## 1. Role

### JKKSeikyKeiBunkatsuCC.editInMsg_EKU0041C010()

This method constructs the inbound message (input parameter map) for the **"Construction Project — EO Hikari TV Line Various Modifications"** service component invocation (EKU0041C010). It is a message-building / template-assembly method that follows the Builder pattern: it initializes a `CAANMsg` template, populates it with field values extracted from `dataMap` and `childMap` (with null-handling for empty strings), and returns the assembled `paramMap` containing the template in a `CAANMsg[]` array keyed by `JCMConstants.TEMPLATE_LIST_KEY`.

The method serves as the **input-side adapter** for the EO Hikari TV line modification CBS (Custom Business System). It handles multiple business scenarios through conditional branches: (1) billing contract number resolution depends on whether the data exists in `dataMap` versus being newly entered, (2) detail number (`MSKM_DTL_NO`) population differs depending on whether the service contract status is "accepted" (`010`) or not, and (3) for confirmation screens (`FUNC_CODE = "2"`), the billing contract number is overridden from `childMap` to prevent IF-product check failures.

Its role in the larger system is that of a **shared message builder** called by `execEKU0041C010()` (the screen's main processing method) before invoking the SC (Service Component). The same structural pattern is reused across multiple similar methods (e.g., `editInMsg_EKU0061C010` for EO Net Modification), indicating a systematic design approach. The method handles over 200 field assignments, covering customer information, construction project details, address data (both current and pre/post move), scheduling data, and reserved null fields for home equipment (STB/HDD/BS) that are not applicable to TV line modifications.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `IRequestParameterReadWrite` | Business data read/write interface carrying request parameters including control map data (operator ID, operation date/time, function code) and the mapping work area (inter-screen data transfer buffer). |
| 2 | `dataMap` | `Map<String, Object>` | Data map holding persistent screen state between round-trips. Contains `ekk0491d010_seiky_kei_no_work` (billing contract number work field), `KKSV054601SCWORKLIST` (itemized detail list for non-accepted contracts), and `FUNC_CODE` (function code). |
| 3 | `childMap` | `HashMap<String, Object>` | Child data map holding the current screen's field values — extracted from the EO Hikari TV line modification screen (KKSV040326). Contains 50+ fields including service contract number, construction project info, customer info, addresses, timing data, and equipment flags. |

**External state / instance fields read:**
- None directly — all data is passed through parameters. The method calls `editInMsg(param)` which is an inherited method on the base class to populate the common area.

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| U | `JKKSeikyKeiBunkatsuCC.editInMsg` | - | - | Calls `editInMsg(param)` — inherited method to populate the common area (operator info, system date, etc.) in the paramMap. |
| R | `SCW00701SFLogic.getName` | - | - | Referenced in pre-computed evidence; may be used indirectly by the template message system. |
| U | `CAANMsg.set` | - | - | Sets field values on the CAANMsg template — the primary output mechanism of this method. |
| U | `CAANMsg.setNull` | - | - | Clears fields on the template by setting them to null — used for fields not applicable to TV line modifications (home equipment, installation addresses). |

**Note:** This method is a **message builder** — it does not perform any direct database or SC (Service Component) invocations. All work is done through `CAANMsg` template field population. The actual CBS (Custom Business System) call happens in the caller method `execEKU0041C010()` after `editInMsg_EKU0041C010()` returns. The method returns a `paramMap` containing a `CAANMsg[]` array, which the caller then passes to `scCall.run(paramMap, handle)`.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `JKKSeikyKeiBunkatsuCC.execEKU0041C010` | `execEKU0041C010` -> `editInMsg_EKU0041C010` | `editInMsg [U] common_area` |

**Details:** The method is called directly from `execEKU0041C010()` within the same class. The caller is the main processing entry point for the EO Hikari TV line modifications screen. No screen entry point (`KKSV*`) was found within 8 hops in the pre-computed evidence. The terminal operations from this method are all `setNull` calls on the `CAANMsg` template — this method only writes to the template, never to the database.
