Since OBCY has selection for AUAK (Settlement Document) and fields Internal Order and Material fields available for summarization, it seemed promising, but I could not test it. I tried adding fields AUFNR and MATNR for AUAK for which I wanted the lines to be summarized. Though the line are anyways getting summarized currently based on totals for debits and credits, Is my understanding correct that once OBCY is updated, the summarization should occur based on the Material number and IO.
Another question is when I tried to save field AUFNR (Internal Order), the system is giving the below error message. We do not have flexible ledger implemented. Can any through some light about this message and how to bypass it?
Field AUFNR is used in the Flexible General Ledger
Message No. GH067
Diagnosis
You want to summarize data using field AUFNR. This is problematic because this field is also used in the Flexible General Ledger. The Flexible General Ledger should where possible be capable of being reconciled (agreeing) with the FI document.
