• What is the cause and solution for SAP error message CN071 - Activity can only differ between internal and external processing ?

  The SAP error message CN071 ("Activity can only differ between internal and external processing") typically occurs in the context of project management and controlling, particularly when dealing with activity types in SAP Project System (PS) or Controlling (CO) modules.

  Cost Element Assignment:
