Subject: Re: Issues in interest recalculation Hi Adi, Thanks for your feedback. I already left some test cases on the demo (but have updated the same product in between so you'll need to check the derived data for these). I'll work on some more cases that we've seen locally tomorrow, but these are the ones that were already there. *Incorrect interest in Loan Schedule for first instalment when making an early payment* See https://demo.openmf.org/#/viewloanaccount/302, where you see 3.85 of interest paid on the summary and loan transactions, yet the 3.85 is still due on the instalment and if you look at the schedule via the API is reported as outstanding interest (which the transaction has already paid). [Adi] In case of interest recalculation enabled loans, there is no way to realise a complete EMI components whose due date is in the future. Any early payments gets adjusted to the principal, and hence there will be some interest component which will remain due as of the future due date. From calculations or schedule point of view the early paid amount is completely getting adjusted to Principal and interest is pending. Repayment strategy decides the splitting of components in a transaction. Looks like the repayment strategy needs a correction not to consider the interest component in case of early payment. *Interest recalculation causes incorrect schedule with duplicate instalments* For the daily loans with duplicate instalments see: https://demo.openmf.org/#/viewloanaccount/304, where you can see that 2 payments fall due on the same day. If you undo disburse the loan and preview the schedule before disbursement you'll not see duplicate payments on the same day. [Adi] As I see original schedule is fine, but during repayments some duplicates are seen. This is definitely a bug.
