• What is the cause and solution for SAP error message TG604 - & : & of & data packages have duplicate-key conflicts ?

  The SAP error message TG604 indicates that there are duplicate-key conflicts in the data packages being processed. This typically occurs during data uploads or data transfers, such as when using tools like LSMW (Legacy System Migration Workbench), BAPIs, or IDocs, where unique keys are expected for records being inserted or updated in the database.
  Cause:
  
  Duplicate Records: The most common cause is that the data being uploaded contains records with keys that already exist in the target database table. This can happen if the source data has duplicates or if the same data is being processed multiple times.
  Incorrect Key Configuration: The configuration of the keys in the target table may not align with the incoming data, leading to conflicts.
  Data Integrity Issues: There may be issues with data integrity in the source system, where records that should be unique are not.
  
  Solution:
  
  Identify Duplicates: Before uploading data, check the source data for duplicates. You can use tools like Excel or SQL queries to identify any duplicate records based on the key fields.
  Data Cleansing: Clean the data to ensure that there are no duplicates. This may involve removing duplicate entries or consolidating records.
  Adjust Upload Logic: If applicable, modify the upload logic to handle duplicates appropriately. For example, you might want to skip records that already exist or update them instead of trying to insert them.
  Check Key Configuration: Ensure that the key fields in the target table are correctly defined and that the incoming data matches these definitions.
  Use Error Handling: Implement error handling in your data upload process to log and manage duplicate key conflicts effectively.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like SE11 (Data Dictionary) to check the structure of the target table and see what fields are defined as keys.
  Data Migration Tools: If you are using LSMW or similar tools, review the mapping and transformation rules to ensure they are set up correctly.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to the TG604 error message.
  Testing: Always test your data uploads in a development or quality assurance environment before executing them in production to catch any potential issues early.
  
  By following these steps, you should be able to resolve the TG604 error and successfully process your data packages without duplicate-key conflicts.
