A delivery changes its status when it is processed further. The status is assigned manually and it is not necessary to run through every status.
Open the delivery from the Supplier account by clicking on Purchasing > Deliveries.
Alternatively, find the delivery through Purchasing > Search either under Purchasing or Purchase deliveries.
Right-click on the delivery in the side navigation to assign a new Status .
As soon as the status is changed, a new segment is created that contains the older segment and can be changed independently of it. Note: Only the latest segment can be edited, all other segments are blocked.
