This Measure Resource can be processed for both Generating the necessary dataset and also calculating the Indicator

For generating the dataset necesary for the Indicator, Load the above resource into the Hapi Fhir and invoke the collect-data FHIR Operation with GET request like below .
GET: [Fhir_base_url]/Measure/TX-PVLS/$collect-data?periodStart=<date>&periodEnd=<date>

For Generating a Measure report , Load the above resource into the Hapi Fhir and invoke the evaluate-measure FHIR Operation with GET request like below .
GET: [Fhir_base_url]/Measure/TX-PVLS/$evaluate-measure?periodStart=<date>&periodEnd=<date>
Note that before the Measure is evaluted for Indicator , you load the necessary FHIR CQL Libraries for the Calculation of TX_PVLS into the Hapi Fhir.
