Example: Set-up for Cumulative Postings 
To configure your system for cumulative transfers for goods receipts and goods issues from R/3 to R/2, steps 1 through 6 above are the same. You set up the tables in the following order:
Movement Type 819
Src 904 TEMP
Dest 904
Movement Type 820
Src 904
Dest 904 TEMP
For movement type 819 (activity key 001), enter 1 in the Source items field (directly to R/2).
For movement type 820 (activity key 001), enter 1 in the Destination items field (directly to R/2).
This movement type is optional and should be used when communication documents are to be transmitted immediately to R/2 based on the material or when the quantities are to be sent cumulatively to the R/2 System.
