PO and Invoice Amount - OTBI

Summary

Need to show PO and Invoice Amount in a report

Content

Hello - I have a requirement to show the Invoice Amount and PO Approved amount in the same report. I can see the Invoice Amount field in Procurement Spend subject area and 'PO' related amounts in Procurement Purchasing Real time subject areas.

1. Is there a measure in Spend subject area that refers to PO Approved Amount? If not how do I bring that into my report?

2. Which Amount field in Procurement Purchasing subject area is close to the PO Approved Amount? I see Billed Amount, Purchasing Order Distribution Amount etc.
