  The SAP error message CNV_MBT_SHELL098 typically indicates that changes could not be made to a database table during a data migration or conversion process. This error is often encountered in the context of SAP's Migration Cockpit or during data transfer activities, particularly when using the SAP S/4HANA Migration tools.
  Causes:
  
  Database Locking: The table may be locked by another process or transaction, preventing changes from being made.

  Incorrect Configuration: The migration settings or parameters may not be correctly configured, leading to issues when attempting to write to the database.
  
  Solutions:
  
  Check for Locks: Use transaction codes like SM12 to check for any locks on the database table. If locks are found, you may need to wait for the other processes to complete or resolve the locks.
  Review Authorizations: Ensure that the user executing the migration has the necessary authorizations to modify the database tables involved. You may need to consult with your SAP security team.
  Examine Data Integrity: Check for any data integrity issues that may be causing the error. This includes verifying foreign key relationships and ensuring that the data being migrated adheres to the constraints of the target database.
  Check Logs: Review the logs generated during the migration process for any additional error messages or warnings that could provide more context about the failure.
  Database Health Check: Perform a health check on the database to ensure that it is functioning correctly. This may involve checking for issues like disk space, performance bottlenecks, or corruption.
