Hi Anonymous,

 

Can you show up the expected result based on your data in your first post, please? I can't find out the logic here because I don't know what it should be for "LSDM", including XXXX, HHHH, SSSS. 

"They should be unique across entire daterange", why the XXXX is counted every year?

The PowerPivot in Excel and the Power BI are almost the same. You can use it directly. 

Can you modify my demo to show up what the result should be?

 

Best Regards,
Dale

Hi Dale ( v-jiascu-msft ),

 

Apologies if my sample data was not clear or correct as i randomly created it. Here is a clearer example. See the Characteristic Values that i have colored using Conditional Formatting. Each appears only once during entire Daterange. These i would call "Emerging" Characteristics. The rest that are repeating every year, i would call "Trending" Characteristics.

 

Attaching the Sample Data for your inspection which has Pivots conditional formatted on Characteristic Values column.

Sample Data.xlsx

 

Also if you can please refer my Notes section for the remaining questions and guide me how they can be answered using Pivot & DAX.

 

Thanks.

    Give this a shot

     

    DistinctCount =
IF (
    CALCULATE (
        COUNT ( tblData[CHAR VALUE] ),
        ALL ( tblData[Item Appearance Date (Year) 1], tblData[CHAR DESCRIPTION] )
    )
        = COUNT ( tblData[CHAR VALUE] ),
    1
)

      If you want the Grand Total as well

       

      You will have to add this Additional measure as well

       

      Please see your file attached

       

      DistinctCount with Totals =
IF (
    HASONEFILTER ( tblData[Item Appearance Date (Year) 1] ),
    [DistinctCount],
    SUMX (
        SUMMARIZE (
            tblData,
            [Item Appearance Date (Year) 1],
            [CHAR DESCRIPTION],
            [CHAR VALUE]
        ),
        [DistinctCount]
    )
)

        Zubair_Muhammad getting Errors on both formulae:

         

        DISTINCTCOUNT:
Semantic error: The function COUNT takes an argument that evaluates to numbers or dates and cannot work with Values of type strings.

DISTINCT COUNT WITH TOTALS:
Semantic error: Dependency error in the measure.

        What could be wrong here? is it the format of the dates?
