How to make input value of an element dependent on the grade of an employee?

Summary:

Hello,

We are currently implementing the Oracle Fusion Compensation module.

We have a customer requirement where they want to assign Car Allowance Plan to employees who are of Grade 14 and above. We have created a Car Allowance element and attached it to a Car Allowance Plan. When assigning the Car Allowance Plan, via Individual Compensation, to the employee, the customer would like the Input value to be automatically filled based on the Grade of the employee.

For example: Employees with Grade G14 should have an input value of Rs 3000 and employees with Grade G15 should have an input value of Rs 5000.
