Nested aggregation


I need to nest aggregation functions for my project demands. I need to nest concat inside sum funcion .

I use aggr function to enable the nesting of aggregation functions.

Here is my code. It is one of expressions in pivot table, where Agent.FullName is a dimension.

=sum(if(ComplexTargets.Areas = aggr(concat( distinct AreasForAgentByDate.AreaCode,'*'),Agent.FullName),ComplexTargets.Target))

concat( distinct AreasForAgentByDate.AreaCode,'*') - returns me the right value

The equality : ComplexTargets.Areas = aggr(concat( distinct AreasForAgentByDate.AreaCode,'*'),Agent.FullName) is works when it is not in outside aggregation function and i checked that there is matching values.

AreasForAgentByDate.AreaCode is connected to the data cloud, whereas ComplexTargets.Areas (ComplexTargets table) is not connected - stand alone table.

I get 0 for all agents, like there is no matching values for anybody.

Do you have any idea what can be the problem ?

Thanks a lot.
