In classic alv I remember an option to expand total lines (show detail lines) and collapse total lines (hide detail lines) by clicking an icon that looked like a printer icon:
Now I discovered that this option is not available in OO alv - not out of the box anyway. I have searched for options in the field catalog, the layout structure, the styles option, but so far I only found something that seems to be the opposite of what i want.
The is_layout-no_totexp seems to be a flag to set if I want to prevent that total lines is expandable, but I has no influence if I set this flag or not.
How can I have this functionality in OO ALV?
