## 1. Role

### KKW00128SFLogic.cfmTbxKKW00128SFBean()

This method populates the service form bean for the **Service Contract Information Update Confirmation (eo Hikari Net)** screen. It serves as the **data assembly step** during a "re-display" (再表示) operation, where the system retrieves all relevant service contract, contract details, line details, and address data from the submission-side data beans and consolidates them into the display-side form bean so the user can review their changes. The method handles **four major data consolidation domains**: (1) Service contract header information (review result code, case number, remarks, last update timestamp), (2) Service contract detail information (contract detail number, last update timestamp), (3) Service contract line detail information (line detail number, postal code, phone number, billing room number, full address, expected installation date), and (4) Service lifecycle dates (start date, end date, charge end date, stop/suspension dates, pause dates) along with business flags (unconfirmed address flag, HGW replacement impossibility flag, district reorganization flag, internet opt-out flag, legal entity contract succession flag, WAO integration availability). It uses a **data copy/translation pattern** — pulling values from source data beans by a "_suffix" key pattern (e.g., `_03`, `_04`, `_07`) and writing them to the target form bean using the canonical key name. Date fields are concatenated from year/month/day components and formatted for display. The method also applies conditional logic: copying service end date to service charge end date when `ido_div == "00005"` (termination separation case), and computing WAO (Wired Access Office) integration availability based on whether a Netflix pack change is in progress.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `svcFormBean` | `X31SDataBeanAccess` | The main form data bean that carries all screen display fields for the Service Contract Update Confirmation (eo Hikari Net) screen. It contains both the source data (submitted values from the previous step, keyed with suffixes like `_03`, `_04`, `_07`) and the target display fields (canonical keys without suffix). This bean is populated by this method so the screen can render all confirmed data. |

**Instance fields read by this method:**

| Field | Type | Business Description |
|-------|------|---------------------|
| `ido_div` | `String` | Disconnection separation flag — when equal to `"00005"`, indicates a termination separation case where service charge end dates must be copied from service end dates |
| `sysid` | `String` | System ID |
