• What is the cause and solution for SAP error message /BOBF/TOOLS_CC004 - ET_FAILED_KEY contains duplicate keys ?

  The SAP error message /BOBF/TOOLS_CC004 ET_FAILED_KEY contains duplicate keys typically occurs in the context of Business Object Processing Framework (BOPF) when there are duplicate keys in the data being processed. This error indicates that the system has encountered multiple entries with the same key in a collection that is expected to have unique keys.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that the data being processed contains duplicate entries for a key that is supposed to be unique. This can happen during data import, data manipulation, or when fetching data from a database.
  Incorrect Logic in Code: If you are using custom code or enhancements, there might be logic that inadvertently creates duplicates.
  Data Consistency Issues: There may be inconsistencies in the underlying database or data model that lead to duplicate keys being generated.
  
  Solution:
  
  Identify Duplicates: Check the data being processed to identify where the duplicates are coming from. You can do this by querying the database or examining the data in the application.
  Data Cleansing: Remove or consolidate duplicate entries in the source data. Ensure that the data being processed adheres to the uniqueness constraints defined in the data model.
  Review Custom Code: If you have custom logic, review it to ensure that it does not create duplicates. Make sure that any data manipulation or retrieval logic is correctly implemented.
  Use Unique Keys: Ensure that the keys used in your BOPF objects are truly unique. If necessary, modify the key structure to include additional fields that can help maintain uniqueness.
  Error Handling: Implement error handling in your code to gracefully manage situations where duplicates might occur, allowing for logging and debugging.
  
  Related Information:
