When you create new entry in Incoming Documents, after you approving it, you can add it only to Purchase Invoice or to Journal Line. This is pretty uncomfortable, because we have limitation. I like to use Purchase Orders for purchase process and post invoice from this document. In NAV standard, we cannot add Incoming Documents entry to Purchase Order and I have a problem.
You can improve it pretty easy. I wrote in my last post about adding new field on Purchase Invoice page. On the same way, you can add this Incoming Document Entry No. field on Purchase Order page.
You cannot add Purchase Order from Incoming Documents lines, but you can choose Incoming Documents from Purchase Order.
