ABAP_DESCRIPTION
The static next screen number of screen 100 is 100. The statement
TABLES adopts the components of the structure DEMO_CONN from the ABAP Dictionary. The structure DEMO_CONN has been especially created in the ABAP Dictionary for screens of the flight data model. Apart from the components of the database table
SPFLI , there is also a component MARK whose domain S_FLAG only defines the fixed values " " and "X" . On the screen, the Dictionary text for MARK has been overwritten with "Cancel"; for all other fields the Dictionary texts were taken. Some of the fields were deactivated in the Screen Painter. The user is allowed to enter values for the airline and the flight number. In this process, the user is automatically assisted by the field and the input help and the valid value check against check tables of the Dictionary. These checks are performed automatically before any dialog module is called in the ABAP program. It is neither possible for the user to enter an airline which is not defined in the check table SCARR , nor to enter any flight numbers not matching the airlines defined in
nor to enter values for MARK except " " and "X"
. You do not need to program these checks in the ABAP program. The module
user_command_0100 of the ABAP program reads additional values for the checked key from the database table SPFLI and sends them to the screen in the init_screen_100 event. The work area demo_conn
declared using the statement TABLES is used as the interface, while the actual data is processed in the data area wa_spfli . If the user fills the Cancel field with "X" , the program is quit.
