Sending Communication Documents from R/3 to R/2 

Certain transactions result in a data transfer from the R/3 System to the R/2 System. These include:

General Process

For information about general R/3 ® R/2 processes, see R/3 ® R/2 Processes.

Linking Activity Keys to Movement Types

The manner in which activity keys and movement types are assigned to communication numbers in the R/3 System affects how and when transactions that are initiated in the R/3 System are transmitted to the R/2 System.

WM movement types, that initiate communication to the R/2 Inventory Management system, are maintained via the activity key 001 in the R/2 System assignment table (see R/3 ® R/2 Processes). To send data about picked quantities back to the R/2 Shipping system, you must make an entry with the corresponding activity key 002.

To maintain this assignment table, choose Define decentralized link to R/2 in the Interfaces section of the Warehouse Management IMG and then Individual Processing from the list of objects.

Defining Communication Indicators

From the assignment table described above, you can set an indicator that determines whether the communication of data to the R/2 System will take place immediately or depending upon each material.

To set the indicators, position the cursor on the desired line and choose Detail.

The system displays the detail screen for movement type links to the activity key. In the "Assignment" section of the screen, the communication number is displayed along with three fields:

For each of these fields, there are three possibilities for defining communication indicators

"Blank" no communication takes place

"1" A communication record is set up immediately for transmission to R/2.

This indicator is generally used for critical or perishable materials.

"2" material dependent - Another indicator in the material master record (Message to IM) is activated. This second indicator determines whether a communication record is to be set up immediately or whether an accumulated document is to be created by starting a program.

You use indicator "2", for example, for materials that are handled infrequently or materials for which there is generally sufficient stock on hand.

Goods Receipt Posted First in R/3

Goods receipts from production are stored in the R/3 WM system initially without reference to a document posted in R/2. In the assignment table (see above), a corresponding entry (movement type 803) has been created for this purpose. For this example, you want to store 40 pallets from production that are filled with a specified material.

Procedure in R/3

To create the transfer order in the R/3 System
  1. Choose Logistics ® Logistics Execution ® Internal Whse Processes ® Stock Transfer ® Create Transfer Order ® No Source Object from the SAP menu.
  2. As a minimum, you must enter the warehouse number, movement type 803, material quantity, material number, and plant on the first screen. Choose ENTER .
  3. Complete the creation and confirmation of the transfer order.

When you confirm the goods movement, a queue is created in the R/3 System.

How Communication Indicators Affect the Transfer

As described under "Linking Activity Keys to Movement Types" above, the communication indicators affect how and when the transmission of communication documents to the R/2 System take place. The following information applies to the transfer order created for the 40 pallets of material in the example:
