## 1. Role

### JKKAdchgHakkoSODCC.jdgIpv6()

This method performs **IPv6 Address Determination Processing** (IPv6判定処理) as part of Fujitsu's eo Hikari telecom order fulfillment system. It determines whether an IPv6-capable router should be shipped and an IPv6 Service Order Data (SOD) should be issued based on the customer's order type and device provisioning state. The method acts as a **routing dispatcher**: it queries device provision service contracts filtered by service code "C014" (BBR, the broadband router service), iterates over the returned contract records, applies a cascade of business-rule filters (service status, order division type, manufacturing metadata), and for each record that passes all filters, sets up the instance fields and invokes `hakkouIpv6` to actually generate the IPv6 SOD. It handles multiple service patterns encoded in `sod_pattern_ipv6`: pattern 1 corresponds to IPv6 registration, pattern 2 to IPv6 change, and pattern 3 to IPv6 cancellation — each pattern drives different filtering behavior for the service status check and the order division (ido_div) matching. The method implements a **delegation pattern** where it performs pre-processing (filtering, field preparation) and delegates the actual SOD issuance to `hakkouIpv6`.

|----|---------------|------|---------------------|
| 1 | `handle` | `SessionHandle` | Session manager handle carrying database connection and transaction context used across all service component calls |
| 2 | `param` | `IRequestParameterReadWrite` | Request parameter object containing model group and control map — serves as the bidirectional data carrier for screen/business layer communication |
| 3 | `kei_ucwk_no_param` | `String` | Service detail work number — the internal contract line item tracking number. Used to match against returned device provision contract records when `ido_div` is not a new order (i.e., for changes, transfers, cancellations). In current usage, this is always passed as an empty string `""`, meaning it is not actively used as a filter. |

**Block 3** — [LOOP] `(iterate over device provision service contract records)` (L21344)

Loop through each CAANMsg returned from EKK0341B002SC, extracting and filtering device provision service contract records.

| # | Type | Code |
|---|------|------|
| 1 | SET | `i = 0; i < msgEKK0341B002SCList.length; i++` |
| 2 | EXEC | `eKK0341B002Hash = msgEKK0341B002SCList[i].getMsgData()` — Extract HashMap from CAANMsg |

| 17 | CALL | [Block 3.6 — shipping completion judgment] |
| 18 | CALL | [Block 3.7 — SOD issuance branch] |

**Block 3.1** — [IF] `(sod_pattern_ipv6 != 3 — status filter for non-cancellation)` [sod_pattern_ipv6 != 3] (L21352)

When `sod_pattern_ipv6` is NOT 3 (i.e., not a cancellation operation), filter device provision contract records by service status. Only active service states are kept: "010" (order received), "020" (approved), "030" (contracted), "100" (service provision in progress). If the record's status does not match any of these, it is skipped.

| # | Type | Code |
|---|------|------|
| 1 | IF | `this.sod_pattern_ipv6 != 3` |
| 2 | IF | `kktkStat != "100" AND kktkStat != "010" AND kktkStat != "020" AND kktkStat != "030"` |
| 3 | EXEC | `continue` — Skip non-active status records |

**Block 3.2** — [IF] `(ido_div != "00001" — new order check)` [IDO_DIV_NEW = "00001"] (L21397)

When the order division is NOT a new order ("00001"), additional filtering applies. If the order division IS option setup ("00031"), then the option service contract number from the query result must match the `op_svc_kei_no_param` parameter. This ensures that during option setup processing, only the specific IPv6 option contract being configured triggers SOD issuance.

| # | Type | Code |
|---|------|------|
| 1 | IF | `ido_div != IDO_DIV_NEW ("00001")` — Not a new order |
| 2 | IF | `ido_div == IDO_DIV_OPSETTE ("00031")` — Option setup case |
| 3 | IF | `check_op_kei_no != shkkaChr(op_svc_kei_no_param)` |
| 4 | EXEC | `continue` — Mismatched option contract number, skip |

**Block 3.3** — [IF] `(blank check on manufacturing number and model code)` (L21451)

Both the device manufacturing number (`kiki_seizo_no_ipv6`) and the indoor device model code (`taknkiki_model_cd_ipv6`) must be non-blank for the record to proceed. If either is missing, the device information is incomplete and the record is skipped.

| # | Type | Code |
|---|------|------|
| 1 | IF | `isBlank(kiki_seizo_no_ipv6) OR isBlank(taknkiki_model_cd_ipv6)` |
| 2 | EXEC | `continue` — Incomplete device info, skip |

**Block 3.4** — [ASSIGN] `(set IPv6 device fields and initialize arrays)` (L21457)

Assign the IPv6 device contract number and registration datetime to instance fields. Initialize the `kiki_seizo_no` and `taknkiki_model_cd` arrays (size 3, supporting up to 3 devices) if they are not yet allocated, storing the IPv6 device info at index 0.

| # | Type | Code |
|---|------|------|
| 1 | SET | `this.ipv6_kktk_svc_kei_no = temp_ipv6_kktk_svc_kei_no` — IPv6 device provision contract number |
| 2 | SET | `this.ipv6_kktk_svc_kei_gadtm = temp_ipv6_kktk_svc_kei_gadtm` — IPv6 device provision contract registration datetime |
| 3 | IF | `kiki_seizo_no == null OR kiki_seizo_no.length == 0` |
| 4 | SET | `kiki_seizo_no = new String[3]` — Initialize device manufacturing number array |
| 5 | SET | `kiki_seizo_no[0] = kiki_seizo_no_ipv6` |
| 6 | IF | `taknkiki_model_cd == null OR taknkiki_model_cd.length == 0` |
| 7 | SET | `taknkiki_model_cd = new String[3]` — Initialize device model code array |
| 8 | SET | `taknkiki_model_cd[0] = taknkiki_model_cd_ipv6` |

**Block 3.5** — [CALL] `(query device model master data)` (L21471)

Call `getTaknkikiM` to retrieve the device model master data, which includes the IPv6 compatibility flag. This determines whether the router model supports IPv6.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `taknkiki_model_m = getTaknkikiM(handle, param, taknkiki_model_cd_ipv6)` — Device model master data |
| 2 | IF | `taknkiki_model_m != null` |
| 3 | SET | `this.kiki_ipv6_taio_flg = shkkaChr(taknkiki_model_m.get(IPV6_TAIO_FLG))` — Device IPv6 support flag |

**Block 3.6** — [IF/ELSE] `(set IPv6 address confirmation flag)` (L21477)

Determine whether an IPv6 address has been definitively assigned. If `op_addr_ipv6` is blank, the address is not confirmed; otherwise, it is confirmed.

| # | Type | Code |
|---|------|------|
| 1 | IF | `isBlank(op_addr_ipv6)` |
| 2 | SET | `op_addr_kakutei_ipv6 = false` — IPv6 address not confirmed |
| 3 | ELSE | `op_addr_kakutei_ipv6 = true` — IPv6 address confirmed |

**Block 3.7** — [IF/ELSE] `(IPv6 device shipping completion judgment)` (L21487)

Determine whether the device should be shipped by checking both conditions: (1) the device has a manufacturing number (is a real product), AND (2) the device model supports IPv6 (`kiki_ipv6_taio_flg` equals "1", the TAIO support flag).

| # | Type | Code |
|---|------|------|
| 1 | IF | `!isBlank(kiki_seizo_no_ipv6) AND shkkaChr(kiki_ipv6_taio_flg) == IPV6_TAIO_FLG_TAIO ("1")` |
| 2 | SET | `kiki_shukka_sumi_ipv6 = true` — IPv6 device shipping completed (device exists and supports IPv6) |
| 3 | ELSE | `kiki_shukka_sumi_ipv6 = false` — IPv6 device not shipping (no manufacturing number or device does not support IPv6) |

**Block 3.8** — [IF] `(kiki_shukka_sumi_ipv6)` (L21496)

Only when the device is confirmed to be IPv6-capable and shipping-worthy does the method proceed to SOD issuance preparation.

| # | Type | Code |
|---|------|------|
| 1 | IF | `kiki_shukka_sumi_ipv6 == true` |
| 2 | CALL | [Block 3.8.1 — op_addr_kakutei_ipv6 check] |

**Block 3.8.1** — [IF] `(op_addr_kakutei_ipv6)` (L21500)

SOD issuance is only performed when BOTH the device shipping flag and the IPv6 address confirmation flag are true. This ensures that IPv6 SODs are only issued when the customer has a supported IPv6 device AND has been assigned a concrete IPv6 address. Sets up the array fields (contract numbers, registration datetimes) needed by `hakkouIpv6`.

| # | Type | Code |
|---|------|------|
| 1 | IF | `op_addr_kakutei_ipv6 == true` |
| 2 | IF | `kktk_svc_kei_no == null OR kktk_svc_kei_no.length < 1` |
| 3 | SET | `kktk_svc_kei_no = new String[1]` |
| 4 | SET | `kktk_svc_kei_no[0] = ipv6_kktk_svc_kei_no` |
| 5 | IF | `kktk_svc_kei_gadtm == null OR kktk_svc_kei_gadtm.length < 1` |
| 6 | SET | `kktk_svc_kei_gadtm = new String[1]` |
| 7 | SET | `kktk_svc_kei_gadtm[0] = ipv6_kktk_svc_kei_gadtm` |
| 8 | IF | `svc_kei_ucwk_no == null OR svc_kei_ucwk_no.length < 1` |
| 9 | SET | `svc_kei_ucwk_no = new String[1]` |
