• What is the cause and solution for SAP error message PSHLP_MSG_CL004 - Not all objects were locked; see lock log ?

  The SAP error message PSHLP_MSG_CL004 indicates that not all objects could be locked during a transaction, and it suggests checking the lock log for more details. This error typically occurs in the context of SAP's Project System (PS) or when dealing with object locking in general.
  Cause:
  
  Concurrent Access: Another user or process may be accessing the same objects, preventing them from being locked.
  Lock Table Overflow: The lock table may be full, which can happen if there are too many locks being held or if the system is not configured to handle the required number of locks.
  Authorization Issues: The user may not have the necessary authorizations to lock certain objects.
  System Configuration: There may be configuration issues in the SAP system that affect how locks are managed.
  Database Issues: Problems with the underlying database can also lead to locking issues.
  
  Solution:
  
  Check Lock Log: Use transaction code SM12 to view the lock entries. This will help identify which objects are currently locked and by whom.
  Release Locks: If you find that locks are held by users who are no longer active, you can manually delete those locks (if you have the necessary authorizations).
  Increase Lock Table Size: If the lock table is full, consider increasing its size. This can be done by adjusting the parameters in the SAP profile (e.g., enque/table_size).
  Review Authorizations: Ensure that the user has the necessary authorizations to lock the required objects.
  Check for Long-Running Transactions: Identify and resolve any long-running transactions that may be holding locks for an extended period.
  System Monitoring: Regularly monitor the system for lock contention and performance issues to prevent future occurrences.
