DAX - COUNTROWS - first occurrence of a value

Hi

I need help to create the 'RESULT TABLE' with a measure in DAX.

 

The 'RESULT TABLE' shows the first occurrence of the number '1' in each column

in the 'BASE TABLE' and returns the row number from the 'INDEX' column.

(The number '1' appears only one time in each row in the BASE TABLE).

 

Thanks for the help

Hi @dpbi

 

How about

 

Measure A =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[A] = 1 )


Measure B =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[B] = 1 )

Measure C =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[C] = 1 )

Hi @dpbi

 

How about

 

Measure A =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[A] = 1 )


Measure B =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[B] = 1 )

Measure C =
CALCULATE ( MIN ( BaseTable[Index] ), BaseTable[C] = 1 )

Thank you very much for your fast reply.

Your solution works. Thanks again.

 

Is their an option to make the calculation in one measure for all the columns?

(thats why i specified that  the number '1' appear only once in each row)

 

 

Hi @dpbi

 

Yes we can write ONE MEASURE

 

Follow these steps

 

Step #1 Unpivot the 3 Columns

Now You can write a single MEASURE

 

Measure =
CALCULATE (
    MIN ( BaseTable[Index] ),
    FILTER ( ALLEXCEPT ( BaseTable, BaseTable[Attribute] ), BaseTable[Value] = 1 )
)

 

 

Thank you very much again.

Fast replies, working solutions. 

Well appreciated.

Thanks
