My new AP personnel accidentally created a AP payment and posted it to the wrong Vendor account.
Now I am stuck with a payment that does not belong there. I tried to reverse it by selecting the transaction in the AP Vendor Transaction window and clicking Reverse transaction button. Then I get a error message "The ledger transaction type Bank for the account XXXX cannot be reversed.
Can someone offer me tips on how to correct this issue.
This is all about Bank module. I believe you have already issued Check. you have to go in Bank module and then to make Payment reversal.
Do as follows
Bank → Common Forms → Checks
Then go to concern check and press Payment reversal. But it needs few set up. Ask your consultant to do that. or if you need to know the set up you can write me.
