Calculated dimension in aggr

[#1]

Hello,

is it possible to have aggr() do roll up over a calculated dimension? Something like:

=aggr(sum(Sales), Year(Date))

It looks like aggr breaks the moment I put any expression as dimension. For example,

this works: aggr(sum(Sales), Date)

and this doesn't: aggr(sum(Sales), if(1=1,Date))

Any help would be appreciated!

I dont think that would work as the aggr statement will not have something solid to query the data model with.

Does the calculated dimension have to be calculated on the front-end or could it be pushed back to the data model?

Hi.

There is a note about calculated dimensions in help:

There is a special function for advanced aggregations:

aggr ([ distinct | nodistinct ]
[{set_expression}]expression {, dimension})

Returns a set of values of expression calculated
over dimensions. The result can be
compared to the expression column of a 'local chart', evaluated in the context
where the aggr function resides. Each dimension must be a single field. It cannot be an expression (calculated dimension).

... That is, the field Year must be created in the script.  After that, this will work:

aggr(sum(Sales), Year)
