Modifying the salary slip

Hi,
I am Implementing the loan feature in the salary slip. I have checked the code of payroll, while creating the salary slips in payroll the amounts are automatically calculated and inserted in the db. I am not able to find the code corresponding to amounts.
Thanks in advance
