Modify ALV GRID contents on button click

[Former Member]

Hi,

In my ALV grid display, am creating a new button in the toolbar. Once I click on the button the values displayed should change. More precisely if the values are 100, 200, 300 after clicking on the button it should show as 100%, 200%, 300%.

Need sample code please.

Thanks

Hi,

I think you can do it by trying to use this code

Hi Ramya,

Just concatenate the value with '%'.

Look into the sample code attached.
