@All: Thankyou so much for your detailed replies.

The organization has many employees born before 50/60 and don't have their Exact date of birth written on their National Identification Cards...

Thankyou Cadavre 🙂 It worked!

@tomm:

you are right It's a mistake Example Table would be

BudgetCodeId, EmpId, BudgetCode, Percentage

1, 1, US8765, 50

2, 1, US8543, 50

Now corrected table explains an employee having more than Budget Codes.
