If you receive an Open AP Batches error in project controller closing process, you can find the batches in Accounts Payable. You can print the AP Batch Register report and print the summary format, and look for any batches with a H,B,S, or U status in the list. The screen numbers are listed below so depending on what you find, you can open the batch in the edit screen to release or delete batch. If it unposted, you can go into post transactions in the General Ledger and post it. There is also an Unreleased AP Batches report and review what batches show on that list to adjust. Once the batches in the current year have been addressed, you can try the Project Closing again.
