• What is the cause and solution for SAP error message RSSM_TT028 - Object &1(&2) cannot be locked ?

  The SAP error message RSSM_TT028, which states "Object &1(&2) cannot be locked," typically occurs in the context of SAP BW (Business Warehouse) when there is an attempt to lock a particular object (like a query, InfoProvider, or other BW objects) for editing or processing, but the system is unable to do so. This can happen for several reasons:
  Causes:
  
  
  Object Already Locked: The object you are trying to access is already locked by another user or process. This can happen if someone else is currently editing the object or if a previous session did not release the lock properly.
  
  
  Authorization Issues: The user may not have the necessary authorizations to lock the object. This can occur if the user’s role does not include the required permissions.
  
  
  System Issues: There may be underlying system issues, such as database locks or inconsistencies in the BW system that prevent the locking mechanism from functioning correctly.
  
  
  Long-Running Transactions: If there are long-running transactions or processes that are holding locks on the object, it can lead to this error.
  
  
  Solutions:
  
  
  Check for Existing Locks: Use transaction code SM12 to check for existing locks on the object. If you find that another user has locked the object, you may need to wait until they release it or contact them to coordinate access.
  
  
  Release Locks: If you find orphaned locks (locks that are no longer needed), you can release them using transaction SM12. Be cautious when doing this, as it may affect other users.
  
  
  Review Authorizations: Ensure that the user has the necessary authorizations to lock the object. You can check the user roles and authorizations in transaction PFCG.
  
  
  Check for Long-Running Processes: Use transaction SM66 or SM50 to monitor active processes and identify any long-running transactions that may be holding locks. If necessary, you can terminate these processes, but do this with caution.
  
  
  System Restart: In some cases, a system restart may be required to clear any persistent locks or issues. This should be done during a maintenance window and with proper authorization.
  
  
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (for lock entries), SM66 (for global process overview), and PFCG (for role maintenance).
  SAP Documentation: Review SAP documentation related to locking mechanisms in BW and general troubleshooting for locking issues.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to diagnose and resolve the RSSM_TT028 error effectively.
