returns: reverse a refunded debit-note return whose goods never reached the warehouse
Once a return was refunded nothing could undo it - rejectReturn refuses an already
refunded one - so a return booked and paid for goods that never arrived left phantom
warehouse stock, the unit missing from partner stock, the order marked returned, a
wallet credit and a filed credit note, with no way back.
ReturnReversalService.reverse(imei, reason, by, dryRun) undoes exactly one unit:
the warehouse return scan (row deleted so a genuine return later is not rejected as a
duplicate) and the stock it added, partner stock with its schemes/price drop/offers,
the order's return quantity and status, the wallet refund as a REVERSAL entry, and the
return item / debit note. Guards refuse anything that has moved since the refund, and a
dry run reports the plan without writing.
The credit note follows movement and the NIC clock: inside the 24h window, and only
when the note credits nothing but this unit, its IRN is cancelled and the note marked
cancelled; past it a DBN with its own IRN is issued against the note
(CreditNoteService.issueReturnReversalDebitNote, stored as CN_CANCELLATION with no
margin month so the statement does not show it twice - the wallet REVERSAL is the
statement line); a note never filed at NIC is voided locally. Every local write happens
first and NIC last, so a refusal rolls the whole reversal back.
fofo.return_reversal (return_reversal_20260921.sql) records each reversal and, unique
per return item, makes it once-only. Also adds cancelled=0 to the RETURNS_CN branches of
the account statement queries, without which a cancelled note keeps crediting the
statement - no current effect, no RETURNS note is cancelled today. |
