GL posting fails and an error batch is created. Need to find out why the posting failed.
To see what caused errors in error batches:
Run General Ledger -> GL Reports -> GL Posting Journals
In the 'Select Journal' box, select Posting Journal Errors
This report will detail what caused the issue with each posting that generated an error batch. Locate the batch in question and review the note.
Correct the error, then re-post the error batch.
