difference between modal screen and normal screen

[Former Member]

Hi everyone,

Now,I am developing a dypro. when I create a modal screen ,I found no difference between normal screen and modal screen.

eg. If I use the statement "call screen" , whatever which type of screen you use, the results look like the same. The same to the statement "call screen start at end at".

Hi Aaron,

There is no difference in the usage but it must be defined as a modal dialog box to comply

with the SAP System’s ergonomic standards.

Thanks

Hi Shilpa,

could you please explain "ergonomic standards" to me? Actually,I don't know what it is and I saw the sentence in SAP standard study material,too.

Hi,

If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT options.

Hi Neenu Jose,

I know that statement.But the question is the difference between normal and modal screen .

If you use the normal screen following the statement "call screen start at end at",the screen also will

not cover the previous screen.

Difference is:

If you define GUI status for normal screen, it appears on top of the screen.

But, if you define GUI status for dialog screen, it appears at bottom of the screen.

Hi

Screen type for modal dialog box

If you activate this attribute, the screen is used as a modal dialog box. In the program, you call the screen with

CALL SCREEN STARTING AT <top left>

ENDING AT <bottom right>.

Unlike normal pop-ups, a modal dialog box has its own pushbuttons and title. There is no menu bar and command field entries are not possible.

Normal screen type

If you activate this attribute, the screen is flagged as a normal screen. This is the default setting.

Alternatively, it may have the following special functions:

Subscreen

Modal dialog box

Selection screen

Class screen

In the Screen Painter, you can choose between normal, subscreen, and modal dialog box.

Selection screen and class screen attributes are assigned by the system.
