Change/Display in ALV Grid

Hello All,

I am using FM 'REUSE_ALV_GRID_DISPLAY'. It is required that when the user presses a button on the screen, that a few fields toggle from display mode to changed mode. I know that setting the input and edit fields to X for the field catalog table will allow a user to change the table but only on the initial display of the grid. Does anyone know how I toggle between the change and display mode of the ALV grid? Thanks for your help in advance.

John
