For our manual checks we use a two step process:
1. FB01 to create the payment document.
2. FCH5 to create the check that will be associated with the corresponding payment document.
However, we created a check before creating the correct payment document. Now the check corresponds with the incorrect payment document and will be posted to the wrong bank accounts. To make matters worse, the check has been cashed already.
Is there any way to change the posting document associated with this check?
