• What is the cause and solution for SAP error message RSPLS_CR100 - PPM selections for InfoProvider '&1': Buffer is locked ?

  The SAP error message RSPLS_CR100 indicates that there is a locking issue with the buffer for the specified InfoProvider in the context of SAP BW (Business Warehouse) or SAP BW/4HANA. This typically occurs when multiple users or processes are trying to access or modify the same data simultaneously, leading to a conflict.
  Cause:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same InfoProvider at the same time.
  Long-Running Queries: A query or process that is taking a long time to execute may hold the lock longer than expected.
  System Performance Issues: High system load or performance issues can exacerbate locking problems.
  Inconsistent State: The InfoProvider might be in a state that is not consistent due to previous operations that did not complete successfully.
  
  Solution:
  
  Wait and Retry: Often, simply waiting for a few moments and then retrying the operation can resolve the issue, as the lock may be released once the other process completes.
  Identify and Terminate Blocking Processes:
  
  Use transaction SM12 to check for locks. You can see which user or process is holding the lock and decide whether to terminate it.
  If you identify a blocking process that is not critical, you can release the lock by deleting the entry in SM12.
  
  
  Check Long-Running Queries: Use transaction RSRT to monitor and analyze long-running queries. If a query is taking too long, consider optimizing it.
  System Performance: Monitor system performance using transaction ST03N or ST04 to identify any bottlenecks that may be causing delays.
  Batch Jobs: If batch jobs are causing locks, consider scheduling them during off-peak hours to minimize conflicts.
  Consult Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to investigate further, as they can provide insights into system performance and locking mechanisms.

  RSRT: To analyze query performance.
  ST03N: To monitor workload and performance.
  ST04: To analyze database performance.
  
  
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to locking in your version of SAP BW.
  Documentation: Review SAP documentation on locking mechanisms in BW and best practices for managing concurrent access.
