Uk Absence - Enable Multiple assignment - what will happen to existing ongoing/inflight absences

Summary:

Hi,

We are planning to enable multiple assignment processing as per Oracle guide by running ''Run Feature Upgrade''. But there is no information on existing absence entries. After the transition process what will happen to the existing absence entries that will end date after the transition date or which have open end date?

Eg: Employee having multiple assignments but with existing setup, the absence entries/calculation cards are created only for the primary assignment. Now after enabling the transition process for enabling multiple assignments, do we need to run any process so that existing absence entries/calculation cards gets recreated based on the new transition process for all active multiple assignments?
