1.2 Screen Child

This topic provides an overview on Screen Child creation.

Screen Child can be derived from a parent screen or a child screen. The Screen Child uses the packages for maintenance functions from the parent itself, only screen-level modifications can be done in a Screen Child.

It should be noted that Screen Child are not exactly the child of child screens (second level inheritance). It can be the child of a parent or a child screen. The difference between a Child and aScreen Child is that only screen level changes can be done in a Screen Child. Business logic will remain the same as its parent. In the child screen business logic can also be enhanced for the child function ID.
