I've never worked with it. However going back a yr+, i spoke to Gary at Sage re: Active Planner for MAS 90/200. He said it does work with MAS 90/200 and I believe he said it works with ODBC imports rather than direct integration like with MAS 500 - even though the Active Planner website showed that it didn't work with MAS 90/200. And I think the pricing for MAS 500 also applied to MAS 90/200.
