Expression as a dimension

[bobbydave]

=if([Data Category]<>'Adjusted', null(), avg(ACT_GBP.Materiality))

Any ideas how I would write the above as a dimension?

[sunny_talwar]

You will need some kind of Aggr function here. What exactly are your Averaging ACT_GBP.Materiality over (which dimension)?

=If([Data Category]<>'Adjusted', null(), Aggr(avg(ACT_GBP.Materiality), DimensionName))

or may be this

=If([Data Category] = 'Adjusted', Aggr(avg(ACT_GBP.Materiality), DimensionName))

[rubenmarin1 · Accepted solution]

So, you want the average of ACT_GBP.Materialty where [Data Category]='Adjusted'?

It can be: Avg({<[Data Category]={'Adjusted'}>} ACT_GBP.Materiality)

Just to advise, you can create expressions without dimension if you only want a bung of predefined calculations.
