SAP Screen Personas 2.0: No possibility to open DropDown selction variant button with Script?

Hello everybody,

is there any possibility to open the selection variant-button in ME21N (Document Overwiev On) with a script?

If I make a record, this step will translate into the command "right click". But this step will NOT work later in a Script-Button!!!

I tried push, click, etc. but nothing work.

With GoogleChrome the recording will also crash silverlight.

So I cannot handle it with scripting. Is there any SAP Note or Idea how can I handle this issue with scripting in SAP Screen Personas 2.0?

Thanks for help

Benjamin
