We are using V11 and have been asked to create a PO workflow for users Line Manager / Supervisor

I can see under parameters > users > users, and then Organisation we can add in a Supervisor for a user. The field is CHEF(0)

When in User Assignments, I can set a formula for this field. 

The question is do I need to do anything else?, will this pick the User from this field up to send the Workflow VAL / REJ to? Do I need the ADMIN user after the CHEF(0) field

Thanks

Martin
