diferent products point to same stock level

[Janekx]

Hello, i look for solution of my idea. PS1,6 with ASM 

I like to point two or more products to same stock level in ASM, because products are same but with small diferent setup what we do for customer. so 

Products have own product listing but have as well own stock level in ASM 

product ID 1 name X

product ID 2 name Y 

in PS_stock is 

ID_stock 1, id product 1, reference X, pquantity 1, uquantity 1, price xxx

ID_stock 2, id product 2, reference Y, pquantity 1, uquantity 1, price xxx

so each product have own line in ps_stock

As i told the products are same so we must keep same product in two lines and if one is sold out we must one decrease and one increase becuase one sold stop be available and can be easily taken from other line. So idea is to point this products to one stock line, it will decrease by orders and increase by restockin and all products will be available until really stock is not empty. 

 

Any idea how to help me ? Thnaks
