PF deduction for specific ESG

Hi Experts,

My client wants to deduct Provident Fund Contribution on Salary Package instead of Basic + HCA for specific employee group.

For example : we have below wagetypes as one pay scale structure.

in our current process, PF deduction is happening on Basic Salary (9BIC) + HCA (9HCE) for all employees. 9SAL =9BIC +9HCE +9HRA

where 9BIC = 60% of 9SAL,

          9HCE =30 % of 9SAL,

          9HRA = 10 % of 9SAL.

Now the requirement is to deduct PF on Salary Package (9SPA) on specific employee group.

Any expert help will be highly appreciated.

Thanks in advance.
