Ideas on how to build a PO form or report

Dear all,

When I am validating a quote for a customer, quote items can contains different product from different supplier.

The problem I have is that I do not know how to handle my product correctly. The reason for that is that a unique product can be purchase from different customers and can have different cost prices.

Does it means I need to have 2 different product which in fact have the same excecpt the price and supplier reference ?

How to handle this first ?

Next when my first questtion is solved, when I am processing the Order from a Win quote, I need to be able to generate a PO from the Order. The goal of the PO is to be able to send a repoert paper of product list that needs to be Order to a given supplier.

How to acchieve this ? if I were using SQL directly I would create a store procs and then associated it a a combo box in my report selection, but using CRM online it require to use FetchXML so how can I approach this in order to generate a report from my Order which will have as parameter the Supplier reference. Then only product from that supplier will be fetch from products grid..

Any idea how to do ?

regards
