SKU’s currently are only one way “Transfer-From”. Many companies have Offsite Overflow warehouses used for bulk storage that does not fit in the main location. The companies manually transfer inventory to and from these locations and planning does not view the inventory as available and typically suggests messages to order more (the is not nettable / non-nettable functionality in BC).

If a “Transfer-To” location was added to a SKU, it would allow planning to suggest transfer orders from the Offsite warehouse to the main warehouse when inventory was available Offsite. This would be beneficial as offsite inventory would be used before recommending new message to order more inventory. Transfer messages would show in planning until the demand was greater than the total inventory of the main and offsite locations combined, then new purchases would be recommended.

Here is an example:
The company receive a full truckload of product to the main location. There is only room for 10 of the 40 pallets on the truck so the other 30 pallets are transferred to the offsite warehouse manually.
Sales orders come in and ship from the main warehouse and deplete the 10 pallets of material until at some point additional stock is needed in the main warehouse.
Current functionality would not see the inventory in the offsite warehouse and messages would generate in planning to order more inventory. The buyer needs to be aware there is inventory offsite and to delete the messages in planning and create transfer orders.
IF there was a “Transfer-to” setup on the SKU for the item, instead of creating purchase messages, the planning would create transfer orders for the material as needed from the offsite warehouse to the main warehouse until the demand was greater than the total inventory in the main and offsite warehouse.
