I really hope you can help me
I need to compare datatable 2 (new version) with datatable 1 (old version).
The column names are the same but the contents can be different. There is no ID or key, because each key figure can be occure more than once.
However, the combination of the key figures in each column are unique.
It should be checked in every row if the combination of Column1+Col2+Col3+Col4 from dt2 is already included in dt1. If not, the new combination from dt2 should be shown up as the result in dt3.
Thanks in advance,
