## 1. Role

### KKW02701SF02DBean.loadModelData()

This method serves as a **property-based data access router** for the KKA16701SF screen's data bean. Its business purpose is to provide a unified, key-driven interface for reading typed field values, display states, and enable flags across a range of service-order-related fields displayed on a telecom service contract detail screen. It implements a **routing/dispatch pattern**: incoming string-based item names (`key`) are matched against known Japanese-labeled field identifiers, and then a subkey (`value`, `state`, `enable`) determines which accessor method to delegate to. The method supports 11 distinct data properties, each representing a business field on a service order screen (e.g., service contract detail number, registration timestamp, course name, mansion details, pricing codes). For the "status" and "course application date" fields, it additionally exposes an `enable` flag that indicates whether the field is currently editable on the UI. The method does NOT perform any CRUD operations or business logic — it purely routes to getter methods on the same bean. Its role in the larger system is to support the X31C web framework's data binding mechanism, allowing the view layer to request field data by human-readable labels rather than internal variable names. If an unrecognized key is provided, the method returns `null`, making it safe for use in dynamic lookup scenarios.

**Processing Summary:**
The method follows a linear if/else-if cascade pattern. For each of the 11 key branches:
- **"value" subkey**: Returns the field's current data value (String or numeric type).
- **"state" subkey**: Returns the field's display/state flag (typically indicating read-only or display mode).
- **"enable" subkey** (only for `stat`, `course_aply_ymd`, `course_nm`, `mansion_id`, `mansion_nm`, `new_pcrs_cd`, `old_pcrs_cd`): Returns the field's enabled/editable flag.

If `key` or `subkey` is null, returns `null` immediately. If no key matches, falls through to the final `return null`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The human-readable Japanese label of the screen field whose data is being requested. Each value maps to one business property on the service order detail screen. Possible values: `サービス契約内訳番号` (Service Contract Detail Number), `世代登録年月日時分秒` (Registration Timestamp), `異動予約番号` (Move Reservation Number), `申込明細番号` (Application Detail Number), `状態` (Status), `コース適用年月日` (Course Application Date), `コース名` (Course Name), `マンションID` (Mansion ID), `マンション名` (Mansion Name), `新料金コースコード` (New Pricing Course Code), `旧料金コースコード` (Old Pricing Course Code). Case-sensitive match. |
| 2 | `subkey` | `String` | The data accessor type within the matched key. Valid values (case-insensitive): `value` (returns the field's current data value), `state` (returns the field's display state flag), `enable` (returns whether the field is editable — only valid for certain keys). |
| 3 | `key.indexOf("/")` result | `int` | Internal variable `separaterPoint` — computes the position of "/" in `key`. **Note: This value is computed but never used in any subsequent logic.** |

**No instance fields or external state** are read by this method. It delegates entirely to its own getter methods.

**Analysis:** This method performs **exclusively Read (R) operations**. It contains no database access, no SC/CBS calls, no entity operations, and no create/update/delete logic. All 29 called methods are getter accessors defined on the same `KKW02701SF02DBean` class, returning field values and UI state flags.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0004 (example) | `KKSV0004` screen controller -> view binding -> `KKW02701SF02DBean.loadModelData(key, subkey)` | getter methods [R] in-memory bean fields |

**Notes on callers:** The pre-compiled evidence from the search shows that `loadModelData` is a widely-used pattern across many webview beans (e.g., `FUW00912SF01DBean`, `FUW00926SFBean`, `FUW00964SFBean`). These beans follow a similar routing pattern, calling `loadModelData` with Japanese-labeled keys to retrieve field data from their respective DBean. The method is part of the X31C web framework's data binding convention, where the view layer requests data by human-readable labels. The specific callers of `KKW02701SF02DBean.loadModelData` would be in the `KKA16701SF` screen's controller/view layer, which is not present in the scanned result set.
