Hi ANil,
You just have to maintain
In ranking order
PM = C
Crcy = BLANK
Ranking order = 1
Housebank = 100
In bank accounts
House bank = 100
Payment method = C
Currency = BLANK
Account ID BLANK for all or maintain individual
GL account = As required
FBZP will not be used for Payment method determination but would be used for validation. In the sense payment run woudl determine which payment method to use based on Vendor Master, Document and Payment run payment method. Once that is determined it would check if correct config is maintained in FBZP for the Pay method and other combination.
Hope this helps,
Thanks,
S
