## 1. Role

### JFUDslNetOpSvcKeiCC.jdgHiChrg()

This method performs the non-charge determination processing (non-課金判定処理) for DSL network option and sub-option services during contract cancellation flows. In the K-Opticom eCustomer base system, when a customer cancels an optional add-on service (such as Mail Address WEB Cancellation, Mail WBS Cancellation, IPv6, or My Home Page capacity reduction), the system must determine whether any termination-period billing (解約時課金) applies and calculate the final billing end date.

The method implements a **routing/dispatch pattern** based on the `svcDiv` parameter. When `svcDiv` equals "1", it processes the **Option Service** (オプションサービス) branch, retrieving data from the `opInfoMap`. Otherwise, it processes the **Sub-Option Service** (サブオプションサービス) branch using `sbopInfoMap`. This branching allows a single entry point to handle both top-level and nested optional service cancellation billing logic.

Within each branch, the method follows a **delegation pattern**: it first queries the Option Service Agreement Conference SC (EKK0081A010) to obtain the service billing start date (`svcChrgStaYmd`), then checks whether the service is in active progress or halted status. If so, it delegates to `JKKBpCommon.jdgHiChrg(trgtData)` — a shared non-charge determination utility — passing calculated service dates and a cancellation-type flag ("2" for option, "3" for sub-option). If the service is not in active/halted status, it computes the billing end date as the day before the operation date and marks no termination charge.

The method serves as a **shared utility** called by 14+ direct callers across screen logic classes (KKA14201SFLogic, KKA17001SFLogic, KKW02501SFLogic, KKW02504SFLogic, KKW02507SFLogic) and CBS classes (JKKEmailInfoChgCfmCC, JKKOpsvckeiDslCC, JKKOptHiChrgJdgCC), making it a central billing determination point for DSL option service cancellations throughout the system.

**CRITICAL — Constant Resolution:**

| Constant | Value | Business Meaning |
|----------|-------|-----------------|
| `JFUStrConst.CD00037_100` | `"100"` | Service in progress (サービス提供中) — the option/sub-option service is actively being provided |
| `JFUStrConst.CD00037_210` | `"210"` | Service halted (サービス休止中) — the service is temporarily suspended but not cancelled |
| `JFUStrConst.CD00002_0` | `"0"` | No termination charge (解約時課金なし) — no additional billing applies upon contract cancellation |
| `svcDiv` == `"1"` | — | Option Service (オプション) — top-level optional service |
| `svcDiv` else | — | Sub-Option Service (サブオプション) — nested optional service |
| `dslSbtFlg` = `"2"` | — | Option cancellation type flag — distinguishes option service cancellation |
| `dslSbtFlg` = `"3"` | — | Sub-option cancellation type flag — distinguishes sub-option service cancellation |

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `handle` | `SessionHandle` | Database session handle for executing service component (SC) calls. Carries the transactional context including connection and security information. |
| 2 | `param` | `IRequestParameterReadWrite` | Request parameter object carrying the request payload. Used to initialize and retrieve data for the Option Service Agreement Conference SC (EKK0081A010) via `param.getData()` and `initData()`/`setInMapEKK0081A010()`. |
| 3 | `fixedText` | `String` | Service message identifier / template key used to locate the correct data block within the request parameter. Maps to a specific service contract message block (EKK0081A010). |
| 4 | `opInfoMap` | `HashMap` | Operation info map carrying the **Option Service** (オプションサービス) contract details. Contains fields such as `OP_SVC_KEI_STAT` (option service contract status, code CD00037), `OP_SVC_CD` (option service code), `SVC_STAYMD` (service usage start date), and `SVC_KEI_NO` (service detail number). |
| 5 | `sbopInfoMap` | `HashMap` | Sub-Option Service (サブオプションサービス) contract details map. Contains fields such as `SBOP_SVC_KEI_STAT` (sub-option service contract status, code CD00037), and `SVC_STAYMD` (sub-option service usage start date). |
| 6 | `svcDiv` | `String` | Service division identifier that routes the processing flow. Value `"1"` selects the Option Service branch; any other value selects the Sub-Option Service branch. This is the primary routing parameter for the method. |

**External State:**
- The method reads operation date via `JFUBPCommon.getOpeDate(null)`, which provides the current business operation date (e.g., the cancellation request date).
- The method reads the service contract status from `opInfoMap` and `sbopInfoMap` which are populated by prior caller logic.

**Block 2** — [CALL] EKK0081A010 — Service Agreement Conference (L2754–L2766)

> The Option Service Agreement Conference SC is initialized, populated with the service contract number, executed, and the service billing start date is extracted from the result.

| # | Type | Code | Business Description |
|---|------|------|---------------------|

**Block 3** — [IF] Option Service Branch: `svcDiv` equals "1" (L2768)

> If this is an Option Service (オプション), determine the billing outcome based on the current service status.

| # | Type | Code |
|---|------|------|
| 1 | SET | `trgtDataOp = new HashMap()` // Target data map for Option non-charge determination |
| 2 | IF | Check service status (L2771): `JFUStrConst.CD00037_100` ("100" = Service in progress / サービス提供中) OR `JFUStrConst.CD00037_210` ("210" = Service halted / サービス休止中) |

**Block 3.1** — [nested IF true] Service in progress or halted — Option Service (L2772–L2794)

> When the option service is actively provided or temporarily halted, calculate billing dates through the non-charge determination utility. The method builds a target data map with the service billing start date, cancellation-type flag "2" (オプション解約種別フラグ), option service code, option service usage start/end dates, then delegates to `JKKBpCommon.jdgHiChrg()` for the determination. Results are mapped back to the return map.

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | SET | `trgtDataOp.put("svcKeiChrgStaYmd", svcChrgStaYmd)` // Service contract billing start date (サービス契約サービス課金開始日) |

| 7 | SET | `returnMap.put(EKK0351C250CBSMsg.SVC_CHRG_ENDYMD, resMap.get(OUT_PARAM_SVC_CHRG_ENDYMD))` // Service billing end date (サービス課金終了年月日) |
| 8 | SET | `returnMap.put(EKK0351C250CBSMsg.DSLJI_CHRG_FLG, resMap.get(OUT_PARAM_CHRGFLG))` // Termination charge flag (解約時課金フラグ) |

**Block 3.2** — [IF false] Service not in progress or halted — Option Service (L2795–L2800)

> When the option service is NOT in active/halted status (e.g., already cancelled or never started), set the billing end date to the day before the operation date and mark no termination charge.

| # | Type | Code | Business Description |
|---|------|------|---------------------|

**Block 4** — [ELSE] Sub-Option Service Branch (L2804)

> When `svcDiv` is not "1", this is a Sub-Option Service (サブオプション) branch. The logic mirrors the Option branch but uses `sbopInfoMap` and Sub-Option-specific CBS messages.

| # | Type | Code | Business Description |
|---|------|------|---------------------|
| 1 | IF | Check service status (L2807): `JFUStrConst.CD00037_100` ("100" = Service in progress / サービス提供中) OR `JFUStrConst.CD00037_210` ("210" = Service halted / サービス休止中) |

> **NOTE:** There is a potential bug on line 2808: the code reads `opInfoMap.get(EKK0401A010CBSMsg1List.SBOP_SVC_KEI_STAT)` instead of `sbopInfoMap.get(...)`. The second condition uses `opInfoMap` while it should reference `sbopInfoMap` for the sub-option status field. This means the sub-option service status check may read the wrong map, potentially causing incorrect billing determination for sub-option services.

**Block 4.1** — [nested IF true] Service in progress or halted — Sub-Option Service (L2809–L2832)

> When the sub-option service is actively provided or temporarily halted, calculate billing through the non-charge determination utility using sub-option-specific data: billing start date, cancellation-type flag "3" (サブオプション解約種別フラグ), sub-option service usage start/end dates.
