Problem Faced In ALV Grid Row Selection

Hi Experts,

I am displaying the output in ALV grid format.

Now i am using cl_gui_alv_grid->Get_selected_ROWS to get the row index selected by User and on clicking a button it will take us to another screen which will hold the values of the selected row.

<b>Problem Faced</b>: But when we again go back to the first screen and select another row and click this button the selected row’s index remains initial, that value is not getting captured.

please help me if a am missing something.
