/3C4 wage type

Dear All,f

I have two reimbursements for Car:

1. Conveyance allowance as per standard laws, monthly exempted Rs. 1600

2. Car Hiring reimbursement on which driver and car perk is calculated, monthly exempted fully

Now I have maintained WTs for both, Conveyance- 1008 & Car hiring reimbursement- 1016. When I run PY:

The amount in WT /3C4 comes as 10000.

The eligibility of employee for Car hiring reimbursement is 1000/month.

Same amount is reflecting in /3C3

Total gross has increased by Rs. 10000- this is an error
