Diagnosis
Format &V1& that is designed for this payment medium run has beenreplaced by format &V2& (for payment method &V4&, in company code &V3&)in Customizing. This replacement should not take place until allpayment mediums are created, for which payment runs were started usingthe old Customizing settings.
The reason for this restriction is that the payment run groups thepayments for the payment medium using the format attributes.

System Response
Processing stops.

Procedure
Ensure that the Customizing settings are active when you maintain theparameters, especially that format &V1& is defined (instead of formatV2). once the payment mediums are created, you can start the nextpayment run with new Customizing settings.
