ALV: Right Button Click and Context Menu

[Former Member]

Hi Experts,

I have to implement an ALV which should act on a right button click and show a context menu.

Is this possible? I found only events for "on_double_click" or "on_link_click" and is it possible to show a context menu?

Thanks in advanced.

Best regards,

Markus

Hello Markus

The relevant events are:

CONTEXT_MENU_REQUEST

USER_COMMAND

Have a look at my sample report ZUS_SDN_ALV_CONTEXT_MENU_1.
