There is a $0.00 distribution on the invoice that is incomplete or blank.

Delete the blank distribution

Note: Distributions with a 0.00 amount may be ok as long as they have a GL account assigned.

WARNING: Do not delete 0.00 amount distributions if they were a credit amount and changed to 0.00 after it was already paid as it will create a file fix situation. Instead, change that distribution back to the credit amount that was paid then add a new distribution for the opposite amount if that amount needs to be reversed.

1. In Accounts Payable from the Tasks menu, select Change Invoices.
2. Select the Vendor.
3. Select the Invoice.
4. Enter through the invoice information to get to the distribution grid.
5. Go to the distribution line that follows the last completed distribution line. This line can look as if there is nothing on it.
6. If the Delete button is available, this means there is a distribution record on this row. Click the Delete button. If the Delete button is not available, this is not the issue. Refer to article ID 77672 DocLink: Fully paid invoice or Open invoice with distribution showing in Select Invoices to Pay for $0.00 (Include for Pmt still marked on paid invoice or distribution) for another possible solution.
7. Click Yes to the message confirming you want to delete this distribution.
