## 1. Role

### JKKCancelSvcWribCC.editRetEKK0451C070()

This method performs the **downstream mapping processing for discounted service contract cancellation** (割引サービス契約キャンセルの下りマッピング処理). It is a private utility method that transforms outbound message data received from a Service Component call into a standardized parameter map for consumption by the presentation layer or subsequent processing stages. Specifically, it reads a `CAANMsg` template array from the incoming `msgList` (which carries structured CBS response data for discount service contract cancellation) and maps each relevant field into a `dataMap` and a nested `workDataMap`. The method processes 11 response fields — all via a consistent conditional null-safety pattern: if the template field is null, an empty string is stored; otherwise, the string value is extracted and placed into both the result data map and the work area. This dual-write strategy preserves the data in both the method return payload and the broader work context. The method delegates error handling to `editErrInfoEKK0451C070()` and consolidates error information via `TemplateErrorUtil.getErrorInfo()`. It functions as a shared transformation utility invoked from `cancelSvcWrib()` during the cancellation main processing flow, handling both discount (割引) and miscellaneous (汎用) service types.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `msgList` | `Map<?, ?>` | The outbound message list from the CBS Service Component call. Contains the `CAANMsg[]` template array at key `JCMConstants.TEMPLATE_LIST_KEY` (holding the structured cancellation response data), and a return code at `JCMConstants.RET_CD_INT_KEY` for error handling. This carries the raw service contract cancellation results from the backend CBS layer. |
| 2 | `param` | `IRequestParameterReadWrite` | The request parameter object that serves as the primary data carrier. It holds work area mappings (`getMappingWorkArea`/`setMappingWorkArea`), the result data map (`getData`/`setData` keyed by `fixedText`), and control map data for error info (`getControlMapData`/`setControlMapData`). Modified in-place to accumulate all mapped fields. |
| 3 | `fixedText` | `String` | A string key used to scope the data map within `param`. Acts as a namespace/discriminator to allow multiple data payloads to coexist within the same parameter object. In the caller context, it identifies the specific processing block (the `ccName` passed through from `cancelSvcWrib`). |

**Instance fields read:**

| Field | Type | Business Meaning |
|-------|------|------------------|
| `wribSvcKei` | `HashMap<String, String>` | Service contract number to last update date/time mapping for discount services (サービス契約番号に対する最終更新日時分秒（割引サービス）). Iterated over during `UPD_DTM` processing to set the last update date for each service contract number. |

**Instructions:**

The only direct caller of `editRetEKK0451C070()` is the sibling method `cancelSvcWrib()` within `JKKCancelSvcWribCC`. `cancelSvcWrib()` is the main cancellation processing entry point for discount service contracts. It invokes a Service Component via `ServiceComponentRequestInvoker`, receives the response in `msgList`, and calls `editRetEKK0451C070()` to map the CBS response fields to the parameter structure. The method iterates over service contract lists (`wribSvcCdList`, `hanyoCdList`) and dispatches the downstream mapping for each entry.

Terminal operations from this method: `setData` [-], `getErrorInfo` [R], `getErrorInfo` [R], `getErrorInfo` [R], `editErrInfoEKK0451C070` [U], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `getString` [R], `isNull` [-], `isNull` [-], `isNull` [-], `isNull` [-], `isNull` [-]
