expected data from EHR

We are trying to understand that from our EHR are we supposed to get following data?
https://github.com/DBCG/connectathon/blob/master/fhir4/bundles/EXM105_FHIR4-8.1.000/EXM105_FHIR4-8.1.000-files/tests-numer-EXM105-FHIR4-bundle.json

If yes, how would EHR know what is numerator and denominator? Isn't that supposed to calculated on cqf-ruler?
