- Open the invoice with the negative distribution, go to the Distribution Tab.
- Change the distribution to only positive amounts. Save and close the invoice.
- Re-open the Invoice and go back to the distribution tab, edit the amounts back to their original amounts.
- Save and close the invoice. Now we should be able to create a payment for the invoice.
If the Invoice has already been posted to the General Ledger, then we would need to do an invoice adjustment
