Hello JJ,

 

Thanks for your quick response and solution

 

I am using directquery models and i think thats the reason i am getting below error while using below logic.

 

Function 'SUMX' is not allowed as part of calculated column DAX expressions on DirectQuery models.

 

Any ideas on this.

 

Thanks,

Sai
