Processing a service call - first select the item, then the warehouse / filter on specific warehouses
When a technician is processing a service call he first must select the warehouse and afterwards the item.
It would be better if he can first select the item and then the warehouse, where the list of warehouses is limited to those warehouses in which the item is available.
If not possible, then the technician should be able to filter on some warehouses. Now the only options are 1 warehouse or all warehouses. It should be possible to filter on some warehouses
