Purchasing Form From Orders

I’m trying to make a simple program form y Company as enclosed. But since I am new about Access I don’t know how I can solve my problems certainly so, I need your help about.

We are getting orders from the customers and we are buying from domestic market. I want to make easier to send purchasing orders to my suppliers. Normally, as you can see from the enclosed file sales person enter the order to the system (Orders TARIK KARABAY form). We want to use these data while preparing purchasing orders but we are buying some of the goods completely manufactured by our suppliers. We mean we buy the item and sell directly to the customer. This step is easy. At the same time we are buying parts from suppliers and assemble in our warehouse. I mean we produce them. This is the problem I have. One of the goods we buy is HTS3; we buy directly as HTS3 from the supplier or we buy HT3 from one supplier and R3 from another one and KD3 from a third one and we assemble HT3, R3 and KD3 in warehouse and we obtain HTS3.

While buying as HTS3 it is easy as the only thing is to add Supplier name to the system. But while it would be produced in house, the system has to prepare purchasing form for HT3, R3 and KD3.

Purchasing department will see the Order Form, they would prepare the purchasing easily without writing again.

I don’t know what kind of tables and forms I have to open to solve this problem.
