Superannuation Calculation for Employee Contribution

Hi Experts,

I have a requirement to have different logic in Payroll Calculations for Superannuation salary sacrifice % maintained in PA0220-EMPCN.

Basically in the standard payroll calculations, the Superannuation calculations return the Superable salary as the base for both Employer (SGC) and Employee contributions. For the Employer Contribution (SGC), the Wage Type is fetched only for Base salary and no overtime or allowances taken into consideration. Our business requirement is to take the Gross Salary as a base to work out the contribution.

Could anyone please outline how to achieve these two different logics in Payroll calculations?

Thanks.
