For some data sources that do not natively support MDX XLCubed can execute calculations on top of the source database.
Currently this is available for Fluence and Anaplan connection types.

Sample Calculations
These templates may be useful starting poitns for your own calculations. You should replace the Dimension, Hierarchy, Level and Measure names with your own.
todo
Item
Many functions return a set and you might want to choose a particular member from that set. A set is always a set of tuples (not members) so you might need to use the Item() function twice to get a member from the set.
For example in this calculation gets the fourth child of the current Date member. As Children returns a set we pick out the tuple, and then use Item(0) to get the only member in that tuple.
( [Measure].[Amount], [Date].CurrentMember.Children.Item(3).Item(0) )
IRR, MIRR, NPV
These functions accept a list of values as an argument, not a set of tuples and a value expression like Sum(), Avg() etc.
For these to work you should specify the member of measures to use so that the calculation does not reference itself.
This will evaulate the values for "My Set" in the context of the IRR measure which can not work.
IRR( MySet ) - wrong!
Instead reference the measure you want to calculate for and create a set with that member in.
IRR( { [Measures].[My Measure] } * MySet )
