Module pool check box - dynamic enable/disable screen fields possible ?

[Former Member]

Hi Experts,

I have one module pool report. There are two parts of the screen for header and item details.

Now the requirement is if one field in the header part is ticked then dynamically all other fields(both header and item) on the screen should be disabled for input.

And if the user removes the tick mark then all the fields should be dynamically enabled for input.

I know in an executable program this can be done using at selection screen output event. but how to achieve this on screen programming ??

Thanks,

Hi

You can use loop at screen in the PBO of the module pool .

You ca check the value of the checkbox and then maintain the input/output characteristics of the fields.

Hi

create a module in PBO

PROCESS BEFOR OUTPUT.

MODULE screen.

______________________

MODULE screen output.

IF CHECK = 'X'.

     loop at screen

          <write the logic for disabling like in report.>

     endloop.    

endif.

ENDMODULE.

Hi Laxman,

Thanks for your reply.

Is your logic going to work after the screen is loaded??

Because my requirement is that if the user unchecks the tick mark then the screen fields should be enabled for input.

hi

yeah it will work. and also you need to write disbaling logic when user click checkbox

and enabling logic if user not click check box.

Hi Laxman,

I have written the code and it works but I have to press ENTER every time I check or uncheck the checkbox then only the fields are enabled/disabled.

So how to make it work without pressing the Enter button ?

Hi Laxman,

Below is my screen flow logic. I have written the code you have suggested in the MODULE deactive_screen.

Hi

check once when you click on checkbox whether the control goes to debugging or not.

Hi,

It only goes to debugging when I check/uncheck and press ENTER button.

Otherwise it doesn't make any changes to the screen fields.

I think PBO wont get triggered without pressing ENTER button.

Is there any other way to do this ?

Thanks,

Vishal .

Hi Vishal,

Go through following standard report you will get idea.

DEMO_DYNPRO_MODIFY_SCREEN

Hi,

Use this logic, set group for fields,

If check = 'X'.

   LOOP AT SCREEN.

IF screen-group1 = 'G1'.

    screen-input = 0.

MODIFY SCREEN.

ENDIF.

   ENDLOOP.

ELSE.

   LOOP AT SCREEN.

   IF screen-group1 = 'G1'.

   SCREEN-INPUT = 1.

   MODIFY SCREEN.

   ENDIF.

ENDLOOP.

endif.

Hi Vishal,

First you have to set a function code for check box, refer snap.

Now on-wards when ever you click on check box the events PAI and then PBO will get triggered.

Write code for disable fields in PBO.

if g_cbox = 'X' .

loop at screen.

endloop.

endif.
