OLAP Cube and percentile values

[LukeL]

Hi all.

I have a simple question for you 

We would need to create a percentile measure in an olap cube. As far as know, the measure is not available as a predefined aggregation, but...is there a way to obtain it, maybe via mdx or via information map? The problem is that this kind of measures, as a nunique, would rely on all the original dataset, and cannot be preaggregate...

I have tried by making a calculated mesure by making a key dimension for each row, and calculating the measure as

pctl5(90, SetToList({[KeyDimension].CurrentMember.Children},[Measures].[MeasureToUse])),

where measure to use use a mean aggregate function (but going to keyDimension I would have the mean of every single value, so the value itself).

but the response is:

Insufficient memory - in the "CHILDREN" function

Has anyone any feasible solution?

Thanks! 🙂

Hi LukeL,

You might want to open a track with Technical Support for that “insufficient memory” message. There may be some options or a different syntax that might work for this exercise.

Best,

Anna
