Unable user input ready column depending on selection.

Hi All,

I am using IP and WAD.

I have two user input ready columns of keyfigures.

With first column having some value that can be changed by user if he wish to do so,now I want to unable the second column editing only if user is making any changes to first column.

Or else second column should be hiden/disabled.

And this needs to be for individual row of records.. Whichever record changed only that row second column needs to be activated.

How to achive this functionality?

Regards,

Shweta
