Line (multiple) or Header vendors. Do you have any suggestion / experience / defect to highlight when talking about this topic? What I would like to understand is if you can define Netsuite as "adopting an equivalent behavior" regardless of the choice. Since we have an integration for what concern PO we could create 1 order each vendor OR 1 order for all the lines but in this moment I'm not able to understand if there is any limitation / bad behavior in using vendor in the line of the PO. (Client's preferred choice)

I think you are asking if you can have one PO with multiple venders... that answer is no. You can have a multiple lines on a PO but they must all be to the same vendor. You can have a Sales order with multiple lines and choose the vendor that the items will be ordered from but that will still generate a PO for per vendor.

Ah ok, so the PO is always for a single vendor while in requisitions you can choose multiple vendors then are trasformed in multiple PO, right? Don't know why but I was almost sure about a vendor in line available in the past.

You are correct, A requisition can/will generate multiple PO's. PO's vendor specific however. Are you working on job costing or is this just for inventory?

This is just because when this company order a "product" the product it's made by different components ordered from different authors. So let's say they sell subscriptions to access all western movies and they order the movie which is composed from the music, the video, the special effects etc etc. Since this is really a small business (2%) of the HQ business they don't have projects /manufacturing features which could handle this scenario in a more elegant way.
