Question : Analysis services - MDX date calculation

Please advise if I'm in the wrong area to ask this.

I want to make a calculated member "age of employee" based on a dimension attribute
Employee.birth_date

Iimagine this would be something like

truncate( NOW() - Employee.birth_date )

IF MDX does date arithmetic !
Does it? and if so what syntax works?

Otherwise I have read a way ( media.wiley.com/product_data/excerpt/ 67/04714004/0471400467.pdf  dated June 2001)
to do this calling VBA!DateDiff

Answer : Analysis services - MDX date calculation

Right all depends on if there are any additional checks you want to perform.  Although, you can perform about the same functions in TSQL.  We already had VBA 'routines' that we were using from other systems though....
