• What is the cause and solution for SAP error message /PLMB/BA_CCK018 - Parameter variant &1 is locked by user &2 ?

  The SAP error message /PLMB/BA_CCK018 Parameter variant &1 is locked by user &2 indicates that a specific parameter variant (identified by &1) is currently locked by another user (identified by &2). This typically occurs in the context of configuration or parameter settings within the SAP system, particularly in the PLM (Product Lifecycle Management) module.
  Cause:
  
  User Locking: The parameter variant is being edited or used by another user, which prevents other users from making changes to it simultaneously.
  Session Issues: Sometimes, a user may have left a session open, causing the lock to persist even after they have stopped actively using it.
  System Configuration: Certain configurations may inherently lock parameters to prevent concurrent modifications.
  
  Solution:
  
  Wait and Retry: If the user who has locked the parameter variant is actively working on it, the simplest solution is to wait until they finish and release the lock.
  Identify the Locking User: You can check who is currently locking the parameter variant by using transaction code SM12 (for lock entries) or SM21 (for system logs) to identify the user and the session.
  Unlock the Parameter: If the locking user is no longer active or if the lock is stale, an administrator can manually unlock the parameter variant. This can be done in SM12 by finding the relevant lock entry and deleting it.
  Communicate with the Locking User: If possible, reach out to the user who has locked the parameter to coordinate the release of the lock.
  Review Configuration: If this issue occurs frequently, it may be worth reviewing the configuration and usage of parameter variants to ensure that they are not being locked unnecessarily.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage lock entries) and SM21 (to check system logs).
  User Management: Ensure that users are trained on how to properly release locks and manage their sessions to avoid unnecessary locking.
  System Performance: Frequent locking issues may indicate a need for better session management or user training to optimize system performance and usability.
