## 1. Role

### JKKKisnUwHmdkAddCC.editInMsgEKK0251C030()

This method is a dedicated message builder for the Service Contract Withdrawal Internal Content Change (EKK0251C030) CBS (CBS = Core Business System) interface. It constructs the input message payload (`Object[][]`) required to invoke the withdrawal internal content change service. The method operates in a business merger/migration context: two service contracts — a pre-merger contract (合併元 `mtEkk0251Msg`) and a post-merger contract (合併先 `skEkk0251Msg`) — have already been fetched separately, and this method merges their data into a single outgoing request. It uses a merge-fallback strategy: for each business field, it prefers the post-merger value if present, and falls back to the pre-merger value when the post-merger side has no data. This ensures that merger-related field updates are preserved while defaulting to the original contract's values where no merger-side data exists. The method also hardcodes structural metadata fields such as template ID (`EKK0251C030`) and function code (`"1"` for update mode). It implements a builder pattern with a delegation-based value resolution strategy, and its output is consumed directly by `callSC` to invoke the CBS.

**CRITICAL — Constant Resolution:**

| Constant | Resolved Value | Business Meaning |
|----------|---------------|------------------|
| `TEMPLATE_ID_EKK0251C030` | `"EKK0251C030"` | Service interface template ID for withdrawal internal content change |
| `FUNC_CODE = "1"` | `"1"` | Update mode (function code distinguishing read vs. write operations) |
| `ROZETT_STC_STAT_CD_ST_ZM` | `"1"` | Socket installation status = "Installed" — used in getUpdValueRzt conditional logic |
| `EKK0251A010CBSMsg1List.LAST_UPD_DTM` | `LAST_UPD_DTM` | Last update datetime — used as pre-update timestamp for optimistic concurrency control |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `ccMsg` | `HashMap<String, Object>` | Context map carrying merger metadata, specifically the post-merger service contract withdrawal work number (`heigo_sk_svc_kei_kaisen_ucwk_no`). This map is populated by the caller and provides the business key linking the merged contract to the withdrawal change request. |
| 2 | `mtEkk0251Msg` | `CAANMsg` | Pre-merger (merged-to) service contract withdrawal agreement data. Contains original contract fields that serve as fallback values. Corresponds to the original contract before merger consolidation. |
| 3 | `skEkk0251Msg` | `CAANMsg` | Post-merger (merged-from) service contract withdrawal agreement data. Contains the current/updated contract fields that are preferred during the merge. Represents the target contract after merger consolidation. |
| 4 | `mtMskmDtlNo` | `String` | Application detail number (申込明细番 — the detail line number identifying a specific application line item within the service contract). Used as a key to associate the withdrawal change request with the correct application record. |

**Internal helper methods used:**

| Name | Description |
|------|-------------|
| `getUpdValue(key, skMsg, mtMsg)` | Standard merge-fallback: returns `skMsg` value if non-null, otherwise returns `mtMsg` value. Used for ~44 standard fields (address, telephone, coordinates, scheduling, etc.). |
| `getUpdValueRzt(key, skMsg, mtMsg)` | Special merge-fallback for ANK-4038 fields (socket/concentrator/end device status codes). Only uses `mtMsg` value when `sk` ROZETT status != "1" AND `mt` ROZETT status = "1" (socket installed in pre-merger but not post-merger). Otherwise falls back to `sk` value. |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `skEkk0251Msg.getString` | EKK0251A010CBSMsg1List | - | Reads LAST_UPD_DTM (last update datetime) from the post-merger CAANMsg for optimistic concurrency |
| R | `getUpdValue` | JKKKisnUwHmdkAddCC | - | Reads values from skEkk0251Msg (post-merger) with fallback to mtEkk0251Msg (pre-merger) for standard fields |
| R | `getUpdValueRzt` | JKKKisnUwHmdkAddCC | - | Reads ANK-4038 fields with socket status conditional logic — checks ROZETT_STC_STAT_CD from both messages |

### Called CBS:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `callSC(handle, scCall, param, fixedText, ekk0251c030In)` (invoked by caller `execUpdSvcKeiKaisenUcwk`) | EKK0251C030SC | KK_T_SVC_KEI_KAISEN_UCWK, KK_T_SVC_KEI_KAISEN_UCWK_DTL (inferred from CBSMsg schema) | Service Contract Withdrawal Internal Content Change — called by the parent method `execUpdSvcKeiKaisenUcwk` with the built `inList` payload to execute the CBS update operation |

**Note:** This method itself is a pure message builder — it performs no direct database operations. All reads are from in-memory `CAANMsg` objects. The CBS invocation is handled by the caller `execUpdSvcKeiKaisenUcwk`, which calls `callSC` with the returned `Object[][]` payload.

## 5. Dependency Trace

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

No screen/batch entry points found within 8 hops. Direct callers found: 2 methods.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | CBS: `JKKKisnUwHmdkAddCC.execUpdSvcKeiKaisenUcwk` | `execUpdSvcKeiKaisenUcwk` -> `editInMsgEKK0251C030(ccMsg, mtEkk0251a010Out[0], skEkk0251a010Out[0], mskmDtlNo)` -> `callSC(EKK0251C030)` | `callSC [C/U] EKK0251C030CBS (Service Contract Withdrawal Internal Content Change)` |
| 2 | CBS: `JKKSvkeiShosaCC.editUpdPlaceNo` | `editUpdPlaceNo(place_no, ...)` -> `shosaOkMapper.editInMsgEKK0251C030(param, childTemplate, place_no, workEKK0251A010)` -> `editInMsgCmn` | `editInMsgCmn [R] EKK0251C030CBSMSG1LIST` |

**Caller 1 — `execUpdSvcKeiKaisenUcwk`:** This private method fetches both pre-merger and post-merger service contract withdrawal agreement data via `EKK0251A010CBS`, then builds the withdrawal internal content change input message via `editInMsgEKK0251C030`, and finally executes the `EKK0251C030` CBS via `callSC`.

**Caller 2 — `JKKSvkeiShosaCC.editUpdPlaceNo`:** This CBS handler is invoked during place number update processing in screen EKK0251. It iterates over place records and calls `editInMsgEKK0251C030` (via `shosaOkMapper` mapping) for each unique place number to build update payloads, which are then processed by `editInMsgCmn`.

## 6. Per-Branch Detail Blocks

### Block 1 — INIT (L1508)

Initialize the `Object[][] inList` array to hold field key-value pairs for the CBS input message.

| # | Type | Code |
|---|------|------|
| 1 | SET | `Object[][] inList = {...}` // Initialize 2D array for CBS input message |

### Block 2 — Fixed/ Mandatory Fields (L1509–L1513)

Set structural metadata fields that are always the same regardless of merger state.

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | SET | `{TEMPLATEID, "EKK0251C030"}` // [-> TEMPLATE_ID_EKK0251C030 = "EKK0251C030"] | Template ID for CBS interface identification |
| 2 | SET | `{FUNC_CODE, "1"}` | Function code = "1" indicating update/modify mode |
| 3 | SET | `{SVC_KEI_KAISEN_UCWK_NO, ccMsg.get("heigo_sk_svc_kei_kaisen_ucwk_no")}` | Post-merger service contract withdrawal work number from context map |
| 4 | SET | `{MSKM_DTL_NO, mtMskmDtlNo}` | Application detail number passed as method parameter |
| 5 | SET | `{UPD_DTM_BF, skEkk0251Msg.getString(LAST_UPD_DTM)}` | Last update datetime from post-merger msg — used for optimistic concurrency control in CBS |

### Block 3 — Standard Fields Merge via getUpdValue (L1514–L1572)

> // 以下の項目は合併先に値がない場合のみ合併元の値を設定
> // The following fields: set the pre-merger value only if the post-merger side has no value

For each of ~44 standard fields, call `getUpdValue(key, skEkk0251Msg, mtEkk0251Msg)` which implements: if `sk` (post-merger) value is non-null, use it; otherwise fall back to `mt` (pre-merger) value.

### Block 4 — ANK-4038 Modified Fields: getUpdValue (L1574–L1575)

> // ANK-4038-00-00 MOD START

Two additional fields added under ANK-4038 modification ticket, still using standard `getUpdValue`:

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | SET | `KISN_AD_CHK_LV` | Line location address check level |
| 2 | SET | (no action — comment line `ANK-4038-00-00 MOD START`) | Modification marker comment |

### Block 5 — ANK-4038 Special Fields: getUpdValueRzt (L1576–L1590)

> // ANK-4038-00-00 MOD END

Ten fields with special merge logic via `getUpdValueRzt`. These handle socket/concentrator/end device installation status codes that require conditional resolution based on `ROZETT_STC_STAT_CD`.

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | SET | `{ROZETT_STC_STAT_CD, getUpdValueRzt(..., ROZETT_STC_STAT_CD, ...)}` | Socket installation status code |
| 2 | SET | `{CONSNT_STC_NYO_CD, getUpdValueRzt(..., CONSNT_STC_NYO_CD, ...)}` | Concentrator installation content code |
| 3 | SET | `{TNMT_STC_FLR_CD, getUpdValueRzt(..., TNMT_STC_FLR_CD, ...)}` | Terminal installation floor code |
| 4 | SET | `{KISN_TD_SETPLC_1_CD, getUpdValueRzt(..., KISN_TD_SETPLC_1_CD, ...)}` | Line terminal installation location code 1 |

| 8 | SET | `{KISN_TD_SETPLC_2_OTR, getUpdValueRzt(..., KISN_TD_SETPLC_2_OTR, ...)}` | Line terminal installation location 2 other |
| 9 | SET | `{KISN_TD_STC_KASHO_OTR, getUpdValueRzt(..., KISN_TD_STC_KASHO_OTR, ...)}` | Line terminal installation place other |
| 10 | SET | `{TANMT_STC_MEN_CD, getUpdValueRzt(..., TANMT_STC_MEN_CD, ...)}` | Terminal installation face code |

#### Block 5.1 — getUpdValueRzt Conditional Logic (L1619–L1628)

For each ANK-4038 field, the `getUpdValueRzt` method evaluates:

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | IF | `!ROZETT_STC_STAT_CD_ST_ZM.equals(skEkk0251Msg.getString(ROZETT_STC_STAT_CD)) && ROZETT_STC_STAT_CD_ST_ZM.equals(mtEkk0251Msg.getString(ROZETT_STC_STAT_CD))` | [-> ROZETT_STC_STAT_CD_ST_ZM = "1"] Check: post-merger socket status != "1" AND pre-merger socket status = "1" |
| 2 | THEN (true) | `return mtEkk0251Msg.getString(content);` // 合併元の値を設定 — Set the pre-merger value | Pre-merger has socket installed but post-merger does not — carry forward the pre-merger value |
| 3 | ELSE (false) | `return skEkk0251Msg.getString(content);` | Use post-merger value (socket status consistent between both sides) |

### Block 6 — RETURN (L1593–L1595)

| # | Type | Code |
|---|------|------|
| 1 | RETURN | `return inList;` // Return the fully assembled CBS input message |
