## 1. Role

### KKW01021SF02DBean.loadModelData()

This method is a **property accessor router** for the contractor (customer) address and identity fields used by the KKW01021SF screen - a web view form that displays and edits customer contract information including the contractor's name, full address, and a system identifier. It implements the **routing/dispatch pattern**, branching on a `key` string that identifies a specific business field and a `subkey` that identifies which property facet (value, enabled-state, or display-state) of that field should be returned. The key is a Japanese-display field label (e.g. "CLIENT_NAME" for Customer Name, "CONTRACTOR_PHONE" for Contractor Phone Number) and the subkey maps to the three standard X33 bean facets: "value" returns the data, "enable" returns the editability flag, and "state" returns the display state code. This is a **shared utility** used by the parent KKW01021SFBean to dynamically load field metadata from nested typed-bean children in list-type UI components, enabling the screen framework to render per-field enable/disable and value state without hard-coding getters. It serves the broader **telecom customer contract management** domain - specifically the contractor/address information editing screen.

**CRITICAL - Constant Resolution:**

No external constants are referenced in this method. All field key strings are **hardcoded literals** (Japanese display labels). The `subkey` values are compared case-insensitively against three standard facets: `"value"`, `"enable"`, and `"state"`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The display-field label of a contractor/address field. Valid values are hardcoded Japanese labels: `"SYSID"` (System ID), `"CLIENT_NAME"` (Customer Name), `"CONTRACTOR_PREF"` (Contractor Prefecture Name), `"CONTRACTOR_CITY"` (Contractor City/Town Name), `"CONTRACTOR_DIST"` (Contractor District Alias Name), `"CONTRACTOR_CHOME"` (Contractor Chome/District Number Name), `"CONTRACTOR_LOT"` (Contractor Lot/Block Number), `"CONTRACTOR_BLDG"` (Contractor Address Supplement - Building Name), `"CONTRACTOR_ROOM"` (Contractor Address Supplement - Room Number), `"CONTRACTOR_PHONE"` (Contractor Phone Number). Determines which of the 11 contractor/address fields this call targets. |
| 2 | `subkey` | `String` | The property facet to retrieve for the specified field. Valid values: `"value"` returns the field's current data value, `"enable"` returns whether the field is editable (enabled/disabled flag), `"state"` returns the field's display state code. Case-insensitive comparison is used, so uppercase variants (e.g. "VALUE") are also accepted. |

**Instance fields read:** None directly - all data is delegated to getter methods on the bean itself (the 33 getter pairs described in Section 4). These getters internally read instance fields that hold the field values, enabled flags, and state codes for each contractor/address property.

**CRUD Summary:** This method performs **exclusively Read (R) operations**. Every called method is a getter on the same bean class that returns a property value, enabled flag, or display state for a contractor/address field. No service component (SC) calls, no CBS invocations, no database queries are made directly within this method. The data resides in the bean's instance fields.

| 1 | KKW01021SFBean | `KKW01021SFBean.loadModelData(key, subkey)` -> `KKW01021SF02DBean.loadModelData(key, subkey)` | `getSysid_value [R]`, `getCust_nm_value [R]`, `getKeisha_state_nm_value [R]`, `getKeisha_city_nm_value [R]`, `getKeisha_oaztsu_nm_value [R]`, `getKeisha_azcho_nm_value [R]`, `getKeisha_bnchigo_value [R]`, `getKeisha_adrttm_value [R]`, `getKeisha_adrrm_value [R]`, `getKeisha_telno_value [R]` |
| 2 | FUW00912SFBean (indirect) | Calls `loadModelData` on bean list items via `X33VDataTypeBeanInterface.loadModelData(key, subkey)` | Inherits same Read-only terminal operations through KKW01021SF02DBean |
| 3 | FUW00926SFBean (indirect) | Calls `loadModelData` on bean list items via `X33VDataTypeBeanInterface.loadModelData(keyElement, subkey)` | Same Read-only terminal operations through the bean chain |
| 4 | FUW00959SFBean (indirect) | Calls `loadModelData` on bean list items | Same Read-only terminal operations through the bean chain |
| 5 | FUW00964SFBean (indirect) | Calls `loadModelData` on bean list items via indexed bean access | Same Read-only terminal operations through the bean chain |

**Note:** The primary and direct caller is `KKW01021SFBean` within the same module. The KKW01021SFBean creates `KKW01021SF02DBean` instances and adds them to the `cust_list` DataTypeList (line 70 of KKW01021SFBean). Other modules (FUW*) that reference `loadModelData` are invoking it on their own bean hierarchies or on generic `X33VDataTypeBeanInterface` items - these are NOT direct calls to `KKW01021SF02DBean.loadModelData`, but rather invocations through the interface polymorphism chain.
