## 1. Role

### JBSbatKKDelRun.updateDelTrnJssiDtm()

This method serves as the **delete transaction date/time routing dispatcher** within the K-Optimco batch deletion processing pipeline (`JBSbatKKDelRun`). Its business purpose is to **route a deletion request to the appropriate sub-handler based on the delete target type** (`delTrgtSbt`). The method receives a single input map carrying a `DEL_TRGT_SBT` key that identifies which class of entity the batch is attempting to delete. Based on the value of this code, the method dispatches to one of four specialized deletion handlers: customer deletion (`updateDelTrnJssiDtmCust`), service contract deletion (`updateDelTrnJssiDtmSvcKei`), service contract detail deletion (`updateDelTrnJssiDtmSvkeiuw`), or optional service contract deletion (`updateDelTrnJssiDtmOpsvkei`). It implements the **routing/dispatch design pattern**, using a switch-by-value chain to direct work to domain-specific handlers. If the `delTrgtSbt` value does not match any known category, the method logs a business error (`EKKB0130CE`) and raises a `JBSbatBusinessError` exception to abort the batch operation. This method is an internal orchestration step within the batch deletion workflow, called by `JBSbatKKDelRun.execute()`.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `inMap` | `JBSbatServiceInterfaceMap` | Input message carrying the batch deletion request. Specifically contains the `DEL_TRGT_SBT` key (a String code) that identifies the type of entity to be deleted — e.g., "11" for eoID, "01" for ISP Authentication ID, "17" for SIP User ID. This single field determines which of the four deletion sub-handlers is invoked. |
| — | `super.commonItem` | `JBSbatCommonItem` (inherited) | Shared batch processing context. The method reads `commonItem.getLogPrint()` for error logging and calls `commonItem.setErrFlg(true)` when setting the error flag on the error path. |

## 6. Per-Branch Detail Blocks

**Block 1** — [IF/ELSE-IF/ELSE CHAIN] `(delTrgtSbt-based routing)` (L861)

> The method begins by extracting the delete target type code from the input map, then branches through a cascading if/else-if chain. Each branch identifies a class of entities that share a common deletion sub-handler.

| # | Type | Code |
|---|------|------|
| 1 | SET | `delTrgtSbt = inMap.getString(JBSbatKKIFM161.DEL_TRGT_SBT)` // Extract delete target type from input map [-> `JBSbatKKIFM161.DEL_TRGT_SBT` = `"DEL_TRGT_SBT"`] |

**Block 1.1** — [IF] `(Customer deletion: eoID or Nickname)` (L869) [DEL_TRGT_SBT_EOID="11", DEL_TRGT_SBT_NKNAME="12"]

> If the delete target is the customer entity itself (identified by eoID code "11" or Nickname code "12"), route to the customer deletion handler.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_EOID)` // Check for eoID [-> `"11"`] |
| 2 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_NKNAME)` // Check for Nickname [-> `"12"`] |
| 3 | CALL | `updateDelTrnJssiDtmCust(inMap)` // Handle customer deletion |

**Block 1.2** — [ELSE-IF] `(Service contract deletion: ISP/PPP/ADSL AuthID)` (L879) [DEL_TRGT_SBT_ISP_NINSYO_ID="01", DEL_TRGT_SBT_PPP_NINSHO_ID="06", DEL_TRGT_SBT_ADSL_NINSHO_ID="16"]

> If the delete target is a service contract (identified by ISP Authentication ID "01", PPP Authentication ID "06", or ADSL Authentication ID "16"), route to the service contract deletion handler.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_PPP_NINSHO_ID)` // Check for PPP AuthID [-> `"06"`] |
| 2 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_ISP_NINSYO_ID)` // Check for ISP AuthID [-> `"01"`] |
| 3 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_ADSL_NINSHO_ID)` // Check for ADSL AuthID [-> `"16"`] |
| 4 | CALL | `updateDelTrnJssiDtmSvcKei(inMap)` // Handle service contract deletion |

**Block 1.3** — [ELSE-IF] `(Service contract detail deletion: SIP/Old ISP/OABJ)` (L890) [DEL_TRGT_SBT_SIP_USER_ID="17", DEL_TRGT_SBT_ISP_NINSYO_ID_OLD="02", DEL_TRGT_SBT_OABJ_TELNO="09"]

> If the delete target is a service contract detail item (SIP User ID "17", old-format ISP AuthID "02", or OABJ phone number "09"), route to the service contract detail deletion handler.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_SIP_USER_ID)` // Check for SIP User ID [-> `"17"`] |
| 2 | EXEC | `delTrgtSbt.equals(DEL_TRGT_SBT_ISP_NINSYO_ID_OLD)` // Check for Old ISP AuthID [-> `"02"`] |

**Block 1.4** — [ELSE-IF] `(Optional service contract deletion via helper)` (L899) [isDelOpsvkei helper]

> If `isDelOpsvkei(delTrgtSbt)` returns true, the delete target is an optional service contract. The `isDelOpsvkei` method internally checks for these codes: "03" (MLAD), "04" (MailAlias), "15" (POPID), "07" (URL), "14" (Web ID), "05" (Mailing List), "08" (Fixed IP), "10" (050 Phone), "18" (Multi-session AuthID).

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `isDelOpsvkei(delTrgtSbt)` // Check if optional service contract type |
| 2 | CALL | `updateDelTrnJssiDtmOpsvkei(inMap)` // Handle optional service contract deletion |

**Block 1.5** — [ELSE] `(Error: unhandled delete target type)` (L906)

> If none of the known `delTrgtSbt` codes matched, the method logs a business error, sets the error flag, and throws a `JBSbatBusinessError` exception. This is a fail-fast path that aborts the batch operation for unrecognized deletion target types.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `commonItem.getLogPrint().printBusinessErrorLog(JPCBatchMessageConstant.EKKB0130CE, new String[]{"消去対象種類"})` // Log error: unrecognized delete target type (Japanese: "Delete Target Type") |
| 2 | EXEC | `super.commonItem.setErrFlg(true)` // Set error flag in shared batch context |
| 3 | EXEC | `throw new JBSbatBusinessError()` // Abort the batch operation with a business error |
