Benefits Dependent Eligibility - Determination Formula

Hi,

We're creating a Dependent Eligibility profile for Male Children under 18 years of age. Since the system doesn't provide Gender Criteria in the dependent eligibility profile, we're using a Determination Formula.

If we attach the Determination Formula in the profile, how will the Eligibility Profile be evaluated:

1. Will it be overriding the Age Eligibility Criteria that I have defined using Derived Factor and I'll have to add logic directly in the Formula to calculate age as well?
2. Will it be using both the logic in the Determination Formula AND the Eligibility Criteria that I have defined?

Any suggestions will be helpful.
