Hi Experts

I have loaded a file with external customer invoices and receveied the following error: Error (Field CURRENCY] is mandatory for Payment Per Currency and requires a value.) occurred while booking Invoice KO 2048525.

in the invoice line information i didnt see any unusual from the other invoices:

Please Note the invoice amount is in total 0 since the line is in Minus and Plus. When i create a manual customer invoice manually i am able to enter minus and plus invoice position and i can post the invoice. Or lets say the invoice goes automatically to paid posted since the amount is 0.

it only seems not to work when i try to upload the invoices.

Does anyone have an idea how to correct the issue?

Best Regards
