  The SAP error message:
  WEBFI_MASTER309 Customer & already has bank details with bank no. & and account no. &
  Meaning / Cause:
  This error occurs when you try to add or update bank details for a customer in SAP, but the system finds that the customer already has bank details with the same bank number and account number. Essentially, the bank details you are trying to enter already exist for that customer, and duplicate entries are not allowed.
  This typically happens in the context of managing customer master data, especially in FI (Financial Accounting) or SD (Sales and Distribution) modules where bank details are maintained for payment processing.
  Cause Summary:
  
  Attempt to create or update bank details for a customer.
  The bank number and account number combination already exists for that customer.
  The system prevents duplicate bank details to maintain data integrity.
  
  
  Solution:
  
  
  Check Existing Bank Details:
  
  Go to the customer master data (transaction FD03 for display or FD02 for change).
  Navigate to the bank details tab.
  Verify if the bank number and account number you are trying to enter already exist.
  
  
  
  Avoid Duplicate Entries:
  
  If the bank details already exist, do not re-enter them.
  If you need to update existing bank details, use the change option instead of creating a new entry.
  
  
  
  If You Need to Add Different Bank Details:
  
  Ensure the bank number and account number combination is unique.
  Enter new bank details with a different bank number or account number.
  
  
  
  Data Cleanup:
  
  If duplicate bank details exist due to previous incorrect entries, consider cleaning up the data by deleting or correcting duplicates.
  
  
  
  Check for Integration Issues:
  
  Sometimes, interfaces or batch jobs might try to insert duplicate bank details.
  Review any automated processes or middleware that update customer bank details.
