Hi, our old Admin setup an Purchase Order Basic Approval Workflow and I am trying to understand it. On the image, I can't seem to figure out where the Field "PO Procurement Approver" is coming from. I don't know if it is obvious, but I am not familiar with workflows as much as I should be.

So this is joining to the Subsidiary record. So it is looking at the current User's Subsidiary, then there must be a custom field on your Subsidiary record called PO Procurement Approver, that is sourcing that value

Thank you, I kept looking at the employee record for the field!
