  Review Migration Steps: If this error occurred during a migration, review the steps taken during the migration process to identify any potential issues that may have led to the overwriting of TKA00.

  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion tool you are using. There may be specific guidelines or patches available to address this issue.
