Hi Cláudio,
We have a similiar question.
Do you found a solution for this?
In fact we have taxes that will be recovered afterwards (PIS and COFINS) and them are not considered onto total amount of the material in MM, but my client would like to see in FM the exactly ammout that will be paid to the vendor (I know that PSM-FM is not a cash management tool at all but it's the way that client would like to see).
Best Regards,
Ivan F. Spellmeier
