Hi ,

 

Stuck in a very simple thing it seems . I am trying to call a separate workbench from another by a python caller .Following is the code

 

 

#import fmeobjects

 

import os

 

# Template Function interface:

 

def processFeature(feature):

 

import os

 

os.system("fme.exe MY-WORKBENCH.fmw")

 

 

 

Entry point : processFeature

 

 

 

Error during translation :

 

processFeature

Hi Roy,

 

 

wrong indentations caused the errors. See documents about the Python language e.g. The Python Language Reference > 2. Lexical analysis (2.1.8. Indentation).

 

 

Why not use the WorkspaceRunner transformer?

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Hi Roy,

 

 

if, for some reason, you cannot use the WorkspaceRunner transformer, here is an example of using the fmeobjects API from a Python script. I much recommend this rather than using calls to os.sysytem().
