030183: Your network data source is 3D, but your input points are 2D. Points will be located on the network as if the network were in a 2D plane, ignoring the network's Z coordinates.

Description

The input points are 2D. The z-coordinates of the network data source will be ignored, and the points will be located on the network as in a 2D plane.

Solution

If this is not the expected behavior, use 3D input locations with the same z-coordinate system as the network dataset.
