Filter based on values from another table
So, I am really new to power BI. This sounds really simple but I'm clueless how to make it work.
I have two tables, which are linked with a many to many relationship. I want to be able to only show numbers in table A that does not exist in table B.
If we take my example from below i want to be able to show (count: 3) and (numbers: 2, 4 and 6)
Table A
| number | xx | xxx |
| 1 | xx | xxx |
| 2 | xx | xxx |
| 3 | xx | xxx |
| 4 | xx | xxx |
| 5 | xx | xxx |
| 6 | xx | xx |
Table B:
| number | yy | yyy |
| 1 | yy | yyy |
| 3 | yy | yyy |
| 5 | yy | yyy |
