in oracle EBS R12, workaround to pay invoices in different currency than invoices ?

in oracle fusion, I am used to change the payment currency on the invoice header level so that i can pay the invoice in different currency. for example if the invoice is in EGP and I want to pay in SAR, i would choose the SAR as payment currency and that's it, now i can pay that invoice in different currency.

In Oracle EBS R12, I am choosing the invoice currency and couldn't select other currency in the payment currency attribute with error (FRM40212: invalid currency for payment currency code). based on that I can't pay in a different currency than the invoice.
