## 1. Role

### FUW03901SFLogic.mskm()

This method is the **confirm-screen submit handler** (the "Apply" button processing) for the **Authentication ID and Password Change** screen in the K-Opticom customer management system. It orchestrates the full end-to-end submission of a customer's request to change their ISP authentication ID and password. The method first validates the contract state by checking that the current authentication ID is set, then performs a single-linkage (tankanren) check that validates password consistency — ensuring the current password is correct, the new password matches its re-entry, and the new password differs from the old one. If validation fails, it returns early with error messages. Upon successful validation, it branches by service group code (`prcGrpCd`): for standard non-ADSL services, it invokes a comprehensive 12-step mapping sequence through the `FUSV0075_FUSV0075OPDBMapper` covering authentication ID/password verification, application content approval registration, ISP authentication ID password change, progress registration, application detail inquiry, service IF data transfer, and order issuance; for eoADSL (Fres) services, it invokes a streamlined 1-step mapping through `FUSV0259_FUSV0259OPDBMapper` for ADSL-specific authentication ID password change. Finally, it routes the user to the FUW03902 confirmation completion screen. This method implements the **delegation** and **routing/dispatch** design patterns, acting as the central coordination point that aggregates data from shared and service form beans, delegates to a mapper for T-Map data mapping, and invokes the BP (dialect API) service layer for downstream processing.

**Block descriptions:**

1. **Common Relation Check** — Calls `JFUWebCommon.checkCommonRelation()` for front-line common product / common linkage validation with `USECASE_ID_FUSV0075`.
2. **Bean Retrieval** — Acquires the common info bean and service form bean from the session.
3. **Shared Home Bean Data Extraction** — Extracts nested bean structures: Web Change Info, SSO Info, and Current Customer Info from the shared home bean hierarchy.
4. **Authentication ID Presence Check** — Verifies the current authentication ID (`NOW_NINSHO_ID`) is set on the bean. If missing, throws contract state error (0102).
5. **Single-Linkage (Password) Check** — Delegates to `tankanrenCheck()` for comprehensive password validation (current password match against SSO, new password consistency, password change verification). If validation fails, returns `true` with an error message displayed.
6. **Parameter Array Construction** — Assembles three bean arrays (`paramBean1`, `paramBean2`, `paramBean3`) with varying levels of data scope for different mapper calls.
7. **Service Group Code Extraction** — Extracts the price group code (`prcGrpCd`) from the service contract info to determine the service type branch.
8. **Branch: Non-eoADSL (Fres) vs eoADSL** — If `prcGrpCd` equals `CD00133_06` ("06"), it is an eoADSL (Fres) service path; otherwise, it is the standard non-ADSL path.
9. **Standard Path (Non-eoADSL)** — Creates `FUSV0075_FUSV0075OPDBMapper` and executes 12 sequential mapping operations covering password existence check, ID list matching, password authentication list matching, application content approval registration, ISP credential change, progress registration, application detail inquiry, 3x service IF data transfers, and order issuance.
10. **ADSL Path (eoADSL/Fres)** — Creates `FUSV0259_FUSV0259OPDBMapper` and executes a single mapping operation (`setFUSV025901CC`) for ADSL-specific authentication ID password change.
11. **Service Invocation** — Calls `invokeService()` with the populated parameter map, data map, and output map. Handles `JCCWebServiceException` with detailed error classification based on template ID, error flag, and item ID.
12. **Navigation Routing** — Sets the next screen ID and name to `FUW03902` on the common info bean and returns `true`.

**How to classify:**

- **C** (Create): Methods with names like `executeOdrHakkoJokenAdd()` — application content approval registration, progress registration.
- **R** (Read): Methods with names like `getStatus()`, `getDataBean()`, `sendMessageString()` with `DATABEAN_GET_VALUE` — all data retrieval operations from beans and status checks.
- **U** (Update): Methods like `setFUSV0075xxSC` that write data to mapped output structures; `setMessageInfo()` for setting error messages.
- **D** (Delete): Not present in this method.

**How to find SC Code:**
- SC codes follow the pattern `FUSV007501CC`, `FUSV007501SC`, etc. — the `FUSV0075` prefix identifies the service component for authentication ID/password change, and the suffix (`01`, `02`, `03`, `04`, `05`, `06`, `07`) identifies the specific operation.
- For the eoADSL path: `FUSV025901CC`.

**How to find Entity/DB tables:**
- The mapper classes (`FUSV0075_FUSV0075OPDBMapper`, `FUSV0259_FUSV0259OPDBMapper`) map to BP (dialect API) components which in turn interact with database tables. The actual table names (e.g., `KK_T_ODR_HAKKO_JOKEN`, `KK_T_SVC_KEI`, `KK_T_SVC_KEI_UCWK`) are resolved within the called SC/CBS methods.

**Notes:**
- No external callers to `mskm()` were found in the codebase. This method is the direct submit handler for the FUW03901 confirm screen, typically invoked through the framework's screen-to-logic routing.
- The `USECASE_ID_FUSV0075` constant (`"FUSV0075"`) is passed to `checkCommonRelation()` and `invokeService()` to identify the service use case.
- The eoADSL (Fres) variant uses `USECASE_ID_FUSV0259` (`"FUSV0259"`).
