  Authorization Check: Ensure that you have the necessary authorizations to access the class. If not, contact your system administrator to grant the required permissions.
  Consult Documentation: Review any relevant documentation or configuration guides related to the specific SCM process you are working on to ensure that you are following the correct procedures.
