  Error Message
  WEBFI_MASTER291: The old and new bank details do not relate to the same vendor
  
  Cause
  This error occurs when you attempt to change or update bank details in SAP (typically in vendor master data or payment data) and the system detects that the old bank details you are trying to replace or modify do not belong to the same vendor as the new bank details you are entering.
  In other words, the bank account information you are trying to update or replace is linked to a different vendor than the one currently being processed. This inconsistency triggers the error to prevent incorrect or mismatched bank data assignments.
  Common scenarios causing this error:
  
  Trying to update bank details for Vendor A but referencing bank details that belong to Vendor B.
  Copying or importing bank details from another vendor without proper validation.
  Data entry mistakes where bank account numbers or bank keys are mixed up between vendors.
  Bank details already assigned to a different vendor in the system.
  
  
  Solution
  To resolve this error, follow these steps:
  
  
  Verify Vendor and Bank Details:
  
  Check the vendor master data (transaction XK03 or FK03) for the vendor in question.
  Review the bank details assigned to this vendor (tab: Payment Transactions or Bank Details).
  Confirm that the old bank details you want to replace actually belong to this vendor.
  
  
  
  Check Bank Details Ownership:
  
  Use transaction FI12 (Bank Master Data) or SE16/SE16N on tables like LFBK (Vendor Bank Details) to verify which vendor the bank details belong to.
  Ensure that the bank account number and bank key you are trying to update or replace are not assigned to another vendor.
  
  
  
  Correct the Bank Details:
  
  If the old bank details belong to a different vendor, do not attempt to update them under the current vendor.
  Instead, enter the correct bank details that belong to the current vendor.
  If you need to transfer bank details from one vendor to another, first delete or deactivate the bank details from the original vendor before assigning them to the new vendor.
  
  
  
  Data Consistency Check:
  
  Ensure that no duplicate bank accounts exist across vendors unless explicitly allowed.
  If duplicates are necessary, check your company’s policy and SAP configuration for handling such cases.
  
  
  
  Consult with Finance/Accounts Payable Team:
  
  Sometimes, business rules or vendor master data governance policies restrict bank details sharing.
  Confirm with the responsible team if the bank details should be updated or if a new vendor master record is needed.
