## 1. Role

### JFUCngSeikyushoYohiCC.setInMapEKK0491C060()

This method is an **upward mapping item setter** (上りマッピング項目設定) that populates an input map (`inMap`) with all data fields required for the **Invoice Delivery Destination Change** (請求書送付先変更) business operation. In the K-Opticom telecommunications billing system, when a customer requests a change to the address or contact details on which their invoices are mailed, this method assembles every required and optional field into the processing map before it is handed off to downstream service components.

The method implements a **direct mapping / data assembly pattern** — it does not perform conditional routing or branching logic. Instead, it sequentially maps 34 fields from two source maps (`ccMap` for contract-level data and `inMap` for previously prepared values) into the output `inMap`. Some fields are system-generated (e.g., the operation date via `JCCBPCommon.getOpeDate`, or the fixed change type code `"00015"`), while most are passed through verbatim from upstream sources.

Within the larger system, this method serves as a **shared mapping utility** called from `cngSeikyushoYohi()`, which is the screen-level entry point for the Invoice Delivery Destination Change screen (KKSV0004). It is a critical data transformation step that bridges the request parameter layer with the CBS (Component-Based Service) layer, ensuring all required fields are present and properly typed before persistence.

**Processing Summary:**

The method follows a **linear, unconditional** flow — no `if/else` or `switch` branches exist. All 34 field assignments execute in sequence:

1. **Error suppression initialization** — `JFUBaseUtil.ignoreSearchError` clears search errors on the request parameter.
2. **Map extraction** — `param.getData(fixedText)` retrieves the input map from the request parameter.
3. **Required fields** (5 fields) — These are mandatory business keys and system values:
   - `SEIKY_KEI_NO` — Invoice contract number, sourced from `ccMap`
   - `MSKM_DTL_NO` — Application detail number, sourced from `ccMap`
   - `RSV_APLY_YMD` — Reservation application date, sourced from `JCCBPCommon.getOpeDate()`
   - `IDO_DIV` — Change type code, set to the fixed constant `"00015"` from `JFUStrConst.CD00576_00015`
   - `UPD_DTM_BF` — Update datetime before change, sourced from existing `inMap`
4. **Optional fields** (29 fields) — All sourced from either `ccMap` (1 field: `SEIKYUS_HAKKO_YH`) or `inMap` (28 fields), covering delivery destination address, contact info, flags, and first billing details.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `param` | `IRequestParameterReadWrite` | The request parameter object that carries all input data from the screen. Its `getData(fixedText)` method retrieves the named map (`inMap`) where mapping items will be populated. This is the primary data exchange mechanism between the screen layer and business components. |
| 2 | `fixedText` | `String` | A service message key used to identify and retrieve the correct data map from `param`. It acts as a namespace or session key within the request parameter object. |
| 3 | `ccMap` | `HashMap<String, Object>` | The "contract change map" — a shared context map that carries contract-level data across the processing chain. It provides values for required fields (`SEIKY_KEI_NO`, `MAP_KEY_MSKM_DTL_NO`, `SEIKYUS_HAKKO_YH_NEW`) that originate from the contract change screen. |

**External state / instance fields read:**

| Field | Source Class | Business Description |
|-------|--------------|---------------------|
| `SEIKY_KEI_NO` | `FUSV0063_FUSV0063OP_FUSV006301CC` (static import) | Contract number key — the mapping key used to retrieve the invoice contract number from `ccMap` |
| `MAP_KEY_MSKM_DTL_NO` | Instance/inner constant of `JFUCngSeikyushoYohiCC` | Application detail number key — the mapping key for retrieving the submission detail number from `ccMap` |
| `MAP_KEY_UPD_DTM` | Instance/inner constant of `JFUCngSeikyushoYohiCC` | Update datetime key — used to read the pre-update timestamp from the existing `inMap` |
| `SEIKYUS_HAKKO_YH_NEW` | `FUSV0063_FUSV0063OP_FUSV006301CC` (static import) | Invoice issuance necessity new — the mapping key for retrieving whether an invoice should be issued from `ccMap` |
| `EKK0491C060CBSMsg.*` | `eo.ejb.cbs.cbsmsg.EKK0491C060CBSMsg` (static field references) | CBS message constants defining the field name keys used as map keys in `inMap.put()` calls |
| `JCCBPCommon` | `eo.ejb.cbs.cbs.JCCBPCommon` (utility class) | Business common component providing `getOpeDate()` for system date retrieval |
| `JFUStrConst.CD00576_00015` | `eo.common.constant.JFUStrConst` (constant) | Fixed constant value `"00015"` — represents the change type (異動区分) code |
| `EKK0491A010CBSMsg1List.FIRST_SEIKY_YM` | `eo.ejb.cbs.cbsmsg.EKK0491A010CBSMsg1List` | First billing month key — referenced from a related CBS message list class |
| `JFUBaseUtil` | `eo.common.util.JFUBaseUtil` (utility class) | Base utility providing `ignoreSearchError()` for error suppression |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `JCCBPCommon.getOpeDate` | (utility) | - | Retrieves the current operation date for the `RSV_APLY_YMD` (Reservation Application Date) field. This is a read-only system date accessor. |

**Notes on other pre-computed evidence:** The pre-computed graph lists many downstream calls (`getData`, `ignoreSearchError`, `getOpeDate` from various SC classes), but these are **not directly invoked** within `setInMapEKK0491C060`. They appear at the deeper call-chain level (e.g., in callers like `cngSeikyushoYohi()` or in CBS methods that consume the populated `inMap`). This method itself only makes two direct external calls: `JFUBaseUtil.ignoreSearchError()` and `JCCBPCommon.getOpeDate()`.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV0004 (Invoice Delivery Destination Change) | `cngSeikyushoYohi()` -> `setInMapEKK0491C060(param, fixedText, ccMap)` | (see Section 4 — no terminal SC calls from this method; it passes data to callers) |

**Pre-computed caller analysis:**

| # | Caller (Screen/Batch) | Call Chain | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | JFUCngSeikyushoYohiCC.cngSeikyushoYohi() | `cngSeikyushoYohi()` -> `setInMapEKK0491C060(param, fixedText, ccMap)` | — |

The method is a private utility called exclusively from `cngSeikyushoYohi()`, which is the business logic method for the Invoice Delivery Destination Change screen. The terminal operations reachable from this method are read-only system lookups (`getOpeDate`) and error suppression (`ignoreSearchError`), with no direct data mutation or SC invocation at this level.

## 6. Per-Branch Detail Blocks

This method contains **no conditional branching** (no `if`, `else`, `switch`, or `for` loops). The entire method is a single linear block.

**Block 1** — [SET / EXEC] `(linear field mapping)` (L1238)

> Suppress search errors, retrieve the inMap, then populate all required and optional fields. No conditional logic — every line executes unconditionally in sequence.
