Jay,
Thanks very much for the response. Calculate Locations tool created a good working feature class with all the location fields necessary to correlate to my street network file. They both reside in a FGDB Dataset along with a successfully built Network Dataset derived from my street file.
Unfortunately, when I attempt to add only the Shelter features from my Buildings feature class to my Network Analysis Layer's Facilities sub-layer - by using the Search Query option in the Add Location tool - Add Locations adds all the features in the feature class. The SQL expression the Query Builder creates is being ignored for some reason. The buildings feature class certainly has a type field with "Shelter" records to select. Everything appears fine and I simply want to add X # of Shelter features as Facilities and X # of say Foster Care offices as Incidents. The Buildings feature class is a Source for the Network Dataset and appears in the Add Location tool's dialogue at the bottom - as a choice for the search query option. The expression is simply Type = 'Shelter' but it has no effect. What am I missing here?
Thanks, Jim
