## 1. Role

### JKKTvSvcKeiCancelCC.svcCancel()

This method performs the complete **Service Contract Cancellation** (サービス契約キャンセル) flow for a TV service contract. It is the core business logic coordinator that cascades cancellation requests across multiple layers of the service contract hierarchy: the top-level service contract, its detail lines, associated option service contracts, equipment-provided service contracts (for equipment rental services), and service contract line details. It also handles the cancellation of the underlying pending applications (申込) and, in specific statuses, cancels associated work orders (工事案件).

The method implements a **cascade/crawl design pattern**: it queries child entities in a hierarchical tree (service contract -> detail lines -> equipment-provided contracts), applies status-based filtering to skip already-cancelled or disconnected lines, and invokes the appropriate CBS-level cancellation for each valid child before proceeding deeper. All cancellations use a common reason code ("01" -- general cancellation) and a shared move category (ido_div).

Its **role in the larger system** is as a shared CBS-level handler. It is called from the `cancel()` method of the same class, which is the entry point invoked by the screen CBS (e.g., `KKSV0004` for TV service contract cancellation screens). The method returns the final updated timestamp (lastUpdDtm) which is used by the caller for optimistic concurrency control across the overall cancellation flow.

The method handles four distinct processing branches based on the service contract status (`curSvcKeiStat`): **status "020" (Confirmed/照映済)** — where it additionally checks for pending applications and may cancel the entire application or individual details; **status "010" (Received/受付済)** — where it cancels pending application details but does not check the application level; equipment-provided service contract cancellation for V-ONU equipment in the service line detail path; and **work order cancellation (EKU0091C010)** when the contract is confirmed with an active work order.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `handle` | `SessionHandle` | Database/session handle for executing CBS (service component) calls. Carries transaction context and database connection state. |
| 2 | `scCall` | `ServiceComponentRequestInvoker` | Service Component invocation router. Used by `callSC()` to dispatch CBS requests (EKK0081C160, EKK0161B004, etc.) to the appropriate backend CBS handler. |
| 3 | `param` | `IRequestParameterReadWrite` | Request parameter object carrying the data map (`ccMsg`) containing all business data extracted from the screen/form input, including `func_code`, `ido_div`, `svc_kei_no`, `mskm_lastUpdDtm`, `sysid`, `kojiak_no`, and `kojiak_stat`. |
| 4 | `dataMapKey` | `String` | Key within the request parameter to locate the data map (`ccMsg`). Equivalent to `fixedText` — ties this call to a specific data context/screen. |
| 5 | `mskmNo` | `String` | Application number (申込番号) — the top-level application/subscription ID. Used when checking pending application details at the bottom of the method (for status "010"). |
| 6 | `mskmDtlNo` | `String` | Application detail number (申込明細番号) — identifies which specific line-item within the application is being cancelled. Skipped in application-level status checks to avoid cancelling itself. |
| 7 | `lastUpdDtm` | `String` | Last update timestamp (最終更新年月日時分秒) — carries forward optimistic concurrency control across the cascade of CBS calls. Each cancellation updates it. Starts from the caller; is updated by each CBS response. |
| 8 | `curSvcKeiStat` | `String` | Current service contract status (サービス契約ステータス). Drives the processing branch: "010" = Received (受付済), "020" = Confirmed (照映済). Also affects whether pending applications and work orders are cancelled. |

**Instance fields read:** None directly in `svcCancel`. Template IDs (`TEMPLATE_ID_*`) are class-level static constants resolved at compile time.

|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `cancel()` in JKKTvSvcKeiCancelCC | `cancel()` -> `svcCancel(handle, scCall, param, dataMapKey, mskmNo, mskmDtlNo, lastUpdDtm, curSvcKeiStat)` | `EKK0081C160 [U] KK_T_SVC_KEI`, `EKK0161C160 [U] KK_T_SVC_KEI_UCWK`, `EKK0341C330 [U] KK_T_KKTK_SVC_KEI`, `EKK0351C220 [U] KK_T_OP_SVC_KEI`, `EKK0251C070 [U] KK_T_SVC_KEI_KAISEN_UCWK`, `EKK0011C060 [U] KK_T_MSKM`, `EKK0021C070 [U] KK_T_MSKM_DTL`, `EKU0091C010 [U] KK_T_KOJIAK` |

**Details:** The `cancel()` method in the same class (`JKKTvSvcKeiCancelCC`) is the direct caller. It performs preparatory steps (retrieving service contract info via EKK0081A010, fetching application numbers via `execMskm()`, determining mskmNo/mskmDtlNo based on status), then delegates to `svcCancel()`. After `svcCancel()` returns, `cancel()` continues with `execWrisvcAutoAply()`, `registProgressInfo()`, and optional customer withdrawal processing. The terminal operations from `svcCancel` include 11 unique CBS codes: EKK0081C160, EKK0161B004, EKK0161C160, EKK0341B501, EKK0341C330, EKK0351B002, EKK0351C220, EKK0241B001, EKK0341B504, EKK0081B035, EKK0251C070, EKK0011B020, EKK0011C060, EKK0021C070, and EKU0091C010.
