## 1. Role

### JBSbatKKRsvTokiHak.execute()

This method serves as the main processing entry point for updating service contract details for "eo Hikari Denwa" (eo Light Phone — a fiber-optic broadband service provided by K-Opticom) during the anticipated ticket issuance batch process. It acts as a bridge between the ticket-target record extraction (performed by its sibling class `JBSbatKKRsvTokiHakTgCst`) and the actual database registration of service contract information.

The method implements a validation-and-insert dispatch pattern: it first validates the input data through a single-item check, then performs primary key lookups on two critical tables — `KK_T_SVKEIUW_EOH_TEL` (service contract details for eo Light Phone) and `KK_T_SVC_KEI_UCWK` (service contract details). If the service contract exclusion control record exists, it proceeds to register the eo Light Phone contract details and the service contract details.

When the SOD (Service Order Data) issuance type code is anything other than "0" (no issuance), the method further branches to register progress information (with special item descriptors indicating start or end of service), error reasons, and full order information — effectively fulfilling a telecom service order. The method delegates all actual database writes to insert methods (`insertSvkeiuwEohTel`, `insertSvcKeiUcwk`, `insertPrg`, `insertIdoRsn`, `insertOdr`) while using select methods for reads, maintaining a clean separation between orchestration (this method) and data access (delegated methods).

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Batch: JBSbatKKRsvTokiHakTgCst | `JBSbatKKRsvTokiHakTgCst.execute()` → (internal orchestration, invokes service layer via framework) → `JBSbatKKRsvTokiHak.execute()` | `insertSvkeiuwEohTel [C] KK_T_SVKEIUW_EOH_TEL`, `insertSvcKeiUcwk [C] KK_T_SVC_KEI_UCWK`, `executeKK_T_SVKEI_EXC_CTRL_KK_UPDATE_001 [U] KK_T_SVKEI_EXC_CTRL`, `insertPrg [C] KK_T_PRG`, `insertIdoRsn [C] KK_T_IDO_RSN`, `insertOdr [C] KK_T_ODR_HAKKO_JOKEN, KK_T_ODR_INF_SKSI_WK`, `executeKK_T_SVKEIUW_EOH_TEL_PKSELECT [R] KK_T_SVKEIUW_EOH_TEL`, `executeKK_T_SVC_KEI_UCWK_PKSELECT [R] KK_T_SVC_KEI_UCWK`, `executeKK_T_SVKEI_EXC_CTRL_KK_SELECT_001 [R] KK_T_SVKEI_EXC_CTRL` |

**Note:** `JBSbatKKRsvTokiHak` is a dedicated batch business service class that does not appear to be directly called from any screen-level controller or CBS (Common Business Service). Its only known caller is `JBSbatKKRsvTokiHakTgCst`, which is the anticipated ticket extraction batch. The two classes work as a pair — `TgCst` extracts ticket targets and `JBSbatKKRsvTokiHak` processes them to create service contract records.
