Triggering event through Change Management for Sales order

Question

I am working on three different scenarios of workflow which is triggered on change of sales order.  I am trying to put conditions in SWEC for the workflows to start but not sure how to go about it.  I created change doc object VERKBELEG and assigned bus2032 and changed as my event.  I inserted a value in condition editor like vbap_(fieldname)_new etc.  Nothing seem to be working.
I would like to know once we assign event here in SWEC, should we also assign and activate it in the triggering tab of workflow or just create an entry in the linkage table.
Please guide me as to how I need to work on the sales order change.  I am basically want to trigger a sales order only when a field value is updated or inserted which pertains to my requirement.
Thank you very much.

Karthik,
My problem is still not resolved.  I am trying to put something like this.  Let me know if you have were able to do this in any other way.
