## 1. Role

### KKW22501SF01DBean.typeModelData()

This method implements a **type-mapping dispatch** pattern for the KKW22501SF screen module. Given a Japanese field name (`key`) and a subkey property (`subkey`), it returns the appropriate `Class<?>` type that the UI framework needs to construct data-binding model objects at runtime. It serves as a **shared type lookup utility** consumed by the webview data-binding infrastructure — every UI item rendered by this screen delegates through this method to determine whether a field's value, enablement flag, and status state are strings, booleans, or other types.

The method handles **9 distinct business fields** (items), each corresponding to a UI-bound data element on the service order change screen. These include agent (dealer) identification fields (代理店コード, 代理店名), display/filter configuration fields (表示用データ抽出項目コード, データ抽出項目コード, データ抽出項目設定条件番号), time fields (受付開始年月日时分, 受付終了年月日时分, 更新年月日时分秒), and a deletion flag (削除チェック). For each field, the method returns `String.class` for `value` and `state` subkeys, `Boolean.class` for `enable` subkeys (except for the deletion-check field which also returns `Boolean.class` for `value`), and `String.class` for `state`. Two of the nine fields — データ抽出項目コード（変更用）and データ抽出項目設定条件番号（変更用）— lack an `enable` subkey entirely. If no matching field is found, the method returns `null` (no matching property).

**Processing summary:**
1. **Null-guard**: If `key` or `subkey` is `null`, immediately return `null`.
2. **Separator index**: Compute `key.indexOf("/")` (result stored in local `separaterPoint`, but **never used** in any subsequent branch — dead code).
3. **9-way field dispatch**: Sequential `if-else if` chain compares `key` against 9 hardcoded Japanese field names. Each match delegates to a subkey-level `equalsIgnoreCase` check.
4. **Subkey resolution**: Within each field, return `String.class` or `Boolean.class` based on the subkey (`value`, `enable`, `state`). Fields 6–8 (変更用 fields and 更新年月日时分秒) do not support the `enable` subkey.
5. **Fallback**: If no field matches, return `null`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | Japanese field name (item name) identifying which UI-bound data element to resolve the type for. Examples: "代理店コード" (Dealer/Agent Code), "削除チェック" (Delete Check). Maps to internal item IDs such as `agnt_cd`, `del_check`, `dchskm_cd`. |
| 2 | `subkey` | `String` | Property subkey specifying which attribute of the field to resolve: `value` (the data value type), `enable` (the enable/disable flag type), or `state` (the display state type). Case-insensitive comparison (`equalsIgnoreCase`). |

**No instance fields or external state are read by this method.** It is entirely pure and stateless — the return value depends solely on the two input parameters.

## 4. CRUD Operations / Called Services

This method performs **no CRUD operations**, **no service component calls**, and **no database interactions**. It is a pure in-memory type-mapping utility that operates exclusively on its input parameters and returns a `Class<?>` reference.

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| (none) | — | — | — | No external calls; pure dispatch utility |

## 5. Dependency Trace

This method is a **leaf utility** consumed by other DBeans within the same codebase's data-binding infrastructure. Cross-reference search found many other `typeModelData` implementations in sibling/parallel DBeans (e.g., `FUW00912SF01DBean`, `FUW00926SF01DBean`), but the `typeModelData(String, String)` method defined in `KKW22501SF01DBean` has **no direct callers found** in the searched Java files. It is likely consumed indirectly through reflection or a generic data-binding framework that resolves type metadata at runtime for the KKSV screen module.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | N/A | Direct invocation not detected in codebase | Pure utility; no terminal SC/CRUD |

**Note:** This method follows the same signature pattern as sibling DBeans across the `FUW009xxSF` modules, suggesting it is part of a standardized `typeModelData` contract used by a generic webview rendering framework. Actual callers are likely in framework-level code not captured in the standard search scope (e.g., reflection-based bean metadata resolution).

## 6. Per-Branch Detail Blocks
