯
`If the book inventory balance of the stock management unit is zero
`¯
`If the stock management unit has an ABC indicator
`¯
`If the price of the material exceeds a certain limit
`¯
`If the value of the stock management unit (material price x quantity) exceeds a certain limit
`You set these criteria before generating the stock population. When generating the stock
`population, the system automatically divides the stock population into the sampling area and
`complete-count area.
`
`SAP-00007243
`
`

`
`Classification
`
`The sampling area of an inventory sampling usually contains a large number of stock management
`units with extremely differing values. The larger the value range between the smallest value and
`the largest value within the sampling area, the more stock management units must be counted, in
`order to obtain statistically correct results.
`To reduce the number of elements to be counted, the system divides the sampling area into
`classes, with each class containing elements of "approximately" the same value. Later, the
`system uses this classification as the basis for generating strata (stratification). For each stratum,
`the random selection and extrapolation is carried out separately.
`Consequently, a class is the quantity of stock management units (in the sampling area) whose
`values lie within a certain interval. These intervals (possibly with the exception of the last one) are
`of equal size, but generally contain a variable number of stock management units.
`The classification of the sampling area is carried out automatically when stock population is formed.
`The parameters set during creation of the inventory sampling are used as the basis for the
`classification. The system attempts to generate 1000 classes. It calculates the class interval on
`the basis of the upper value limit specified, as follows:
`class interval = upper value limit / 1000 (the result is rounded up to the nearest integer).
`On the basis of the class interval, the system then generates classes until the upper value limit is
`reached. Due to the rounding up process, usually less than 1000 classes are generated. The last
`class ends with the upper value limit.
`
`Example
`
`upper value limit:
`class interval:
`
`12430
`
`12430 / 1000 = 12.43--> 13

`
`To
`

`39
`
`11999
`
`12428
`12430
`
`The upper value limit determines that stock management units with a value exceeding this limit are
`allocated to the complete-count area. For this reason, the system generates only 957 classes. If
`the classes just below class 957 contain only few elements, it may be useful to specify a smaller
`upper value limit, in order to obtain a smaller class interval. For example, if classes 924 to 957
`contain only few elements, the upper value limit can be set to 11999. In that case, the elements as
`from class 924 and beyond would then be moved to the complete-count area. This would initially
`increase the number of elements to be counted. However, through a finer classification a more
`favorable stratification may be possible that requires less counting.
`
`SAP-00007244
`
`

`
`Simulation of Upper Price Limits and Upper Value Limits
`
`The division of the stock population also depends on the upper price and value limits which are set
`on the parameter screen. If you change these upper limits, the number of the stock management
`units for which a complete inventory count is required may also change.
`When forming the stock population, you can simulate the number of stock management units to be
`counted for various upper price and value limits. The system then calculates how many elements
`would move to the complete-count area as a result of the changed limits and would therefore have
`to be additionally counted.

`The initial screen is displayed.
`2. Enter the number of the inventory sampling and the year. Then press ENTER.

`3. To go to the parameter screen, use the Parameters button.
`The following fields are important for generating the stock population:
`¯ Consider delete indicator
`¯ Consider zero stock balances
`¯ Consider ABC indicator
`¯ Upper price limit for sampling area
`¯ Upper value limit for sampling area
`If required, you can make changes to the parameters.
`Back button in the standard tool bar.
`Select Transaction ->Stock population from the menu. Since forming the stock population is
`usually a time-consuming process, the system prompts you to specify whether you want to form
`a stock population (or if a stock population has already been formed, overwrite the existing one).
`If you confirm this message by selecting Yes, the stock population will be formed. A window
`appears.
`Inthis window, the following information is displayed:
`Stock population
`The system displays of how many elements the stock population consists.
`Basic population before simulation
`The system determines the maximum price and the maximum value from the elements of the
`stock population. Since none of the elements of the stock population exceeds these
`maximum limits, all elements of the stock population are initially assigned to the sampling
`area.
`Basic population after simulation
`In the fields Upperprice limit and Upper value limit, the system either proposes the upper
`price (or value) limit specified on the parameter screen, or it proposes the maximum price (or
`value) determined, depending on which of these two alternatives is the smaller value. The
`limits shown in these fields result in a new division of the stock population into sampling and
`complete-count areas. You can change the specifications in the Upperprice limit and Upper
`value limit fields and then press ENTER. On the basis of these new values entered, the
`system will re-calculate the division of the stock population into sampling and complete-count
`areas.
`Additional counting
`The data contained in this block of information indicates how many additional elements must
`be counted as a result of the upper price limit and how many as a result of the upper value
`limit. Also, the total number of additional elements to be counted is displayed.

`
`The total number of additional elements to be counted only indicates how many elements
`have moved from the sampling area to the complete-count area due to the new price and
`value limits. The system does not consider that the new upper price and value limits lead to
`a lower value dispersion in the sampling area, so that fewer elements to be counted have to
`be selected from this area. Therefore, the system may indicate here that additional counting
`is required, although the total number of stock management units to be counted is reduced.
`In this window, you can change now the upper price and value limits and start the simulation
`process by pressing ENTER. As a result, the new basic population and the additional number of
`elements to be counted may change.
`After entering the desired upper price and value limits, use the Copy button. Both limits are
`recorded in the parameters.
`The system returns to the header screen with a message confirming that the Stock population
`has been formed.
`In addition, the system will enter the current date and your user ID in the Stock population field
`under Trans/ev (transactions/events).
`7. Save this change you made to the inventory sampling. The system returns to the initial screen.

`Displaying the Stock Population
`
`To display the stock population, select Goto -->List -> Stock population ->Total. The list of the
`stock management units that form the stock population is displayed.
`This list contains all stock management units that are covered by this inventory sampling, according
`to the stock management levels allocated. The stock management units that must be fully counted
`are recorded in the CCA (complete-count area) column. The adjacent columns indicate whether a
`delete indicator (Del), zero stock balance (Zer), or ABC indicator (ABC) exists for the given stock
`management unit. If none of the three columns Del, Zer, or ABC contains an indicator for the
`stock management unit, but the CCA column does, this means that the price and value of the stock
`management unit in question exceeds the upper price and value limits.
`After completion of the random selection (carried out later), the stock management units drawn in
`the random selection process will contain an indicator in the Ran column. After completion of the
`update, the Cnt (counted) and Pos (posted) columns will contain an indicator for those stock
`management units for which the count results have been en
