This message indicates that there is no network activity associated with the project or work breakdown structure (WBS) element you are trying to work with, and as a result, the system is defaulting to the dates from the WBS element.
  Cause:
  
  No Network Activity Defined: The primary cause of this error is that there are no network activities defined for the project or WBS element you are trying to access. In SAP, network activities are essential for scheduling and managing project timelines.
  Incorrect WBS Element: The WBS element you are trying to use may not have any associated network activities, or it may not be correctly set up.
