  The SAP error message HCNUSAC_MSG_NEW333 indicating "Cannot lock Summary Structure &1" typically occurs in the context of SAP Human Capital Management (HCM) or related modules when the system is unable to lock a specific summary structure for processing. This can happen for various reasons, including concurrent access by multiple users or processes, or issues with the database.
  Causes:
  
  Concurrent Access: Another user or process is currently accessing or modifying the summary structure, preventing your session from obtaining a lock.

  Configuration Issues: There may be configuration settings that are causing the locking mechanism to behave unexpectedly.
  
  Solutions:
  
  Wait and Retry: If the issue is due to concurrent access, waiting for a few moments and then retrying the operation may resolve the issue.
  Check Active Sessions: Use transaction codes like SM12 to check for active locks in the system. You can identify if another user or process is holding the lock and take appropriate action.
  Transaction Monitoring: Use transaction codes like SM66 to monitor active processes in the system. This can help identify long-running transactions that may be causing the lock.
  Database Administration: If the issue persists, it may be necessary to involve your database administrator to check for any underlying database issues that could be affecting locking behavior.
