Hello, I am trying to run several OD Cost Matrix analyses using the Network Analyst package. I was able to successfully run it once based on a network dataset I created from my local roads layer in addition to my own origin and destination point layers. However, the tool only works for a maximum of 1000 origin points, but I need to perform this analysis on around 3,000 origin points (against only 5 destination points). Because of this, I separated out my origin point layer into three groups. As I said, the first group ran successfully and I was able to generate travel times (in minutes) for all my points in that layer. However, I tried to create a new OD Cost Matrix layer for the rest of my origin points, set up the tool and inputs exactly the same as before, but now for some reason I am unable to select a Mode (Driving time, driving distance, etc). Instead, the Mode window just says "<custom>, ft" with no ability to select from the drop-down menu - even though I have the exact same network dataset layer added into the map. I have retried running the tool both on the same map, as well as on a new map, and I've also tried recreating an identical feature dataset containing an identical network dataset, but I cannot get the tool to let me select my preferred travel mode (drive time in minutes). When I hover over the Mode, it says "This command is currently unavailable. The current network data source does not have any travel modes". I just don't understand how it worked the first time but not when I try again using the exact same inputs and parameters? Has anyone run into a similar problem, and/or found a solution to this? Is there some place I can directly connect my network dataset into the OD cost matrix layer aside from simply having them contained in the same map to ensure that the travel mode can be based off my network dataset?
