a new column in modeling with aggregation

Hi All, 

 

I have this table: 

ID  StartDate  EndDate  Price
123  1/1/21  1/31/21 
123  2/1/21  2/28/21  10
123  3/1/21  3/31/21  10
123  4/1/21  4/30/21  10
123  5/1/21  5/16/21 
12345  1/1/21  1/31/21 
12345  2/1/21  2/28/21 
12345  3/1/21  3/31/21  20
12345  4/1/21  4/30/21  20
12345  5/1/21  5/31/21  20
12345  6/1/21  6/30/21  20
123456789  1/1/21  1/31/21 
123456789  2/1/21  2/14/21 

 

I need a table with a new column (CountofNum) : 

 

- If the price is not empty it appears for the first time in each ID card so Table[CountofNum] = '1' 
- If the price is not empty and it appears a second or more time in each ID then Table[CountofNum] = '0'
- else null 

 

for example:

 

ID  StartDate  EndDate  Price  CountofNum
123  1/1/21  1/31/21  
123  2/1/21  2/28/21  10  1
123  3/1/21  3/31/21  10  0
123  4/1/21  4/30/21  10  0
123  5/1/21  5/16/21  
12345  1/1/21  1/31/21  
12345  2/1/21  2/28/21  
12345  3/1/21  3/31/21  20  1
12345  4/1/21  4/30/21  20  0
12345  5/1/21  5/31/21  20  0
12345  6/1/21  6/30/21  20  0
123456789  1/1/21  1/31/21  
123456789  2/1/21  2/14/21  

 

Thanks All!

    That would be like this.

    CountofNum = 
VAR _Start =
    CALCULATE (
        MIN ( 'Table'[StartDate] ),
        ALLEXCEPT ( 'Table', 'Table'[ID] )
    )
RETURN
    IF (
        'Table'[Price] = BLANK (),
        BLANK (),
        IF ( 'Table'[StartDate] = _Start, 1, 0 )
    )

    Try this as a new calculated column.

    CountofNum =
VAR _Start =
    CALCULATE (
        MIN ( 'Table'[StartDate] ),
        ALLEXCEPT ( 'Table', 'Table'[ID] ),
        'Table'[Price] <> BLANK ()
    )
RETURN
    IF (
        'Table'[Price] = BLANK (),
        BLANK (),
        IF ( 'Table'[StartDate] = _Start, 1, 0 )
    )

      and if I want to do a column that shows me just if the 'price' is not null and the 'CountofNum' is 1 and the id appears the first time like this :

       

      ID  StartDate  EndDate  Price  CountofNum
      123  1/1/21  1/31/21  20  1
      123  2/1/21  2/28/21  10  0
      123  3/1/21  3/31/21  10  0
      123  4/1/21  4/30/21  10  0
      123  5/1/21  5/16/21  
      12345  1/1/21  1/31/21  
      12345  2/1/21  2/28/21  
      12345  3/1/21  3/31/21  20  0
      12345  4/1/21  4/30/21  20  0
      12345  5/1/21  5/31/21  20  0
      12345  6/1/21  6/30/21  20  0
      123456789  1/1/21  1/31/21  50  1
      123456789  2/1/21  2/14/21  50  0
