# Business Logic — FUW05401SFLogic.init() [149 LOC]

| Field | Value |

| Fully Qualified Name | `eo.web.webview.FUW05401SF.FUW05401SFLogic` |

## 1. Role

### FUW05401SFLogic.init()

This method is the **initial display processing entry point** for the K-Opticom eo optic telephone **option service subscription and cancellation** business logic module (FUW05401). It orchestrates the complete preparation of a customer-facing web screen where existing eo optic telephone contract holders can request additional option services (e.g., caller ID display, voicemail refusal, call detail delivery) or cancel existing ones. The method performs **screen data preparation** by retrieving and refreshing the current customer's contract information, fetching service interface data from backend SC components (FUSV0031 through FUSV0207), extracting transaction target records, performing initial-display error checks, running per-contract-record business validation (contract status, reservation processing, processing classification, promotion status), calculating applicable discount service codes, and configuring the next-screen navigation (either a pack-discount confirmation sub-screen FUW11001 or the appropriate subscription/confirmation/completion screen). It follows a **dispatch/delegation pattern**, calling multiple specialized helper methods for each distinct preparation phase — screen info retrieval, bean population, service invocation, data extraction, error checking, and navigation setup. The method always returns `true` (fixed), serving as a standard framework-mandated initializer in the BPM/web screen execution pipeline.

**Processing breakdown by phase:**

1. **Screen Info Inheritance (L535–L539)** — Retrieves the previous screen ID and processing classification from the session (inherited navigation context), and fetches the common info bean and service form bean for unified data access.

2. **Ronri Screen ID Acquisition (L543–L544)** — Extracts the abstract logical screen ID (e.g., `FUW054`, `FUW055`, `FUW056`, etc.) from the common info bean, which determines which specific option service screen variant is being displayed.

3. **Common Relation Check (L549–L551)** — Performs a cross-screen relation validation via `JFUWebCommon.checkCommonRelation(this, SVC_ID_INIT)`. The SSO log-in path (from `FUW05301_eo` electric phone customer contract information change / menu screen) sets NO_CHECK, so validation is intentionally skipped and processing proceeds here.

4. **Customer Contract Refresh (L552–L557)** — If the previous screen ID is not empty (i.e., navigation came from another internal screen rather than SSO entry), the current customer contract information is refreshed via `JFUWebCommon.refreshGenCustKei(this)`. If the from-screen-id is empty (SSO path), this step is skipped.

5. **Service Interface Parameters Setup (L562)** — Prepares the interface parameters for the core service component FUSV0031 by populating Ronri screen ID, service contract details, and system IDs from the beans.

6. **Service Contract Info Retrieval (L567)** — Extracts and sets the primary service contract information (service contract number, line details, phone number) from the common info bean into the service form bean.

7. **FUSV0031 Service Invocation (L572)** — Calls the core service layer via `callSvcFUSV0031`, passing the beans and retrieving an output map containing service results (price plans, service codes, contract records).

8. **Transaction Target Records Extraction (L577)** — Extracts the array of contract records that are eligible for transaction processing from the form bean.

9. **Initial Display Error Check (L582)** — Validates the current state of the contract data for initial display errors — checks for invalid contract states, conflicting records, or missing data that would prevent the screen from rendering correctly.

10. **Parent Contract Info Editing (L587)** — Processes and sets the parent contract information (parent service contract number, parent service contract internal details number) for hierarchical contract display.

11. **Variable Transaction Processing (L596–L598)** — For each target contract record, runs per-record transaction logic including: contract status determination, reservation processing check, processing classification determination (subscription/cancellation/change), and promotion status check. Returns a `kensuMap` with calculation results.

12. **Discount Service Code Acquisition (L602–L603)** — Retrieves the discount service code applicable after judgment processing. Used to determine if pack discount services apply.

13. **Various Judgment Processing (L608–L609)** — Executes various judgment logic including pricing validation, service eligibility checks, and promotional condition evaluation for each target record.

14. **Target Record Key Info Setup (L614–L615)** — Assembles and sets the key information for each processing target record for screen display.

15. **Call Charge Limit Amount Setup (L620–L621)** — Configures the call charge limit amount notification settings.

16. **Price Info Area Setup (L625–L628)** — Sets price information area data. Since paid/free services have different setup content, the free flag is set first and then the price information is configured afterward.

17. **Price Display Now Day Setup (L631)** — Sets the current date for price table display.

18. **Navigation Setup — Pack Screen Path (L635–L665)** — If a pack screen discount service code exists (non-null), the method configures inter-screen transfer information: resolves the option service code and sub-option service code via mapping maps (SBOP_SVC_CD_MAPPING_MAP / OP_SVC_CD_MAPPING_MAP based on ronriScreenId), creates a data map for pack processing, and sets the next screen to the pack confirmation sub-screen (`FUW11001`). Sets transfer page ID and next screen name/messages.

19. **Navigation Setup — Non-Pack Path (L667–L670)** — If no pack screen discount code exists, the next screen name is set directly via `getMskmScreenName` based on the ronri screen ID (subscription/confirmation/completion screen variant).

20. **Return (L673)** — Always returns `true` as a fixed value, indicating successful initialization.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0004 | `KKSV0004Flow.run()` -> `KKSV0004OPOperation.run()` -> `FUW05401SFLogic.init()` | `callSvcFUSV0031 [R] FUSV0031SC` |

**Notes on callers:**
- The method is invoked through the BPM framework's operation broker mechanism. `KKSV0004Flow` (a session EJB with mapped name "KKSV0004") dispatches to `KKSV0004OPOperation` via an `OperationBroker`. The operation class then delegates to `FUW05401SFLogic.init()` through the framework's standard web logic invocation pattern.
- Direct Java-level callers are absent because the method is called through the framework's reflection-based service invocation layer (`JCCWebBusinessLogic` base class mechanisms).
- The `KKSV0004OPOperation` is the dedicated operation class for the "eo optic telephone option service subscription/cancellation" screen (FUW05401) within the BPM flow.
- The logical screen ID (`FUW054` through `FUW103`) determines which specific option service variant (split phone, transfer phone, caller ID, voicemail, etc.) is processed.
