Zero coupon bond incorrect amortized value

Hello

I have configured a Zero Coupon bond, using the Amortization procedure as below. (Amortization procedure 1000)

Above Amortization procedure is assigned to my PMP SAME

In the above PMP, I activated only the Amortization step.

Now my class id is created as below

In the above, I ticked the end of term checkbox

My simulation details are as below

In the above also, I checked the start date 01.09.2016.

After the above transaction posting to FI, when I did the monthly amortization (TPM1), System allows me to do valuation on each month end date until Oct 2016. However on last month (Nov 2016), I am able to run the valuation on Nov 29th (instead of 30th), and as a result, my amortization is done for 1 day less

I would be so grateful if someone can confirm me that if the Bond duration is say Sep 01, 2016 till Nov 30, 2016, then how shall I maintain the class id, and how should I simulate the transaction so that my amortized amount is FULLY recovered (in the above case, INR 22000)

Appreciate your help
