• What is the cause and solution for SAP error message PEP122 - Scheduling of task &1 cannot be deleted ?

  The SAP error message PEP122, which states "Scheduling of task &1 cannot be deleted," typically occurs in the context of Project Management (PS) or Production Planning (PP) when there is an attempt to delete a scheduled task that is not allowed to be removed. This can happen for several reasons:
  Causes:
  
  Task Dependencies: The task may have dependencies or relationships with other tasks that prevent it from being deleted.
  Status of the Task: The task might be in a status that does not allow deletion (e.g., it could be completed, closed, or in progress).
  Assigned Resources: If resources are assigned to the task, it may not be possible to delete it until those assignments are removed.
  Project Structure: The task may be part of a larger project structure that enforces certain rules regarding task management.
  User Authorizations: The user may not have the necessary authorizations to delete the task.
  
  Solutions:
  
  Check Task Status: Verify the status of the task. If it is completed or closed, you may need to change its status before attempting to delete it.
  Remove Dependencies: If there are dependencies, you will need to remove or adjust them before deletion.
  Unassign Resources: Ensure that all resources assigned to the task are unassigned.
  Review Project Structure: Check if the task is part of a project structure that restricts deletion. You may need to adjust the project plan or hierarchy.
  User Permissions: Ensure that you have the necessary permissions to delete the task. If not, contact your SAP administrator to obtain the required authorizations.
