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)

If this post helps, then please consider accepting it as the solution to help other members find it more quickly. Thank You!!

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
