Sale Order Subcontracting & Vendor wise stock

Dear Gurus,

     I have one doubt we are doing sale order subcontracting transfer posting by 311 E to vendor. so is it really need to create vendor wise storage locations to track the stock at vendor end,  as we have no. of vendors for subcontracting and storage location is part of organization structure.

so is it advisable to go like that ? or please suggest me any other way to track the stock at vendor end sale order wise.

Thanks & regards,

Akshay
