Load a shapefile as orders in VRP using arcpy

sotokan80_ — Fri, 25 May 2018 10:03:57 GMT

I' m facing the following issue when trying to load a shapefile as orders in VRP solver using arcpy.

The code that i m using:

inOrders = "sortedStops"
orders = arcpy.GetParameterValue("SolveVehicleRoutingProblem_na",0)
orders.load(inOrders)

the errror message that i get;

File "C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcPy\arcpy\arcobjects\arcobjects.py", line 1042, in load
return convertArcObjectToPythonObject(self._arc_object.Load(*gp_fixargs(args)))
RuntimeError: RecordSetObject: Cannot open table for Load

The input shapefile has the following attribute table, which is of course doesn't resemble orders attribute table.

Any suggestions?

What does your orders file look like? It appears to require specific inputs

ok, but how am i supposed to make my orders file with the same format? Another issue is that orders attribute table's fields have many characters whilst mine cannot exceed 10.

i found solution to my problem using MakeVehicleRoutingProblemLayer and arcpy.na.AddLocations instead of SolveVehicleRoutingProblem_na. Thank you very much, for your reply.
