can have any name; the names are no longer strictly linked with the
Dictionary tables. Instead, a node can have any Dictionary or local
type. For example, a Dictionary structure can be used for multiple nodes
and a logical database can return a
complex data object "in one portion". New language element: NODES
.
ABAP_MODIFICATION_2 Adjustment to the
Function Builder : The created
program structure and the Logical Database Builder were adjusted
to the form known to the Function Builder.
ABAP_MODIFICATION_3 Free callability without change of roll area with

The restriction that logical databases can only be used with
SUBMIT is no longer valid. A logical database
therefore can be used by any program to collect data. You can also call
the same logical database more than once and nested calls of different
logical databases are also allowed.
