Hi @TPLaine
Please see below my comment.
Exclude Invoice Lines
If this check box is selected, the invoice lines in the file loaded will be excluded and a single invoice line will be created based on the header amounts when the file is loaded. Note: By default, this check box is not selected.
Recalculate Due Date
If this check box is selected, the invoice due date and installment due dates will be recalculated based on Supplier’s default payment term in Invoice/General tab of the Supplier window. If multiple installments exist in the loaded file invoice due date will be taken to all the installments.
I'm happy to share my advice on this. If you found the answer helpful, please mark it as the correct answer. This will allow us to close the thread and make it easier for other community users to find and benefit from in the future.
