  Review Configuration: Ensure that the configuration settings in GTS and related modules are correct. Consult the documentation or your system administrator for guidance.
  System Logs: Check the system logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  Database Health Check: Perform a health check on the database to ensure that it is functioning correctly and that there are no underlying issues causing locking problems.
