If an object is added to a role or workset as a delta link, this means:
The object in the structure hierarchy of a role or workset (target object) is linked with the source object by a link. This means that both objects (the source and the target objects in the role) do not exist independently of each other. The dependency is always in the direction source object -> target object.
The objects in the structure hierarchy of a role or workset (target objects) can be changed within the role. For example, entries can be deleted or added in linked worksets. Properties of iViews and pages can be changed. These changes have no effect on the source object.
If the source object to which the target object links is changed, these changes are copied by the target object. For example, if you change the properties of an iView, the changed properties are transferred to all the iViews that were derived from this iView.
The main advantage of Delta link concept is that objects can be reused or changed without changing the original or source object. You can make changes to delta link objects (target objects), such as deleting or adding entries in role hierarchies or changing property values for iViews and pages, without having to change the source object. It is not affected at all.
With the delta link concept you can protect your own objects and the content objects shipped by SAP and other vendors against modifications
