A measure to group by and concatenate

[kampyy]

ID	Sub ID	Sub Level
1	1	level 3
1	2	level 2
2	3	level 3
3	4	level 3
3	5	level 1
4	6	level 3
5	7	level 2
6	8	level 2

Looking for DAX Expression to - create a comma separate column of "Sub Level" group by "ID"

For EX.

ID	Sub ID	Sub Level	New Column
1	1	level 3	level 3, Level 2
1	2	level 2	level 3, Level 2
2	3	level 3	level 3
3	4	level 3	level 3, Level 1
3	5	level 1	level 3, Level 1
4	6	level 3	level 3
5	7	level 2	level 2
6	8	level 2	level 2

Thanks in Advance

Your column names are rather confusing.  How are the tables connected?

I have updated the question.

Not sure what you are trying to achieve.  Are you looking for a parent child hierarchy?

Here is the PATH output based on your sample data

Why is the Sub ID different from the Sub Level ?
