What is the OnCore definition/functionality of On Study?

On Study is defined as the date the study subject has been registered to the study after having completed the eligibility step and has received a subject ID from the sponsor. The On Study date is the required date in OnCore for accrual credit. It is not related to billing. In the CTMS workflow, subjects will be marked as Billing Active in Epic as soon as they have consented to the study and have a consented date recorded in OnCore.
