NEED SOME SOLUTIONS FOR-->> ALV Grid with Doubleclick Event & Hotspot???

Hi at all,

i have create an ALV Grid with an Doubleclick- and Hotspot Event for my column (ALTKN).

But there is one problem, because users should can be edit the column (ALTKN).

Is there an alternativ to Doubleclick or Hotspot???

For example get_focus & set_focus ???

MY LOGIC/ IDEA why i need Events?? (If anyone have other ideas please let me know)

Because user write some numbers in the column (ALTKN) and if they click on it, than it must be open a popup Window with an new Screen.

Thanks forward for helps.
