I want to calculate a route consisting of 4 points with a script tool and save the results to disk. I need the route to appear as layer on ArcCatalog for continuing working with it (modification of its attribute table).The script tool completes successfully but no output is saved.So, I tried to add the Save To Layer File tool.
I receive the following error message:
#Create a new Route layer. outRouteResultObject=arcpy.na.MakeRouteLayer(in_network_dataset,out_network_analysis_layer=outNALayerName,impedance_attribute=impedanceAttribute,find_best_order="USE_INPUT_ORDER",accumulate_attribute_name=["Length"],output_path_shape="TRUE_LINES_WITH_MEASURES")#Get the layer object from the result object.
