  Authorization Issues: The user account used for the replication may not have the necessary permissions to perform deregistration on the HANA target.
  Schema or Object Locks: If the schema or objects within it are locked or in use, the deregistration process may fail.
  Configuration Errors: Incorrect configuration settings in the SLT or HANA system can lead to issues during the deregistration process.
