hi Thulasiraman 

SUMMARIZE returns a table, and, in most cases, a table can't be used as a scalar value directly. So comes the warning.

You need either make some calculation based on that table or use the code to create a new table.

Hi FreemanZ 

 

Thanks for the explanation.  Can I use this dax in TOPN function?

    hi Thulasiraman Yes, as you see in MahyarTF 's code, SUMMARIZE is every commonly used to build intermediate virtual tables for furthe calculation, like TOPN, ADDCOLUMNS, FILTER. Any function taking table expression as argument is good to nest upon SUMMARIZE.

      Hi FreemanZ 

       

      I nested in topn function but it shows error.  I posted the screenshot above.

        Hi FreemanZ and MahyarTF 

         

        In continuation of above, after referring some material I have created the following for TopN which is working fine:

         

        Top3 DC =
        VAr ranking = VALUES('Itemwise DC All'[Dye Item])
        Return
        CALCULATE([Total cost], TOPN( 3, ALL('Itemwise DC All'[Dye Item]), [Total cost]), ranking)
         
        There is no creation of virtual table through SUMMARIZE but the above dax gives correct result so far for 3 of my tables which I tried.
         
        I request you to kindly validate the above dax if it is correct and applicable in all conditions.
         
        Once again thanking you very much for your patient help.
