| Fully Qualified Name | `eo.web.webview.FUW03501SF.FUW03501SFLogic` |

## 1. Role

### FUW03501SFLogic.init()

This method is the **entry-point initialization routine** for the **Dial-up Update Service Contract** screen (FUW03501) in the K-Opticom e-.Customer Core System. It orchestrates the complete setup of the screen's initial display state when a customer or agent first opens the service change screen. Specifically, it retrieves shared form data (common info and service detail beans), resolves the current operational service context (e.g., FTTH Authorization Registration), performs upper-mapping to populate pricing/plan/initial-cost data structures, calls the backend service `FUSV0073` (and `FUSV0074`) to fetch pricing plans, price courses, and dial-up-related check data, then performs **lower-mapping** to populate the service form bean with results.

The core business decision in this method is the **registration/change/view branching logic** based on the `chgDiv` (change division) field returned from the backend SC. When `chgDiv` is `"0"` (new registration), the screen initializes a fresh service change flow with the FTTH Auth Registration service code (`B020`). When `chgDiv` is `"1"` (change), the screen loads current contract details and allows the user to change their pricing plan. When `chgDiv` is `"2"` (view only), the user cannot make changes and is redirected to a billing screen (FUW03504).

The method implements a **routing/dispatch design pattern** — it collects all necessary data from shared context and the backend, then determines the next screen and sets screen flags (payable flag, mansion division flag) before returning `true` unconditionally. The screen ID is stored in the common info bean for downstream navigation.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:FUW03501 (Dial-up Update Service Contract) | `FUW03501SFChecker` -> `FUW03501SFLogic.init` | `invokeService [R] FUSV0073`, `getPcrsListBean`, `getPriceAreaBean` |

**Notes:** The `init()` method is the screen entry-point logic for the FUW03501 Dial-up Update Service Contract screen. The `FUW03501SFChecker` class references this logic class (line 37: "business logic class is FUW03501SFLogic"). No other classes were found calling `FUW03501SFLogic.init()` directly in the codebase. The method is invoked as the screen's initialization handler during the request processing flow.

### Block 3 — [CALL] Upper-mapping phase (L149-L156)

Performs upper-mapping to populate `dataMap` with pricing, cost, and plan data structures. This prepares the payload for the backend service call.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `dataMap = mapper.setFUSV007301SC(paramBean, dataMap, JPCModelConstant.FUNC_CD_1)` // Price plan list mapping |
| 2 | CALL | `dataMap = mapper.setFUSV007301CC(paramBean, dataMap)` // Initial cost CC |
| 3 | CALL | `dataMap = mapper.setFUSV007303SC(paramBean, dataMap, JPCModelConstant.FUNC_CD_2)` // Price course mapping |
| 4 | CALL | `dataMap = mapper.setFUSV007302CC(paramBean, dataMap)` // Dial-up related check CC |

### Block 4 — [CALL] Service invocation with error handling (L161-L172)

Invokes the backend service and handles web service exceptions by converting them to business exceptions.

| # | Type | Code |
|---|------|------|
| 1 | SET | `HashMap<Object, Object> outputMap = new HashMap<Object, Object>()` // Output result map |
| 2 | CALL | `invokeService(paramMap, dataMap, outputMap)` // Calls backend service FUSV0073 |

### Block 6 — [SET] Dial-up connection count handling (L182-L196)

Manages the dial-up update connection counts — setting, retrieving, and calculating remaining free connections.

| # | Type | Code |
|---|------|------|
| 1 | SET | `String nextScreenId = null` // Next screen ID (initially null) |
| 2 | SET | `String nextScreenName = null` // Next screen name (initially null) |

| 4 | SET | `int nowOpCnt = Integer.parseInt(bean.sendMessageString(DIAL_CONNECT_NOW_CNT, GET_VALUE))` // Parse current count |
| 5 | SET | `int muryoCnt = Integer.parseInt(bean.sendMessageString(DIAL_CONNECT_KEI_MURYO, GET_VALUE))` // Get free contract count |
| 6 | IF | `if (muryoCnt > 0)` // If there are free connections remaining |
| 6.1 | SET | `bean.sendMessageString(DIAL_CONNECT_KEI_MURYO, SET_VALUE, String.valueOf(muryoCnt - nowOpCnt))` // Set remaining free count |

### Block 7 — [IF/ELSE-IF/ELSE] Registration/Change/View branching (L198-L255)

**Core business branching logic** — determines the next screen and configuration based on the `chgDiv` (change division) returned from the backend SC.

**Block 7 — IF** `(CHG_DIV_0.equals(chgDiv))` — New Registration `[CHG_DIV_0 = "0"]` (L198)

> When `chgDiv` equals `"0"`, the customer is in a new registration flow. The screen initializes a fresh service change with the FTTH Auth Registration service code.

| # | Type | Code |

| 3 | SET | `nextScreenId = SCREEN_ID_FUW03501` // FUW03501 |
| 4 | SET | `nextScreenName = SCREEN_NAME_FUW03501` // Screen name for FUW03501 |

**Block 7.1 — ELSE** — Change/View `[CHG_DIV_0 != chgDiv]` (L204)

> When `chgDiv` is NOT `"0"`, the customer has an existing contract. Load current contract details and check if change is possible.

| # | Type | Code |
|---|------|------|
| 1 | SET | `bean.sendMessageString(CHG_DIV, SET_VALUE, TRK_DIV_HENKO)` // TRK_DIV_HENKO = "1" (Change) |
| 2 | SET | `bean.sendMessageString(NOW_PPLAN_STR, SET_VALUE, commoninfoMap.get(NOW_PPLAN_STR))` // Set current plan decision string |
| 3 | SET | `bean.sendMessageString(NOW_DIAL_NISHO_ID, SET_VALUE, commoninfoMap.get(NOW_DIAL_NISHO_ID))` // Set current authentication ID |
| 4 | SET | `bean.sendMessageString(AF_DIAL_NINSHO_ID_PWD, SET_VALUE, commoninfoMap.get(AF_DIAL_NINSHO_ID_PWD))` // Set post-application auth password |
| 5 | CALL | `setPplanName(bean, commoninfoMap, JPCModelConstant.FUNC_CD_1)` // Set current plan name |
| 6 | IF | `if (CHG_DIV_1.equals(chgDiv))` — Changeable `[CHG_DIV_1 = "1"]` |

**Block 7.1.1 — IF** `(CHG_DIV_1.equals(chgDiv))` — Changeable `[CHG_DIV_1 = "1"]` (L226)

> When `chgDiv` equals `"1"`, the customer can change their pricing plan. Allow plan selection and stay on the same screen.

| # | Type | Code |
|---|------|------|
| 1 | SET | `bean.sendMessageString(CHOICE_PPLAN_STR, SET_VALUE, commoninfoMap.get(NOW_PPLAN_STR))` // Set selected plan string |
| 2 | SET | `nextScreenId = SCREEN_ID_FUW03501` // Stay on FUW03501 |
| 3 | SET | `nextScreenName = SCREEN_NAME_FUW03501` |

**Block 7.1.2 — ELSE-IF** `(CHG_DIV_2.equals(chgDiv))` — View Only `[CHG_DIV_2 = "2"]` (L234)

> When `chgDiv` equals `"2"`, the customer cannot make changes (view only). Redirect to the billing screen with add-on screen suffix.

| # | Type | Code |
|---|------|------|
| 1 | SET | `nextScreenId = SCREEN_ID_FUW03504` // FUW03504 (Billing screen) |
| 2 | SET | `nextScreenName = SCREEN_NAME_FUW03504` |
| 3 | CALL | `super.setTransferPageId(SCREEN_ID_FUW03504 + "0PJP")` // WARIKOMI_GAMEN_ID_FUKA_STR = "0PJP" |

### Block 8 — [CALL] Flag setting (L257-L260)

Sets the payable flag and mansion division flag based on the output data and common info.

| # | Type | Code |
