• What is the cause and solution for SAP error message /BOBF/TOOLS_CC005 - ET_TARGET_KEY contains duplicate keys ?

  The SAP error message /BOBF/TOOLS_CC005 ET_TARGET_KEY contains duplicate keys typically occurs in the context of Business Object Processing Framework (BOPF) when there are duplicate keys in the target key table during a data operation, such as an update or a delete. This can happen when the system is trying to process a collection of objects and finds that some of the keys are not unique.
  Cause:
  
  Duplicate Entries: The most common cause is that the data being processed contains duplicate entries for the same key. This can happen due to incorrect data preparation or logic in the application that generates the data.
  Incorrect Logic in BOPF Implementation: If the BOPF implementation has logic that does not properly handle unique keys, it can lead to this error.
  Data Consistency Issues: If there are inconsistencies in the data being processed, such as multiple records with the same key in the source data, this error can occur.
  
  Solution:
  
  Check for Duplicates: Review the data being passed to the BOPF operation. Ensure that the entries in the ET_TARGET_KEY table do not contain duplicates. You can do this by querying the data source or using debugging tools to inspect the data.
  Modify Data Preparation Logic: If the duplicates are being introduced by the data preparation logic, modify that logic to ensure that only unique keys are included in the ET_TARGET_KEY table.
  Implement Error Handling: If duplicates are a possibility due to business logic, consider implementing error handling to manage such cases gracefully.
  Debugging: Use the SAP debugger to step through the code where the error occurs. This can help identify where the duplicates are being introduced.
  Consult Documentation: Review the BOPF documentation and any related notes or guides to ensure that the implementation adheres to best practices.
