Mixed packs are a unique type of product in Breww, and they function a little differently from other products in Breww when it comes to assigning stock to a delivery. The key difference is that you cannot manually assign mixed packs to an order; they are always auto-assigned for you. For this reason, you will always see this tag next to your mixed packs when assigning stock to an order. If you expand the product under the Stock required header in Breww, you will also see the following message:
This message does not necessarily mean that you have enough stock to fulfil the order or that no additional steps are required, but this will depend upon your stock levels and auto assign product settings in Breww, which can be found in Settings → Delivery settings → Auto assign products. Mixed packs will always be auto assigned to your deliveries, but whether this is possible is determined at dispatch and is calculated as follows:
In principle so long as you have stock available, and allow breww to auto assemble and disassemble small pack on auto assignment, you shouldn’t need to do anything and Breww will take care of the stock assignment for you.
