## 1. Role

### KKW02404SFLogic.actionInit()

This method serves as the **initial display processing** entry point for the KKW02404SF screen, which handles **option service contract status management** in a telecom service provisioning system. Its primary responsibility is to prepare the screen state on first load by orchestrating a series of initialization steps: retrieving the screen context, fetching the service form DataBean, setting up header/transmit data beans, invoking the core service initialization logic, and then mapping the service results back to the DataBean.

The method's most significant business role is **conditional message routing and write-protection based on the transaction division and service status**. After completing the initialization pipeline, the method inspects the current `trandiv` (process division) and `op_svc_kei_stat` (option service contract status) to determine how to behave:

- **DSL Cancellation branch** (`trandiv = "04"`): If the option service status is one of the valid operational states (connection completed, service providing, or suspended/interrupted), the screen allows normal updates. Otherwise, it displays an error message and disables the update flag.
- **Restoration branch** (`trandiv = "05"`): If the service status is "contract canceled" (`"910"`), a specific restoration message is displayed. Otherwise, the screen is locked with an error and the update flag is disabled.
- **Reservation Cancellation branch** (`trandiv = "06"`): If the service status is one of the pre-fulfillment states (received, under review, connection completed, or service providing), a reservation cancellation confirmation message is shown. Otherwise, the screen is locked.

The method follows a **facade pattern** — it presents a single clean entry point that delegates to multiple internal helper methods (`setHktgiBean`, `executeInitSvc`, `setDataInit`) while also performing post-initialization guard logic. It is a **shared screen logic class** used by the KKW02404SF checker and called from the screen controller entry flow.

**Block Processing Sequence:**

1. **Screen Info Retrieval (L83)** — Call `JCCWebCommon.getScreenInfo(this)` to fetch the screen context from the framework. (Japanese: 画面情報を取得し、サービスフォームBeanに設定。 — "Retrieve screen information and set in service form Bean.")
2. **DataBean Acquisition (L85-86)** — Retrieve the `X31SDataBeanAccess` service form bean from the parent class and wrap it in an array `paramBean` for pass-by-reference to helper methods.
3. **Message Info Array (L89)** — Allocate `String[] msgInfo` for use as a message content buffer in downstream branches.
4. **Header/Transmit Bean Setup (L92)** — Call `setHktgiBean(paramBean)` to configure header and transmit bean data. (Japanese: DataBean設定処理（情報） — "DataBean setting processing (inheritance information).")
5. **Service Initialization (L95)** — Call `executeInitSvc(paramBean)` to execute the core service initialization logic. (Japanese: 初期表示サービス呼び出し処理 — "Initial display service call processing.")
6. **DataBean Post-Processing (L98)** — Call `setDataInit(paramBean)` to map service results back to the DataBean. (Japanese: DataBean設定処理(サービスの呼び出し結果を設定) — "DataBean setting processing (set service call results).")
7. **Runtime State Extraction (L101-102)** — Read the `trandiv` (process division) and `op_svc_kei_stat` (option service contract status) values from the DataBean using `sendMessageString` with `DATABEAN_GET_VALUE` mode.
8. **Conditional Routing (L105–L168)** — Three mutually exclusive branches based on `trandiv` value, each performing status-dependent message display or write-lock logic.
9. **Debug Logging (L171)** — Dump the current DataBean state to the log via `JSYwebLog.println`.
10. **Return (L173)** — Return `true` indicating successful initialization.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKW02404SF | Screen Controller -> `KKW02404SFLogic.actionInit` | `getScreenInfo [R] ScreenConfig`, `sendMessageString [R] DataBean` |
| 2 | Checker:KKW02404SFChecker | `KKW02404SFChecker` validates output of `KKW02404SFLogic.actionInit` | `setMessageInfo [-] MessageFramework` |

**Notes on callers:**

- **KKW02404SF Screen**: This is the primary screen controller that invokes `actionInit()` during the screen initialization phase. The screen ID follows the `KKSV*` naming convention (screen logic class is `KKW02404SFLogic`).
- **KKW02404SFChecker**: A business logic checker class for KKW02404SF (found in both `koptWebA` and `koptWebB` modules) that references `KKW02404SFLogic` as its target business logic class. The checker is invoked after `actionInit()` completes to validate screen data.
- No external callers outside the `KKW02404SF` module were found. This method is a **private-to-module screen entry point**.
