Basic OD Cost Matrix script not working (error 000732)

TheophileEmmanouilidis — Mon, 21 May 2012 11:31:39 GMT

Dear all,

I've been using modelbuilder to create a basic model of an OD Cost Matrix analysis. I exported it to a python script to create script tool (code below). Unfortunately I keep getting the following error:

"ERROR 000732: Input network analysis layer: Dataset C:\GIS\databases\fullnetwork.gdb\fullnetwork\fullnetwork_ND does not exist or is not supported."

I've also tried "C:/GIS/databases/fullnetwork.gdb/fullnetwork/fullnetwork_ND" but i got the same error.

The model has 4 required parameters (script tool parameters):
- Network / Network Dataset / Input
- Origins / Feature Class / Input
- Destinations / Feature Class / Input
- NA_Output / Feature Class / Output

I really don't understand what I am doing wrong... any advice welcome 🙂

Best regards,
Theo

Make sure your parameter definitions match what you were using for your model. For example, it looks like (from the defaults) that your first argument was a feature layer, not a feature dataset. A way to check this is to open the source model, right click the parameters, and see what data type they are. Your script tool parameter properties should use the same data types.
