Item based Approvals in Requisitions

Summary:

Looking for ways to implement Approvals based on Item Attributes (Item level DFFs) .

Content (required):

We have a Approval workflow , wherein there approvals are based on custom categories (created Specifically for approvals - lets call it approval category).These categories no way are related to the Item Categories . i.e., Items belonging to one Item category can be associated to many of these Approval Category.

They have 3 different types of these "Approval Categories" - based on which approval should be triggered.

For now I have suggested them to use the Item Hazard Class and UNSPC number to capture these categories (As they are a Banking customer and they currently are not using those Fields) and to setup approvals based on these.
