Hi, I'm new to this so please forgive the question: I have the following expression using set analysis =Only({1<S_START_DATE = {'$(=MonthEnd(Max(Addmonths(S_START_DATE,-1))))'}>} STATUS_VALIDATED) and I have a filter called BP_Business_Partner that I would like to exclude from the calculation, I've seen options for sum, however cannot get this to work on the '=Only()' statement.
