## 1. Role

### JBSbatKKDelSavePrdKikData.initial()

This method performs **initial processing** for a batch job responsible for the **physical deletion of stored data that has exceeded its retention period** (保存期間経過データ物理削除). The business domain is personal data deletion and service contract lifecycle management within K-Opticom's telecommunications customer backbone system. As a retention-period-based data purge service, it ensures regulatory compliance by permanently removing customer data after its legally-defined storage period has elapsed.

The method acts as a **batch entry point** (shared utility called by the batch execution framework) that prepares the entire processing environment. It uses the **delegation pattern** — initializing `JBSbatSQLAccess` objects for over 40 database tables, each serving as a dedicated data access proxy for subsequent CRUD operations. It also implements **parameter routing** — parsing a comma-delimited `freeItem` string to extract the transaction number, deletion stop flag, file path, and multi-run count.

The method handles four primary conditional branches: (1) parsing the freeItem string to extract processing metadata including the run count for multi-run support (ANK-3141), (2) validating the maximum processing time parameter exists and throwing `EKKB0740CE` if missing, (3) validating the transaction number exists and throwing `EKKB0130CE` if null, and (4) querying the personal deletion work table to determine the maximum multi-processing branch number — critical for handling concurrent batch restarts. The `DELSTOP_CD` flag (`"1"`) allows the deletion process to be suppressed entirely, providing a manual override for safety.

### Constant Resolution

| Constant | Actual Value | Business Meaning |
|----------|-------------|------------------|
| `DELSTOP_CD` | `"1"` | Deletion suppression code — when `freeItems[1]` equals `"1"`, physical deletion is suppressed for safety |
| `DEL_RUN_UPPL_TIM` | `"KK_DEL_RUNUPPL_TIME"` | Work parameter key for the maximum processing time (in minutes) allowed for deletion operations |
| `JACStrConst.SEMI_COLON` | `";"` | Delimiter used to split the `freeItem` string into segments |

## 3. Parameter Analysis

## 5. Dependency Trace

This method is called by the batch execution framework through the `JBSbatBusinessService` inheritance hierarchy. As a batch service class that extends `JBSbatBusinessService`, the `initial()` method is invoked by the batch framework's processing pipeline before the main `execute()` method runs. The class follows the standard batch service pattern where `initial(JBSbatCommonItem)` is the template method hook for preparation.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: JBSbatKKDelSavePrdKikData | `JBSbatBusinessService.initial(commonItem)` -> `JBSbatKKDelSavePrdKikData.initial` | `executeKK_T_KJNIFDEL_WK_KK_SELECT_003 [R] KK_T_KJNIFDEL_WK` |

**Notes:** No other classes directly reference `JBSbatKKDelSavePrdKikData` or call its `initial()` method. This class is the entry point for the retention-period data physical deletion batch, orchestrated by the external batch scheduler/job engine which instantiates the class and calls `initial()` followed by `execute()`.

**Block 15** — IF `(freeItems[1] equals DELSTOP_CD)` (L1055–L1057)

> Checks if the deletion stop code is set to `"1"`. If true, sets the deletion suppression flag to prevent any actual deletion from occurring. This is a safety mechanism — operators can set this flag to disable the batch without modifying code.

| # | Type | Code |
|---|------|------|
| 1 | SET | `delStopFlg = true` |

**Block 15.1** — ELSE `[freeItems[1] != "1"]`

> If the deletion stop code is not `"1"`, the deletion flag remains at its default `false` value, allowing normal deletion processing.
