• What is the cause and solution for SAP error message TR104 - Cannot delete lock entry ?

  The SAP error message TR104, which states "Cannot delete lock entry," typically occurs when there is an issue with the lock entries in the SAP system. This error can arise in various scenarios, such as during transport requests or when trying to delete or modify objects that are currently locked.
  Causes:
  
  Active Lock Entries: The lock entry you are trying to delete may still be active or in use by another user or process.
  Authorization Issues: The user may not have the necessary authorizations to delete the lock entry.
  System Errors: There may be inconsistencies or errors in the transport management system or database that prevent the deletion of the lock entry.
