[GIS] Has anybody used arcpy.mapping.ExportReport successfully on 64bit machine

64bitarcgis-10.1arcpybackground-geoprocessingreports

The online help for arcpy.mapping.ExportReport says that it has some restrictions on use but does not list 64bit machines amongst them.

I am running the following test from IDLE under ArcGIS 10.1 SP1 (with 64bit Background Geoprocessing installed) on Windows 7 SP1.

I've create a simple test.mxd (one layer called Suburbs in data frame called Layers) and a simple test.rlf (included Suburbs, said Finish to take all defaults, saw report and saved it as *.rlf)

However, this code (more or less straight from the Help example):

import arcpy
mxd = arcpy.mapping.MapDocument(r"C:\temp\test.mxd")
df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]
lyr = arcpy.mapping.ListLayers(mxd, "Suburbs", df)[0]
arcpy.mapping.ExportReport(lyr,
                           r"C:\temp\test.rlf",
                           r"C:\temp\test.pdf")
del mxd

throws this error:

Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win32

RuntimeError: Error in generating report

Any thoughts on cause and/or possible workaround are welcome!
(My suspicion is that ExportReport may not be supported on 64bit machines.)

Best Answer

It will work on a 64 Bit Machine, yes, but only from the 32 bit Python interpreter. It is documented:

The ExportReport function has a dependency on the ArcMap installation. Therefore, ExportReport can only be executed on machines that have ArcMap installed. ExportReport will not run using stand-alone installations of ArcGIS Engine or ArcGIS for Server. Moreover, ExportReport will not work as a Geoprocessing Service.

64-Bit Background geoprocessing is a stand-alone installation.
