Linking Siebel Workflow to SAP Workflow

[Robert.Verlaat@nuon.com]

Dear All,
 
I would like to know if anyone has experience in linking a Workflow from a
Siebel system to a SAP Workflow? The scenario for us would be: Siebel
Workflow starts a SAP Workflow and waits for feedback of the SAP Workflow
before it continues(including data exchange both ways, of course).
I'am interessed in the high-level points of attention for this scenario.
F.e. prerequisites for Siebel which take a lot time to customize, or other
problems encountered.
 
Thanks,
 
Robert Verlaat
