## 1. Role

### JKKAdchgTelInfoChgCC.deleteSvcKeiUcwk()

This method performs the **logical deletion of service contract line items** (サービス契約内訳, *svc_kei_ucwk*) in the context of address change (住所変更, *juusho henskou*) processing within the e-Opticom customer base system. It handles two distinct business scenarios based on the type of telephone number change that occurred during the address transfer:

When the customer underwent a **same-number migration** (同番移転, *douban itkou*) — meaning the phone number was preserved during the address move — but a subsequent correction required a phone number change, this method locates and logically deletes **reservation-only** line items at the post-move address whose reservation effective date has not yet arrived. The business intent is to clean up provisional service contracts that were created for the new address but should not become active, since the customer's correction changed the associated phone number.

When the customer's phone number was **changed after a migration** (電番変更後訂正, *dentan henskou ato seisei*), this method fully cancels the service detail records at the post-move address and registers the cancellation completion status (進捗登録「キャンセル完了」) via the `addEKK1091D010` CBS call. Additionally, if the phone number is a legal-entity number (法人電話番号, *houjin denwabangou*) that includes an on-net port (網内番ポ, *mounai ban po*), it updates the entity classification in the phone number master table to reflect the legal entity code. This ensures the billing interface (料金IF, *ryoukin IF*) can properly process cancellation charges.

The method implements a **retry loop pattern** (using `existDeleteData`) that re-fetches the service detail list until no more deletable records remain, ensuring that cascading deletions (where deleting one record unlocks another) are handled iteratively. It also calls `telNoCancel()` upfront when the operation is not a same-number migration, which clears the line items before this method's main deletion logic.

## 6. Per-Branch Detail Blocks

**Block 1** — [IF] `(!isSameTelNo)` (L463)

When the operation is NOT a same-number migration, clear the line items (telephonenumber deregistration) before proceeding with the main deletion logic.

| # | Type | Code |
|---|------|------|
| 1 | CALL | `telNoCancel()` // Deregister line items before deletion — called when not a same-number migration |

**Block 2** — [Processing] Parameter extraction (L467-472)

Extract business data from the request parameter map and obtain the current operation date.

| # | Type | Code |
|---|------|------|
| 1 | SET | `param = getRequestParameter()` // Retrieve the request parameter map |
| 2 | SET | `svcKeiNo = param.get("svc_kei_no")` // Service contract number — parent identifier for service details |
| 3 | SET | `beforeSvcKeiUcwkNo = param.get("before_svc_kei_ucwk_no")` // Before-move (origin address) service detail work number |
| 4 | SET | `afterSvcKeiUcwkNo = param.get("after_svc_kei_ucwk_no")` // After-move (destination address) service detail work number |
| 5 | CALL | `opeDate = JCCBPCommon.getOpeDate(null)` // Current operation date for date-based filtering |

**Block 3** — [WHILE] `existDeleteData == true` (L473-533)

Retry loop: continues fetching and deleting service details until no more deletable records exist. This handles cascading deletions where deleting one record may unlock another.

| # | Type | Code |
|---|------|------|
| 1 | SET | `existDeleteData = true` // Initialize loop control flag |
| 2 | CALL | `kk0161_b004_list = getEKK0161B004(svcKeiNo)` // Fetch all service details for this contract |
| 3 | SET | `existDeleteData = false` // Reset flag; set to true when deletion occurs |
| 4 | EXEC | **for-each** `kk0161_b004_map : kk0161_b004_list` // Iterate through each service detail record |

**Block 3.1** — [IF] `ucwkState == "910" || ucwkState == "920"` (L484-485)

Skip records that are already in a cancelled state (910 = cancellation completed, 920 = deregistration completed). This is a no-op filter to avoid re-processing already-closed records.

| # | Type | Code |
|---|------|------|
| 1 | SET | `ucwkState = map.get(SVC_KEI_UCWK_STAT)` // Extract current work state code |
| 2 | EXEC | `continue` // Skip this record — already cancelled or deregistered (910=解約済, 920=キャンセル済) |

**Block 3.2** — [IF] `isSameTelNo == true` (L489)

**Same-number migration branch**: Only delete reservation-type line items at the destination address that have not yet taken effect.

> Javadoc context: 同番移転後に訂正で電番変更された場合は転居先の内訳に存在する予約データを削除する — When the phone number was corrected after a same-number migration, delete the reservation data existing at the destination's line items.

**Block 3.2.1** — [IF] `!beforeSvcKeiUcwkNo.equals(svc_kei_ucwk_no)` (L490-491)

Filter: only process records matching the before-move work number.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `continue` // Target exclusion — not the before-move record |

**Block 3.2.2** — [IF] `opeDate.compareTo(rsvAplyYmd) >= 0` (L493-494)

Filter: only process records where the reservation effective date is in the future. If the reservation date has already passed, the service is already active and should not be deleted.

| # | Type | Code |
|---|------|------|
| 1 | SET | `rsvAplyYmd = map.get(RSV_APLY_YMD)` // Reservation application date (予約適用年月日) |
| 2 | EXEC | `continue` // Target exclusion — reservation already effective (not a pending reservation) |

**Block 3.2.3** — [Processing] Logical deletion of reservation data (L497-500)

Perform the logical deletion of the reservation-type service detail at the destination address.

| # | Type | Code |
|---|------|------|
| 1 | SET | `geneAddDtm = map.get(GENE_ADD_DTM)` // Generation registration datetime (世代登録年月日時分秒) |
| 2 | CALL | `logicalDeleteSvcKeiUcwk(svc_kei_ucwk_no, geneAddDtm)` // Logical deletion — sets cancellation status and removes sub-type records |
| 3 | SET | `existDeleteData = true` // Signal that deletion occurred; loop continues if more records become available |

**Block 3.3** — [ELSE] `isSameTelNo == false` (L503)

**Number change after migration branch**: Fully cancel the service detail at the destination address, register cancellation completion, and update the phone number master if the number is a legal-entity on-net port number.

> Javadoc context: 電番変更後に訂正で再度電番変更された場合は転居先の内訳を削除する — When the phone number is corrected again after a phone number change, delete the destination's line items.

**Block 3.3.1** — [IF] `!afterSvcKeiUcwkNo.equals(svc_kei_ucwk_no)` (L504-505)

Filter: only process records matching the after-move work number.

| # | Type | Code |
|---|------|------|
| 1 | EXEC | `continue` // Target exclusion — not the after-move record |

**Block 3.3.2** — [Processing] Full cancellation (L508-511)

Cancel the DSL service detail and register the cancellation completion status.

| # | Type | Code |
|---|------|------|
| 1 | SET | `geneAddDtm = map.get(GENE_ADD_DTM)` // Generation registration datetime |
| 2 | CALL | `cancelDslSvcKeiUcwk(svc_kei_ucwk_no, geneAddDtm)` // Cancel and deregister the service detail via S/IF |
| 3 | CALL | `addEKK1091D010(svcKeiNo, "1201")` // Register progress: cancellation completion (進捗登録「キャンセル完了」) — required for billing interface to process cancellation charges |

**Block 3.3.3** — [Processing] Phone number master update for legal-entity on-net port (L515-531)

AN-4494 Step2 quality enhancement: When the phone number is associated with a legal entity and has an on-net port, update the phone number master's entity classification.

| 3 | EXEC | `condMap.clear()` // Clear condition map for reuse |
| 4 | SET | `condMap.put(COND_KEY_TELNO, kk0191_a010_map.get(TELNO))` // Set telephone number as query condition — COND_KEY_TELNO = "cond_key_telno" |

| 11 | IF | `if (monaiBmpUm == CD00002_UMU_1)` (L528-530) — On-net port is present, update phone number master to reflect legal entity classification |

**Block 3.3.3.1** — [IF] `monaiBmpUm == CD00002_UMU_1` (L528-530)

When on-net port is present (on-net PO present / 網内番ポ有), update the phone number master to set the individual/legal entity phone band code to "2" (Legal entity / 法人). This is required so that the billing interface can correctly process charges.
