you have to Call the method REFRESH_TABLE_DISPLAY method of the Corresponding Gird in your case it is second grid . and you will be able to see the values.

Hi,

This generally happens when we donot referesh or clear the internal table or workarea.

So refresh the data in internal table before used .

example :

CLEAR: g_wa_outtab.
 REFRESH: g_t_outtab.

hope this helps.

thanx,

dhanashri.

Hello Lakshmi

You may have a look at my sample report ZUS_SDN_TWO_ALV_GRIDS_2SCR.

Double-click on a customer on the first screen and its sales areas are displayed on the second screen.

Go back and repeat this using another customer.
