ALV heading: dynamic layout name and description

Hi,

I am using FM 'REUSE_ALV_GRID_DISPLAY' in my report. The heading contains the layout name and description. Once executed the user may decide to change the layout to another saved layout. How can I get the heading to reflect the new layout name and text i.e. what field name will I be using and how will I use it.

Help is much apprecieted,

Thanks,

Leanne
