FDC - Receipts involving different UOM between the Purchase Order and Brazilian Invoice (NF)

Content

We have a scenario here in Brazil where the Puchase Order has one line with 100 units (100 unidades in Portuguese). The invoice's XML is uploaded and it comes with the UOM 1 Hundred (1 CENTO in Portuguese).
The UOM conversion interclass for the item it's created.
But when we insert the information in FDC (Fiscal Document Capture) for Brazil and try to validate the Invoice (NF) we got the following error in "Fiscal Document Validation Errors" screen:

 

"The quantity in line number 1 is different from the quantity allocated in the schedule"

 

In other way, the system it's comparing 100 x 1 and it's not considering the UOM conversion.
