Calculation schema in supplier invoice

80 Views

Hi

I would like to know how supplier invoice calculate items and tax amount. The reason why I asked is that now, we are developing Badi to calculate tax amount in PO. in this case, we should adapt same calculation schema used in supplier invoice in order to avoid wrong result between PO and supplier invoice. Maybe schema will be ether below.

A : (net amount in item 10 * tax rate) + (net amount in item 20 * tax rate) = Gross amount
B : (net amount in item 10 + net amount in item 20 ) * tax rate = Gross amount

Please let me know!

Best,
Daichi
