Transaction templates and request contracts src/app/loans/common-resolvers/..., src/app/loans/loans.service.ts, src/app/loans/models/working-capital/... |
Working capital actions use typed transaction templates. Prepayment templates include transaction-date parameters. New models define prepayment templates and repayment requests. |
Prepayment action menu integration src/app/loans/loans-view/loans-view.component.ts, src/app/loans/loans-view/loan-accounts-button-config.ts, src/app/loans/loans-view/loan-account-actions/..., src/app/loans/loans-view/loans-view.component.spec.ts |
Active loans expose prepayment independently of interest recalculation. Working capital loans use a permission-gated Prepay Loan action and the dedicated component. |
Working capital prepayment form src/app/loans/loans-view/working-capital/loan-account-actions/prepay-loan/*, src/assets/translations/* |
The form displays payoff amounts, validates dates and amounts, supports optional payment details, submits repayment commands, and includes translated validation messages. Tests cover initialization, payload construction, validation, duplicate submission, and navigation. |

Merge Risk: 🟡 Moderate · up to ccfca
Prepay Loan can submit a partial repayment instead of closing the loan when the quoted amount is edited. The full-payoff invariant should be enforced before merge.

- Line 163: Replace gap-5px in the mat-card-actions markup with the existing
8px-grid spacing utility. In prepay-loan.component.scss lines 14-18, replace
literal pixel spacing with the appropriate shared spacing variables from the
theme or main stylesheet; update both affected sites while preserving the
existing layout behavior.
- Line 22: Update the prepayment form around transactionAmount and submit() so
users cannot submit a partial or altered payoff: make transactionAmount
read-only or constrain it to payoffAmount with exact-value validation, while
preserving the existing transactionDate behavior.

- Line 157: Update the prepay submission flow to disable the editable
transactionAmount control and use this.payoffAmount when constructing the
repayment payload, rather than the form value. Add a regression test that
changes the control value and verifies the submitted payload retains the quoted
payoff amount.

- Around line 702-704: Update the documentation comments in
getWorkingCapitalLoanTransactionTemplate and the related Working Capital
template method: remove disburse from the lifecycle-action description at

disburse uses the transaction-template endpoint.

Description
Added 'Prepay Loan' option for working capital loans. It queries the backend for a repayment template for the full remaining outstanding amounts.
Also noticed 2 other issues which is being fixed in this pr.
Issue nr 1:
recalculateInterest in loans-view component wasn't being used correctly. It's set in one place with:
this.recalculateInterest = this.loanDetailsData?.recalculateInterest || true;which is always truthy andrecalculateInterestdoesn't exist on the loan details payload. The actual field isisInterestRecalculationEnabled.It's used to gate two buttons:
Add Interest Pause: should be gated.
InterestPauseWritePlatformServiceImplrejects the request withloan.must.have.recalculate.interest.enabledwhenisInterestRecalculationEnabled()is false.Prepay Loan: should never have been gated. Paying off a balance has nothing to do with interest recalculation; the prepay template works on any loan. It was sitting near the interest-pause block and inherited the wrong condition. Now unconditional for active loan products.
Issue nr 2:
Term loans offer two endpoints from which templates can be read, we have the
/template?templateType=endpoint for loan lifecycle events, and then the/transactions/template?command=for transaction templates. What WC did earlier was cram eight transaction templates onto the lifecycle endpoint, making the boundary between the two endpoints look arbitrary.I have migrated the existing transaction templates to the new transaction template endpoint that is created with the simultaneously running backend PR. The split is now lifecycle vs. transaction, matching core:

progressive loan product with interest recalculation disabled now correctly hide the interest pause button, backend would reject it anyway:
Still there for interest recalculation enabled products:
