## 1. Role

### JBSbatKKKDDIAnkenIktTrkm.executeKK_T_KDDI_TJGWR_KJKS_PKINSERT()

This method performs a **primary-key-based insert** of KDDI other-carrier discount contract status inquiry records into the database table `KK_T_KDDI_TJGWR_KJKS` (KDDI Other Carrier Discount Contract Status Inquiry table). It is the final persistence step in the batch registration flow for KDDI referral case data, taking an array of 67 pre-collected field values and writing them as a single row via primary-key insert.

The method implements a **data-mapping-then-insert** pattern: it creates a `JBSbatCommonDBInterface` map object, populates all 67 fields by extracting values at fixed indices from the input `Object[]`, and delegates the actual SQL generation and execution to the `JBSbatSQLAccess` infrastructure via `insertByPrimaryKeys`. No conditional branching or business validation is performed at this level — it is a pure data-transport layer method.

Its role in the larger system is as a **leaf persistence method** called exclusively by `insertKDDITjgwrKjks()`, which assembles the field values from a `HashMap` retrieved during a batch read of the KDDI referral case table. This method does not branch by service type or condition; it always performs a single create operation on the same entity.

## 2. Processing Pattern (Detailed Business Logic)

```mermaid
flowchart TD
    START(["executeKK_T_KDDI_TJGWR_KJKS_PKINSERT setParam"]) --> CREATE_MAP["Create JBSbatCommonDBInterface setMap"]
    CREATE_MAP --> SET_FIELDS["Set 67 fields from setParam array to setMap"]
    SET_FIELDS --> INSERT_DB["DB Access - db_KK_T_KDDI_TJGWR_KJKS.insertByPrimaryKeys"]
    INSERT_DB --> END_NODE(["Return (void)"])
```

This method contains no conditional branches, loops, or error handling of its own. The processing flow is strictly sequential:

1. **Create mapping object** — A new `JBSbatCommonDBInterface` instance is instantiated to serve as the field-value container for the INSERT operation.
2. **Populate 67 fields** — Each field is populated sequentially by calling `setValue()` with the field name (as a string literal) and the corresponding element from the `setParam` array (indices 0 through 66). These fields cover the complete record structure of the `KK_T_KDDI_TJGWR_KJKS` table.
3. **Execute INSERT** — The `db_KK_T_KDDI_TJGWR_KJKS.insertByPrimaryKeys(setMap)` method is called, which uses the `JBSbatSQLAccess` framework to generate and execute an INSERT statement against the `KK_T_KDDI_TJGWR_KJKS` table using the populated field values. Primary keys are included in the insert (PK登録 — full-item registration).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `setParam` | `Object[]` | An array of 67 elements containing all field values for a single KDDI other-carrier discount contract status inquiry record. Index 0 is the auto-generated inquiry number; indices 1–12 are the applicant's personal information (name, kana, address, phone numbers); indices 13–36 cover the application timestamp, KDDI value code, referral carrier details, reception store info, agent details, KDDI reception type codes for telecom/internet/TV services, preferred contact date/time, current service usage information, privacy consent code, and KOPT/KDDI promotional codes; indices 37–46 cover out-of-region reception store, inquiry status, response completion date, current contract status codes, order result code, and NG reason code; indices 47–53 are application document numbers, information linkage department, callback info, and KOPT notes; indices 54–66 are audit trail fields (add/update/delete timestamps, operator accounts, transaction IDs, usage dates, and invalidation flag). |

**Instance fields read by this method:**

| Field Name | Type | Business Description |
|-----------|------|---------------------|
| `db_KK_T_KDDI_TJGWR_KJKS` | `JBSbatSQLAccess` | Database access delegate initialized with the `KK_T_KDDI_TJGWR_KJKS` table name. Used to execute the primary-key insert. |

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| C | `JBSbatSQLAccess.insertByPrimaryKeys` | - | `KK_T_KDDI_TJGWR_KJKS` | Performs a primary-key-based INSERT of a KDDI other-carrier discount contract status inquiry record with all 67 fields populated from the `setParam` array. This is a full-item registration (全項目登録) creating a new row in the inquiry status table. |
| U | `JBSbatCommonDBInterface.setValue` | - | In-memory | Sets 67 field-name/value pairs on the `JBSbatCommonDBInterface` map object, preparing the data payload for the INSERT operation. Each call maps a database column name to the corresponding value from the `setParam` array. |

**CRUD Classification Rationale:**
- **C** (`insertByPrimaryKeys`): The method name explicitly indicates a Create operation. It inserts a complete record with all primary key fields populated — this is a true INSERT, not an upsert or merge.
- **U** (`setValue`): While technically a field assignment rather than a database update, the `setValue` calls transform the raw `Object[]` into a structured field map. Classified as Update because it mutates the state of the `setMap` object, but it is an in-memory operation, not a DB update.

## 5. Dependency Trace

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

No screen/batch entry points found within 8 hops. Direct callers found: 1 methods.
Terminal operations from this method: `insertByPrimaryKeys` [C], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U], `setValue` [U]

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: `insertKDDITjgwrKjks` | `insertKDDITjgwrKjks(rsMap)` -> `executeKK_T_KDDI_TJGWR_KJKS_PKINSERT(setParamIns)` | `insertByPrimaryKeys [C] KK_T_KDDI_TJGWR_KJKS` |

**Caller details:**

The direct caller `insertKDDITjgwrKjks(HashMap rsMap)` is a **batch method** within the same class (`JBSbatKKKDDIAnkenIktTrkm`). It prepares a `Object[67]` array (`setParamIns`) by populating each element from the input `rsMap` (which contains KDDI referral case record data read from a batch query), generating the inquiry number via `JKKBatCommon.getFormatedNextSeq()`, and then invoking `executeKK_T_KDDI_TJGWR_KJKS_PKINSERT(setParamIns)` to persist the record. The `insertKDDITjgwrKjks` method itself is called from line 269 of this class, likely from a batch processing loop that iterates over KDDI referral case records.
