## 1. Role

### CRW03407SF03DBean.loadModelData()

This method serves as a **data router and dispatcher** for the campaign information detail section of the K-Opticom telecom service order screen. It provides a unified entry point that the web view layer uses to retrieve structured data for six UI model fields, each supporting three access modes: value, enable (read-only flag), and state (display status). The method implements a **routing/dispatch pattern** — it evaluates the `key` parameter against predefined Japanese field names, then further narrows by the `subkey` parameter to route to the appropriate getter method. Within this class, it delegates exclusively to internal getter methods (`getL2_*`), which in turn read from the bean's own instance fields (no external service or database calls). This method's role in the larger system is to **bridge the UI data-binding framework** (X33VDataType*) with the concrete L2 (second-level) data fields, enabling dynamic form rendering where rows can be individually enabled, disabled, or shown in various states. It is a shared utility called by the parent form bean's list-item processing chain when iterating over campaign information rows.

**Processing flow summary:**

1. **Null guard** — If either `key` or `subkey` is null, return null immediately. (Japanese comment: key, subkey がnullの場合、nullを返す — Return null if key/subkey is null)
2. **Separator scan** — Compute `key.indexOf("/")` to determine if a hierarchical key path was provided. The variable `separaterPoint` is stored but not subsequently used in this method.
3. **Key-based routing** — Chain of six `if/else-if` branches matching the `key` against hardcoded Japanese field name constants. Each branch further dispatches on `subkey` case-insensitively:
   - **明細インデックス** (Detail Index, field ID: `l2_detail_index`) — supports `value`, `enable`, `state` subkeys
   - **キャンペーンコード** (Campaign Code, field ID: `l2_dsp_campaign_cd`) — supports `value`, `enable`, `state` subkeys
   - **キャンペーン名** (Campaign Name, field ID: `l2_wrib_svc_nm`) — supports `value`, `enable`, `state` subkeys
   - **適用月** (Application Month, field ID: `l2_wrib_svc_tstaymd`) — supports `value`, `enable`, `state` subkeys
   - **行スタイルクラス** (Row Style Class, field ID: `l2_line_style_class`) — supports `value`, `state` subkeys (no `enable`)
   - **行スタイルID** (Row Style ID, field ID: `l2_line_style_id`) — supports `value`, `state` subkeys (no `enable`)
4. **Fallback** — If no matching key is found, return null. (Japanese comment: 条件に合致するプロパティが存在しない場合は、nullを返す — Return null if no matching property exists)

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The business field identifier (item name) that selects which of the six campaign data model fields to access. Must match one of the hardcoded Japanese field names: 明細インデックス, キャンペーンコード, キャンペーン名, 適用月, 行スタイルクラス, or 行スタイルID. The presence of "/" in the key is detected (via `indexOf`) for potential hierarchical routing but is not currently used for sub-dispatch in this method. |
| 2 | `subkey` | `String` | The access mode for the requested field, specifying whether to retrieve the data value (`"value"`), the enabled/read-only flag (`"enable"`), or the display state (`"state"`). Comparison is case-insensitive (`equalsIgnoreCase`). Not all fields support all subkeys — "行スタイルクラス" and "行スタイルID" only support "value" and "state", omitting "enable". |

**Instance fields read:**

|-------|-------|-------------|
| `l2_detail_index_value`, `l2_detail_index_enabled`, `l2_detail_index_state` | `CRW03407SF03DBean` | Detail index data, enable flag, and state |
| `l2_dsp_campaign_cd_value`, `l2_dsp_campaign_cd_enabled`, `l2_dsp_campaign_cd_state` | `CRW03407SF03DBean` | Campaign code data, enable flag, and state |

| `l2_wrib_svc_tstaymd_value`, `l2_wrib_svc_tstaymd_enabled`, `l2_wrib_svc_tstaymd_state` | `CRW03407SF03DBean` | Application month data, enable flag, and state |
| `l2_line_style_class_value`, `l2_line_style_class_state` | `CRW03407SF03DBean` | Row style class data and state (no enable) |
| `l2_line_style_id_value`, `l2_line_style_id_state` | `CRW03407SF03DBean` | Row style ID data and state (no enable) |

All 16 calls are **Read (R)** operations — pure getter delegation to the bean's own L2 instance fields. No SC (Service Component), CBS (Common Business Service), database tables, or entity persistence is involved in this method. It is a pure **in-memory data retrieval** method that maps UI-level key/subkey lookups to bean field accessors.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:CRW03407SF (indirect) | `CRW03407SFBean.buildItemList` -> `X33VDataTypeBeanInterface.loadModelData` | `getL2_* methods [R] bean instance fields` |

**Caller analysis details:**

The primary caller is `CRW03407SFBean` (the parent form bean). In its item list building methods, the bean creates rows containing data-type beans (such as `CRW03407SF03DBean` for "キャンペーン情報詳細" — Campaign Information Detail). When the UI framework needs to populate field values, it calls `loadModelData(subkey)` on the individual row bean. The call chain originates from the screen processing layer where the form bean iterates over list items and invokes the bean's `loadModelData` method for each field key.

No other classes were found directly calling `CRW03407SF03DBean.loadModelData(String, String)`. Other `loadModelData` matches in the search results belong to sibling DBean classes (CRW03407SF01DBean through CRW03407SF09DBean) and unrelated FW* series beans, which implement their own independent routing logic.
