Transfer Absence balance from non-primary assignment to primary assignment plan when non-primary end
When employee having multiple assignments, we would want to transfer a positive balance from non-primary assignment plan to primary assignment plan when non primary assignment got ended.
1. An Employee is having multiple assignments ASS1 and ASS2 (One is primary and the other one is non-primary).
ASS1 is eligible for AB_PLAN_1 with 10 days of balance (Primary Assignment) and
ASS2 is eligible for AB_PLAN_2 with 2 days of balance (Non-Primary Assignment)
2. Now ASS2 is Ended using 'End Assignment' Action.
3. When ASS2 ended, the left-over balance (2 days) should be transferred to existing ASS1 assignment absence plan AB_PLAN_1 from AB_PLAN_2.
