Dynamics NAV Fix an incorrect payment processed against a Vendor

First step is to Unapply the invoice and payment from each other.


Select Unapply Entries

Then Unapply – and say yes to unapply
The entries are both open again

Go to the General Journal
Enter in the Date, a Document No., Account Type is Vendor, select your Vendor No. then go to Apply Entries


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



When you select Set Applies-to ID – it will drop in the Document No. and then you select OK

This drops in the amount on the line –

Then you just need to add the balancing account of what was used in the Payment Method


Then you are ready to post
