## 1. Role

### KKW02504SFLogic.storeGetDataInit()

This method performs the **initial screen data bean setup** for the "My Homepage Information Change" screen in the K-Opticom customer contract management system. It is invoked by `actionInit()` immediately upon screen entry to populate all form fields with their current values and derive display-state flags from the application's data bean context. The method operates in two major business phases: first, it reads sub-option service status indicators — specifically whether the subscriber's **Homepage Capacity** has been added and whether **Access Analysis** is active — by inspecting update-datetime fields. Second, it branches on the **process division** (`trandiv`) to set up different display data: for **Change** (`OP_TRAN_DIV_CHGE = "03"`), it retrieves the previous capacity value, zero-pads it via `fillZero`, resolves the matching pulldown index for both capacity and access analysis, and ensures a domain name is set; for **Termination** (`OP_TRAN_DIV_DSL = "04"`), it fetches the operational date and extracts year, month, and day components to pre-fill the service end date fields. This method follows a **delegation and data bean routing pattern**, using `X31SDataBeanAccess.sendMessageString` for scalar values and `X31SDataBeanAccessArray.getDataBeanArray` for list-backed pulldown components.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `KKW02504SFLogic` | `KKW02504SFLogic.actionInit` -> `storeGetDataInit` | `sendMessageString [R] DataBean`, `fillZero [-]`, `getOpeDate [R]` |

**Notes:** This method is called directly from `KKW02504SFLogic.actionInit()` (line 336) as the initialization routine when the My Homepage Information Change screen first loads. There are no external screen entry points (e.g., `KKSV*` screens) within 8 hops — the caller is internal to the same logic class. The method's terminal operations are all data bean reads/writes and utility calls (no direct database or SC invocations).
