**How classified:**

- **C (Create)**: Methods with names starting with `callEKK*` followed by an SC code pattern, and methods with `addSOD`/`tsuikabunAddSOD` that insert records into the order issuance option detail table. The `addSOD` method specifically creates SOD (Service Order Data) documents with the specified content code.
- **R (Read)**: Methods with names starting with `callEKK*`, `get*`, or similar read patterns that query service agreement data from the database. The SC codes (e.g., EKK0351A010SC) follow the pattern `EKK<NNNN><ABC>SC` where the numeric portion corresponds to specific service component tables.

| 10 | JKKHakkoSODCC | `opExecHakko` -> `opSetOdrCtrl` | `addSOD [C] KK_T_ODR_HAKKO_JOKEN` |

**Terminal operations summary:** The method ultimately calls `addSOD` (Create) which inserts records into `KK_T_ODR_HAKKO_JOKEN` (Order Issuance Option Detail) with various `ODR_NAIYO_CD` codes (101-254). It calls `getSame_trn_no` (Read) from `KK_T_SAME_TRN_NO` for concurrent processing tracking.
