Ship From Org id is null in oe_order_lines_all?

 Hi All,

           Untill now I never did any sales order or saw any sales order without ship from org id. But is it possible? As I can see the data both dropship and normal order lines with ship from org id is null. Wether oracle use the validation organization id by default? If so it will keep track of that organization in the column in lines all table? In some cases I see the ship from org id is populated for drop ship orderlines, but not all the cases. Any reason for this behaviour?

Thanks and Regards,

Hatakesh.
