Conditionally Select A Table give me error message

[jimmyhua]

I created two tables one is for All divisions/ entire organization and one for divisions when one division is selected.  I have a variable called DivisionFilter using HASONEVALUE to detect if a division is selected.  if nothing is selected, I want to use the All division table to do a Top 10, otherwise I will use the division table to show divisional Top 10. 

When I use if statement below, I got a error message saying "The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value".  

How do I fix it.  Thanks.

IF(
DivisionFilter,
FILTER(RankedDivision, [RankByBL] <= 10), // Top 10 within each division if filtered
TOPN(10, RankedAll, [Backlog], DESC) // Top 10 for the entire organization if not filtered
)

hello @jimmyhua 

that happens because both FILTER() and TOPN() will give table (multiple value) as return value where your result needs to be a scalar (one value).

i believe FILTER() and TOPN() need another function to return as scalar.

here is a simple examples in form of measure.

Filter =
IF(
    ISFILTERED('Table'[Column2]),
    CALCULATE(
        MAX('Table'[Column1]),
        FILTER(
            'Table',
            'Table'[Index]>=1&&'Table'[Index]<=10
        )
    ),
    SELECTEDVALUE('Table'[Column1])
)

- unselect (return all value)

- selected (return value with index 1 to 10)

Hope this will help.
Thank you.

Hi,

I am not sure if I understood your question correctly, but please check the below picture and the attached pbix file.

expected result measure: =
VAR _t =
    ADDCOLUMNS (
        SUMMARIZE (
            ALLSELECTED ( billing_fact ),
            division_dimension[division],
            billing_fact[billing]
        ),
        "@amount", CALCULATE ( SUM ( billing_fact[amount] ) )
    )
RETURN
    CALCULATE (
        SUM ( billing_fact[amount] ),
        KEEPFILTERS ( TOPN ( 10, _t, [@amount], DESC ) )
    )

Hello @jimmyhua,

Can you please try this approach:

Top10Table = 
IF(
    HASONEVALUE(DivisionTable[Division]), 
    FILTER(RankedDivision, [RankByBL] <= 10), // Top 10 for selected division
    TOPN(10, RankedAll, [Backlog], DESC) // Top 10 for the entire organization
)
