Pairing two lists of names

[AbigailShaw]

Hi, 

I have a list of participants in a user group and i would like to pair them together based on different parameters eg different line of business, have they been matched before. 

Does anyone know how this may be achieved? 

Thanks :)

Please post sample input and output, in a table format or in an attached workflow.

For multiple matching scenarios, consider a "waterfall approach", shown in this sample workflow:

Can you provide an example of what you have and what you are trying to achieve? Based on what you are saying this seems like you would use a Join tool and whatever is in J output matches. But it would be helpful for me to have a visual.
