Error in Calculated Dimension ISSUE

[#1]

i facing the problem with Error in Calculated Dimension when i use the formula with :

Wu + (Yu *Median(uETFintercept)) . Any one can tell me what's wrong with my formula?

[#2]

Can u share a sample file

Median() is an aggregation function. If you use an aggregation function in your calculated dimension, you need to have an Aggr() function around it.

But I don't understand what you are trying to do...

ya i think this is my prob....thk for fast reply....and i try it 1st......thk~~~~

[#5]

but hw should i write on expression? Arg(Wu+Wv*Median(uETFintercept)) like this?? i try this but the software cant calculate for me......

[#6]

when u use aggr() function, u should use like Aggr((Wu+Wv*Median(uETFintercept)),Dimension)

without dimension you cant use aggr() function.

Specify the dimension
