I create a new invoice, with its invoice line. At first, the type of payment term is set to 'immediate'; I change it with one made by me and the mask 'Payment Schedule' correctly calculates the payment schedule.
However, I forgot to activate the process 'Generate withholding tax', so I click, the process calculates the withholding tax. Next, change the type of payment term, but unfortunately I see that the calculation on the mask 'Payment Schedule' always does on Grand Total Amt, not removing the withholding tax.
I've seen that this type of calculation right, does it only when you click on the Process "Action Document," complete the invoice.
Why not do it before this calculation and does so only at the time of completion of the invoice?
Thanks in advance
