Email Expressions are Blank in Sub-workflow Created for MDG

Hello Workflow Experts,

I just posted a question in the Master Data Governance discussion area but it is more workflow related than MDG so posting the link here in hopes that someone can help me out.

In summary, I am trying to create a sub-workflow thats sends an email to the creator of a MDG change request, once the change request is approved.

I am having difficulties in two areas.  I am new to SWDD workflows so any advice is greatly appreciated.

Two issues:

1. The expressions I am using to display the Change Request Number and the Change Request Description are not returning values to my email – they are blank.
2. I want to send the email to the person that created the MDG Change Request but I can’t figure out how to determine the creator (i.e., CR Requestor) of the MDG Change Request and ultimately, their email address.  Right now I am testing using my own email address in the workflow Send Mail step.

Here is the full detail of my question, with lots of screen shots, over in the MDG discussion group: http://scn.sap.com/thread/3513244

Sincere thanks,

Rob Scofield
