using procurement data for commitment reporting

Summary:

Looking for a way to report commitment data using procurement data

Content (please ensure you mask any confidential information):

We currently report purchase commitments (how much we have outstanding to pay) using the purchasing subject unbilled amount field. This works ok but it is net of VAT so would like to know how other institutions report commitments as best practise? I have had requests to show the full amount outstanding to be paid including VAT but the subject area does not have this that I can find? Thanks
