• What is the cause and solution for SAP error message /BOBF/LIBRARY024 - Locking mode invalid ?

  The SAP error message /BOBF/LIBRARY024 Locking mode invalid typically occurs in the context of the Business Object Processing Framework (BOPF) in SAP. This error indicates that an invalid locking mode has been specified when trying to perform an operation on a business object.
  Cause:
  
  Invalid Locking Mode: The error is primarily caused by specifying a locking mode that is not recognized or supported by the BOPF framework. Locking modes are used to control how records are locked during transactions to prevent concurrent modifications.
  Configuration Issues: There may be issues in the configuration of the business object or the way the locking modes are defined in the BOPF implementation.
  Custom Code: If there is custom code that interacts with BOPF, it may be incorrectly specifying the locking mode.
  
  Solution:
  
  
  Check Locking Mode: Review the code or configuration where the locking mode is being set. Ensure that the locking mode being used is valid. Common locking modes include:
  
  LOCK_MODE_EXCLUSIVE: Exclusive lock.
  LOCK_MODE_SHARED: Shared lock.
  LOCK_MODE_NONE: No lock.
  
  Make sure that the locking mode you are trying to use is defined in the BOPF framework.
  
  
  Review BOPF Configuration: Check the BOPF configuration for the business object in question. Ensure that the locking modes are correctly defined and that there are no discrepancies in the configuration.
  
  
  Debugging: If the issue persists, consider debugging the BOPF call to see where the invalid locking mode is being set. This may involve checking the method calls and parameters being passed.
  
  
  Consult Documentation: Refer to the SAP documentation for BOPF to understand the valid locking modes and their usage. This can provide insights into what might be going wrong.
