Count the presence of unique values in Item column based on Week

[datadog_ab]

Below is the source coloumn and goal is to count 1 if the unique items for ID exceeds 2 over a week. Here in Week1 The unique items were 2 so it will be considered 0 and in week2 the unique items exceeded 2 and will be counted as 1. 

ID	Item	Week
100	Shoe	Week1
100	T-Shirt	Week1
100	T-Shirt	Week1
100	T-Shirt	Week1
100	Shoe	Week2
100	T-Shirt	Week2
100	Cap	Week2
100	Shoe	Week2
100	Belt	Week2

So here unique items for ID exceeded in Week 2 So the result will be below

ID               Result

100                1

Create a measure as follows:

Result = 
COUNTROWS(
    FILTER(
        ADDCOLUMNS(
            SUMMARIZE( Table01 , Table01[Week] ),
            "@count" , CALCULATE( DISTINCTCOUNT( Table01[Item] ) )
        ),
        [@count] > 2
    )
)

That did the trick. Kudos @Fowmy
