How to Lock /Unlock TMS for an SAP System


In certain circumstances, you may want to lock an SAP System for TMS accesses. If you have to stop an SAP System for hardware maintenance, for example, communicate this to the other SAP Systems in the transport domain. This prevents unnecessary attempts to access an SAP System that cannot be reached.
Locked SAP Systems are not displayed in the import overview. Display and import functions are not available for SAP Systems that have been locked.


Procedure


To lock an SAP System:
  1. Log onto the SAP System functioning as the transport domain controller.
  2. Enter Transaction STMS.
  3. Choose Overview ® Systems. The system overview appears.
  4. Position the cursor on the SAP System you want to lock.
  5. Choose SAP System ® Lock.
  6. Confirm the prompt and distribute the configuration.
The SAP System has been locked for the TMS. All SAP Systems belonging to the transport domain are informed that the SAP System has been locked.
