Hi there,
I'm generating large OD matrices with ArcGIS. My idea is to use the same input file for origins and destinations. However, when I load the destinations, ArcGIS change de ID's. As a result, different IDs are assigned to a same location in the OD matrix. What I need is origins and destination with same IDs to warranty that total OD-distance, for example, from ID 1 to ID 1 is 0.
Any advice about it??

You could possibly do the OD analysis with whatever ID's and later do a spatial join to bring in the correct ID's. Makes sense ? Because everything in ArcGIS is about coordinates and less about ID's. As long as your geographic locations are correct, you can make your results look as you want with some tricks.
Thanks
