  Review Index Status: Check the status of the indexes in the database to understand why they are inactive. You can use database management tools or SQL queries to review the index status.
  Rebuild or Activate Indexes: If you determine that certain indexes should be active, you can rebuild or activate them as necessary. This can typically be done through the database management interface or using SQL commands.
  Performance Monitoring: Monitor the performance of your database and application to ensure that the inactive indexes are not impacting performance negatively.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or transformation process you are executing for any additional guidance.
