Run FME workspace using python

I'm trying to run a second workspace using python command in "Shutdown Python Script" in the first workspace using the following command. But its giving me an error. Is there anything I need to do different? I am using FME 2012 SP 2

Thanks, Sam

So as suggested by Safe tech support, I created a batch file with the following code:

fme.exe c:\test2.fmw --SourceDataset_ARCGIS_LAYER C:\ScratchParcel\DevEnv.gdb\AddressPoint --DestDataset_SHAPE C:\temp

and added the following code in the shutdown python script window:

import os os.system("C:\\temp\\test.bat")

When I run it, although it says transaction was successful, I don't get any results i.e., the output shapefile is not created.

Answer

Your Python doesn't look syntactically valid. Try

import os
os.system("fme.exe C:\\temp\\test2.fmw --SourceDataset_ARCGIS_LAYER C:\\ScratchParcel\\DevEnv.gdb\\AddressPoint --DestDataset_SHAPE C:\\temp")

I've added the parens and quotes around the string you are passing to os.system, and escaped the backslashes.

Update: In addition, the fme.exe in your path is different than the fme.exe being run by Workbench. Explicitly specify the path to the fme.exe you want to run:

os.system("c:\\pathToFme\\fme.exe test2.fmw")

or, perhaps in this more future proof manner

os.system(os.path.join(os.environ['FME_HOME'], "fme.exe") + " test2.fmw")

which says "run using the fme.exe that we are currently running".
