• What is the cause and solution for SAP error message IR004 - Lock management not available -> only display possible ?

  The SAP error message IR004 ("Lock management not available -> only display possible") typically occurs when the system is unable to acquire a lock on a particular object or resource due to various reasons. This can happen in different contexts, such as when trying to edit or update data in a transaction that requires exclusive access.
  Causes:
  
  Lock Table Full: The lock table may be full, preventing new locks from being created.
  Lock Conflict: Another user or process may already hold a lock on the object you are trying to access.
  System Configuration: There may be configuration issues in the SAP system that prevent lock management from functioning correctly.
  Database Issues: Problems with the underlying database can also lead to lock management issues.
  User Authorizations: The user may not have the necessary authorizations to acquire locks on certain objects.
  
  Solutions:
  
  Check Lock Entries: Use transaction code SM12 to check for existing lock entries. You can identify if there are locks held by other users that are preventing your access.
  Release Locks: If you find unnecessary locks, you can release them (if you have the necessary authorizations) or ask the user holding the lock to release it.
  Increase Lock Table Size: If the lock table is full, consider increasing its size. This can be done by adjusting the profile parameters in the SAP system.
  Review System Configuration: Ensure that the system is properly configured for lock management. Check the relevant parameters in the instance profile.
  Check User Authorizations: Verify that the user has the necessary authorizations to perform the action that requires a lock.
