example1:

I have a product called product1 . I want to keep some alias names for this product like p1,p2,p3. If we make SO/PO on p1 or p2 or p3, product1 inventory should effect with alias products also.

I have only 10 quantity of product: product1. In inventory it should show like p1 quantity:10, p2 quantity:10, p3 quantity:10, product1 quantity:10. If 5 quantity sales order make on p2(or any one of these 4 products) and delivered these, the inventory should show like  p1 quantity:5, p2 quantity:5, p3 quantity:5, product1 quantity:5

How can i proceed for this.

example2:
I have more than three names for one product. These three should show in the product list irrespective of location, user, partner i.e who ever the partner would be and wherever the location would be and who ever the user would be. My product would be one, But i want to show that with different names. Whenever the transaction would be made with one of these three names. Product inventory should make effect. Does it possible in openerp version 7.0?.
