001744: There is no eligible feature class to add to the current facility network.

Description

There is either no feature class or the existing feature class is invalid and cannot be added to the current facility network.

Solution

Make sure the feature class you are adding exists in the feature dataset where the facility network resides. The input feature class cannot participate in a geometric network, network dataset, parcel fabric, the current facility network, or another facility network. It can, however, participate in a topology.
