Using R03B50 Automatic AR Cash receipts for multi currency

Hi,

I tried to process AR automated receipts via F03B13Z1 where I have a customer that has foreign currency AR open items. The company is an EUR company and the customer has open AR in USD. Now if I try to do a receipt entering the foreign currency via P03B121 ,  I do not succeed if I use the standard  GL bank account (without currency code in account master). I get an error saying that the  AR payment terms codes not valid... Now I tried again, but by creating a dummy GL bank account with USD as monetary currency in account
