Hi Priya,
This is entirely depends upon how we manage/adjust due dates as per our requirement. Once we entered variable interest for the current we cannot edit/adjust interest condition as well as installment condition also.
Reverse interest rate entered for the current period by TI37 and do the required adjustments for interest and installments.
We can adjust our interest/installment due date by using condition tab.
Thanks,
