• What is the cause and solution for SAP error message RSOH028 - Request &1 cannot be locked ?

  The SAP error message RSOH028, which states "Request &1 cannot be locked," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with data requests in the InfoProvider, such as an InfoCube or DataStore Object (DSO). This error indicates that the system is unable to lock a specific data request for processing, which can prevent data loading or processing tasks from completing successfully.
  Causes:
  
  Concurrent Access: Another process or user may be accessing the same request, leading to a lock conflict.
  Long-Running Processes: A previous data load or process may still be running, preventing the new request from being locked.
  System Configuration: Issues with the configuration of the InfoProvider or the data loading process can also lead to locking issues.
  Database Locks: Database-level locks may be preventing the request from being locked in SAP BW.
  Transport Issues: If the request is part of a transport, it may be locked due to transport-related activities.
  
  Solutions:
  
  
  Check for 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 locking the request. If you find any, you may need to wait for them to complete or terminate them if they are stuck.
  
  
  Release Locks: You can use transaction SM12 to check for and release any locks that may be preventing the request from being processed. Be cautious when releasing locks, as this can affect other users or processes.
  
  
  Retry the Request: After ensuring that no other processes are locking the request, try to process the request again.
  
  
  Check System Logs: Review the system logs (transaction SLG1) for any additional error messages or warnings that might provide more context about the locking issue.
  
  
  Database Administration: If the issue persists, consult with your database administrator to check for any database-level locks or issues that may be affecting the SAP BW system.
  
  
  System Configuration Review: Review the configuration of the InfoProvider and the data loading process to ensure that everything is set up correctly.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM66, SM50, SM12, and SLG1 for monitoring and troubleshooting.
  SAP BW Documentation: Review SAP BW documentation for best practices on data loading and request management.
