PEP072 - Details

• The SAP error message PEP072 ("Moving is not possible: The target belongs to the task list") typically occurs in the context of Project System (PS) or Production Planning (PP) modules when you are trying to move a project element or a task that is part of a task list. This error indicates that the operation you are attempting is not allowed because the target element is already associated with a task list.
  
  Cause:
  
  Task List Association: The target element you are trying to move is part of a task list, which means it is linked to a specific sequence of operations or activities that cannot be altered without affecting the integrity of the task list.
  Project Structure: The project structure may have dependencies that prevent moving elements around if they are part of a defined sequence or hierarchy.
  Locking Mechanism: The system may have a locking mechanism in place that prevents changes to elements
