Aman-Mittal opened a new issue, #506:
URL: https://github.com/apache/fineract-backoffice-ui/issues/506
## What is missing
The app offers three refund-shaped transactions — Merchant Issued Refund,
Payout Refund and Goodwill Credit. The platform accepts two more that have no
UI at all.
Confirmed against a running `apache/fineract` using the #268 discriminator,
where an unrecognised command answers
`error.msg.query.parameter.value.unsupported` on the `command` parameter:
| Probe | Result |
|---|---|
| `POST /loans/{id}/transactions?command=totallyNotACommand` |
`error.msg.query.parameter.value.unsupported` — **unrecognised** (control) |
| `POST /loans/{id}/transactions?command=writeoff` |
`validation.msg.loan.transaction.transactionDate.cannot.be.blank` —
**recognised** (control) |
| `POST /loans/{id}/transactions?command=refundByCash` |
`validation.msg.loan.transaction.transactionDate.cannot.be.blank` —
**recognised** |
| `POST /loans/{id}/transactions?command=chargeRefund` |
`validation.msg.loan.charge.refund.transaction.loanChargeId.cannot.be.blank` —
**recognised** |
Permissions `REFUNDBYCASH_LOAN` and `CHARGEREFUND_LOAN` are both present in
`GET /permissions`.
## What the UI offers today
The Actions menu on a real progressive Active loan — 17 entries, neither
refund among them:

## The two halves are not the same size
**Refund by cash** needs only a date and an amount, which is exactly what
the existing generic transaction form already sends.
`loan-transaction-form.component.ts` is driven by the route's `:type` parameter
and posts `postLoansLoanIdTransactions(loanId, transaction, type)` with
`transactionDate`, `dateFormat`, `locale`, `transactionAmount` and
`paymentTypeId`. Adding it is a menu entry, a title key, `AMOUNT_VISIBLE_TYPES`
membership and an i18n string — no new form.
**Charge refund** additionally requires `loanChargeId`, so it needs a picker
listing the loan's charges. That is a genuinely new field on the shared form,
and worth doing separately rather than bolting onto the simpler change.
## A stale comment to fix while in here
`loan-transaction-form.component.ts:406` says:
> the transaction *template* endpoint accepts fewer commands than the
transaction endpoint itself — reAmortize, chargeRefund and undowriteoff are
rejected there with "unsupported value" even though the POST works.
But `NO_TEMPLATE_TYPES` is `{ approve, undoDisbursal, reAmortize,
undowriteoff }` — `chargeRefund` is **not** in the set the comment describes.
Today that is harmless, because nothing can reach the form with that type. The
moment charge refund is offered, the form will issue a template request the
comment already predicts will fail. Either the comment is wrong or the set is
missing an entry, and whoever implements charge refund needs to settle which.
## Why it is worth doing
Refund by cash is how an over-payment is handed back across the counter —
the ordinary counterpart to taking a repayment, and the one refund route that
needs no card or wallet rail behind it. Charge refund reverses a fee that
should not have been levied, which today can only be approximated with a
goodwill credit; that records a gift rather than a correction, and the two are
not the same thing in the ledger.
## Environment
`main` at `7c51d90b`. Probes against `apache/fineract` running locally via
`deploy/docker-compose-e2e.yml`; screenshot from a loan seeded with the
repository's own `e2e/utils/seed-api.ts` helpers.
