Hi again,
Thanks for the answer, but I've used the Candidate Selection for the mode input data versus master table (I mean, the mode with two separated sources) and I don't really know how to set it to say "just take one record from the input data in the comparisson against the master table".
When more than one records from the input data are similar, they are grouped in the same group and I get groups with several records where I get more than one from the input data (and,obviously, more than one from the master table, which is correct).
So what I get with the Candidate Selection is just a priorization (by sorting) to get the "reference" record from the input data in the comparisson but I can't stop the matching transformation from taking more input data records in the same group.
By the way, I'm using break group keys so that records with certain fields different are not trying to be matched with each other (I don't know if that could be the problem).
In conclusion, I would like to know how to say in the Candidate Selection or any other configuration parameter that I want just one record from the input data (and one or more from the master table) in every matching group (and also, I would like to not get groups of just master records with no input data records in them because that is useless).
Thanks again and Merry Christmas,
José
