Hai
Check the following Code
REPORT z_alv_grid_ctrl_refresh_2.
ALV Grid Control *
This report reads and displays data from table MARA, using *
the Method set_table_for_first_display of CL_GUI_ALV_GRID *
Button 'NEXT_PAGE' : displays the next N records *
Button 'PREV_PAGE' : displays the previous N records *
Button 'FIRST_PAGE' : displays the first page *
Button 'LAST_PAGE' : displays the last page *
When the buttons Sort up, sort down, Filter, Delete Filter are *
pressed, N record are still displayed *
Steps : *
- Create the report Z_ALV_GRID_CTRL_REFRESH_2 *
- Create the Dynpro 0100 (size 27x120) *
- Add OKCODE (type OK) in the element list *
- Modify the flow logic of dynpro 0100 : *
* PROCESS BEFORE OUTPUT. *
MODULE pbo_0100. *
* PROCESS AFTER INPUT. *
MODULE user_command_0100. *
- Create a status named 'MAIN' *
with the buttons : REFRESH BACK EXIT *
and the buttons : FIRST_PAGE PREV_PAGE NEXT_PAGE LAST_PAGE *
