  Cause:
  
  Exclusion of Activities: The error is triggered when certain activities are excluded from the planning process, which can lead to a situation where the resource network cannot be properly scheduled.

  Solution:
  
  Review Exclusions: Check the activity exclusions in the planning book or the relevant configuration settings. Ensure that the exclusions are necessary and correctly defined.
  Adjust Resource Allocation: If possible, adjust the resource allocation to ensure that the required resources are available for the activities that need to be scheduled.
