## 1. Role

### JKKKikiIchiranKkOpKyUpdCC.execKikiOptSvcKeiUpd()

This method is the central update orchestrator for **Equipment Option Service Contracts** (機器オプションサービス契約). It handles the full lifecycle of modifying an existing equipment option service contract record — whether the equipment is in a state of DSL (解約/deregistered), cancellation (キャンセル/cancelled), contracted but not yet in-service (締結済/contracted), or actively in service provision (サービス提供中/service providing).

The method implements a **conditional routing pattern** that branches based on the current service status of the equipment option contract. When the equipment status is DSL (910) or Cancel (920), it routes to a create path (re-registering the contract via `execKikiOptSvcKeiCreate`). For active contracts, it handles three distinct scenarios: (a) cancellation retraction when a DSL date is cleared, (b) price plan changes when the pricing code differs, and (c) service start processing when the contract reaches a contracted status under specific conditions.

Its role in the larger system is a **shared CBS common component method** called by DSL-related operation methods (e.g., `execKikiOptSvcKeiUpdDsl`, `execKikiOptSvcKeiUpdDslTnmt`). It serves as the single entry point for all equipment option service contract updates, ensuring consistent transaction handling across all service type branches.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `handle` | `SessionHandle` | Database session handle used for all CBS/SC calls and transaction management. |
| 2 | `scCall` | `ServiceComponentRequestInvoker` | Service component invocation bridge used to call downstream CBS (e.g., `execEKK0591B003`, `execEKK2811A010`). |
| 3 | `param` | `IRequestParameterReadWrite` | Request parameter object for reading/writing data at the screen-to-CBS boundary. Used to retrieve `ccMsg` map, set update timestamps, and pass data through the processing pipeline. |
| 4 | `dataMapKey` | `String` | Key identifier for locating the data map within the request parameters. Used to access the `ccMsg` HashMap that carries screen-level flags (e.g., `func_code`, `rt_new_pcrs_aply_flg`). |
| 5 | `temporaryData` | `HashMap<String, Object>` | Temporary data map that holds intermediate processing state across CBS calls. Contains DSL date information, service codes, pricing codes, and the update status (`updStat`). Also receives the `KikiRntaiKeiChgechuFlg` (equipment bundled contract change-in-progress flag). |
| 6 | `ekk2811a010Msg` | `CAANMsg` | CBS message object carrying the equipment option service contract data from the input screen/query. Provides service status (`KKOP_SVC_KEI_STAT`), pricing code (`PCRS_CD`), last update timestamp (`LAST_UPD_DTM`), and service contract number (`KKOP_SVC_KEI_NO`). |

**Instance fields referenced:** None directly — all constants are `private static final` within the class.
