## 1. Role

### JKKAdchgCancelHakkoSODCC.editResultRP_EKK0341B002CBS()

This method is a **result mapping and error-handling component** for the "Device-Provisioned Service Contract List Inquiry (by Service Contract Number)" screen — specifically handling the **downward (result-side) mapping** after a Service Component (SC/CBS) call has been executed. In Japanese, the Javadoc states: "下りマッピング（機器提供サービス契約一覧照会（サービス契約番号））" (Downward mapping — Device-Provisioned Service Contract List Inquiry (by Service Contract Number)), and "サービスコンポーネント実行後に、IRequestParameterReadWriteに必要なデータをマッピングします" (After executing the service component, map the required data into IRequestParameterReadWrite).

The method performs three core business responsibilities in sequence:

1. **Template extraction and list mapping**: Extracts `CAANMsg` template arrays from the SC return map, iterates over each service contract record, and maps 12 response fields (generation timestamp, service keys, codes, status, pricing) into a structured `ArrayList<HashMap>` working data structure.
2. **Error information retrieval**: Delegates to `editErrorInfo_EKK0341B002CBS` to extract error details from the SC response templates and return code, then applies error mapping via `TemplateErrorUtil.getErrorInfo`.
3. **Error-driven exception gating**: If any errors were detected (non-empty `errList`), throws a `CCException` wrapping an `SCCallException` containing the return code and SC status — implementing a fail-fast error-propagation pattern that prevents partially-processed results from reaching the UI layer.

The method acts as a **shared template result mapper** called by multiple screen CC methods (e.g., `getKktkSvcKeiList` in both `JKKAdchgHakkoSODCC` and `JKKHakkoSODCC`), following a standard pattern where screen-level business logic components delegate the SC result interpretation to a centralized, method-name-specific mapping routine. No conditional branches exist on service types or order content codes — the method processes all records uniformly.

**Branch summary:**
- **dataMap null -> Yes**: Initialize a new HashMap and store it back into `param` under key `HAKKOSODCCWORK`. (L15364-L15367)
- **dataList null -> Yes**: Initialize a new ArrayList for the result list. (L15377-L15379)
- **templateArray null -> Yes**: Skip the field-mapping loop entirely; result list stays empty or pre-existing. (L15381-L15509)
- **i >= dataList.size() -> Yes**: Append a new empty HashMap to `dataList` before reading. (L15389-L15391)
- **Field null checks**: For each of the 12 fields, if `childTemplate.isNull(fieldKey)` is true, put an empty string `""`; otherwise put `childTemplate.getString(fieldKey)`. (L15399-L15508)
- **errList not null AND not empty -> Yes**: Throw `CCException` wrapping `SCCallException` with return code and status. (L15522-L15523)

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `msgList` | `Map<?, ?>` | The raw return map from a Service Component / CBS call (EKK0341B002CBS). Contains the `CAANMsg` template array (keyed by `TEMPLATE_LIST_KEY`) for message structure parsing, and the integer return code (keyed by `RET_CD_INT_KEY`). This carries the SC's response payload including any error information. |
| 2 | `param` | `IRequestParameterReadWrite` | The business data request/response parameter object that holds working maps, control maps, and screen data. Used both as input (to read the working map) and output (to write mapped results and error info back). |

**Instance/external state read:**
| Source | Description |
|--------|-------------|
| `JKKHakkoSODConstCC.HAKKOSODCCWORKMAP` | Constant `"HakkoSODCCWORK"` — the working map key used to store and retrieve intermediate service contract list data across methods. |
| `JCMConstants.TEMPLATE_LIST_KEY` | Constant for the key used to retrieve the `CAANMsg[]` template array from the SC return map. |
| `JCMConstants.RET_CD_INT_KEY` | Constant for the key used to retrieve the integer return code from the SC return map. |
| `EKK0341B002CBSMsg.EKK0341B002CBSMSG1LIST` | Constant key for the message list element within the CBS response structure. |
| `SCControlMapKeys.ERROR_INFO` | Constant key for the error information control map entry. |

**Detailed method-by-method analysis:**

This method performs **no direct database CRUD operations** itself. Instead, it is a **post-call result mapper** that processes data returned from the SC/CBS call `EKK0341B002CBS` (which was invoked by the caller -- see Section 5 -- and presumably queries the device-provisioned service contract tables).

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `parentTemplate.getMsgData` | EKK0341B002CBS | (inferred: device-provisioned service contract list tables) | Reads the CAANMsg result list from the CBS return, which was populated by querying device-provisioned service contract data |
| R | `childTemplate.getString` | EKK0341B002CBSMsg1List | (inferred: service contract detail records) | Reads 12 fields per record from the CBS response -- generation timestamp, service key numbers, service codes, device manufacturing numbers, pricing/group codes |
| U | `editErrorInfo_EKK0341B002CBS` | JKKAdchgCancelHakkoSODCC | - | Processes error info from SC/CBS response templates and return code |
| U | `TemplateErrorUtil.getErrorInfo` | TemplateErrorUtil | - | Aggregates error information from templates into error list |

**Key findings on callers:**
- In `JKKAdchgHakkoSODCC` (line 16088): Called from `getKktkSvcKeiList()` after an `EKK0341B002SC` service call via `ServiceComponentRequestInvoker`.
- In `JKKHakkoSODCC` (line 23013): Called identically from `getKktkSvcKeiList()` after the same SC invocation.
- In the current class `JKKAdchgCancelHakkoSODCC` (line 13631): The call site is **commented out** (`//`), suggesting this method may be a copy-port or deprecated. The method is defined but not actively invoked in this class.
