Query on Business rule wrt Assignemnt group and Assigned to fields?

[Suggy]

In my business rule, i have written like this

current.assigned_to =  "UserA"; -----> THIS WORKS

current.assignment_group = "GroupA"; ------> This DOES not work... WHY? (if I pass the sys_id, only then it works).

Why? both are reference fields. Then why the difference?

I am using a valid assignment group 🙂

You can try that scenario in your PDI 🙂

This response, 6 months after posting the question, not acknowledging the two answers which were immediately received???

My sincere apologies @Brad Bowman  

I missed it somehow. But since this scenario came up again and since there was no answer yet, I buzzed it again.
