Duplicate validation issue in e-recruiting

Hello,

I have an issue with the duplicate validation in e-recruiting when creating an external candidate profile.

This is the scenario: when I enter the same name and last name of an already existing candidate but with a diferente email, the duplicate validation considers that there is a duplicate. But I want the validation to return a duplicate result, only if the 3 fields (name, last name and email) are equal as another register.
To make it easier to understand:

Candidate that already existes:

Name: A

Last Name: B

Email: Z

Candidate I'm trying to register:

Name: A

Last Name: B

Email: X

Result: the validation shows me a duplicate register since the name and last name are the same as the first candidate.

I have implemented the BADI HRRCF00_GET_DUPL_EXT_CAND to solve another part of this issue (don't know if this has caused this new issue).

Any ideas?

Thank you very much.
