# M18 `udfProducttype` → MTMS `items.type`

_Generated: 2026-08-01 10:01 UTC_

**Source of truth**

- Enums: `NewItemRequest.kt` → `ItemType`, `M18ItemType`
- Sync: `M18MasterDataService.saveProduct` / `saveProducts` (`when (pro.udfProducttype)`)
- UI labels (inventory): `FPSMS-frontend/src/i18n/zh/inventory.json`

## Sync mapping

| M18 `udfProducttype` (exact string) | `M18ItemType` | MTMS `items.type` | `ItemType` | Inventory UI (zh) |
|---|---|---|---|---|
| `Consumable Material` | `CONSUMABLES` | `consumables` | `CONSUMABLES` | 消耗品 |
| `Non-consumable Material` | `NONCONSUMABLES` | `non-consumables` | `NONCONSUMABLES` | 非消耗品 |
| `Product` | `FG` | `fg` | `FG` | 成品 |
| `WIP` | `SFG` | `sfg` | `SFG` | 半成品 |
| `Item` | `ITEM` | `item` | `ITEM` | 貨品 |
| *(any other value / empty)* | — | `mat` | `MATERIAL` | 原料 |

## Enum inventories

### `M18ItemType`

| Constant | String value | Used in sync `when`? |
|---|---|---|
| `CONSUMABLES` | `Consumable Material` | yes |
| `NONCONSUMABLES` | `Non-consumable Material` | yes |
| `FG` | `Product` | yes |
| `SFG` | `WIP` | yes |
| `ITEM` | `Item` | yes |

### `ItemType` (MTMS stored values)

| Constant | `items.type` | Inventory UI (zh) |
|---|---|---|
| `MATERIAL` | `mat` | 原料 |
| `CONSUMABLES` | `consumables` | 消耗品 |
| `NONCONSUMABLES` | `non-consumables` | 非消耗品 |
| `FG` | `fg` | 成品 |
| `SFG` | `sfg` | 半成品 |
| `ITEM` | `item` | 貨品 |

## Known gaps (not auto-mapped)

| M18 value seen | Effect | Notes |
|---|---|---|
| `CMB` | → `mat` (else) | Seen on M18 pro.udfProducttype (e.g. MG1852). Falls through to mat. |

Frontend Settings → Items edit also offers `cmb` / `wip` / `nm` as local types;
those are **not** written by the current M18 `udfProducttype` mapper.
