Hi all
i had programing a simple tree with alv, check URL
[http://bildupload.sro.at/p/350813.html]
on the left side, you see database. Now, when you click ones of db, it should show the db with data fields in ALV. The first click work, but continue doens't work. Why?
thx

Hi,
You clear (REFRESH I_TAB...) in event generated by theclick on left side?
May be you are appending at the end of internal table...
