## 1. Role

### JKKCancelSvcKeiCC.ctlChshtData()

This method is the **data extraction control processing** (データ抽出制御処理) step within the larger K-Opticom service contract cancellation workflow. Its purpose is to **fetch, assemble, and validate all data records** relevant to a service contract cancellation by invoking a sequence of specialized data-retrieval service methods. It acts as a **centralized orchestration hub** that coordinates the reading of service agreement consent, service detail information, option/sub-option contracts, billing options, contract cancellation details, equipment provision records, optional email opt-in settings (for internet providers), submission details, project association data, and basic project information.

The method handles multiple **service type categories**: eo Hikari Net (SVC_SBT_CD_HNET=1), eo Mobile (SVC_SBT_CD_MOBA=4), eo ADSL (SVC_SBT_CD_ADSL=5), and eo Telephony (SVC_SBT_CD_HTEL=3). For internet-type services (HNET, ADSL, MOBA), it additionally retrieves the customer's email opt-in settings. The method implements a **sequential delegation pattern** — each processing block calls a dedicated getter method and immediately validates the returned status code before proceeding. It follows a **fail-fast design**: if any retrieval step returns a non-normal status, the method aborts and propagates the error code immediately, preventing partial or inconsistent data from being consumed downstream.

Within the larger system, `ctlChshtData` is a **private shared utility** called by `cancelSvcKei` (the main cancellation control entry point, Line 928). It serves as the **Read-heavy preparation phase** that populates `workField` and `trgt_data` with all cancellation-related data, which is then passed to `ctlCancelData` for the actual cancellation execution.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | CBS: `JKKCancelSvcKeiCC.cancelSvcKei` | `cancelSvcKei(handle, param, fixedText)` -> `ctlChshtData(handle, param, trgt_data, workField)` | `callEKK0081A010SC [R] ServiceContractAgreement`, `getSrvKeiUcwkData [R] ServiceContractDetails`, `getOpSbopKeiData [R] OptionContract`, `getSeiOpSvcKeiData [R] BillingOption`, `getSvkeiKaisenUwData [R] ContractCancellation`, `getOptInMailData [R] EmailOptIn`, `getKktkSvcKeiData [R] EquipmentProvision`, `getMskmDtlData [R] SubmissionDetail`, `getSvcKeiKojiakData [R] ServiceContractProject`, `getSvcKeiKihonKojiakData [R] BasicProjectInfo`, `runHiChrgJdgUtil [-] HighChargeJudgment` |

**Caller Context:** `cancelSvcKei` (Line 908) is the main cancellation control method that orchestrates the full service contract cancellation process. It prepares `trgt_data` and `workField`, calls `ctlChshtData` for data extraction, then calls `ctlCancelData` for the actual cancellation execution. Both `ctlChshtData` and `ctlCancelData` are private methods — `cancelSvcKei` is the public entry point.

**Call Chain:** The screen/batch entry point invokes `cancelSvcKei`, which then calls `ctlChshtData`. No additional intermediate CBS layers exist between the screen and `ctlChshtData`.

## 6. Per-Branch Detail Blocks

### Block 1 — [INITIALIZATION] (L1021)

> Initializes status code and service subtype variables. Sets up the default state before data extraction begins.

| # | Type | Code |
|---|------|------|
| 1 | SET | `statusCode = STAT_NORMAL` // [-> `STAT_NORMAL = 0`] Normal termination status [L1022] |
| 2 | SET | `svcSbtCd = SVC_SBT_CD_DFLT` // [-> `SVC_SBT_CD_DFLT = 0`] Default service subtype code [L1024] |
| 3 | SET | `svcCd = null` // Service code — will be extracted from agreement result [L1026] |
| 4 | SET | `prcGrpCd = null` // Processing group code — will be extracted [L1027] |
| 5 | SET | `eKK0081A010Hash = new HashMap<String, Object>()` // Local hash for service contract agreement result [L1042] |

### Block 2 — [CALL] Service Contract Agreement Inquiry (L1043)

> Invokes CBS `EKK0081A010SC` to retrieve service contract agreement consent details (K-Opticom cancellation consent). The CBS returns data including service contract number (`svc_kei_no`), service code (`svc_cd`), service status (`svc_kei_stat`), submission detail number (`mskm_dtl_no`), etc. per `EKK0081A010CBSMsg1List` schema.

### Block 3 — [IF] Null Check on Agreement Result (L1046)

> Checks if the CBS returned no data. This case should not normally occur — it represents a scenario where data existed during screen display/batch extraction but was deleted before K-Opticom internal processing.

| # | Type | Code |
|---|------|------|
| 1 | IF | `isNull(eKK0081A010Hash)` [L1046] |

### Block 5 — [EXTRACTION] Derive Service Type (L1056–1058)

> Extracts the service code and processing group code from the agreement result hash, then determines the specific service subtype (HNET, HTel, MOBA, ADSL).

| # | Type | Code |
|---|------|------|
| 1 | SET | `svcCd = (String)eKK0081A010Hash.get(EKK0081A010CBSMsg1List.SVC_CD)` // [-> `svc_cd` field] Extract service code [L1056] |
| 2 | SET | `prcGrpCd = (String)eKK0081A010Hash.get(EKK0081A010CBSMsg1List.PRC_GRP_CD)` // [-> `prc_grp_cd` field] Extract processing group code [L1057] |
| 3 | CALL | `svcSbtCd = getSvcSbtCd(svcCd, prcGrpCd)` // Determine service subtype: HNET=1, HTel=3, MOBA=4, ADSL=5 [L1058] |

### Block 6 — [CALL] High-Charge Judgment Utility (L1062–1070)

> Calls the DSL service high-charge judgment utility. This is an OM-2013-0001096 update (Non-charge actual execution department product execution) that determines whether high charges apply to the DSL service.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `cancelSvcKeiMapper.runHiChrgJdgUtil(handle, param, trgt_data, workField, eKK0081A010Hash, null, null, null, DSL_SBT_FLG_SVC_KEI_DSL)` // DSL high-charge judgment [L1062–1070] |
| 1.1 | PARAM | `DSL_SBT_FLG_SVC_KEI_DSL` // [-> `"1"`] DSL service type flag [L1070] |

### Block 7 — [IF] Service Contract Details Retrieval (L1076–1080)

| # | Type | Code |
|---|------|------|
| 1 | CALL | `statusCode = getSrvKeiUcwkData(param, handle, svcSbtCd, trgt_data, workField)` // Retrieve service contract details [L1076] |
| 2 | IF | `statusCode != STAT_NORMAL` [L1078] |
| 2.1 | RETURN | `return statusCode` // Fail fast on error [L1080] |

### Block 8 — [IF] Option Contract and Sub-option Info Retrieval (L1086–1090)
