With the Nighttime Flow Analysis solution, you are able to generate a Sub-DMA and save it to a feature service in ArcGIS. Before creating the Sub-DMA, you will need to update the geoprocessing model to include the DMA feature service information.

To update the geoprocessing model, complete the following steps:

Load DMA to Service geoprocessing model

1. To begin, you will need the id of the DMA feature service for the geoprocessing model. In a web browser, sign in to your ArcGIS organization.
2. Browse to the details page of the DMA feature service and copy the item id.
3. In Windows Explorer, browse to the Maps and GDBs folder and open the SubDMAPlanner.mxd.
4. Open the ArcCatalog window and browse to the DMAPlanner toolbox.
5. Right click the Load SubDMA to Service geoprocessing model and edit.
6. Update the Feature Service Item Id input with the item id of your DMA feature service.
7. Save and close.
