Restricting Entry to Single Fields

To allow the user to process only single fields on the selection screen, you use the following syntax:

SELECT-OPTIONS seltab FOR f..... NO INTERVALS .....

As a result, the second input field does not appear on the selection screen. The user can only enter a single field comparison for the first row of the selection table. However, the user can call the Multiple Selection screen and enter range selections there.

Syntax Syntax

```
REPORT demo_sel_screen_select_no_int1.
```
```
DATA wa_spfli TYPE spfli.
```

SELECT-OPTIONS airline FOR wa_spfli-carrid NO INTERVALS.

End of the code.

The following standard selection screen appears:

The user can enter only a single field directly. However, the user can enter multiple selections by clicking the pushbutton on the right side of the screen.

If you use the NO-EXTENSION addition as follows:

Syntax Syntax

```
REPORT demo_sel_screen_select_no_int2.
```
```
DATA wa_spfli TYPE spfli.
```

SELECT-OPTIONS airline FOR wa_spfli-carrid NO INTERVALS

                                           NO-EXTENSION

End of the code.

the selection screen looks like this:

Now, the user can actually enter only a single field comparison.
