I have 177 points of origin and 177 of destination. There's should be 31.329 lines generated by OD cost matrix, but there's only 2077 lines. I've made sure that all the points are on the traversable network, and i already checked the network with topology. I've unchecked the oneway prohibition and hierarchy option, but it still only generated 2077 lines, and when i isolated all the 128 points which don't have lines and ran OD cost matrix, only 33 from 128 points now have lines. What should i do to fix this?
the pink points are all the 128 error points which don't have lines (blue selection mark) shown in picture below
I'm using arcmap 10.2 with network analyst extension.
