  The SAP error message /CFG/APPL_BCW_SRV902 indicates that there was an issue with the enqueue semaphores during a Business Configuration Workbench (BCW) update. This error typically arises in the context of configuration changes or updates in the SAP system, particularly when multiple users or processes are trying to access or modify the same configuration data simultaneously.
  Causes:
  
  Concurrency Issues: Multiple users or processes trying to access the same configuration data can lead to conflicts, resulting in enqueue errors.

  Configuration Errors: There may be issues with the configuration settings or inconsistencies in the BCW setup.
  
  Solutions:
  
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. If there are stale or unnecessary locks, they can be deleted (if you are sure they are not in use).
  System Performance Monitoring: Monitor system performance using transaction codes like ST22 (dump analysis) and SM66 (global work process overview) to identify any bottlenecks.
  Increase Lock Table Size: If the lock table is full, consider increasing its size. This can be done by adjusting the profile parameters enque/table_size in the instance profile.
  Review Configuration Changes: Ensure that the configuration changes being made are valid and do not conflict with existing settings.
  Retry the Operation: Sometimes, simply retrying the operation after a short wait can resolve transient issues.
