The following table illustrates how movement types in the R/2 Inventory Management (IM) system are connected to movement types in the R/3 WM system.

The first entry in table 341 above is the relevant entry for our example. Here, the following assignments are made:

• WM movement type 101

• Stock category of readily available

• Account assignment to the purchase order number

• Set goods receipt date for quants

• Create transfer requirement in R/3 WM

Activity keys are assigned to communication numbers in table 342.

In table 342 illustrated below, the activity key 001 is used for processing communication documents for goods movements transactions using communication number WMK10, whereas activity key 003 is used to process communication documents for material master records.

In the R/2 System, table 343 is used to define the receiving system.

The module WE_WA_BUCHEN must be identified as illustrated in the above table for the system to address the proper R/3 transaction for posting goods receipts and goods issues.

Using communication numbers, you establish the parameters that are used to define the partner system. With the "Target System" and "Application" parameters, you define the communication at the logical-technical level. The rest of the parameters pertain to the application-specific definition of the communication.

By varying the definitions of the communication numbers, you describe corresponding queues. These queues provide you with the capability to send selected communication documents over separate channels (for example, at separate times).

In column S (start transmission of communication documents), two entries are possible:

For our example, entries in the first line are relevant (see table "Definition of Receiving System" above. The entries "Program SAPML06D" and "Module WE_WA_BUCHEN" cause the receiving routine that is responsible for goods receipts and goods issues to be called up on the R/3 side.
