• Message number: 074

• Message text: Lock on InfoProvider '&1' is preventing indexing

What causes this issue?

At the time the BWA index was activated, a process (probably a query)
was running on an InfoProvider that includes the object for this table.
This process is still running. Because new entries could be generated in
the SID table with this process, the process has to finish before the
table can be indexed.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message RSD_TREX074 - Lock on InfoProvider '&1' is preventing indexing ?

  The SAP error message RSD_TREX074 indicates that there is a lock on the InfoProvider, which is preventing the indexing process from proceeding. This typically occurs in the context of SAP BW (Business Warehouse) when the system is trying to index data for a particular InfoProvider, but it cannot do so because the InfoProvider is currently locked by another process.
  Cause:
  
  Active Processes: Another process (such as data loading, data extraction, or a query execution) is currently using the InfoProvider, which results in a lock.
  Long-running Transactions: If a transaction is taking too long to complete, it can hold the lock for an extended period.
  System Configuration: Configuration settings or issues in the system can lead to locks not being released properly.
  
  Solution:
  
  
  Identify the Locking Process:
  
  Use transaction code SM12 to check for locks on the InfoProvider. You can filter by the object name or user to find the specific lock.
  Identify the user or process that is holding the lock.
  
  
  
  Terminate the Locking Process:
  
  If the locking process is no longer needed, you can terminate it. This can be done through transaction SM37 (to find the job) or SM12 (to delete the lock entry).
  Be cautious when terminating processes, as this may lead to data inconsistencies or loss of unsaved work.
  
  
  
  Check for Long-running Jobs:
  
  Review any long-running jobs that may be causing the lock. If necessary, you can adjust the scheduling of these jobs to avoid conflicts.
  
  
  
  Retry Indexing:
  
  Once the lock is released, you can retry the indexing process. This can be done through the relevant transaction or program that initiates the indexing.
  
  
  
  Monitor and Optimize:
  
  Monitor the system for frequent locking issues. If this is a recurring problem, consider optimizing the data loading processes or reviewing the system configuration to minimize locks.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM12: To view and manage locks.
  SM37: To monitor background jobs.
  RSCONN01: To check the connection to the BW system.
  
  
  
  Documentation: Refer to SAP Notes and documentation related to your specific version of SAP BW for more detailed troubleshooting steps and best practices.
  
  
  Performance Tuning: Regularly review and optimize data loading and extraction processes to reduce the likelihood of locks.
  
  
  By following these steps, you should be able to resolve the RSD_TREX074 error and successfully index the InfoProvider.
