Hi Sreekanth,

It would be better if you elaborate your issue. As of my understanding you rather need to capture an event or recognize that some input is given in input field.

For this you can define the fields in CHAIN and ENDCHAIN. Like as below.

CHAIN.
  FIELD: <f₁>, <f ₂>,...
  MODULE <mod₁>.

ENDCHAIN.

You can also refer to the link below

Input Checks in Dialog Modules (SAP Library - ABAP Programming (BC-ABA))

And regarding your screen shots,

'Get From Directory' is an option to assign the properties to an input field as that are defined in Data dictionary referring through Data Element.

regards,

Vijay

Your solution is works only in the case of when my PAI get invoked.

But in my case i am just inputted a letter in an input field, at the same time the screen got refreshed

and the button become active.

Hi Sreekanth,

I have doubt, lets say Input Field length is 5. By the time I enter 1 char/num if system takes it as input, then how to take complete input or whether it has to read 5 times?

What is the length of input field??

Hi Sreekanth,

        If ur input input filed is not initail , then use loop at scrren , and make the field group active = 0.

ex :

if Input_filed is not initial.

loop at screen

if screen-group1 = '001'.   " give the screen group for the button which want to be active or in-active

screen-active = 0.

modify-screen.

endif.

endloop.

endif.

Any doubts ???

Hi vijay,

           Here i did't press any button or menu on screen and not enter Enter key through keyboard.

And my doubt is how the screen got refreshed?

Code behind the button get active and deactivate is might be that you have provided.

But how this code got invoked while i just typing in the input field.

Hi srikanth,

I doubt whether the screen painter is developed using abap. I guess Screen Painter is a 3rd party windows application integrated into SAP, ie. Just as same way Adobe LiveCylce designer is integrated for creating Adobe forms.
