SLA : What are options to show purchase order Number when viewing Invoice information?

Hi Gurus,

When we are drilling down from GL to SLA for an AP Invoice, the SLA information shows accounting information and Invoice information too but does not show PO information

Whether its matched to PO or not? If yes, PO number, i will like to have this information in SLA, is it possible and how? Not planning to populate all the invoice information, we will like only one or two extra Invoice related information in SLA, which will save us lot of time avoiding the need view transaction form.

Please let me know your thoughts.

Cheers
