The SAP error message DMCLG698 indicates that a translation object customizing is locked by a specific user. This typically occurs when a user is currently editing or has an active session that is preventing others from making changes to the same translation object.
Cause: User Lock: The translation object is being edited by another user, which locks the object for other users. Session Timeout: Sometimes, a user may have left a session open, causing the lock to persist even if they are no longer actively working on it. System Error: Occasionally, system errors or crashes can leave locks in place that need to be cleared.
Solution: Identify the User: Check which user is holding the lock. You can do this by using transaction code SM12 (Display and Delete Locks). Look for the lock entry related to the translation object and note the user ID. Contact the User: If possible, contact the user who is holding the lock
