MDO Query: using IN predicate as parameter?

Hi experts,

afaik, MDO queries support OPEN SQL. In Open SQL, there is the IN predicate, that is SELECT...WHERE x IN (...).

Is there a way of using this as filter for a select MDO Query?

If so, what format do I ahve to pass the "Filter" array?

I tried to pass a list to a query and refered to it as [MODEL] = [Param.2] in filter section...without success.

I have a workaround in place but still wonder if there is a more efficient way?

Thanks for your feedback!
