## 1. Role

### KKW01034SF03DBean.listKoumokuIds()

This method serves as a **static data source** that provides a predefined list of field identifiers (item names / "koumoku IDs") used by the KKW01034SF screen module for campaign management operations. It returns an `ArrayList<String>` containing 30 Japanese-language display labels — each representing a UI field that appears on the campaign-related web screens. The method implements the **factory method / data provider** design pattern: it is invoked by the parent `KKW01034SFBean.listKoumokuIds(String key)` dispatcher method, which routes requests to this bean's implementation when the requested item key matches the campaign list identifiers ("キャンペーン一覧" or "キャンペーン一覧2"). It acts as a **shared utility** shared across multiple screen controllers within the `KKW01034SF` module, supplying the canonical field set for campaign data type beans that support data-type-driven UI generation (where field labels are resolved at runtime based on the key parameter). No conditional branching, no database calls, and no instance state — the method is a pure factory that returns a constant list.

```

This method has **no conditional branches** — it is a linear sequence of 32 operations: one initialization followed by 30 `add()` calls and one `return`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | This is a `static` method with no parameters; it returns the complete predefined field list for the campaign data type bean. |
| - | `koumokuList` (local) | `ArrayList<String>` | Internal accumulator that collects the 30 campaign field identifiers before being returned. |

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations**. It makes no service component (SC) or callback stub (CBS) calls. It does not interact with any database tables or entities. It is a pure in-memory factory that constructs and returns a static list of string labels.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| N/A | N/A | N/A | N/A | This method performs no data access operations. |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Bean:KKW01034SF | `KKW01034SFBean.listKoumokuIds("キャンペーン一覧")` → `KKW01034SF03DBean.listKoumokuIds()` | N/A (no database access) |
| 2 | Bean:KKW01034SF | `KKW01034SFBean.listKoumokuIds("キャンペーン一覧2")` → `KKW01034SF03DBean.listKoumokuIds()` | N/A (no database access) |

**Notes:**
- The two callers identified above are within `KKW01034SFBean.java` (the parent/owner bean class).
- Caller line 2779 routes when the `key` parameter equals `"キャンペーン一覧"` (Campaign List).
- Caller line 2894 routes when the `key` parameter equals `"キャンペーン一覧2"` (Campaign List 2).
- The method is **not** called directly by any screen class (KKSV*) or CBS/C controller. It is exclusively invoked through the dispatcher pattern in its owning bean.
- No downstream SC or CBS calls exist — the method is self-contained with no terminal CRUD endpoints.

## 6. Per-Branch Detail Blocks

> **Block 1** — INIT `(variable declaration)` (L1718)

Initialize the local accumulator list that holds campaign field identifiers.

| # | Type | Code |
|---|------|------|
| 1 | SET | `ArrayList<String> koumokuList = new ArrayList<String>();` // Create empty list for 30 campaign item labels |

> **Block 2** — SEQUENCE `(sequential add operations)` (L1719–L1748)

Populate the list with 30 Japanese-language campaign field names in a flat, sequential order. Each `add()` call pushes a string constant representing a UI column identifier.
