| Fully Qualified Name | `eo.web.webview.FUW02001SF.FUW02001SFLogic` |

| Module | `FUW02001SF` (Package: `eo.web.webview.FUW02001SF`) |

## 1. Role

### FUW02001SFLogic.mskm()

This method is the core business logic handler invoked when a customer presses the **「Apply」button (申し込むボタン)** on the **confirmation screen** for the **Email Alias Setup Registration** (メールエイリアス設定申込) service. The screen module `FUW02001SF` belongs to the K-Opticom customer backbone system (eo顧客基幹システム) and is responsible for fiber-optic broadband subscription workflows.

The method processes a complete **apply-for-email-alias** order, which encompasses **SubOptional Service Contract** operations including registration, lookup, binding, start of usage, changes, and supplementary tasks. It orchestrates a batch of **Service Component (SC)** calls mapped through `FUSV0056_FUSV0056OPDBMapper` — 9 SCs for CRUD operations on ISP service contracts, and 5 **Common Component (CC)** calls for consent checks, email alias validation, service IF data transfer, and service order issuance.

The method acts as the **entry point for the apply (submit) operation** within the Email Alias Setup Registration confirmation workflow. After gathering all customer and contract data from common info beans, building parameter maps, invoking the downstream service pipeline via `invokeService`, and refreshing the general customer contract, it transfers resulting email alias data back to the form bean. Finally, it routes the user to the completion screen `FUW02003` and sends a completion email — choosing between an **addition completion email** (for new registrations) or a **change completion email** (for modifications) based on the `ADD_CHG_DIV` value.

**Notes:**
- This method is the **apply button handler** (`call_method` = "mskm") on the **FUW02001 confirmation screen**.
- It is the terminal entry point within the `FUW02001SF` logic module — no other classes invoke `mskm()` directly from external screens.
- The caller is the FUW02001 screen's controller/boundary class, which dispatches to this method based on the button pressed (cfm = confirm, mskm = apply).
- After this method returns `true`, the screen framework navigates to screen `FUW02003` (completion screen).
