Count Distinct Dates between 2 dates, by ID

[Anonymous]

Hi peeps

I have this data

Date	ID	Value
1/1/2018	8088	100
1/1/2018	8088	100
1/1/2018	8088	100
2/1/2018	8088	0
3/1/2018	8088	300
3/1/2018	9999	100
10/1/2018	9999	0
17/1/2018	9999	200
20/1/2018	9999	400

How can I calculate

a) distinct count of dates, within start and end date, by ID? 

b) Sum of Value where value is > 0.

ID	Start Date	End Date	Distinct Count of Dates (value > 0)	Sum of Value
8088	1/1/2018	2/2/2018	2	600
9999	3/1/2018	20/1/2018	3	700

Hi @Anonymous,

Based on my understanding, the "StartDate" and "EndDate" are known values in a second table (suppose it's 'Table_2'), right?

That case, please create a calculated table to get your desired output.

Table_3 =
VAR temp =
    FILTER (
        CROSSJOIN (
            Table_1,
            SELECTCOLUMNS (
                Table_2,
                "ID2", Table_2[ID],
                "StartDate", Table_2[Start Date],
                "EndDate", Table_2[End Date]
            )
        ),
        [ID] = [ID2]
            && [Date] >= [StartDate]
            && [Date] <= [EndDate]
    )
RETURN
    SUMMARIZE (
        temp,
        [ID],
        "StartDate", FIRSTNONBLANK ( Table_2[Start Date], 1 ),
        "EndDate", FIRSTNONBLANK ( Table_2[End Date], 1 ),
        "Distinct Count of Dates(value > 0)", CALCULATE ( DISTINCTCOUNT ( Table_1[Date] ), Table_1[Value] > 0 ),
        "Sum of Value", SUM ( Table_1[Value] )
    )

Tried but I got this error message

"DAX comparison operations do not support comparing values of type Text with values of type Date. Consider using the VALUE or FORMAT function to convert one of the values."

here's the pbix file

Hi @Anonymous,

The date column in Table1 and enddate column in Table2 are set to "Text" in your .pbix file. Please change their data type to "Date".

Best regards,

You can get this data in the Edit Query itself my doing some grouping:- 

1. Filter the data with 0 in the Edit Query

2. Group you data and in the Operation do the distinct count.

Result : 

Thanks

Did I answer your question?
If yes, Mark my post as a solution!

Thanks.

I think this will do what you want

Measure =
CALCULATE ( DISTINCTCOUNT ( Table1[Date] ), Table1[Value] > 0 )

It returned 6 for all rows. 

It should be Count of Distinct Dates within Start Date and End Date, by ID.
