I have a factory that makes custom products according to client order. I also have a couple of stores selling these products, however, unless we have been requested a delivery, the clients are requested to go and get the final product at the factory.

By default, OpenERP use the store location as the delivery address. How can I change this according to my need?

I am using the sale_multi_shop module. Each shop is related to a particular warehouse. It is only when the client request a product for fabrication the client should go to the factory for the pickup.
