Hi Amy,
Thanks for your response.
I already had a look at this document. He has written the code using ON_DATA_CHECK event.
but my requirement is to have a list box in ALV.
So while clicking APPEND or INSERT , before the new line been added to ALV, i need to populate the value set.
So for this case we can't use ON_DATA _CHECK event.
Please reply back if you have got some idea.
Thanks&Regards,
Ashok
