Problem: Cannot move network features that participate in a composite relationship
When attempting to move network features, an error is returned listing the following messages:
"The feature(s) could not be moved"
"Failed to move related features [feature class name]"
Connected network features cannot participate in a composite relationship with each other. The destination feature is messaged to move twice, once in the network and again in the composite relationship.
Solution or Workaround
Composite relationships cannot be maintained between network features that are connected to one another. If edits need to be made, the relationship should be removed or a simple relationship class should be used.
