Re: Partner unicity

Hi,

Thanks Alexis for bringing up the topic.

Uniqueness is a difficult one and relies on the user ability to separate false unique partners. VAT uniqueness should be implemented (on active partners) but other constraints looks "impossible".

Warnings are important to help but IMO fuzzy display of existing partner names while typing name/email/phone is a very good tool to improve data quality.

Hi Alexis, 

this is indeed a hard nut to crack. Just a quick idea. As you said no one measure can provide
a very convincing solution for that problem alone i guess, but what i often thought of 
in that regard was a kind of fuzzy matching (on strings for instance) over more than one dimension?
But that i technically and performance-wise for sure harder to implement

Best Frederik
