in Brazil, witholding tax has a fixed amount you have to deduce from the calculated amount.
You have an invoice about R$ 1.500, witholding % is 7,5, then you have to deduce 107,59 (fixed amount established by law), so you would have to withold R$ 4,91.
When I create witholding tax codes I only see how to reduce the base amount, not how to reduce the witholding amount.
From R$ 1.434,60 to 2.150 you have to withhold 7,5%, BUT from those 7,5% you have to deduct 107,59 R$ in all cases.
There is no place in SAP I find how to deduct sth from the calculated amount to withhold, the only possibility there is to deduct sth from the base amount.
Thank you very much!
