There are many transactions in Material Management (MM) that relevant for Accounting. These transactions must be recorded in accounting documents that contain the postings made to the G/L accounts in Financial Accounting (FI). The mostly used MM transactions that relevant for FI can be seen at Accounting Journals of SAP Material Management (MM) Transactions. For those transactions, as far as possible, the SAP R/3 System should determine automatically the G/L account numbers that are involved in the accounting journal. By doing so, we can minimize the inputs and error possibilities made by MM end-users who perform the transactions as they don’t determine the G/L account numbers.
