My database has 3 companies: A, B and C.

B and C are daughters companies of A.

B and C have their own warehouses and stock, while A no warehouse or stock because it is an office.

I set for my products are not of any company.

I shipping products from the location B to the location C. And here comes the problem.

Those products shipping from location B to location C, are recorded as if the owner of that product remained B.

It causes if you want to make a sale from the warehouse C, the system says it has no availability product.

The system does indicate that the product is in the location C but it "belongs" to B.

Then only I can get that product warehouse C if the user changes from company to B.

What happens to me is that in the same warehouse can have the same product belonging to two different companies.

How I can do to eliminate this feature that makes the stock movements have their own?
