Partial payment and interest against Loans in Treasury

Hi Folks,

I have taken loan 100,000 with 2% interest for 1 year. I want to make the payment 60,000 after 6 months.I have used product category 550.

The system is calculating partial payment and interest for the partial amount correctly and showing under cash flows.But business want to make the partial payment along with interest after 6 months. But system is showing cash flows only at the end of the period (12 months). We are using fixed interest rate.  Is there a way to make the partial interest payment along with partial repayment of principal value?
