• What is the cause and solution for SAP error message CNV_CMIS_M037 - DDIC Index &1 exists already for table &2 ?

  The SAP error message CNV_CMIS_M037 indicates that there is an attempt to create a Data Dictionary (DDIC) index that already exists for a specified table. This typically occurs during data migration or conversion processes, particularly when using tools like SAP's Conversion Management Information System (CMIS).
  Cause:
  The error arises when:
  
  A migration or conversion process tries to create an index on a database table that already has an index with the same name.
  There may be a conflict due to previous migration attempts or existing configurations in the system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Indexes:
  
  Use transaction code SE11 (Data Dictionary) to check the existing indexes on the specified table. Look for the index name mentioned in the error message.
  If the index already exists and is valid, you may not need to create it again.
  
  
  
  Modify Migration Settings:
  
  If the index is not needed or if the migration process can proceed without it, you may need to adjust the migration settings to skip the creation of this index.
  
  
  
  Drop the Existing Index:
  
  If the existing index is not required, you can drop it using transaction SE11 or SE14 (Database Utility). Be cautious with this approach, as it may affect other processes relying on that index.
  
  
  
  Review Migration Scripts:
  
  If you are using custom scripts or programs for migration, review them to ensure they are not attempting to create indexes that already exist.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific migration or conversion process you are executing. There may be specific guidelines or updates that address this issue.
  
  
  
  Contact SAP Support:
  
  If the issue persists and you cannot determine the cause, consider reaching out to SAP support for assistance. They may provide insights based on the specific context of your system and migration.
  
  
  
  Related Information:
  
  Transaction Codes: SE11 (Data Dictionary), SE14 (Database Utility), SE80 (Object Navigator).
  SAP Notes: Check for any relevant SAP Notes that might address known issues with the migration process or specific error messages.
  Migration Tools: Familiarize yourself with the tools and processes involved in your data migration, as they may have specific configurations or requirements.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
