## 1. Role

### KKW01601SF03DBean.loadModelData()

This method serves as a **field routing and data dispatch** entry point for the `KKW01601SF03DBean` presentation bean. It implements a **bridge pattern** that maps from a human-readable field name (provided as a Japanese label string in the `key` parameter) and a sub-key `"value"` or `"state"` to the appropriate underlying data accessors — getter methods on the bean itself or recursive calls into nested bean objects inside list collections.

The method handles **two categories of data fields**: (1) **Simple fields** — single-value screen properties (e.g., System ID, Service Contract Number, Relocation Reason Memo, Location, Hostion Name) where it delegates to dedicated `getHktgi_*_value()` and `getHktgi_*_state()` getters. (2) **List (array) fields** — multi-value repeating items (Relocation Reason Code, Option Service Contract Number, Simultaneous Application Service Contract Number) where it parses an index from the `key` string, resolves it against the corresponding `List<X33VDataTypeStringBean>`, and recursively invokes `loadModelData()` on the nested bean element to retrieve the requested sub-property.

It acts as the **unified data access contract** for the screen, allowing callers to request any screen field by its display-label name without needing to know the internal field structure. This pattern is central to the bean-based view data binding architecture used across the KKA15301SF screen module, enabling template-driven page rendering and form editing.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The human-readable display label of a screen field. For simple fields it is the label itself (e.g., `"システムID"`). For list/array fields it carries a composite path: `"異動理由コード/INDEX"` where `INDEX` is a numeric index or `*` to request the list size. |
| 2 | `subkey` | `String` | The property accessor type — either `"value"` to retrieve the field's current data value, or `"state"` to retrieve its validation/processing state flag. |

**Instance fields read by this method:**

| Field Name | Type | Business Description |
|-----------|------|---------------------|
| `hktgi_ido_rsn_cd_list` | `List<X33VDataTypeStringBean>` | List of relocation reason codes — repeating multi-value field for reasons why a service contract is being transferred/changed |
| `hktgi_op_svc_kei_no_list` | `List<X33VDataTypeStringBean>` | List of option service contract numbers — repeating multi-value field for optional add-on services |
| `hktgi_mskm_svc_kei_no_list` | `List<X33VDataTypeStringBean>` | List of simultaneous application service contract numbers — repeating multi-value field for services applied in the same transaction |

All operations are **Read (R)** — this method only retrieves data. It never creates, updates, or deletes any records. No external SC Code (CBS/SC) or DB tables are directly invoked. The data originates from the bean's own fields, which are populated elsewhere in the screen lifecycle.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | KKW01601SF03DBean | `KKW01601SF03DBean.loadModelData` | `getHktgi_sysid_value [R]`, `getHktgi_svc_kei_no_value [R]`, `X33VDataTypeStringBean.loadModelData [R]` |

**Note:** The pre-computed code graph shows `KKW01601SF03DBean.loadModelData()` as its own direct caller (likely self-referencing via the recursive nested-bean call pattern). No external screens (KKSV*) directly invoke this method from the search results — it is a **protected internal utility** called by the bean's own lifecycle and by other methods within the same class that delegate to it for field access.

## 6. Per-Branch Detail Blocks

**Block 1** — IF `(key == null || subkey == null)` (L599)

> Null guard — if either parameter is null, return null immediately.

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return null;` // key or subkey is null |

**Block 2** — IF `(key.equals("システムID"))` (L610)

> Simple field: System ID. Dispatches based on subkey to the corresponding getter.
