Workflow Log / Object Services

[Parag Joshi]

Friends,
 
I have been looking for this setting for a while now.
 
Scenario:
- Workflow kicked-off via event trigger (Example: Material.Created)
- Workflow does some background processing and ends.
- Under Workflow log for the Material Object (Object Services-Workflow-
Workflow Overview), system displays workflow log, even though all steps were
marked "Not in the Workflow Log".
 
A step or sub-workflow can be set to "Not in workflow log". But is there a way
to turn off the main workflow generating the log?
 
Thanks,
Parag Joshi.
