Hello Anil,
The payment method , currency ranking order and house bank should be unique. See the below example.
PAYMENT METHOD CURRENCY RANK ORDER HOUSE BANK
C EUR 1 BNP1
C EUR 2 BNP2
C EUR 3 BNP3
The sequence number controls the order in which the payment program
checks the house banks to determine whether payment can be made from a
particular bank.
Its the priority assigned to each house bank which helps Automatic Payement program choose the house bank for payment in case there are more than one bank satisfying the payment program.
If a payment program ends up selecting more than one(say 4) bank for payment, the ranking of the banks helps it select one bank from the list of (say 4) selected banks
