  SAP Error Message:
  WEBFI_MASTER311
  
  Text: Bank details & (bank no.) & (account no.) cannot be changed in Biller D.
  
  Cause:
  This error occurs when you attempt to change the bank details (bank number and/or account number) for a Biller in the SAP system, but the system does not allow this change because the bank details are already in use or linked to existing transactions or master data that restrict modifications.
  Specifically, in the context of SAP FI-CA (Contract Accounts Receivable and Payable) or SAP IS-U (Industry Solution for Utilities), the Biller master data is tightly controlled. Bank details are critical for payment processing and reconciliation. Changing bank details directly in the Biller master data is restricted to avoid inconsistencies or errors in payment processing.
  
  Typical Scenarios Leading to This Error:
  
  The bank details are already assigned to open or historical billing documents.
  The bank details are linked to payment methods or direct debit mandates.
  The Biller master data is locked or controlled by authorization settings.
  The system configuration or business rules prohibit changing bank details once set.
  
  
  Solution:
  
  
  Check Existing Transactions:
  
  Verify if there are open or historical transactions linked to the bank details. If yes, you cannot change the bank details directly.
  
  
  Create New Bank Details:
  
  Instead of changing existing bank details, create new bank details for the Biller and assign them accordingly.
  
  
  Use Correct Transaction or Process:
  
  Some changes might require specific transactions or processes, such as:
  
  Using the appropriate SAP transaction code for bank master data maintenance.
  Using SAP standard tools or reports to update bank details safely.
  
  
  
  Authorization Check:
  
  Ensure you have the necessary authorizations to change bank details in the Biller master data.
  
  
  Consult Configuration:
  
  Check the configuration in IMG under:
  
  Financial Accounting (New) > Accounts Receivable and Accounts Payable > Business Transactions > Payment Transactions > Bank Determination
  Or under IS-U billing and payment settings.
  
  
  
  Contact SAP Support or Refer to OSS Notes:
