Cannot post payment - no open item found.

Dear Everyone,

can someone help me with this problem.

I am in a very unique situation where the vendor balance FK10N shows an open item. However, when I tried to post the payment using transaction F110, this item did not show up on the list of payment.

So, I tried posting the payment manually using transaction F-53, and the message was: No open item found. Which is ridiculous, since there IS AN OPEN ITEM due in FK10N.

Please tell me what should I do to solve this problem.

Desperately seeking help.

Thank you.
