  The SAP error message TFW_API021 indicates that there is an attempt to insert a record into the table TFW_MINITP that already exists. The message specifies that an entry with the key values provided (represented as &1, &2, and &3) is already present in the table. This typically occurs during data processing or when trying to create a new entry in a table that requires unique keys.
  Cause:
  
  Duplicate Entry: The most common cause of this error is that the system is trying to insert a record with a primary key or unique constraint that already exists in the TFW_MINITP table.
  Data Migration or Upload: If you are performing a data migration or bulk upload, it is possible that the data being uploaded contains duplicates.
  Incorrect Logic in Custom Code: If there is custom ABAP code or a program that is inserting records into this table, it may not be checking for existing records before attempting to insert.
  
  Solution:
  
  Check for Existing Records: Before inserting a new record, check if an entry with the same key already exists in the TFW_MINITP table. You can do this by executing a SELECT query in the database.
  SELECT * FROM TFW_MINITP WHERE key_field1 = '&1' AND key_field2 = '&2' AND key_field3 = '&3'.
  
  Modify the Insert Logic: If you are using custom code, modify the logic to handle duplicates appropriately. You can either skip the insert if the record exists or update the existing record if that is the desired behavior.
  Data Cleansing: If the error occurs during data migration, ensure that the data being migrated does not contain duplicates. Clean the data before the upload.
  Error Handling: Implement error handling in your code to catch this specific error and take appropriate action, such as logging the error or notifying the user.
