Check duplicates by custom field

[oraculo1]

Hi,
I've added a field named CIF in contact entity. The idea is that i need when one contact is created with, per example, CIF A00000000, if another user try to create another contacto with the same CIF, display an alert. I've seen it works when the name is equal, but it's a bit confused, because many people can have same name and surnames.

Thanks,

In Administration > Entity Manager > Contact > Edit > Duplicate check fields add your CIF field and you will have the desired functionality.

Hi victor,

I haven't last options. Is version 6.1

There was a lot of new features added since 6.1 which was released almost 4 years ago.

Yes, but when i try to update from 6.1, upgrades without problems since 7.3.4. From 7.3.4 to 7.4.x gives error 500 and a lo tof troubles

Each individual error requires analysis. Upgrade problems can be considered as a separate topic in a separate section. There is already a similar topic on the forum: https://forum.espocrm.com/forum/inst...ng-7-3-4-7-4-6.
