Interface work areas
Interface work areas are created only once for each program group and shared by the main program and its additional loaded programs. The assignment of programs to program groups can be dependent on user actions, field contents, and switches, which means that interface work areas are extremely error-prone, with respect to their functions and to their maintainability. The only interface work areas that can still be used for special purposes are table work areas declared using TABLES . The following declarations are completely obsolete:

DATA - COMMON PART

TABLES *

The statement NODES (once required for interface work areas between logical databases and executable programs) is also no longer required if you no longer work with logical databases.
