I'm using ArcGIS 10.3
I have two shapefile, one customer and one of Facilities
each shapefile has the field "distributor"
I'm using the tool "Location-allocation_ Network analysis"
I need to keep the groups already established in my Shapefile "Customers" to the field of "distributor
I used the option "GroupName" but it's not possible I have Failed error Solve
Error No feasible solution can be found due to name constraint group
as I can fix the error
