Hi Meriem,
Since you dont have the vendor handy, while creating the shopping cart you can leave the SUGGESTED VENDOR field as blank. You will be able to order the shopping cart without assigning vendor. Once the cart is approved, it will go to carry out sourcing (Purchaser Worklist) since no vendor assigned to the shopping cart. Then purchaser (Buyer) will setup the vendor in the system and using that newly created vendor, s/he can create the PO for that shopping cart.
