  SAP Error Message:
  
  WEBFI_MASTER312 Bank details have been created
  
  Meaning / Cause:
  This message typically appears in the context of SAP Bank Master Data maintenance (FI module, especially in Bank Master or Vendor/Customer Bank Details). It indicates that the bank details you are trying to create or enter already exist in the system. In other words, the bank details record you are attempting to create is a duplicate of an existing record.
  
  The system prevents duplicate bank master records or duplicate bank details for a business partner/vendor/customer.
  This message is informational but can act as a warning to avoid redundant data.
  
  
  When does it occur?
  
  When creating or maintaining bank master data (transaction codes like FI01, FI02, FI12, or during vendor/customer bank details maintenance).
  When entering bank details for a vendor/customer and the same bank details already exist.
  During data upload or interface processing where bank details are created programmatically.
  
  
  Solution / How to resolve:
  
  
  Check Existing Bank Details:
  
  Verify if the bank details you are trying to create already exist.
  Use transaction codes like FI12 (Bank Master), XK03/FD03 (Vendor/Customer display) to check existing bank details.
  
  
  
  Avoid Duplicate Entries:
  
  If the bank details exist, do not create a new record; instead, use the existing one.
  If you need to update details, use change transactions (FI02, XK02, FD02).
  
  
  
  Data Cleansing:
  
  If duplicates exist due to previous inconsistent data entry, consider cleaning up duplicates.
  Use reports or custom programs to identify and merge duplicate bank master records.
  
  
  
  Check for Interface or Upload Issues:
  
  If the error occurs during data upload (e.g., LSMW, BAPIs), ensure the logic checks for existing bank details before creating new ones.
  Modify the upload program to update existing bank details instead of creating duplicates.
