A change status represents a particular processing state for a routing object ( for example a header or operation).

When you create a routing, each of its objects has initially only one change status, valid over the entire validity period of the routing.

If you never change routings using change numbers, your routings always have only one change status.

As soon as you change a routing object using a change number, the change status of the object is split into two statuses. The split is dated to the Valid-from date of the change number. Every further change with change number results in a further change status. The only exception is if the routing object was previously changed with a change number and had the same Valid-from date. In this case a further change status is not created.
