The HIDE statement is one of the fundamental statements for interactive reporting. You use the HIDE technique when creating a basic list. It defines the information that can be passed to subsequent detail lists.

TABLES: spfli, sbook.
DATA: num TYPE i,
      dat TYPE d.

  num = 0.

  num = num + 1.

        num = 0.
        CLEAR sbook-bookid.

        WRITE: 'Customer type   :', sbook-custtype,
             / 'Smoker          :', sbook-smoker,

      ENDIF.
  ENDCASE.
At the event START-OF-SELECTION, the system sets the status FLIGHT for the basic list. In status FLIGHT, function code SELE (text SELECT) is assigned to function key F2 and to a pushbutton. So the event AT USER-COMMAND is triggered if the user double-clicks, presses F2, or chooses the pushbutton SELECT.
The three fields spfli-carrid, spfli-connid, and num are stored in the HIDE area while creating the basic list. After selecting a line, the system displays the detail list defined in the AT USER-COMMAND event for function code SELE. In the AT USER-COMMAND event, the system refills all fields of the selected line that were stored in the HIDE area. You use num to check whether the user selected a line from the actual list. The detail list has status BOOKING, where F2 is assigned to function code INFO (text: Booking Information). The detail list presents data that the program selected using the HIDE fields of the basic list. For each list line displayed, the system stores additional information in the HIDE area.
If the user selects a line of the detail list, the system displays the stored information in a dialog box with the status WIND. For the WIND status, the default values for the status type Dialog box have been adopted with the list status adjustment. The program uses sbook-bookid to check whether the user selected a valid line.
The program itself sets all page headers and the title bar of the dialog box.
