Open SQL "IN" operator for HANA SQLScript

Hi,

Is there a equivalence in HANA SQLScript for the Open SQL operator "IN"?

I'm aware of the regular "IN" operator for SQL, where you can specify a list like (1000, 1001, 1002...), but, for instance, I'm interested in finding out a equivalence for the matnr IN r_matnr sentence in a query, where you an get a list of materials from the MARA table, if specified any in the range structure, or the whole table if not. I get a different structures types error, when using a range type from my AMDP importing parameters in the select sentence.

Thanks in advance.
