Doubts on Different Issues

I have a several Doubts from one of client. I am sharing to have a concept for Doing Excersises.

Q.1. One Raw material is used in Two differnet Manufacturing units of same company maintaning two different ware houses.

A is one Ware house

B is second Ware house

How can the SAP B1 do the same for Both Ware houses but item is same.

Q.2 Purchase orders to be raised in Head Office but we need to have Different series by Unit wise.

Q.3 When any Item purchased we will have different quotations from differnt vendors. Now how can we show the same in SAP B1 at the time of Preparing Purchase order to select least quoted Price.
