Time Zone Attribute greyed out

GeoRikerHH — Sun, 26 Jan 2025 13:16:58 GMT

hi,

The Last Mile Delivery Solver in teh Network Analyst needs a Network Dataset having a Time Zone Attribute.

Unfortunately whatever I do the "Add Time Zone Attribute" is always greyed out. I followed the official instructions to add a Time Zones Table with the only time zone (W Europe) but that didnt solve the problem. I then also added a second time zone to my time Zoens Table and added the TimeZoneID to my Streets that I use for my Network (OSM based).

Is tehre another precondition to activate the time zone attribute in a Network Dataset, that I might not be aware of?

Best

David

Make Last Mile Delivery Analysis Layer (Network Analyst)—ArcGIS Pro | Documentation

The analysis network used for a last mile delivery analysis must have at least one travel mode, one cost attribute with time units, and one cost attribute with distance units, as well as a time zone attribute.

From the above and the rest of the link, it sounds like these preconditions need to be met before you add locations

This link also suggests the procedure and how to rebuild the network

Do you see this warning flag when you open the network dataset properties?

If you see that, then you need to first remove from the map the network dataset and any network analysis layers that reference it. Certain properties of the network aren't editable when the network is open in the map.

@MelindaMorang Hello, I am updating my existing Network Dataset from an 11.2 to an 11.5 where I don't believe that the Last Mile option was available back then. As my organization will not need this, is there a possibility to just not enable this for the PublishingRoutingServices process?

@amarcz_cc If you use publish routing services utility tool, you can specify a -S parameter, and pass all the solvers you want, except "LastMileDelivery". EG:

-S Route,ClosestFacility,ServiceArea,OriginDestinationCostMatrix,Location-Allocation,VehicleRoutingProblem
