We updated the Requisition window to more closely model the Order. Changes include:
Added UOM, QtyOrdered, etc... fields to allow for specifying the UOM on the Requisition Line.
Added Charge field to Requisition Line.
Added reference fields to Requisition header and line (Project, Campaign, User Defined, etc...)
Update the Create PO from Requisition process accordingly.
I believe this changes needs to be in the core to make the Requisition process more of an iDempiere 1st class citizen.
I created the ticket to allow Deepak to engage the core team to support this effort.
