call_message_screen screen size change

[sriram_ramesh]

Hi all, I'm using FM call_message_screen to display messages for scanner solution development. but the screen size(width) is too big in scanner that we have to scroll to press "OK" button. Is there anyway i can reduce the screen size?

changing "i_line_size" just changes the number of characters per line but not the screen size.

thanks in advance.

Hi

I think it is not possible.

Try to use an other ABAP Pop-Up solution.

Check some here.

For example, C14Z_MESSAGES_SHOW_AS_POPUP

Hope that helps

There is a parameter in the function module interface that refers to the screen used. In the corresponding function group you can check the screen sizes.

For instance, standard screen 0999 (8/40) is used, but screen 2999 (15/20) can be used instead. Just make sure the screen elements are the same of course.

If this considers an RF transaction, I usually use FM L_USER_DATA_GET to keep track of what user uses which screen size.

Hello Saber,

Thanks,

But we are not supposed to use pop-up screen in a scanner solution.

Thanks patrcik.

I used screen number 2999 which is the size i need. It works.

But when i click on "OK", it says

"Logical screen

number could not be

found".

Can you help me out?

Yes, this is an RF-ID based transaction.

Try debugging it. The PAI of the screen may try to return (or refer) to a screen-number that does not exist in your report.

[sriram_ramesh]

I get your point. But it works if i use screen '0999' in the FM.

And i debugged, there seems to be some issue with screen '2999' when used in that FM.

[sriram_ramesh]

there is a selection in standard program.

SELECT SINGLE * FROM T3130E INTO I_T3130E WHERE

                    MODPL = LV_MODPL AND

                    LSCRN = PREV_SCREEN.

lv_modpl is SAPLLMOB.

in the table, only screen number with 0999 exists. not 2999

I think that is some customizing table. Check this thread:

Thanks Patrick.

Even if data exists there, the program is throwing me out of the tcode if screen '2999' is used.

[Patrick_vN]

You keep getting the same error? Or has the adding a record in T3120E resulted in another error?

[sriram_ramesh]

It resulted in someother error.

Thanks for your replies patrick, I've designed another custom screen to display the messages.

Hello krishnamurthy,

Thanks,

But we are not supposed to use pop-up screen in a scanner solution.
