| Fully Qualified Name | `eo.web.webview.KKW01031SF.KKW01031SF01DBean` |

## 1. Role

### KKW01031SF01DBean.loadModelData()

This method serves as the central data-retrieval dispatcher for the KKW01031SF screen bean. It implements the X33 framework's `X33VDataTypeBeanInterface.loadModelData` contract, enabling the framework to resolve any field value on the bean by looking up a composite key string. In business terms, it provides uniform access to all seven data elements managed by this bean: the system ID (SYSID), the service contract number (サービス契約番号 — Service Contract Number), the transfer division code (異動区分 — Transfer/Modification Division), the transfer reason code list (異動理由コード — Transfer Reason Code), the transfer reason memo (異動理由メモ — Transfer Reason Memo), the application number (申請番号 — Application Number), and the application detail number (申請明細番号 — Application Detail Number). Each data item is dispatched to a getter method based on the `key` parameter, and the `subkey` parameter (typically `"value"` or `"state"`) determines whether the raw data value or the associated update-state flag is returned. The method acts as a read-only bridge between the X33 view framework's generic data-binding mechanism and the bean's strongly-typed domain fields. Notably, the Transfer Reason Code branch (`"異動理由コード"`) is a special indexed-list case: it supports retrieving the total count of list items when `subkey` is `"*"` via the `"key/"` prefix pattern, or fetching a specific list element's subfield via integer index delegation. This makes the method both a framework adapter and a domain data accessor for a service modification (異動 — Transfer/Modification) screen.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The business field identifier that specifies which data element to retrieve. It carries the name of one of seven managed fields: `"SYSID"` (system ID), `"サービス契約番号"` (Service Contract Number — the contracted service line identifier), `"異動区分"` (Transfer Division — the type/category of service modification), `"異動理由コード"` (Transfer Reason Code — a reason for the transfer, stored as an indexed list), `"異動理由メモ"` (Transfer Reason Memo — free-text reason description), `"申請番号"` (Application Number — the main application/requisition ID), or `"申請明細番号"` (Application Detail Number — the line-item detail ID within an application). For the Transfer Reason Code list item, the format is `"key/subkey"` with a slash separator to encode an array index. |
| 2 | `subkey` | `String` | A qualifier that determines what aspect of the identified field to return. For most fields, it is `"value"` (returns the raw string data) or `"state"` (returns the associated update-state flag). For the Transfer Reason Code list, `subkey` is ignored in the indexed-lookup branch and instead is forwarded to the individual list element's `loadModelData(subkey)` method. When `subkey` is `"*"`, the Transfer Reason Code branch returns the list size as an `Integer`. |

**Instance fields / external state read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `ido_rsn_cd_list` | `X33VDataTypeList` | The list of Transfer Reason Code items (X33VDataTypeStringBean elements), representing the set of all modification reasons selected or displayed on the screen. |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `getSysid_value` | KKW01031SF01DBean | - | Returns the system ID string value |
| R | `getSysid_state` | KKW01031SF01DBean | - | Returns the system ID update-state flag |
| R | `getSvc_kei_no_value` | KKW01031SF01DBean | - | Returns the service contract number string value |
| R | `getSvc_kei_no_state` | KKW01031SF01DBean | - | Returns the service contract number update-state flag |
| R | `getIdo_div_value` | KKW01031SF01DBean | - | Returns the transfer division code string value |
| R | `getIdo_div_state` | KKW01031SF01DBean | - | Returns the transfer division update-state flag |
| R | `getIdo_rsn_memo_value` | KKW01031SF01DBean | - | Returns the transfer reason memo string value |
| R | `getIdo_rsn_memo_state` | KKW01031SF01DBean | - | Returns the transfer reason memo update-state flag |
| R | `getMskm_no_value` | KKW01031SF01DBean | - | Returns the application number string value |
| R | `getMskm_no_state` | KKW01031SF01DBean | - | Returns the application number update-state flag |
| R | `getMskm_dtl_no_value` | KKW01031SF01DBean | - | Returns the application detail number string value |
| R | `getMskm_dtl_no_state` | KKW01031SF01DBean | - | Returns the application detail number update-state flag |
| R | `KKW01031SF01DBean.loadModelData` | KKW01031SF01DBean | - | Recursive delegation to an individual list element (X33VDataTypeStringBean) for Transfer Reason Code index lookup |
| R | `ido_rsn_cd_list.size` | KKW01031SF01DBean | - | Returns the count of items in the Transfer Reason Code list |

All operations are **Read** (R). This method is purely a data accessor — it does not write, create, update, or delete any data. It reads from instance fields (String values and state flags) and from the `ido_rsn_cd_list` data structure, acting as the single public read-entry point for the bean's data model.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Bean:KKW01031SFBean | `KKW01031SFBean` creates `KKW01031SF01DBean` instance; framework invokes `loadModelData` during X33 data-binding lifecycle | `getSysid_value [R] sysid_value field`, `getSvc_kei_no_value [R] svc_kei_no_value field`, `getIdo_div_value [R] ido_div_value field`, `getMskm_no_value [R] mskm_no_value field`, `getMskm_dtl_no_value [R] mskm_dtl_no_value field` |

**Notes:**
- The no-parameter overload `KKW01031SF01DBean.loadModelData()` (a separate method in the same class that likely delegates to the parent `X31CBaseBean.loadModelData()`) is the only direct caller referenced in the code graph. It likely serves as the framework's entry point when no key/subkey is supplied.
- The X33 framework's generic data-binding mechanism calls `loadModelData(key, subkey)` directly on this bean during view rendering and form submission processing.
- The parent bean `KKW01031SFBean` creates instances of `KKW01031SF01DBean` (see `KKW01031SFBean.java` lines 97, 1177, 1183) and the framework routes `loadModelData` calls through the list-bean interface to resolve nested element data.
