ABAP_SOURCE_CODE ABAP_EXEC
ABAP_DESCRIPTION This example program consists of six parts, each illustrating one of the screen_options additions of the statement PARAMETERS. Each example corresponds to a block on the selection screen 100.
Part 1: If the cursor is not on the input field, a symbol appears in the input field of the parameter p which tells the user that an entry in this field is required and that the program cannot continue if no entry is made in this field.
Part 2: The three parameters p1, p2, and p3 have the same length of 10 but are displayed with a different length on the selection screen. The user can nevertheless enter 10 characters in each field.
Part 3: Two checkboxes are displayed on the left side of the selection screen with the selection text appearing to the right of the boxes. The checkbox b has the default value 'X'. The elements of the modification groups sc1 and sc2 (see part 6) can be shown and hidden together with the two checkboxes. The display is switched immediately since the event AT SELECTION-SCREEN is triggered if one of the checkboxes is chosen. The function code is not needed. Instead, the content of a or b is evaluated at PBO.
Part 4: The radio buttons r1, r2, and r3 form the group rad1; s1, s2, and s3 constitute the group rad2. Only r2 and s3 are selected on the selection screen, all others are not selected.
Part 5: The parameter p_carrid is displayed with a length of 20 and filled with the label 'Lufthansa'. The user can select another airline; in this case, the three-character airline ID is assigned to the parameter. Assigning the function code onli which is assigned to the Execute function in the GUI status of the selection screen triggers first the event AT SELECTION-SCREEN and then START-OF-SELECTION.
Part 6: The parameters test1 and test3 are assigned to the group sc1; test2 and test4 to the group sc2. At the event AT SELECTION-SCREEN OUTPUT, the field INTENSIFIED of the internal table screen is set to 1 or 0, depending on the contents of the field group1. On the selection screen, the lines for test1 and test3 are highlighted whereas those for test2 and test4 are not.
