• What is the cause and solution for SAP error message RSM1122 - Unable to delete indexes for cube &1, because no lock can be set ?

  The SAP error message RSM1122 indicates that the system is unable to delete indexes for a specific InfoCube because it cannot set a lock on the object. This typically occurs during the process of data management in SAP BW (Business Warehouse) when trying to delete or modify indexes associated with an InfoCube.
  Causes:
  
  Active Processes: There may be active processes or jobs that are currently using the InfoCube, preventing the system from obtaining a lock.
  Long-running Queries: If there are long-running queries or data loads that are accessing the InfoCube, the system will not be able to set a lock.
  Database Locks: There might be database-level locks that are preventing the operation.
  User Sessions: Other user sessions may be holding locks on the InfoCube.
  System Configuration: Configuration issues or inconsistencies in the BW system can also lead to this error.
  
  Solutions:
  
  
  Check Active Processes: Use transaction codes like SM66 (Global Work Process Overview) or SM50 (Work Process Overview) to check for any active processes that might be using the InfoCube. If you find any, you may need to wait for them to complete or terminate them if appropriate.
  
  
  Monitor Queries: Check for any long-running queries that might be accessing the InfoCube. You can use transaction RSRT (Query Monitor) to identify and manage queries.
  
  
  Database Locks: Use transaction SM12 (Display and Delete Locks) to check for any locks on the InfoCube. If you find locks that are no longer needed, you can delete them, but be cautious as this may affect other users.
  
  
  User Sessions: Ensure that no other users are currently accessing the InfoCube. You can check user sessions using transaction AL08 (Global User Overview).
  
  
  Retry the Operation: After ensuring that no locks are present, retry the operation to delete the indexes.
  
  
  System Restart: In some cases, a system restart may help clear any lingering locks or processes that are not releasing resources properly.
  
  
  Consult SAP Notes: Check 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 SM66, SM50, SM12, and RSRT for monitoring and managing processes and locks.
  SAP BW Documentation: Review SAP BW documentation for best practices on managing InfoCubes and indexes.
