• What is the cause and solution for SAP error message CN383 - Select network components only ?

  The SAP error message CN383 ("Select network components only") typically occurs in the context of project management or network planning within the SAP system, particularly when working with network activities in the Project System (PS) module. This error indicates that the user is trying to select or manipulate components that are not valid for the operation being performed, such as selecting non-network components when the system expects only network components.
