Loan - Interest Fix Rate Method on Principal amount.

Dear Experts,

I have configured the Loan - IT0045.  I want to calculate Interest by fix rate method on Principal amount i.e. Rs.45000/-

Now I am getting Interest by reducing balance method on balance amount.

Scenario is as follows:

Principal: 45000/-

Interest: 10% - Flat/Fix & up to last instalment should be deduction on Rs.45000 principal. Period: 60 Months

Instalment: 750/-

Thanks in advance.

Regards,
