Hi Petra,
I don't know if any of the POPUP_* function modules do a checkbox list. I think most do radio buttons, but worth a look. If not, it's not a big job to write your own.
Regards WF patterns, there are two easy ways I can see:
- Multi-choice fork with the un-chosen ones disabled by a condition.
- Dynamic parallel processing with dynamic tasks.
The second will work nicely if each process follows the same pattern.
Regards,
Mike
