One of the advantages of an integrated system like SAP is that the system can be configured so that when a goods movement is recorded for production planning or materials management (PP/MM) purposes, the R/3 system will automatically determine the correct G/L account to post to using the type of transaction and other factors. Automatic account determination is also referred to as automatic posting and automatic account determination in the SAP R/3 system.
To configure the SAP system to make the automatic accounting postings, valuation control must be set to active.
For configuration you will see following steps covered;
Create and Assign Valuation Grouping Code to Company Code
Establish Automatic Postings for Inventory Posting (BSX)
Establish Automatic Postings for Offsetting entry for inventory posting (GBB)
Establish Automatic Postings for Cost/Price Difference (PRD)
Establish Automatic Postings for Materials Management Small Differences (DIF)
Establish Automatic Postings for GR/IR Clearing Account (WRX)
Configure price change in previous period/previous year
