How to see Original Purchase orders which are amended in NAV 2013

Rajiv304

Hello,

I got stuck as an auditor while performing Internal Audit of a company which is using NAV 2013. I want to check the invoice rates with the respective purchase orders made in the period when the invoice is received. But here, the original purchase orders are amended multiple times and I am only able to see the latest amended purchase order. Can someone help me out as to how can I get to see the purchase order before the amendment was done? My invoices are pertaining to the period before the amendment date and the purchase orders are amended towards rate change.

Waiting for the solution.

Thanks
Rajiv
