## 1. Role

### KKW03204SFLogic.actionInit()

This method implements the **initial display processing** for the "050 Number Issuance Change" business module within K-Opticom's contract management system. The 050 Number Issuance Change module handles the cancellation, restoration, and reservation cancellation of telecommunication service numbers that have been issued under a customer contract.

The method performs **three key business operations**: (1) It retrieves screen context information from the framework and configures the service form DataBean with the operation service code `B029` (the code for the 050 Number Issuance Change service). (2) It branches on the `trans_div` processing division field to apply initialization logic specific to the operation type — calling `setDataInit_Kaiyaku()` when the processing division is DSL termination (`OP_TRAN_DIV_DSL = "04"`). (3) It routes message display based on `trans_div`, setting context-appropriate Japanese messages for termination, restoration, or reservation cancellation.

The method then delegates to the core business processing by invoking the **KKSV0135 initial display service** (`KKSV0135OP`) through `doService()`. It establishes bidirectional DataBean-to-Service mapping via the `KKSV0135_KKSV0135OPDBMapper` — pushing 6 service-item mappings (`setKKSV013501SC` through `setKKSV013506SC`) before the service call and pulling back 5 result mappings (`getKKSV013501SC` through `getKKSV013505SC`) if the service returns no error. Finally, it configures display date fields (`DSP_STAYMD`, `DSP_ENDYMD`) by retrieving their source values from the DataBean, with special handling for the service end date (`DSP_ENDYMD`) that resolves the reservation application date from the EKK1681B001CBSMsg1List data when available.

This method serves as the **screen entry point** for the 050 Number Issuance Change flow. It is invoked from parent screens (notably KKA16401SF which is the optional service contract list screen) and acts as a dispatch orchestrator that coordinates framework initialization, service item mapping, service invocation, and display DataBean preparation.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | `(none)` | - | This method takes no parameters. It reads state from instance fields and the framework bean. |
| - | `trans_div` | `String` (instance field) | Processing division code that determines the operation type. Valid values: `"01"` (RSV_CL — Reservation Cancellation), `"02"` (KAIHK — Restoration), `"04"` (DSL — Immediate Termination). Controls initialization branching and message selection. |
| - | `inputMap` | `HashMap<String, Object>` (instance field) | Map holding business data to pass to the AP server (service input). Populated with service item to DataBean mappings before service invocation. |
| - | `outputMap` | `HashMap<String, Object>` (instance field) | Map receiving business data from the AP server (service output). Used for pulling back DataBean mappings after service returns. |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Parent Screen: KKA16401SF (Optional Service Contract List) | `KKA16401SFLogic` -> framework navigation -> `KKW03204SFLogic.actionInit` | `KKSV0135OP [R] EKK1681B001CBS` |

**Notes on caller trace:** The `KKW03204SFLogic` class is a child logic class referenced by `KKA16401SFLogic` (the 050 Number Issuance Change parent screen). The parent screen delegates to this `actionInit()` method when the user navigates to the 050 Number Issuance Change initial display screen from the optional service contract list. No direct Java-level call references to `actionInit` were found in other screens — this method is the entry point for the KKW03204SF screen flow, invoked through the X31 web framework's navigation mechanism.
