endating a payment method under receipt class
we have many payment methods for which wrong account combinations are defined for cash account need to change it to correct one. the form "Receipt Classes" (ARXSUDRC.fmx) does allow changing the cash account under the "Remittance Banks" form in GL Accounts tab and is greyed out. if we could not correct this then we might have to create a new payment method with correct account combinations and endate the old one.
is there any API to create a new payment method or correct the old incorrect payment method GL accounts?
