## 1. Role

### FUW02001SFLogic.cfm()

This method is the confirm-button handler for the **Mail Address Setting Application** screen (FUW02001) in the K-Opticom customer billing system. It performs a comprehensive confirmation and submission process for a customer's request to set or change their email address for service notifications. Specifically, it validates that the re-entered email alias matches the originally entered value (preventing input errors), then invokes a batch of 15 downstream service component (SC) and coordination component (CC) operations covering ISP contract registration, optional service contract processing, ending target handling, and service order issuance. The method implements a **batch routing/dispatch pattern**: it reads the shared form bean and multiple contract information beans (SSO, billing contract, service contract, optional service contract, sub-optional service contract), prepares them into a unified parameter array, passes them through a mapper pipeline (FUSV0056_FUSV0056OPDBMapper), and finally invokes the centralized web service to commit the entire mail address setting application. It is a shared screen entry-point method called by the FUW02001 screen controller and navigates to screen FUW02002 (Mail Address Setting Application Confirmation) upon successful completion.

**CRITICAL -- Constant Resolution:**

The re-entry validation branch relies on these resolved constants:

| Constant | Resolved Value | Business Meaning |
|----------|---------------|-----------------|
| `FUW02001SFConst.RE_INPUT_MAILALIAS` | "メールアドレス（再入力）" | Re-entered mail alias field from the form |
| `FUW02001SFConst.MAILALIAS` | "メールアドレス" | Original mail alias field from the form |
| `X31CWebConst.DATABEAN_GET_VALUE` | "VALUE" | Data bean read mode |
| `X31CWebConst.DATABEAN_SET_VALUE` | "VALUE" | Data bean write mode |
| `X31CWebConst.TELEGRAM_INFO_USECASE_ID` | "usecaseId" | Parameter key for service use case ID |
| `USECASE_ID_FUSV0056` | "FUSV0056" | Mail Address Setting Application (Application) use case ID |
| `JPCModelConstant.FUNC_CD_2` | "2" | Function code for application processing |
| `JFUScreenConst.SCREEN_ID_FUW02002` | "FUW02002" | Next screen: Mail Address Setting Confirmation |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| - | (none) | - | This method takes no explicit parameters. It operates entirely on session-scoped form beans (shared form bean, service form bean) and instance fields inherited from the `JCCWebBusinessLogic` base class. |

**Instance fields and external state read:**

| Source | State / Field | Business Description |
|--------|--------------|---------------------|
| `super.getCommonInfoBean()` | Shared form bean | Contains shared customer session data including SSO info, billing contract info, service contract info, optional service contract info, and sub-optional service contract info |
| `super.getServiceFormBean()` | Service form bean | Contains the screen-specific input data (mail alias, re-entered mail alias, and other application form fields) |
| `this` (instance) | `MAIL_ALIAS_NOT_EQUAL_MSG`, `ERR_PLACE_PWD_RE_IN_MAILALIAS`, `CALL_METHOD_CFM` | Error message configuration and method context identifiers |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

The `cfm()` method invokes a linear pipeline of SC and CC operations through the `FUSV0056_FUSV0056OPDBMapper` mapper. Each SC operation prepares a data map that is chained through the sequence, with the output of one becoming the input of the next. The full batch is then committed via `invokeService()`.

| # | Operation | SC / CBS | SC Code | Entity / DB | Operation Description |
|---|-----------|----------|---------|-------------|----------------------|
| 1 | SC | `setFUSV005601SC` | FUSV005601SC | `EKK0011D020CBSMsg1List` (Order Content Admission) | Order content admission registration — reads customer contract data, sets ADD_CHG_DIV (registration/change split), maps SYSID and application details |
| 2 | SC | `setFUSV005602SC` | FUSV005602SC | `EKK0411D010CBSMsg` (Sub Optional Service Contract ISP) | Sub-optional service contract <ISP> registration — prepares ISP contract creation data |
| 3 | SC | `setFUSV005610SC` | FUSV005610SC | Sub-Optional Service Contract ISP | Sub-optional service contract <ISP> reference — retrieves existing ISP contract status for display/verification |

| 7 | SC | `setFUSV005606SC` | FUSV005606SC | `EZM0111C010CBSMsg` (End of Usage) | End-of-usage for ending target — identifies and registers services that should be terminated |
| 8 | SC | `setFUSV005607SC` | FUSV005607SC | `EZM0111D010CBSMsg` (Ending Registration) | Ending target registration — registers services designated for ending/disconnection |

| 13 | CC | `setFUSV005603CC` | FUSV005603CC | Service IF Result | Service IF result data transfer (part 1) — transfers intermediate service interface result data |
| 14 | CC | `setFUSV005604CC` | FUSV005604CC | Service IF Result | Service IF result data transfer (part 2) — transfers additional service interface result data, passing `this` context |
| 15 | CC | `setFUSV005605CC` | FUSV005605CC | Service Order | Service order issuance — generates the service order for the mail address setting application |

## 5. Dependency Trace

This method is the screen confirm-button handler for the **FUW02001** screen (Mail Address Setting Application). It is called by the screen dispatch framework based on the screen definition (not by other business logic classes). The `cfm` method does not appear to be invoked by any other method in the codebase — it is the entry point from the UI layer.
