Sourcing Rules and allocation of inventory on Sales Order Lines

 Hi,

I have a UK customer that can obtain stock from a UK warehouse or a GE warehouse.

If I place a manual order or an order via iStore and there is no stock in the UK warehouse, I expect the sourcing rule (which has been setup for the UK location to have the UK warehouse as rank 1 and the German warehouse as rank 2) to kick in and realise there is no stock in the UK and automatically assign the sales order line to the GE warehouse.

This is not happening. Even if we have zero stock, the lines will always be assigned to the UK warehouse and not the GE warehouse - why is this?
