ABAP_LDB - Interface Work Areas The following statement declares an interface work area intended for use with logical databases only:
NODES The statement NODES must be specified both in the database program of the logical database and in the executable program linked with the logical database. In the database program, NODES determines which data can be passed from the logical database. In the executable program, NODES determines the data received and also controls the creation of the selection screen of the logical database. If flat structures are used, the statement TABLES can also be used.
Latest notes:
If logical databases are no longer used, the statement NODES is obsolete.
If logical databases are still used, NODES should be used instead of TABLES. This specifies clearly that the interface is intended for logical databases. ABAP_HINT_END
