Requisition approvals based on Purchasing categories SOLUTION

Content

In case anyone else has been trying and failing at setting up approvals with a purchasing category condition, the correct syntax is unintuitive:

Turns out that it has to be "equals" instead of "is" for this one.

Example: Procurement Category Hierarchy Level 1 EQUALS "Technology"

NOT:   Procurement Category Hierarchy Level 1 IS "Technology"

I hope this saves someone else the time and frustration that I expended!
