Hi Ahmad,

These functions do not exist in MDX, please see the MDX function documentation here: https://docs.intersystems.com/iris20221/csp/docbook/Doc.View.cls?KEY=D2R...

You likely want to use the %OR function: https://docs.intersystems.com/iris20221/csp/docbook/DocBook.UI.Page.cls?...

Using %OR would allow you to reference multiple members, for example:
Expression="%OR({[Demographics].[H10].[Citizenship].&[USA],[Demographics].[H10].[Citizenship].&[U.S.A],[Demographics].[H10].[Citizenship].&[US]})"  

Hi Virat,

Here is a good resource for getting started with InterSystems IRIS BI (DeepSee):

If you are interested in creating dashboards and exploring your data, IRIS BI is a good choice.

If you are interested in traditional reporting, you may want to consider InterSystems Reports:

Thanks, this works. I did have to click the "+" icon and add a new namespace to the Explorer, since adding the namespace from InterSystems Server Manager did not pull it into the ObjectScript Explorer. This is kind of an unusual case since I don't necessarily have a project/workspace for the generated class I want to view. If I already had one, then I wouldn't need to use the namespace explorer.
