## 1. Role

### JBSbatKKAdChgAddDataCst.setNewKaisenTgSvkei()

This method populates the output map (`outMap`) with the **transferred-to service contract** fields for a residential address change (住所変更) batch process. In the Japanese telecom domain, when a customer moves to a new address, their existing service contracts (line items) must be ported — or "transferred" (移転 — *iten*) — from the old location to the new one. This method sets the "itens" (転先) side of the transfer: the destination address's contract data.

The method implements a **service-type routing/dispatch pattern**: it inspects the `svcCd` (service code) parameter and branches into one of three service-category branches — **Net** (インターネット / Internet, code "01"), **Tel** (電話 / Telephone, code "02"), or **TV** (テレビ / Broadcast TV, code "03") — setting service-type-specific output map keys for each branch. A default "else" branch silently ignores any unrecognized service code.

For every data field set by the method, a null-or-blank guard is applied: if the source value is blank, an empty string `""` is written to the output map (effectively a safe no-op), preserving the map's structure while ensuring no nulls leak downstream. This is a shared utility called by `execute()` within the same class, serving as a data assembler in the batch processing pipeline for address-change service contract updates (住所変更更新工事事実完了抽出 — residential address change update work fact completion extraction).

The method operates purely as a data setter — it has no side effects beyond writing to the output map, and does not touch the database directly.

**CRITICAL — Constant Resolution:**

| Constant | Resolved Value | Business Meaning |
|----------|---------------|------------------|
| `JKKBatConst.SVC_CD_NET` | `"01"` | Internet service code (FTTH broadband) |
| `JKKBatConst.SVC_CD_TEL` | `"02"` | Telephone service code |
| `JKKBatConst.SVC_CD_TV` | `"03"` | Broadcast TV (CS/BS) service code |

The method branches on `svcCd` against these constants. Each matched branch sets three output-map keys specific to that service type: the service contract number, the line detail usage start date, and the transfer-to line-target service contract update datetime.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `outMap` | `JBSbatServiceInterfaceMap` | The output map into which the method sets transferred-to service contract fields. This map is the interface contract carrying data from the batch processing stage to downstream consumers (file output or further processing). |
| 2 | `svcCd` | `String` | Service code that determines which service category the data belongs to. Valid values: `"01"` (Net/Internet), `"02"` (Tel/Telephone), `"03"` (TV/Broadcast). Any other value causes all service-type-specific fields to be skipped (silently ignored). |
| 3 | `itnsSvcKeiKaisenUcwkNo` | `String` | Transferred-to service contract line detail number (移転先サービス契約回線内訳番号). This is the internal tracking identifier for the specific line item being transferred to the destination address. |
| 4 | `ItnsSvcKeiNo` | `String` | Transferred-to service contract number (移転先サービス契約番号). The main contract identifier for the destination-side service. Set differently per service type (NET/Tel/TV keys). |
| 5 | `kaisenUcwkUseStaymd` | `String` | Line detail usage start date (回線内訳使用開始年月日). A date string (e.g., "20240101") indicating when the transferred line item becomes active at the new address. |
| 6 | `itnsKisnTgSvkeiUpdDtm` | `String` | Transferred-to line-target service contract update datetime (移転先回線対象サービス契約更新年月日時分秒). A timestamp string recording when the destination contract was last modified, used for audit and version tracking. |

**No instance fields or external state** are read by this method. It operates purely on its parameters and the `outMap` parameter.

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `outMap.getString(JBSbatKKIFM101.ITNS_SVC_KEI_KAISEN_UCWK_NO)` | - | - | Reads the current value of the transferred-to service contract line detail number from the output map to check if it is blank |
| - | `JBSbatKKAdChgAddDataCst.isBlank(String)` | JBSbatKKAdChgAddDataCst | - | Internal utility to check if a string is null or blank |
| - | `outMap.setString(String, String)` | - | - | Sets a key-value pair in the output map (called 18 times total: 1 shared + 3 per service branch × 3 types) |

**Note:** This method is a pure data setter. It performs no database or SC/CBS calls. It only reads from and writes to the `JBSbatServiceInterfaceMap` interface object using `getString()` and `setString()` calls. The `isBlank()` utility method is a private helper on the same class.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Class: `JBSbatKKAdChgAddDataCst.execute()` | `JBSbatKKAdChgAddDataCst.execute()` -> `setNewKaisenTgSvkei(outMap, svcCd, ...)` | `setString` [-], `isBlank` [-] |

This method is called directly by `execute()` in the same class (`JBSbatKKAdChgAddDataCst`). No screen or batch entry points were found within 8 hops. The terminal operations from this method consist entirely of `setString()` calls (18 instances) and `isBlank()` checks (19 instances) — all operating on the in-memory `outMap` and local parameters.
