I want manage a stocks in multiple warehouse. Here is my scenario..

Comp1[Shop A]- can make quotation/sales from Warehouse1 and Warehouse2

Comp2[Shop B]- can make quotation/sales from Warehouse1 and Warehouse2

(Many from Many relation)

(SHOP A is mapped to Warehouse A && SHOP B is mapped to Warehouse B)

Comp1 have 2 products such as Product A and B, They can purchase a products A & B by selecting warehouse A in PO screen.Hence the stocks are available in Warehouse A

llly Comp2 have 2 products such as Product C and D, They can purchase a product C & D by selecting warehouse B in PO screen.

Now, How i want to sell a Product C by select a warehouse A (SHOP A) in Sale order screen, then the stocks are going to negative. I want to stock should be less from Warehouse B.

Any other configuration need for solve this problem.... Kind give ur valuable suggestion..

Thanks in advance
