3597545 - Incorrect House Bank Used for Payments When Supplier Bank Group is Blank in SAP S/4HANA Cloud Public Edition

When executing the app Manage Automatic Payments, the system does not follow the ranking order for payment. This results in the wrong house bank being used for payments.

"Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental." 

1. Execute automatic payment run through Manage Automatic Payments.
2. Observe the log.
3. Identify that unexpected house bank is utilized for payments.

The issue occurs because the 'Optimize by Bank Group' flag is set in the SSCUI Set Up Payment Methods per Company Code for Payment Transactions. When this flag is set, the payment program will always attempt to select two banks that belong to the same group. 

If the flag Optimize by Bank Group is set:

1. All banks can be divided up into groups for this purpose. You can specify the composition of these groups.
2. When carrying out payment optimization, the payment program will always attempt to select two banks that belong to the same group.
3. In the bank master data, you can determine the bank group to which a bank belongs.

To follow the ranking order, the field 'Optimization by bank group' for the payment method need to be removed. 

1. Navigate to the SSCUI Set Up Payment Methods per Company Code for Payment Transactions.
2. Remove the selection on the flag 'Optimize by Bank Group' flag for the payment method.
3. This will ensure that the system optimizes the payment process as per the ranking order.
