The processing flow follows five major phases:

**Phase 1 - Data Extraction and Early Exit Check (L11688–L11718):** Extracts SOD basic info, service contract info, and service contract detail info from the sodMap. Applies `shkkaMap()` to each map (a transformation/copy operation). Extracts key identifiers (sys_id, ido_div, svc_kei_no, svc_kei_ucwk_no). If the previous service contract number (`moto_svc_kei_ucwk_no`) is set, it takes precedence. If `svc_kei_ucwk_no` is blank or `telDslExe` is false, the method returns immediately with the input param unchanged.

**Phase 2 - Device and Contract Data Gathering (L11719–L11877):** Calls `getSame_trn_no()` to obtain a same-processing number for transaction grouping. Calls `callEKK0191A010SC()` to look up FTTH auth registration data and extract VA port number, VA device model code, VA device serial number, and VA device change number. Calls `callEKK0341B008SC()` to look up device provision service contracts. Builds a combined device list by merging VA devices with multi-function router devices (from `getMfrInfoByEKK0341B019`) and pre-transfer multi-function router devices (from `getMfrInfoOfBfKaisen`). Iterates through the device list to identify the appropriate device, setting device contract numbers, generation timestamps, and device type codes.

**Phase 3 - Instance Field Storage and OLS/MFR Processing (L11878–L12016):** Stores all gathered device information into instance fields as String[1] arrays. Calls `getEKK0251B001SC()` to obtain service contract line list data. If all device info is present (kktkSvcKeiNo, kktkGeneAddDtm, taknkikiModelCd, kikiSeizoNo all non-blank), checks if the device is a new VA or a change (not already in `va_kiki_list`). If not Radius-cancellation-completed and the device is not a pure MFR or is an HGW, checks whether OLS cancellation orders already exist via `isDslOrderExist2()`. If not, issues OLS setup/cancellation SODs (`ODR_NAIYO_CD_215` + `ODR_NAIYO_CD_216`). For HGW/MFR devices, queries equipment option services (`runEKK2811B010`) to determine if VA or BBR router services are associated, and issues appropriate cancellation SODs.

**Phase 4 - SIP/ENUM Cancellation Processing (L12017–L12302):** Checks whether tokki (temporary pause) orders already exist via `checkTokiOrderExist()`. If no tokki order exists, determines whether SIP cancellation SODs should be issued based on the `odr_exec_div` value and change conditions (phone number change, address change, existing DSL orders). If SIP cancellation is needed, issues SIP cancellation SODs (`ODR_NAIYO_CD_229` + `ODR_NAIYO_CD_230`). Then performs ENUM cancellation processing by re-querying FTTH auth data, checking if the original phone number is an internal number port (isMonaiBmp), and issuing ENUM cancellation SOD (`ODR_NAIYO_CD_266`) if applicable. For tokki registration scenarios, updates tokki info via `updItntokiInfo()` and issues SIP tokki registration SOD (`ODR_NAIYO_CD_220`). If SIP cancellation was issued and the phone number is an internal number port (not tokki-ordered), sets the phone number update flag (`result_updJudgeTelNo`).

**Phase 5 - Final SOD Issuance (L12324–L12435):** Always issues emergency notice/cancellation SOD (`ODR_NAIYO_CD_252`). If Radius cancellation has not been completed (`!isRadiusZumi`), issues Radius authentication cancellation SOD (`ODR_NAIYO_CD_204`) and sets the Radius-completed flag. Returns the updated param.
