This typically occurs in the context of workflow processes or task management within SAP systems, particularly in the context of change management or transport management.
  Cause:
  The error arises when:
  
  A task (Task &1) is trying to execute, but it is dependent on another task (Sign-off Task &2) that has not been locked.
