  Error Message
  WEBFI_MASTER299:
  
  For partner &1 type &2 the bank details ID &3 is not unique
  
  Cause
  This error occurs when you try to maintain or create bank details for a business partner in SAP, and the Bank Details ID you are entering is already assigned to another bank account for the same partner and partner function/type.
  In SAP, each bank details record for a business partner must have a unique Bank Details ID within the scope of that partner and partner function/type. If you attempt to use an ID that already exists, the system throws this error to prevent duplicate bank details entries.
  
  Explanation
  
  Partner &1: The business partner number.
  Type &2: The partner function/type (e.g., customer, vendor, employee).
  Bank Details ID &3: The identifier for the bank details record.
  
  The system expects that for a given partner and partner type, each bank details ID is unique. Duplicate IDs can cause confusion in payment processing, bank reconciliation, and other financial transactions.
  
  Solution
  
  
  Check Existing Bank Details  
  
  Go to the business partner master data (transaction BP or relevant transaction for your SAP system).
  Navigate to the bank details section for the partner and partner type mentioned.
  Review the existing bank details IDs.
  
  
  
  Use a Unique Bank Details ID  
  
  If the bank details ID you are trying to enter already exists, choose a different, unique ID.
  The ID can be numeric or alphanumeric depending on your configuration, but it must not duplicate an existing ID for the same partner and partner type.
  
  
  
  Delete or Correct Duplicate Entries  
  
  If duplicate bank details exist due to previous incorrect entries, consider deleting or correcting them if business processes allow.
  Ensure that no active transactions depend on the bank details before deletion.
  
  
  
  Check Customizing (if applicable)  
  
  Sometimes, the validation rules for bank details IDs are controlled via customizing.
  Verify if any user-exits or BAdIs are enforcing uniqueness in a specific way.
  
  
  
  
  Additional Information
  
  This error is common in scenarios where multiple bank accounts are maintained for a single partner.
  The Bank Details ID is often used as a key to select the correct bank account during payment runs.
  Proper maintenance of unique bank details IDs helps avoid payment errors and ensures smooth financial operations.
  If you are integrating with external systems or using interfaces, ensure that the bank details IDs are consistent and unique across systems.
