DAX to return 1 if values in two columns are consecutive and the same

[BlueWhite111]

Hi Experts

i am trying to work out where the TASK ID Project ID are consective for two or more rows then return a value of one in a new column other wise 0. See below. not sure on how to do the DAX

Task ID	Project ID	Expected Result
1239498	1022	1
1239498	1022	1
1239498	1809	0
1239498	10566	0
1239446	1265	1
1239446	1265	1
1239446	19465	0

Hello @BlueWhite111 , I am not sure if you are looking for this. I have created three columns so that you can understand clearly. 

Output looks like this:

Three columns DAX will be like this:

Key Column = 'Table'[Task ID]&'Table'[Project ID]

Counting = CALCULATE(COUNT('Table'[Key Column]),ALLEXCEPT('Table','Table'[Key Column]))

Final Result = IF('Table'[Counting] = 2,1,0)

This is doable but not trivial. Also, you'll need an index or some other column (e.g., date) to tell if two rows are consecutive. Do you have that? What do you plan to do with this new column once you have it? There may be a simpler way to get to that result. If this is needed, does it need to be a DAX solution (or could it be done in your query with M)?

Hi ppm1, my end result is to filter out the values which do not meet the criteria. that;s it. I have an index column not a date column, M query if possible. other wish DAX so i can apply it as a filter at Page level
