    bhatsuchi,

     

    You may refer to the measures below.

    Measure =
COUNTROWS (
    FILTER (
        VALUES ( Table1[Id] ),
        CALCULATE ( COUNT ( Table1[Email] ) > DISTINCTCOUNT ( Table1[Email] ) )
    )
)

    Measure 2 =
COUNTROWS (
    FILTER (
        VALUES ( Table1[Id] ),
        CALCULATE ( DISTINCTCOUNT ( Table1[Email] ) > 1 )
    )
)

Mariusz Thank you for the quick reply. Table is created and relation also build between two columns. Between new table [id_column] and direct query table [id_column]. As per your instruction I have created another mesure also that counts rows for direct query table. But i didn't understand how to achive the result i wanted like i posted in my question.

Here is the result I am getting after used values from dynamic table created.
please find the sample PowerBi file (GoogleDrive). I have created this powerbi file using exact sample data i have provided in my quesion and applied your solution on that. If you can work on that file and send me back. That would be really helpful.

    Hi Anonymous 

     

    Sorry, missed CALCULATE()

     

    Table = 
ADDCOLUMNS(
    DISTINCT( DirectQuery[ID_ColumnID_001]), 
    "Repeated time", FORMAT( CALCULATE( COUNTROWS( DirectQuery ) ), "" ) & " Times"
)

      Hi Anonymous 

       

      and - 1 to start @ 0 Times.

       

      Table = 
ADDCOLUMNS(
    DISTINCT( DirectQuery[ID_ColumnID_001] ), 
    "Repeated time", FORMAT( CALCULATE( COUNTROWS( DirectQuery ) ) -1, "" )  & " Times"
)

      Mariusz Great! I think one thing missing is. I am not seeing anything that is 

      0 Times repeated = 

      Is our dynamic table showing data like

      ID_001 as  = 1 time repeated?

      and

      ID_001

      ID_001

      as =  2 times repeated?

       

      After we got this. I would like to know if we can group repeated tiems like this example:

      0 times repeated       |    50 ids 
1-3 times repeated     |    20 ids
4-5 times repeated     |    10 ids
>5 times repated       |     8 ids

      Mariusz  Thank you so much for your help on this.

        Hi Anonymous 

         

         

        Please see the adjusted code.

        Table = 
SELECTCOLUMNS( 
    ADDCOLUMNS(
        DISTINCT( DirectQuery[ID_ColumnID_001] ), 
        "no", CALCULATE( COUNTROWS( DirectQuery ) ) -1
    ),
    "ID_ColumnID_001", [ID_ColumnID_001],
    "Repeated time no", [no],
    "Repeated time", 
        SWITCH(
            TRUE(),
            [no] = 0, "0",
            [no] IN{ 1, 2, 3 }, "1-3",
            [no] IN{ 4, 5 }, "4-5",
            "> 5"
        ) & " times reported"
)
