Hi Team,

Am trying to understand how an event change is being tracked in Oracle HCM cloud system. We see the event changes are being captured in the table HRC_EVT_OBJ_CHANGES tables. but not sure when exactly this table will get data?

1. does it capture transactions of a pending worker?

2. What is validation start date/end date in this table?

3. when there is a change in Effective end date how it captures that data?

4. PER_PERIIODS_OF_SERVICE - what are all the field changes captured in event object changes table when there is a change in . PER_PERIIODS_OF_SERVICE
