History Replacement engine
This feature replaces history for the period covering the minimum replacement start date and maximum replacement end date for the group.
Replacement Start Date is derived as the minimum start date from all base-level elements with a value populated for each group combination selected. If not populated for any base-level children of the aggregate element, this considers the lowest history index, that is the earliest history period.
Replacement End Date is derived as the maximum end date from all base-level elements with a value populated under each group combination selected. If not populated for any base-level children of the aggregate element, this considers the highest history index, that is the most recent history period.
