## 1. Role

### JKKSeikySakiHeigoCC.editInMsg_EKK0011D020()

This method creates the input message template for the **Order Content Approval Registration** service (service code: EKK0011D020). In the K-Opticom customer core system, telecom orders for new installations (such as FTTH broadband connections) must pass through an approval workflow before activation. This method constructs the `CAANMsg` request payload that will be dispatched to the backend service component `EKK0011D020CBS` via the `scCall.run()` invocation.

The method implements the **Builder pattern** for CBS message construction: it instantiates a typed `CAANMsg` template keyed by `EKK0011D020CBSMsg`, populates common metadata fields (operator ID, operating date, operating datetime), maps 17 business-level fields from the `childMap` (which carries the form-submitted order content approval registration data submitted by the customer), and conditionally creates a nested detail message array for order detail items. It delegates common-area field extraction to `editInMsg(param)` which sets up shared control data.

The method serves as the **message-building stage** within the larger `execEKK0011D020()` flow, which chains this call with the actual SC invocation and result processing. It is a shared utility called by multiple screens — `JKKSeikySakiHeigoCC.execEKK0011D020()`, `JKKSeikyKeiHenkoCC`, `JKKEohTvCourseChgClCC`, `JKKEohTvCourseChgCC`, and `JKKCreateNhkDntIktCC` — all of which need to register order content approval as part of their service contract change or new subscription flows.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `IRequestParameterReadWrite` | The request parameter object that carries both **control data** (operator ID, operating date/time from the session control map) and **user data** (the `KKSV0546CCList` hash map containing order-related screen data). It is also mutated in-place by `editInMsg(param)` for common area setup, and by `param.put(TEMPLATE_LIST_KEY, templates)` to attach the assembled template for downstream SC dispatch. |
| 2 | `dataMap` | `Map<String, Object>` | A map containing execution context metadata. Specifically, it provides the **function code** (`JCMConstants.FUNC_CODE_KEY`) which overrides the default `"1"` value set during template initialization. The function code identifies the calling business scenario (e.g., new subscription, contract change). |
| 3 | `childMap` | `HashMap<String, Object>` | Carries the **Order Content Approval Registration data** submitted from the UI — this is the child/order detail data for the approval registration. Contains fields such as `sysid`, `mskm_sbt_cd` (application type code), `mskmsho_ariv_ymd` (application receipt date), `kari_mskm_flg` (provisional application flag), `cust_yobo_jiko` (customer request items), and 14 other customer-facing order fields. |

**External state / instance fields read:**

| Field | Type | Business Description |
|-------|------|---------------------|
| (none directly) | — | This method is stateless; all state is passed via parameters. It delegates to `editInMsg(param)` which may read instance-level template configuration. |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| U | `editInMsg` | JKKSeikySakiHeigoCC | - | Calls `editInMsg(param)` to populate common area fields (operator ID, operating date, etc.) from control map data |
| R | `param.getData` | - | - | Reads user data from `KKSV0546CCList` — the screen's user data hash map |

**Additional calls within this method (message builder operations, no database interaction):**

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| U | `CAANMsg.set` / `CAANMsg.setNull` | - | - | Populates the `EKK0011D020CBSMsg` template with 17 mapped fields + common metadata (template ID, function code, operator info). These are in-memory field assignments. |
| U | `CAANMsg[]` creation | - | - | Creates the nested `EKK0011D020CBSMsg1List` detail message array with 39 null-initialized fields when `inList` is null. |
| U | `paramMap.put` | - | - | Inserts the assembled `CAANMsg[]` templates into the return parameter map keyed by `JCMConstants.TEMPLATE_LIST_KEY`. |

**Analysis:** This method performs **zero database operations**. It is purely a **message construction/builder** method. All operations are in-memory `set()` and `setNull()` calls on `CAANMsg` objects. The actual CRUD happens in the called CBS `EKK0011D020CBS` (invoked by `scCall.run()` in the caller `execEKK0011D020`).

## 5. Dependency Trace

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

No screen/batch entry points found within 8 hops. Direct callers found: 1 method within this class.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `JKKSeikySakiHeigoCC.execEKK0011D020()` | `execEKK0011D020()` -> `editInMsg_EKK0011D020()` | `editInMsg[paramMap.put]`, `setNull` [-] x15, `CAANMsg.set` [-] x17, `CAANMsg[]` creation [-] |

**Additional callers found across the codebase (same method name in different classes):**

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 2 | `JKKSeikyKeiHenkoCC` | `JKKSeikyKeiHenkoCC` (own copy of `editInMsg_EKK0011D020`) | — (same class, different file) |
| 3 | `JKKEohTvCourseChgClCC` | `JKKEohTvCourseChgClCC` (own copy) | — (same class, different file) |
| 4 | `JKKEohTvCourseChgCC` | `JKKEohTvCourseChgCC` (own copy) | — (same class, different file) |
| 5 | `JKKCreateNhkDntIktCC` | `JKKCreateNhkDntIktCC` (own copy) | — (same class, different file) |

**Note:** The method `editInMsg_EKK0011D020` is **re-implemented** in multiple CC classes (`JKKSeikyKeiHenkoCC`, `JKKEohTvCourseChgClCC`, `JKKEohTvCourseChgCC`, `JKKCreateNhkDntIktCC`) with nearly identical logic. The version documented here is the canonical implementation in `JKKSeikySakiHeigoCC` which serves as the primary entry point via `execEKK0011D020()`. The actual CBS call (`EKK0011D020CBS`) reaches terminal operations in the CBS layer.
