End Date
The End Date field on the Person Accruals screen represents when this user's association with a particular accrual plan will end. This date must fall within the begin and end date of the accrual plan itself. Also note that a user cannot have over lapping associations with the same accrual plan (with over-lapping date ranges).
When updating an existing association, you will not be permitted to move the end date such that it would be less than any posted accrual periods for this user (for this accrual association).
