How to apply Measure in Dax Studio

[thangmcsa]

Hi All, 

I would like to add a rank column for virtual table created by Dax function, my code as below 

DEFINE
	MEASURE Sales[sale_amount] = sumx(Sales, Sales[Quantity] * Sales[Net Price])
	

	var temp = SUMMARIZECOLUMNS (
	    Customer[Country],
	    "Sales Amount1",Sales[sale_amount]
	
		)
EVALUATE
	ADDCOLUMNS(temp, "rankx",rankx(
	    		Customer[Country],
	    		Sales[sale_amount]
			)
		)

I got the error say "Table variable name 'temp' can not be used in the current context because a base table is expected" , this mean Rankx function can not work with virtual  table created by Dax code ?? 

Dataset used in the lab from this link Introducing RANKX in DAX

Hi,

Please try something like below.

DEFINE
    MEASURE Sales[sale_amount] =
        SUMX ( Sales, Sales[Qualtity] * Sales[Net Price] )
    VAR temp =
        SUMMARIZECOLUMNS ( Customer[Country], "Sales Amount1", Sales[sale_amount] )

EVALUATE
ADDCOLUMNS (
    temp,
    "rankx", RANKX ( VALUES ( Customer[Country] ), Sales[sale_amount] )
)

hi @Jihwan_Kim ,

The code provided work as well, however could you please help clarify why we can not use the code below ?

"rankx", RANKX ( VALUES ( temp[Country] ), temp[Sales Amount1] )
