A lot of work has been done to improve the duplicate management tool and duplicate detection within RE NXT lately, however it now no longer detects as many duplicates as previously.
One example that I think might have been detected previously is that we have two constituents with the same surname, mobile number and email address. The differences between them is that one has a postal address and the other doesn't and one has the full first name and the other an abbreviated form of that name as first name.
The duplicates being detected now are indeed duplicates, so the tool is good at finding constituents that are very likely the same person but if possible, it would be great to have the ability to dial down the specificity?
