• What is the cause and solution for SAP error message RLB091 - All data that could be index are locked at present ?

  The SAP error message RLB091, which states "All data that could be indexed are locked at present," typically occurs in the context of the SAP system's indexing process. This error indicates that the system is unable to access the data it needs to create or update an index because that data is currently locked by another process or user.
  Causes:
  
  Data Locking: The most common cause is that the data being indexed is locked by another transaction or user. This can happen if another user is currently processing data in the same table or if a background job is running that locks the data.
  Long-running Transactions: If a transaction takes a long time to complete, it can hold locks on the data for an extended period, preventing other processes from accessing it.
  Database Locks: Locks at the database level can also lead to this error, especially if there are issues with the database configuration or if there are long-running queries.
  Index Maintenance Jobs: If there are scheduled jobs for index maintenance that overlap with other operations, they may cause locks on the data.
  
  Solutions:
  
  
  Identify and Release Locks:
  
  Use transaction codes like SM12 (Display and Delete Locks) to check for existing locks on the data. You can identify the user or process holding the lock and take appropriate action to release it.
  If you find a lock that is no longer needed, you can delete it (if you have the necessary permissions).
  
  
  
  Check Running Transactions:
  
  Use transaction code SM66 (Global Work Process Overview) to see if there are any long-running transactions that might be causing the lock. You can analyze the processes and determine if any can be terminated.
  
  
  
  Review Background Jobs:
  
  Check for any background jobs that might be running and locking the data. Use transaction code SM37 to monitor background jobs and their statuses.
  
  
  
  Optimize Transactions:
  
  If you have control over the transactions that are causing locks, consider optimizing them to reduce their execution time. This can help minimize the time that data is locked.
  
  
  
  Schedule Indexing Jobs Appropriately:
  
  If you are running index maintenance jobs, ensure they are scheduled during off-peak hours to minimize the impact on other transactions.
  
  
  
  Database Configuration:
  
  If the issue persists, consider reviewing the database configuration and settings to ensure that it is optimized for handling locks and concurrency.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or patches related to this error. SAP frequently updates its knowledge base with solutions for common issues.
  Documentation: Review SAP documentation related to data locking and indexing to understand how the system manages locks and how you can configure it for better performance.
  Performance Monitoring: Regularly monitor system performance and locking behavior to proactively address potential issues before they lead to errors.
  
  By following these steps, you should be able to resolve the RLB091 error and ensure that your indexing processes can run smoothly.
