  Incorrect Configuration: The migration configuration might be incorrect, leading to the expectation of an index that does not exist.
  
  Solution:
  
  Check Database Schema: Verify the database schema to ensure that the index in question is indeed missing. You can do this by querying the database or using database management tools.
  Create the Missing Index: If the index is missing and is required for the conversion, you may need to create it manually. Use the appropriate SQL command to create the index based on the specifications provided in the migration documentation.
  Review Migration Settings: Check the migration settings and configuration to ensure that they are correct and that all necessary pre-requisites for the migration are met.
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP frequently releases notes that provide guidance on resolving common issues encountered during migrations.
