# doomPromotion

mutation · in the family [Promotion](/reference/promotion/)

## What it does

Permanently retire a promotion — an automatic price rule.

Doom (terminal) a Promotion by id, within the caller's org group; requires the unrestricted capability + the record's CURRENT revision. The referential-integrity guard blocks while NON-doomed trigger Coupons reference it (CONFLICT/REFERENCED naming first-8 — doom or re-point them first); deactivate stays FREE. NO doom-time enumeration of open orders (the RC-n write-time-only stance) — stored engine entries self-heal at the next recompute and PLACE re-validates.

## Careful

Doom is forever — a doomed record never comes back into use (its history remains readable). Anything still referencing it live will block the doom.

## Who may call it

Capability area: **Pricing** — Prices, price schedules, promotions, coupons and the money rules of selling.

## Arguments

| Name | Type | Required | Notes |
| --- | --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | yes | The id of the record. |
| `revision` | [ID](/types/#scalars) `ID!` | yes | The revision id you read on the record; the change is refused if an edit landed in the meantime. |
| `reason` | [String](/types/#scalars) | no | No further notes. |

## Returns

[Promotion](/types/Promotion/) `Promotion!` — A Promotion — the rule-based discount engine that EMITS source=promo LINE discount entries at the step-2 position 3 (after manual + coupon; the pipeline math was position-complete from birth — the build ANIMATES the dormant slot, the pattern). Org restriction is JUNCTION-LESS: the scope axes (channels/LFs/orgs) gate WHERE it fires; productScope (the CollectionPredicate VERBATIM + inclusions/exclusions + a Collection ref) gates WHAT lines match — ABSENT productScope = ALL product lines (the sitewide sale; open_item lines never match); cartConditions gate WHEN. Windows are half-open \[startAt, endAt) — an EVALUATION gate, never FSM states (advance scheduling = create active with a future startAt; absent endAt = evergreen). Resolution is STRICT no-stack (priority asc, id asc; combinableGroup opts IN; exclusive blocks its lines). Emissions are ABSOLUTE amount entries computed to replay VERBATIM in the pipeline; order-target effects pre-allocate largest-remainder over the MATCHED lines ONLY. Redemptions count per ORDER in the place/accept transaction; a capped-out promotion silently STOPS FIRING. At most 128 ACTIVE per org group.
