## 1. Role

### FUW02701SFLogic.init()

This method is the **initial processing entry point** for the **Web Contract Capacity Addition Application** (Web契約容量追加申込) screen (FUW027010PJP) in the K-Opticom customer management system. It serves as the bootstrapping logic that prepares all display data for the capacity addition screen, which allows existing customers to add bandwidth capacity to their existing fiber-to-the-home (FTTH) web contract.

The method implements a **screen initialization and data enrichment pattern**. It retrieves the customer's current service contract information from shared form beans (including SSO info, service contract info, option service contract info, and sub-option service contract info), validates the service data, and then invokes a series of service component (SC) calls through the `FUSV0076` service — specifically for displaying business parameter management (MY portal protocol), fee coding for sub-option services, price plan fixed unit pricing (option application fees), and additional charges. An initial fees display component class (CC) call follows to compute the initial cost summary.

The method's **role in the larger system** is as the screen entry point for the first of a three-screen flow: (1) FUW027010PJP — initial display screen where customers view available capacity and pricing; (2) FUW027020PJP — confirmation screen where they review the addition details; and (3) FUW027030PJP — completion screen. It validates that the customer has a positive remaining addable capacity (`webKeiCapa > 0`), throwing a "contract already exhausted" error (`ERROR_CODE_0103`) if no capacity remains. It also determines whether the customer is a new registration or a change (modifying existing capacity), sets mansion-specific flags, applies payment flags, and configures mapping for the price display area.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen: FUW027010PJP (Initial Display) | `WEBGAMEN_FUW027010PJP.xml` -> `<BL id="FUW02701SF">` -> `FUW02701SFLogic.init()` | `setFUSV007601SC [R]`, `setFUSV007602SC [R]`, `setFUSV007603SC [R]`, `setFUSV007604SC [R]`, `setFUSV007601CC [R]`, `invokeService [C] FUSV0076` |
| 2 | Screen: FUW027020PJP (Confirmation) | `WEBGAMEN_FUW027020PJP.xml` -> `<BL id="FUW02701SF">` -> `FUW02701SFLogic.init()` | Same as above (shared BL definition) |
| 3 | Screen: FUW027030PJP (Completion) | `WEBGAMEN_FUW027030PJP.xml` -> `<BL id="FUW02701SF">` -> `FUW02701SFLogic.init()` | Same as above (shared BL definition) |

**Notes:** The `FUW02701SF` business logic (BL) definition is shared across all three screens (initial display, confirmation, and completion) via the `<BL id="FUW02701SF">` element in each screen's XML definition. The framework routing dispatches to `FUW02701SFLogic.init()` as the initial screen processing. The `cfm()` method in the same class handles the confirmation button press path (which calls `FUSV0077` instead).
