Selected Value Blank

[Anonymous]

Hi Guys, So I have two tables :
a. Name Master table
b.Data table

And a visual which contains all the names from the Name Master table

Name in the "Data table" can be in 6 different columns. The Name Master table is related to all 6 Columns
So my aim is to calculate an expression but for that I need to check in which of the 6 columns that name is present and then filter that "Data table" according in which column it has been found. Below is the Dax which I tried to write for returning the selected name but it is giving me blank at some places.

Selected Name= SELECTEDVALUE( Name_Master_List[Name])

Please help me guys I cant think anymore.

Thank you, @sturlaws!  This helped me solve a similar issue. 

I had created a numeric measure using SUM() and a filter for [field] = SELECTEDVALUES([other field]). 

Individual rows were returning the expected SUM() in my matrix visualization (since [other field] would have a single value within a single row's row context). 

However, the Total row in the matrix was blank.   I figured out this was due to the fact that the row context for the Total row would have multiple values for [other field] and, therefore, SELECTEDVALUE([other field]) in that row context would return null and, therefore, the SUM() was null.

After reading your post, I was able to update my formula to filter by IN VALUES([other field] and now my SUM(), SUMX() actually, is returning the correct, summed values for the Total row.

FilteredSum =
/* Create a one-column table of Table1 key values for the current row context.
 * (This method, using VALUES() instead of SELECTEDVALUE() to get the value for the 
 * current row/row context, is necessary in order to SUM() the measure when 
 * there could be multiple "selected values" within the "Total" row context.) */
VAR t1KeyValues = VALUES('Table1'[T1_KEY])
RETURN
    SUMX(
        FILTER(
            'Table2', 
            'Table2'[T2_KEY] IN t1KeyValues
        ), 
        [T2_VALUE_TO_SUM]
    )

@sturlawsCan we connect somewhere it will be easy to explain you the scenario

Hi @Anonymous ,

here is one way of achieving what you want to do:

Measure =
VAR _names =
    VALUES ( Master[name] )
VAR _c1 =
    CALCULATE ( SUM ( data[sales] ); FILTER ( data; data[Column1] IN _names ) )
VAR _c2 =
    CALCULATE ( SUM ( data[sales] ); FILTER ( data; data[Column2] IN _names ) )
VAR _c3 =
    CALCULATE ( SUM ( data[sales] ); FILTER ( data; data[Column3] IN _names ) )
VAR _c4 =
    CALCULATE ( SUM ( data[sales] ); FILTER ( data; data[Column4] IN _names ) )
RETURN
    _c1 + _c2 + _c3 + _c4

although with only 4 columns, but you get the picture. For this to work, you need to remove all the connections between Master and Data.

Cheers,
Sturla
