PO Processing Statistics
I wanted to see if the community could weigh in on how folks are tracking and reporting PO statistics in terms of Buyer processing time, etc.
Our base model is a query that subtracts Requisition Approval Date from PO Approval Date to calculate "Day Turns", broken down by Buyer and Item Category, to track the time it takes our buyers to take Reqs through sourcing and on to dispatch.
The main issues that skew our stats are Change Orders. We usually process change orders by copying a new requistion (for the modification requests) to an existing PO. This messes up our calculations since a given PO could now appear multiple times and have wildly misrepresented "Day Turns" since might be calculating a year-old Req against a recently re-approved PO.
