Network Analyst Routing: Failure while working with internal OD cost matrix problem instance.

[Sarah_Girdwood]

I am trying to run a vehicle routing problem using model builder and I get the error: failure while working with internal OD cost matrix problem instance.

• I have solved a vehicle routing problem using the same orders, depots, routes and routable layer before (in the network analyst window)
• I have deselected all restrictions 
• I have checked "ígnore all invalid locations''
• there are +4000 orders and 250 depots

I initially had memory issues but have rectified this.

Does anyone have any ideas of what I could do to solve this problem?

Thanks #vehicleroutingproblem #networkanalyst #routablelayer

Problem solved - incorrectly copied network dataset was the cause.
