From a list view or grid view, it's possible for the user to drill down and see details. In that list view or detail view, the B2B ordering system can present a hierarchical structure if an order is split or if the order has different fulfillment. This could occur if an order is going to a single location with a single payment, but the timeline may be split out because a portion of the order was filled immediately and then another portion is filled later based on inventory and lead time.
Therefore, it is possible to show not just the overall order, but a drill down so that the user can see which parts of the order have been completed and which parts of the order is still pending. The user can then click into any part of an order so, if an order to split out, they can click into a split portion of the order or the primary overall master order. You could think of it as an order that is split into a master primary order and then suborders that are grouped into the primary order.
All of these have detail views. The detail view is where many of the specific functionality and advanced capabilities live. This can be accessed from the user dashboard, or it could also be from a status email or some other interaction such as a chat with the vendor where the vendor is referencing a specific order.
