ALV search results display refreshing

Hi there,

I plan to use an ALV grid in order to display different search results. My problem is that after running a search and displaying the results using the method 'SET_TABLE_FOR_FIRST_DISPLAY' , and then running the search again with the same parameters, I get duplicate entries displayed. Can somebody please advise?

Thank you in advance.

PS. I am not shure whether my question is the same as that one raised in Tim van Steenbergen's 'How to Refresh an ALV-gr..PLAY'...
