Hi Rich,
Thanks for your reply.
I have attached code here because Raymond asked me to give much more information, As per my understand i sent the code. Sorry if i misunderstood.
I have used two methods for event TOP-OF-PAGE in a class and i am calling them through single instance.
And to display data in two grids i am using 2 different instances of type CL_GUI_ALV_GRID, and by using these objects i am calling LIST_PROCESSING_EVENTS.
Thanks,
R V Narayana
