I found that I forgot to change the month to which to post a set of Sunday contributions. They got posted to Nov instead of Dec. So the Journal Report is off. Do I have to undo ALL of the contributions, or can I somehow undo the Nov contribution listing and create a Dec one?
I'm guessing that you have a version prior to 11.5, as that version will verify the month on the transaction and post it to the correct month.
That said, you don't have to mess with the Contributions side of the house, you could just reverse the Deposit transaction in Funds Accounting, and manually re-enter the transaction data then post it to the correct month.
