How do you map the position to the role? What is the relationship between position and role, one role for one position text or multiple roles can be mapped to multiple positions?
How did you implement the automatic assignment in the first place?
And with the role you mean business role in IdM, not an ABAP-role?
What kind of volumes are you talking about?
You can implement the automatic assignment with context based provisioning or as simple as assigning the role to the user where "position text = role name".
All of that depends on the complexity of your data/relationship between the position and role.
