Another question regarding these ALV grids.
I am using the function REUSE_ALV_GRID_DISPLAY_LVC to display a grid as popup window in a standard CRM transaction (called from an action).
The user is able to select checkboxes in this grid but I want to add "select all/none" buttons to be able to check all checkboxes for all records in one shot.
I have tried several things with the I_CALLBACK_PF_STATUS_SET parameter but I can't really get it to work. Do you have any ideas?
