PCR for PF Admin Charges

Hi Experts,

PCR is calculating correctly for PF Admin Charges, edli charges etc. for PF. But as per our client, when they include VPF Amount then system should calculate "VPF Amount *100/12" and this should Add Base Wages i.e. Basic + DA (which is fluctuating every month). Adding Base Wages and VPF and then multiplying with 0.85% and then giving the answer.

For Example: If emp is contributing VPF Amount as Rs 1000 and Base Wages ( Basic + DA i.e. 10000 + 20000 = 12000)

Then what system should calculate VPF Amount as 1000*100/12 = 8333.33 + 12000 (Base Wages) = 20333.33

Now system should multiply 20333.33 * 0.85 /100 = 172.833305

Please help me!!!
