Master data

[John A Haworth]

Hi all
 
Could anyone advise me to the following
 
I have set up a workflow making reference to positions and jobs. But as
this is being trransported into UAT and production, and the same positions
and jobs are/will be Master Data, they will be created and maintained in
Production. The agent assignment  within the workflow definition at the
step level, which i have set to 'Positions', is transportable, and uses the
SAP ORG number assignment for the position in DEV(which is going to be
different in Production).
 
Should I therefore be making all agent assignments to either expressions or
roles, and not anything that is going to be maintained as Master Data.
 
Thanks
 
John
