Greyed out fields not triggering ON CHAIN-REQUEST

[former_member1292715]

Hi Guys,

I have a text box on a screen with input not possible (greyed box). But the value of that text box can be changed by clicking a button in the same screen. Now, I wrote a code to give a pop-up upon exiting the screen, if the user didn't save the data. I got this fuctionality using keyword ON CHAIN-REQUEST.

But it is getting triggered, if the user changes the value on the white text box. But I changed the value of greyed text box using the button on the screen. For that, ON CHAIN-REQUEST is not getting triggered. Please help me out to solve this problem.

PROCESS AFTER INPUT.

Hi,

Try using the following

  CHAIN.
    FIELD: zmm_spa_item-uptby_tc, " Greyed text box
           zmm_spa_item-rmrk1_tc,
           zmm_spa_item-rmrk2_tc,
           zmm_spa_item-rmrk3_tc,
           zmm_spa_item-rmrk4_tc.
    MODULE get_changed_data ON CHAIN-INPUT. "CHAIN-REQUEST.
  ENDCHAIN.

Or take a flag in the User Command of button where you are making this field Grey
if that flag is = 'X' or Check sy-datar

Then call the Function Module POP UP

Hello Ram,

Thanks for your input. But I have 10 screen with many buttons and based on the button clicked, I change the value of the grey text box. So I want some generic thing like ON CHAIN-REQUEST. I can even compare the old value from PBO and new value from PAI, if they are not same, I can give a pop-up. But I am just wondering, is there anyother way to do this.

thanks

Yasin.
