  The SAP error message CM_SERVICE_ADMIN446 indicates that the customizing settings for synchronous generation are locked by a specific user. This typically occurs in the context of SAP's Customizing Management, where certain configurations or settings are being modified or accessed by a user, preventing others from making changes simultaneously.
  Cause:
  
  User Lock: The error is primarily caused by a user having an active lock on the customizing settings. This can happen if a user is currently editing the settings or if a previous session did not close properly.
  Transaction in Progress: If a transaction related to synchronous generation is still in progress, it can lead to this lock.
  System Error: Occasionally, system errors or crashes can leave locks in place that need to be cleared.
