## 1. Role

### KKW14301SF03DBean.listKoumokuIds()

This method serves as a **display label provider** for the Discount/Campaign Code List (割引／キャンペーンコードリスト) data type within the KKW14301SF order inquiry screen. It returns a pre-defined list of six Japanese column headers that define how a discount/campaign code data table is rendered in the UI — effectively acting as the column definition registry for that specific data type bean.

The method implements the **Data Type Bean pattern** common in the X33 framework: each DBean class supplies its own set of display labels via a static `listKoumokuIds()` method, allowing the parent bean (`KKW14301SFBean`) to dispatch to the correct label list based on the data type key string. This method is one of five such DBeans (`KKW14301SF01DBean` through `KKW14301SF04DBean`, plus others), each covering a distinct service category on the inquiry screen.

The six items it provides correspond to the business data model for discount/campaign code entries: internal code, display name, order start date, order end date, application method, and discount/campaign code list style. The method has no conditional branches — it is a pure factory that builds and returns a fixed ordered list.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["listKoumokuIds()"])
    CREATE["Create ArrayList"]
    A1["Add: Code"]
    A2["Add: Name"]
    A3["Add: Order Start Date"]
    A4["Add: Order End Date"]
    A5["Add: Application Method"]
    A6["Add: Discount Campaign Code List Style"]
    RET["Return list"]

    START --> CREATE
    CREATE --> A1
    A1 --> A2
    A2 --> A3
    A3 --> A4
    A4 --> A5
    A5 --> A6
    A6 --> RET
```

This method performs a simple linear sequence: it instantiates an `ArrayList<String>`, appends six display label strings in a fixed order, and returns the list. There are no conditional branches, loops, or method calls beyond `ArrayList.add()`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | This method takes no parameters; it is a static factory with no inputs. |

## 4. CRUD Operations / Called Services

This method performs no database operations, service component calls, or entity accesses. It is a pure presentation-layer utility that constructs an in-memory list of display labels.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| (none) | — | — | — | No CRUD operations — pure factory method returning display label strings. |
