Processing Inventory Differences in the WMS (SAP Library

Processing Inventory Differences in the WMS

Purpose

Entering inventory count results in the Warehouse Management system (WMS) causes differences to occur between the actual counted quantity and the inventory balance for the storage bin or quant. You store the inventory differences in the WMS in order to correct the inventory balance in the warehouse.

If the material has been lost, a negative quant appears in the interim storage area for differences.
If the material has been found, then a positive quant appears in the interim storage area for differences.

You clear these differences from the WMS and enter them in Inventory Management (MM-IM).

Prerequisites

You have performed a physical inventory.

You have set up the interface to Inventory Management (MM-IM).

Process Flow

Entering Inventory Differences

Enter inventory results with a difference between the quantity counted and the inventory balance.

If you make a typing error, you can change the quantity you entered.

If you feel that differences should be investigated, request a recount of the bins.

To determine where differences have occurred, choose Logistics ® Logistics Execution ® Information System ® Warehouse ® Physical Inventory ® With Bin Inventory Management ® Difference Statistics per Storage Type.

Initiating an Inventory Recount

You execute an inventory recount for all items in the system inventory record, for which the differences seem very high.

Choose Logistics ® Logistics Execution ® Internal Whse Processes ® Physical Inventory ® In Warehouse Management ® Count Results ® Recount.

Enter data as required. You can also enter a percentage or monetary value as a deviation threshold on this screen.

Choose Enter.

Select the storage bins for which you want to carry out a recount.

Choose Recount ® Start Recount

The system assigns a version number to the recount and resets the Print complete indicator in the system inventory record.

The system sets the Inv. Status indicator from Z (Counted) to A (Partially counted) in the system inventory record header.

Reprinting the Warehouse Inventory List

Choose Logistics ® Logistics Execution ® Internal Whse Processes ® Physical Inventory ® In Warehouse Management ® Physical Inventory Document ® Print Whse Invent. List.

Enter the following data:

Warehouse number
Inventory record number
Version number of the recount

If you do not enter a version number, the system selects the version number from the most current recount.

Choose Enter.

The system sets the Print complete indicator in the system inventory record.

Recounting Inventory Results

You perform another physical inventory for the selected storage bins.

Entering a Recount

Choose Logistics ® Logistics Execution ® Internal Whse Processes ® Physical Inventory ® In Warehouse Management ® Count Results ® Enter.

Enter the following data:

Warehouse number
Inventory record number
Version number of the recount

If you do not enter a version number, the system selects the version number from the most current recount.

Choose Enter.

Enter the recount results in the Counted Quantity column.

To post the results to the database, choose Inventory count ® Post.

The system sets the Inv. Status indicator from A (Partially counted) to Z (Counted) in the system inventory record.

For more information on entering inventory results, see Entering the Inventory Results in the WMS.

Completing an Inventory with Differences

The system

Creates a transfer order for posting the inventory difference to the interim storage area for differences.
Updates the status in the system inventory record.
Updates the inventory data for the storage bin.
Removes the block on the storage bin.

Clearing Differences

You clear inventory differences from the WMS and report them to Inventory Management. For more information, see Clearing Differences.

Note

If, at this point, not all of the items in the inventory document have been counted, you have to end this function and perform the inventory for the storage bins before continuing.

Entering Differences in IM

Choose Logistics ® Logistics Execution ® Internal Whse Processes ® Physical Inventory ® In Warehouse Management ® Clear Differences ® Inventory Management.

Enter the warehouse number and interim storage type for inventory differences.

In the standard system, storage type 999 is set up as the interim storage area for inventory differences.

Choose Program ® Execute.

The system displays a list of difference items that are planned for clearing to Inventory Management.

Select the bins that you want to clear.
Choose Clear or Save to post the differences from the WMS to Inventory Management (MM-IM).

The system displays a list of all material documents created.

Difference Handling for Inspection Lots from Quality Management (QM)

If you use Quality Management (QM), you manage inspection lots in the warehouse. When posting differences to IM, the system also takes account of stocks with QM lot numbers. The system adjusts the quantity in the inspection lot according to the inventory results.

Note

In contrast to the inventory in Inventory Management, the WMS does not generate a new inspection lot when clearing surpluses, but rather adds the surplus to the original inspection lot.
