Bug fixes​

Lending​

Interest calculation accuracy for revolving loans​

Addressed a calculation error where payoff transactions used a lower interest amount than the repayment schedule. This fix ensures the correct interest is applied during settlement, preventing cases where an account is closed but still shows a balance due in the schedule.

Principal-based interest calculation for paid-off accounts​

In some edge cases where an account was fully paid off, interest could still be calculated based on an incorrect principal amount from the schedule. With this update, the calculation now correctly uses the actual transaction-based principal, ensuring that no interest is accrued when an account's true outstanding balance is zero or less.

Billing cycle interest calculation after disbursements​

Previously, after a new disbursement within a billing cycle, the interest due for an installment could sometimes be incorrectly inflated. The calculation now considers only the principal balance applicable to that specific billing period.

Loan account validation for PATCH requests​

Fixed an issue where PATCH requests to update loan accounts incorrectly triggered validation against current loan product constraints for fields not included in the request. Validation is now applied only to fields explicitly modified in the API payload.

Transaction search API custom field filtering​

Fixed an issue where the /api/loans/transactions:search API returned internal errors when filtering by custom fields such as _lendingAccount. The system now correctly processes search requests that include custom field filters.

Interest reduction display in repayment schedules​

We've fixed a bug where interest reductions from a loan payoff were not correctly reflected in the repayment schedule. Previously, this caused the final payment to incorrectly show a remaining interest balance even after the loan was fully paid off.

Reschedule operations for redraw-enabled accounts​

Fixes an error that occurred when performing the reschedule action on accounts with the redraw feature enabled.

Non-customer-facing lending performance improvements.

Deposits​

Overdraft modification restrictions for locked accounts​

Previously, it was possible to change overdraft terms (such as the overdraft limit) on a savings account while it was in a locked state. This action, however, did not correctly log a corresponding transaction. With this release, we have fixed the issue. It is no longer possible to modify the overdraft terms of a savings account while it is locked.

Deposit account state error handling​

As part of this fix, we have corrected the error returned when an operation is attempted on a deposit account that is not in a valid state. The API will now correctly return the INVALID_DEPOSIT_ACCOUNT_STATE (407) error instead of the previous, incorrect loan-specific INVALID_ACCOUNT_STATE (105) error.

Non-customer-facing deposit configuration fixes.

Mortgages​

Non-customer-facing mortgage calculation and interface fixes.

Cards​

Non-customer-facing cards transaction processing improvements.

Islamic Banking​

Non-customer-facing Islamic banking product configuration and profit calculation fixes.

Developer​

Resolved errors occurring when retrieving mortgage schedules through the API.

Fixed PMT threshold validation for redraw repayments with broken interest​
