Sage 100

Sage 100 4.5, yep - Not kidding. How do I delete a duplicate AP Batch from the sub ledger? It did not post to the GL. It's a true duplicate. Same batch ID, date, $ amount.

I would suggest that you reverse the batch in AP so it removes all the duplicate entries (AP_Vendor, AP_TransactionHitory, etc). Then just reinit the GL_DailyPosting file (or you could turn off GL Integration prior to reversing the AP batch.) Not sure if that is the best process, but it would for sure have the best audit trail.

Interrupted update, repeated attempts, with multiple copies using different HeaderSeqNo values for the copies? No easy answer. DFDM, file by file, line by line, to remove what you need to remove. Make sure the open invoice file and transaction payment history file is linked properly to the HeaderSeqNo you keep in AP history. Bill for time... the customer will likely want you to fix ""everything"", but if they are paying by the hour, they may not worry about obscure summary tables.

For AR I know which tables - which tables for AP?

I check the file modified date, and look at anything modified after the interrupted batch was run.
