Need Validation while entering the salary

Summary:

We are using this salary basis type : Salary amount is determined by simple components. we have added the required components and enabled following configuration

When adding salary using above salary basis, currently system is not validating total percentage or total amount.

Expected outcome is : User will enter Gross salary, and will enter the percentages for Basis and allowances.

Eg : Gross salary - 10,000 (user will enter the amount)

Basis Salary : 70% (user will enter the percentage) - 7000 (should calculate automatically)

Allowance : 30% (user will enter the percentage) - 3000 (should calculate automatically)

Overall : 10,000 (automatically calculated).

Above configuration is working as expected. But system is allowing user to enter percentages more than 100.
