## 1. Role

### JKKTvSvcKeiCancelCC.cancel()

This method orchestrates the complete cancellation workflow for a K-Opticom TV service contract line (service detail: `svc_kei`). It is the central business controller that coordinates multiple service components (SCs) and custom components (CCs) to perform a full TV contract cancellation — including state verification, order detail lookup, service contract cancellation execution, discount auto-application, progress tracking, and conditional post-cancellation processing such as customer de-registration and instruction letter issuance.

The method implements a **delegation pattern** with **conditional dispatch** based on the current service contract status. When the contract is in the "confirmed" state (`020`), it branches to search for the associated order details (`execMskm`) before proceeding. When the contract is already in a non-confirmed state (e.g., accepted), it reuses the existing order number from the incoming parameter map. This allows the method to handle both freshly confirmed orders and pre-existing accepted orders in a single entry point.

Additional conditional branches handle business-specific post-cancellation actions: if the contract was confirmed and the movement type is NOT a "relocation/registration" (`ido_div != "00019"`), it triggers the customer common cancellation component (`callCusTaikaiCmnKino`). If an ID notification letter has NOT yet been issued (`ID_TCHISHO_HAK_SKBT_CD != "0"`), it delegates to the instruction letter registration component (`JKKTVSjishoAddCC.mainExecute`). The method serves as a shared utility component called by multiple TV service screens (KKSV0484 and KKSV0729), making it a critical cross-cutting cancellation handler in the eo TV customer core system.

**Processing Steps Explained:**

1. **Initialization**: The method extracts a data map key from the `fixedText` parameter, retrieves the central message map (`ccMsg`) from the request parameter, and extracts the last update datetime stamp. A `ServiceComponentRequestInvoker` is instantiated for SC communication, and the current operation date is fetched.

2. **Service Contract Consultation (EKK0081A010)**: An inquiry is made to retrieve the current state of the service contract line. FUNC_CODE `"2"` indicates a consultation (inquiry) operation. The method extracts the current service contract status (`curSvcKeiStat`) from the response.

3. **Conditional Branch — Order Detail Search**: If the contract status is `"020"` (Confirmed / 照併済), the method calls `execMskm` to search for and register the order details, extracting both the order number (`mskmNo`) and detail number (`mskmDtlNo`). Otherwise (the contract is already in a non-confirmed state, e.g., Accepted), it reuses the pre-existing order number from the parameter map.

4. **Core Cancellation (svcCancel)**: The main service contract cancellation is executed. This internally calls EKK0081C160 (Service Contract Cancellation) to cancel the contract header, then iterates over all sub-lines via EKK0161B004 (Service Contract Detail List) and EKK0161C160 (Service Contract Detail Cancellation), skipping already-cancelled or already-rescinded lines (status `"910"` DSLZUMI or `"920"` CANCELZUMI).

5. **Discount Auto-Application (execWrisvcAutoAply)**: Prepares the discount auto-application work data (setting `add_chge_div` to `"05"`, `mskm_sbt_cd` to `"00020"`, `svc_cancel_rsn_cd` to `"10"`, etc.) and calls `JKKWrisvcAutoAplyCC.execute` to apply applicable discounts to the cancelled contract.

6. **Progress Registration (registProgressInfo)**: Registers the progress information with status code `"1201"` (Cancel Complete). This iterates over the movement list (`ido_list`) and maps movement reason codes — defaulting to `"C6"` when no reason code is present.

7. **Conditional Branch — Customer Cancellation**: If the contract was confirmed and the movement type is NOT relocation/registration (`ido_div != "00019"`), the customer common cancellation component is invoked to handle the customer's account de-registration.

8. **Price Code Agreement Consultation (EKK0791A010)**: An inquiry to retrieve the price code agreement details, used to check whether an ID notification letter was issued.

9. **Conditional Branch — Instruction Letter Issuance**: If the contract was confirmed AND the ID notification letter issue identification code is not `"0"` (i.e., it was NOT issued), the instruction letter registration component is called to generate and register the notification letter.

10. **Return**: The original request parameter object is returned with all data populated.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `handle` | `SessionHandle` | Database session handle providing transaction context and database connectivity for SC calls. It carries the connection state, transaction boundaries, and session-level metadata used throughout the cancellation workflow. |
| 2 | `param` | `IRequestParameterReadWrite` | Request parameter container holding the business data map keyed by `fixedText`. Contains fields such as `svc_kei_no` (service detail number), `lastUpdDtm` (last update datetime), `mskm_no` (order number), `func_code` (function code), `ido_div` (movement type), `sysid` (system ID), and `ido_list` (movement detail list). Acts as both input carrier and output accumulator. |
| 3 | `fixedText` | `String` | Used as the data map key to retrieve the central business message (`ccMsg`) from the parameter container. Typically corresponds to a screen-specific message key (e.g., `"KKSV048401CC"` or `"KKSV072916CC"`). Maps to the correct business context across different calling screens. |
