VBA: compare combinations of two cells

[Nelson78]

Hello everybody.

I have the following job.

In sheet2 there are a variable number of association column A/B (in this case 5).

The goal is matching these 5 associations with the associations already present in sheet1:
- if already present, do nothing
- if not present, insert a row below the related item and report the unprecedented association.

The outcome has to be as you can see in the image

It works very well.

The problem is that in real life, as usual happens, we have to deal with something unexpected.

In this case, some of the 76 associations are not univocal: i need to report on the receiving sheet just one of them, to avoid duplicates.

Yes, the easiest way is removing duplicates in the receiving sheet (it is no possible to perform it in the source).
But I wondered if it is viable to work directly on the combination array/dictionary.
