Optimal way to dynamically change approver in Workflow Studio?

[MBarrott]

I have a Catalog Item which allows the user to select which department should be approving the request. 

In Workflow Studio I'm developing the flow which, based on the selection from the end-user, will determine who gets sent the approval email. i.e. user selects dept_a then approver should be approver_a, if they select dept_b then it's approver_b.

I can think of a couple ways to achieve this (Set Flow Vars and if/else logic) but curious if there is a more optimal action or method to achieve the same result.

Hello @MBarrott 

If your department field options are limited, then you can go with if else logic else you can explore Decision table.

Hi @Viraj Hudlikar 

I'm actually looking into Decision Tables now but unless I can add values from the flow's data pills then it may be difficult. The department field isn't from the cmn_department table directly.
