## 1. Role

### KKW03201SFLogic.actionInitKKW03201()

This method performs the **initial display processing for the 050 Number Issuance Registration screen** (登録画面初期表示処理(画面ごと個別処理） — "Screen initialization processing (per-screen specific processing)"). It is the dedicated entry point invoked when the screen dispatcher identifies screen ID `KKW03201`, which corresponds to the 050 (050番) number issuance registration feature within the customer contract management system of K-Opticom.

The method implements a **builder pattern** for preparing all data required by the 050 Number Registration form on initial load. It orchestrates several sub-tasks: retrieving and setting the current operating date for reservation applicability, mapping screen DataBeans to service parameters via the `KKSV0099_KKSV0099OPDBMapper`, invoking a backend service (screen BP 050) to fetch initial data, building pulldown list options for display, parsing and decomposing date values into year/month/day components for form binding, and transferring generational registration datetime fields between data bean hierarchies. The method uses a **delegation pattern**, routing DataBean access, mapping, and logging through framework classes.

The screen serves the business domain of issuing new 050 numbers (K-Opticom's virtual number service) — enabling operators to register customers with a 050-number service contract, including reservation dates, service agreements, option service consent, and generational subscription data. The method always returns `true` on normal completion (正常終了), and `false` only if an exception is thrown and propagated (異常終了).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | This method takes no parameters. It operates entirely on instance-level state and the framework's DataBean infrastructure. |

**External state / instance fields read:**

| Source | Accessor | Business Description |
|--------|----------|---------------------|
| `super` | `getServiceFormBean()` | Retrieves the service form DataBean (`X31SDataBeanAccess`) — the primary form model that holds all screen input/output data for the current request session. |
| `super` | `getSessionData(X31SDataBeanAccess)` | Populates the DataBean with session-stored values — loads previously entered or cached screen state from the HTTP session. |
| `super` | `getCommonInfoBean()` | Retrieves the common info DataBean used to set cross-screen metadata like the next screen identifier. |
| `this` | `dumpDatabean()` | Internal debugging helper that serializes the current DataBean state for logging. |
| `this` | `invokeService(...)` | Inherited from `JCCWebBusinessLogic` — dispatches to the backend CBS service using the prepared parameter/telegram maps. |

## 5. Dependency Trace

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

No screen/batch entry points found within 8 hops. Direct callers found: 1 methods.
Terminal operations from this method: `getOpeDate` [R], `getSessionData` [R], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `getDataBean` [R], `getDataBean` [R], `getDataBeanArray` [R], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `sendMessageString` [-], `getDataBean` [R], `getDataBean` [R], `getDataBean` [R]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `KKW03201SFLogic.actionInit()` | `actionInit()` -> screensId check (`JKKScreenConst.SCREEN_ID_KKW03201`) -> `actionInitKKW03201()` | `invokeService` [R] KKSV0099 BP 050; `setPulldownList` [-] HRADSI_SBT_LIST; `getOpeDate` [R] operating date |

The method is only ever called from `KKW03201SFLogic.actionInit()`, which serves as the screen dispatcher. The dispatcher reads the screen ID from the common info DataBean (`NEXT_SCREEN_ID`) and routes to the per-screen init handler. When the screen ID matches `KKW03201`, `actionInitKKW03201()` is invoked.

The terminal operations reachable from this method include:
- `invokeService` -> calls the BP 050 Number Issuance Registration Initial Display service, which in turn calls downstream CBS components mapped by the `KKSV0099` mapper.
- `getOpeDate` [R] -> reads the current operating date from the system date configuration.
- `getSessionData` [R] -> reads session-stored screen state.
- `sendMessageString` / `getDataBean` / `getDataBeanArray` [R/-] -> DataBean framework accessors for form field I/O.
