Hello Everyone
When I Create purchase order I want to send that to supplier account.
I have added a route in portal setting but the page purchase order is missing in supplier account, What I want; when you click on Purchase Order link purchase-order page should be loaded in the same page like other portals.

I’m eagerly looking at your help
Thank you
