Getting data back from ALV grid

Question

This looks like a topic discussed before but i still need some clearifications. I display an internal table in ALV grid, in editable format. user changes the data and presses A BUTTON. On doing that I need to re-capture the changes made in a internal table.
I have used method "check_changed_data' but it doesnt seem to work. It keeps appending data in the internal table if the user changes it multiple times. please suggest me some ideas on how to go about it.
Thanks.
