Drop Shipment question

Hi,

Using ebs 11.5.10.

Trying to setup Drop shipment process using :

- standard POs

- purchase price would need to be same as selling price available into sales price list (want to avoid having to setup price at item master)

- supplier would need to be derived from sourcing rule / ASL

Goal for this is to be able to create sales orders, then automatically create drop shipment POs without having to fill in supplier and price.

Already setup Drop shipment using Blanket Purchase Agreement releases, but this is not satisfactory for business change reason.

Has anyone already been setting this up ? any help welcome.
