Data References in the Shared Objects Memory

shared objects memory can also be created with direct reference
to data elements and table types of ABAP Dictionary using the addition
AREA HANDLE of the statement CREATE DATA.

Methods PROPAGATE_AREA and PROPAGATE_INSTANCE Replaced
The methods PROPAGATE_AREA and PROPAGATE_INSTANCE of an
area class for transactional

and INVALIDATE_INSTANCE can be used for areas of this type with the Application Server area binding.
