## 1. Role

### KKA16701SFLogic.searchCourseRk()

This method performs the **course history list search** for a customer in the K-Opticom telecom OSS/BSS system. "Course" (コース) refers to a customer's current service plan/package — a core concept in the Japanese ISP domain where customers subscribe to layered services (Internet, TV, hosting, etc.) and can change their plan at any time. The method orchestrates the complete lifecycle of a course history query: it sets up the operational date context, invokes the backend service (`KKSV0394`) that retrieves the customer's service contract history, handles any errors, and then maps the returned data back to the front-end data bean.

The method implements a **delegation pattern** — it prepares input parameters, delegates the actual data retrieval to the `KKSV0394` screen service via `invokeService`, and then processes the results. It also implements a **conditional display pattern** where special UI control flags are set based on the customer's service attributes. Specifically, if the customer has an active FTTH (Fiber-to-the-Home) Internet service with course change history (異動区分 = "00009"), is not in a mansion (apartment) plan, has a service status >= 100, and is eligible for course change fee discounts, the method configures special button flags to display a discount eligibility screen (ボタン制御フラグ = "3", 戻るボタン制御フラグ = "3").

Its role in the larger system is that of a **screen-level orchestrator** called from `forwardBack()` and `init()` within the same logic class. It serves as the search-and-display handler for the course history list screen, enabling customers and operators to view the complete history of plan changes for a given customer account.

**Processing flow summary:**

1. **Setup phase**: Initialize HashMaps for input, output, and parameter data passing. Create the `KKSV0394_KKSV0394OPDBMapper` instance and retrieve the service form bean. Set the current operation date into the data bean using `JCCWebCommon.getOpeDate()`.

2. **Service invocation**: Prepare the input map by setting the use case ID to `"KKSV0394"`, then invoke the backend service via `invokeService()`.

3. **Error handling**: If the service returns an error (`msgResult` is not null), set the message info via `JCCWebCommon.setMessageInfo()` and return `false`.

4. **Result mapping**: On successful service execution, map the output data back into the parameter bean via `mapper.getKKSV039401CC()`.

5. **Popup branch**: If `setPopupValue()` returns `true` (popup mode), set the back button control flag to `"0"` (hide back button) and return `true`.

6. **Customer data extraction**: In non-popup mode, extract customer details including movement type (異動区分), service code, mansion flag, service contract status, and discount auto-apply flag.

7. **Discount flag determination**: Determine whether the discount auto-apply exclusion flag is active by checking if the customer's discount excluded flag is null/empty (defaults to false) or explicitly equals "0" (false), otherwise true.

8. **Special display logic (v5.00.00 feature)**: If all of the following are true: service code is NET (`"01"`), mansion flag is `"0"`, movement type is `"00009"` (course change), service status >= 100, and course change fee discount display flag is `"1"` — then configure special UI controls to show the discount eligibility screen. Otherwise, set normal UI controls.

9. **Forward**: Set the forward destination to screen `KKW02701` (course history) and return `true`.

| - | (none - instance method on page logic) | - | - |

**Instance fields and external state read by this method:**

## 4. CRUD Operations / Called Services

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

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `JCCWebCommon.getOpeDate` | JCCBPCommon | KK_T_OPERATIONS (operation date reference) | Retrieves the current operation date for the session context |
| C | `KKSV0394_KKSV0394OPDBMapper.setKKSV039401CC` | KKSV039401 | - | Sets the input parameters for the KKSV0394 course history search service — populates inputMap with request data |
| C | `OneStopDataBeanAccess.sendMessageString` (TELEGRAM_INFO_USECASE_ID) | - | - | Sets the use case ID "KKSV0394" into paramMap to route the service call |
| - | `KKSV0394_KKSV0394OPDBMapper` invoke via `invokeService` | KKSV0394 | - | Invokes the KKSV0394 screen service that performs the course history list search |
| R | `KKSV0394_KKSV0394OPDBMapper.getKKSV039401CC` | KKSV039401 | - | Maps the service output data back into the parameter bean after successful retrieval |
| - | `JCCWebCommon.setMessageInfo` | JKKAddSupportCC | - | Sets error message information from the service result into the UI context |
| R | `X31SDataBeanAccess.getDataBeanArray` | - | - | Retrieves the customer contract entity list (HKTGI_CUST_KEI_HKTGI_LIST) from the data bean |
| R | `X31SDataBeanAccess.sendMessageString` | - | - | Reads various string fields from data beans: movement type (異動区分), service code (サービスコード), mansion flag (マンションフラグ), service contract status (サービス契約ステータス), discount excluded flag (割引自動適用対象外フラグ), course change fee discount display (コース変更手数料減額表示) |
| R | `X31SDataBeanAccess.sendMessageBoolean` | - | - | Reads boolean fields from the data bean for discount auto-apply flag |
| - | `X31SDataBeanAccess.sendMessageString` (SET) | - | - | Writes control flags: button control flag (ボタン制御フラグ), back button control flag (戻るボタン制御フラグ) |
| - | `X31SDataBeanAccess.sendMessageBoolean` (SET) | - | - | Writes discount auto-apply exclusion flag (割引自動適用対象外フラグ) |
| - | `KKA16701SFLogic.setForwardInfo` | KKA16701SF | - | Sets the forward destination screen to KKW02701 (course history list) |
| - | `KKA16701SFLogic.setPopupValue` | KKA16701SF | - | Checks whether the current execution context is in popup mode |

**Note:** The primary business data access is performed through the `KKSV0394` screen service. This method acts as a webview orchestrator — it does not directly access database tables. The actual CRUD operations on entity tables (customer contracts, service plans, movement history) are contained within the KKSV0394 service component.

## 5. Dependency Trace

### Callers of searchCourseRk():

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Logic: `KKA16701SFLogic.forwardBack()` | `forwardBack()` -> `searchCourseRk()` | `KKSV0394` course history list search |
| 2 | Logic: `KKA16701SFLogic.init()` | `init()` -> `searchCourseRk()` | `KKSV0394` course history list search |

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

No screen/batch entry points found within 8 hops. Direct callers found: 2 methods.
Terminal operations from this method: `setForwardInfo` [-], `sendMessageString` (multiple), `sendMessageBoolean` (multiple), `getKKSV039401CC` [-], `setKKSV039401CC` [-].

**Call chain details:**

1. **`KKA16701SFLogic.forwardBack()`** — This is a navigation handler within the same screen logic. It determines the forward/backward navigation flow for the course history screen. It calls `searchCourseRk()` to refresh the course history list data during navigation transitions.

2. **`KKA16701SFLogic.init()`** — This is the initialization entry point for the `KKA16701SF` screen logic. It calls `searchCourseRk()` during screen initialization to populate the course history list for display.

Both callers are internal to the same `KKA16701SFLogic` class and operate in the webview/controller layer.
