I preface all of this by explaining that I'm not a Python developer (I usually use PHP and Java) nor do I use the ArcGIS product. I've been attempting to use Python to assist a colleague but I'll try to provide all the information I can.

Our aim is to use a Python script that utilises toolboxes to update data. There are two sources of data for the model: one from DataInteroperability and the other files on a mapped drive. My current code is below:

import arcpy

if arcpy.CheckExtension("DataInteroperability") == "Available":
   print "Checked out \"DataInteroperability\" Extension"
   print "Data Interoperability license is unavailable"

arcpy.Land.ScheduledLandCharges("Interoperability Connections\\ScheduledConversionLandCharges.fdl\\Assets_of_Community_Value Polygon","Q:\\Shp_Files\\Land_Charges")

When this is run I receive the following error:

Traceback (most recent call last): File "Jonathan2.py", line 10, in arcpy.Land.ScheduledLandCharges("Interoperability Connections/ScheduledConversionLandCharges.fdl/Assets_of_Community_Value Polygon'","Q:\Shp_Files\Land_Charges")

File "G:\data\Toolbox\ScheduledLandChargesConversion.tbx", line 25, in ScheduledLandCharges

arcgisscripting.ExecuteError: Failed to execute. Parameters are not valid.

ERROR 000732: Assets_of_Community_Value Polygon: Dataset Interoperability Connections/ScheduledConversionLandCharges.fdl/Assets_of_Community_Value Polygon' does not exist or is not supported

The value does not exist.

ERROR 000732: Input Features: Dataset 'Interoperability Connections/ScheduledConversionLandCharges.fdl/Assets_of_Community_Value Polygon'' does not exist or is not supported

Failed to execute (ScheduledLandCharges).

I think this is because I'm passing the model the wrong kind of input, as it's after a feature layer. I've copied the text for the DataInteroperability "path" from the toolbox's Python export, so that may be what's going wrong. The model in question (ScheduledLandCharges) requires the following:

Help on function ScheduledLandCharges:

ScheduledLandCharges(Assets_of_Community_Value_Polygon=None, Land_Charges=None)
    ScheduledLandCharges_Land(Assets_of_Community_Value_Polygon, Land_Charges)


     Assets_of_Community_Value_Polygon (Feature Layer)
     Land_Charges (Folder)

    Inside ArcMap, try copying your data interop connection, pasting it in c:\temp or somewhere and updating your code within the script to reference the full path. Thats in contrast to referencing the virtual path from that node.

It appears that your one of the input data is incorrect. The connection name(fdl) files exists on disk and may need to be passed as a parameter (as path on disk) Default Location : C:\Users\\AppData\Roaming\Safe Software\Interoperability\ConnectionName.fdl\LayerName

  • Many thanks, this appeared to be the problem, that and mapping a drive that was shown in the FDL file. Jun 22, 2018 at 9:10
