Magento 2 Multistore features will be visible when multiple locations are enabled in your Accumula account. All Multistore settings are found on the Order tab at Apps > Magento > Orders. Each feature can be controlled on a per location basis.
Order Routing and Store Priority
Accumula uses the Store Priority List to determine where to route orders to first. You set the Store Priority, as desired, by dragging each row to the desired position.
Accumula will look first in the top store then work down the list. If no location has inventory for all line items, the order will be routed to the top store.
When Order Splitting is on, Accumula will try to fulfill the order from a single location first by looking first in the top store then work down the list. If no single location can fulfill all line items and quantities, the order will be split between the first locations that have inventory for each item.
If a location does not have the quantity needed to fulfill the order, quantities for the line item will also be split and assigned to locations to ensure that the full quantity is fulfilled.
These features are controlled by the master switches on the Orders tab. Each feature can be enabled and disabled on a location by location basis.Orders will be fulfilled in the order of the stores. Stores can be reordered by grabbing the left hand side of each store row and dragging it.
