## 1. Role

### JKKAdchgCancelHakkoSODCC.cancel()

The `cancel` method orchestrates the **cancellation of Service Order Data (SOD)** issued during address change (Jusho Henkou) processing in the K-Opticom telecommunications customer base system. When a customer changes their registered address, the system may have previously issued Service Orders (SOD) for associated services such as FTTH broadband, landline telephone, or optional add-ons. This method reverses those issued orders by iterating through each service contract item and dispatching the appropriate cancellation SOD generation logic.

It handles **two primary service types**: FTTH (Fiber To The Home, code "1") and landline telephone (code "2"), routing each to dedicated cancellation handlers (`hakkoSODNet` for fiber-optic services and `hakkoSODTel` for telephony). Services outside these types (mobile, ADSL, etc.) are silently skipped.

The method implements the **routing/dispatch pattern**: it evaluates each service contract type via `svcKeiJdg`, then delegates to the correct handler. It also enforces **resource management** by holding the session handle in a ThreadLocal during processing and releasing it in a finally block.

As a **shared utility** component (CC = Common Component), it is called by multiple screen operations (KKSV0725, KKSV0729) that process address change workflows. It is not an entry point itself, but rather a reusable business service that processes the cancellation of SOD for all service types listed in the input. The method returns early with a success status (code "0000") if no service contracts are present, treating that as an empty-valid case.

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| CALL | `JKKAdchgCancelHakkoSODCC.svcKeiJdg` | - | - | Determines service type of each service contract item — returns service kind code (NET="1", TEL="2", etc.) |
| CALL | `JKKAdchgCancelHakkoSODCC.hakkoSODNet` | - | - | Generates cancellation SOD for FTTH (fiber-optic) broadband services |
| CALL | `JKKAdchgCancelHakkoSODCC.hakkoSODTel` | - | - | Generates cancellation SOD for landline telephone services |
| CALL | `JKKAdchgCancelHakkoSODCC.isBlank` | - | - | Utility check whether a String is null or blank |
| R | `JCMAPLConstMgr.getString` | JCMAPLConstMgr | - | Retrieves localized status message by return code key (e.g., "RETURN_MESSAGE_0000") |

**Note:** The `hakkoSODNet` and `hakkoSODTel` methods contain the actual service component (SC) and CBS (Common Business Service) calls that perform the terminal CRUD operations. Those methods are not analyzed here because they are delegated calls handled in separate methods of the same class. The `cancel` method itself is a **control-plane coordinator** — it iterates, judges, and dispatches, without directly performing any database operations.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0725 | `KKSV0725OPOperation` -> `CCRequestBroker target81` -> `JKKAdchgCancelHakkoSODCC.cancel` | `hakkoSODNet [C] cancellation SOD generation`, `hakkoSODTel [C] cancellation SOD generation` |
| 2 | Screen:KKSV0729 | `KKSV0729OPOperation` -> `CCRequestBroker target6e` -> `JKKAdchgCancelHakkoSODCC.cancel` | `hakkoSODNet [C] cancellation SOD generation`, `hakkoSODTel [C] cancellation SOD generation` |

**Caller Details:**

1. **KKSV0725OPOperation** — Address change screen operation. Uses `CCRequestBroker target81` to invoke the `cancel` method through the mapping class `KKSV0725306CC`. This screen handles FTTH address change workflows where issued SOD must be cancelled upon address change.

2. **KKSV0729OPOperation** — Another address change screen operation. Uses `CCRequestBroker target6e` to invoke the `cancel` method through the mapping class `KKSV072960CC`. This screen also handles address change processing including SOD cancellation.

Both callers invoke `cancel` as part of a broader address change (Jusho Henkou) workflow where the system must reverse any previously issued Service Orders.
