Enter a General journal
The Document Type needs to be blank; I entered the check number as the document number.  Enter the Customer where it was incorrectly posted to.



Then go to Apply Entries


Select the line – then Actions, Set Applies-to ID


That will drop in the Document No. – select OK



The Amount will drop into the line.
Enter in a second line for the correct customer.

Now you are ready to post
