hello! I am trying to join 2 data sets but there are no matches, in which case shouldn't the "left" output both before and after the join be the same data?
I am seeing different outputs and am not sure why
If there is no match between 2 tables, then left output would be same as left input anchor and right output would be same as right input anchor with no data in Join.
Could you send screenshot of your data and mapping?
