# Bin

object type

A bin — the LEAF of the facility hierarchy (a Zone has one or more): where stock physically sits (inventory records pointer-reference bins, a bin holding stock can never be doomed or deactivated until the stock is moved). Parent = its Zone (NOT the family root). NOT a policy level.

## Fields

| Field | Type | Notes |
| --- | --- | --- |
| `id` | [ID](/types/#scalars) `ID!` | The record’s id — a UUID the platform assigned when the record was created; every reference to this record uses it. |
| `sysId` | [String](/types/#scalars) `String!` | The group-scoped human-facing system id (BN-…). |
| `type` | [String](/types/#scalars) `String!` | The kind of record — always `Bin` here. |
| `caption` | [String](/types/#scalars) `String!` | The record’s display name — what people see it called. |
| `status` | [String](/types/#scalars) `String!` | The FSM state: active \| inactive \| doomed. |
| `parentId` | [ID](/types/#scalars) `ID!` | The parent Zone; for a Bin parentId!== rootId. |
| `rootId` | [ID](/types/#scalars) `ID!` | The org-group family root. |
| `createdAt` | [String](/types/#scalars) `String!` | When the record was created, as a UTC timestamp. |
| `updatedAt` | [String](/types/#scalars) `String!` | When the record last changed, as a UTC timestamp. |
| `revisionNum` | [Int](/types/#scalars) `Int!` | How many times this record has been edited; the first save is 0. |
| `revision` | [ID](/types/#scalars) `ID!` | The OCC revision token — supply it on every mutation of this record; rotates on every write. |
| `refCaptions` | [RefCaption](/types/RefCaption/) `[RefCaption!]!` | The server-composed captions of this record's declared references (the referenced-caption rule) — one row per referenced id; see RefCaption. |
| `coordinates` | [String](/types/#scalars) `String!` | REQUIRED mutable locator within the parent Zone — free-form until the coordinate-standard policy lands (the standard is policy-selected, inherited zone from LF from org). |
| `code` | [String](/types/#scalars) | Optional mutable merchant reference code; uniqueness NOT enforced. |
