• What is the cause and solution for SAP error message FKC_MIG009 - Double key for interest document &1 in table &2. Interest doc. ignored ?

  The SAP error message FKC_MIG009 indicates that there is a double key for an interest document in the specified table, which means that the system has detected duplicate entries for an interest document that should be unique. This typically occurs during data migration or when processing interest documents in the financial module.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are duplicate entries in the database table for the interest document. This can happen due to incorrect data migration, manual data entry errors, or issues with data extraction processes.
  Data Consistency Issues: If the data in the source system was not consistent or had duplicates before migration, this could lead to the same issue in the target system.
  Configuration Issues: Sometimes, configuration settings in the SAP system may lead to the generation of duplicate keys.
  
  Solution:
  
  
  Identify Duplicates: Use SQL queries or SAP transaction codes (like SE16 or SE11) to check the specified table for duplicate entries. You can look for the interest document number and see how many times it appears.
  Example SQL query:
  SELECT interest_document_number, COUNT(*)
  FROM <table_name>
  GROUP BY interest_document_number
  HAVING COUNT(*) > 1;
  
  
  Remove Duplicates: Once you identify the duplicates, you will need to decide how to handle them. This could involve:
  
  Deleting the duplicate entries if they are not needed.
  Merging the data if there are differences that need to be preserved.
  Correcting the data in the source system before re-migrating.
  
  
  
  Check Migration Process: If this error occurred during a migration process, review the migration logic to ensure that it correctly handles duplicates. You may need to adjust the extraction or transformation steps to prevent duplicates from being created.
  
  
  Review Configuration: Check the configuration settings related to interest document processing to ensure that they are set up correctly and do not allow for the creation of duplicate keys.
  
  
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide guidance on handling similar issues.
