Thanks for getting back to me, no I hadn't at the time I posted. After reviewing the link, it appears that the decision tables will have to be manually built out if I understand correctly.
The user interface has 10 selection fields, and each selection field has multiple selections a user can select. The user can select up to 5 options in each selection field. So building out all of the different options this way would take quite a bit of time because with this example we're speaking of +50k scenarios.
I'd like ARD to build out all of the possible combinations the user can encounter automatically. In short, we give ARD the field names and static selection options and ARD outputs all of the possible combinations or scenarios a user could select.
