## 1. Role

### KKW12601SFLogic.setParamAndSeni()

This method serves as the shared page transition handler for the Invoiced Receipt List screen (KKW12601), preparing all data required to navigate to either the Invoiced Receipt Detail Update screen (KKW12602) or the Invoiced Receipt Detail Confirmation screen (KKW12604). It implements a data-accumulation and screen-state-setting pattern: it reads the selected row from the current screen's data grid, validates that the row has not already been sent (when performing an update operation), copies all search filter criteria from the current screen into an inheritance map for the self-screen (return destination), accumulates the transaction division and selected receipt identifier into a next-screen map, and registers both maps as screen information via the shared web common utility. Its role in the larger system is as the central coordination method between the list view (KKW12601) and its child detail screens (KKW12602/KKW12604), ensuring consistent data flow across screen transitions without screen-crossing dependencies. The method handles two branches: (1) when `tran_div` equals "2" (detailed update), it performs a pre-check to prevent updates to already-transmitted receipts; (2) for all cases, it builds complete inheritance data structures and sets up screen navigation state.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `tran_div` | `String` | Transaction division code that determines the type of operation on the selected invoiced receipt record. Value `"1"` means detailed view (display only), value `"2"` means detailed update (allow modifications). This value is forwarded to the next screen so it knows whether to render the UI in view-only or edit mode. |

**Instance fields / external state read:**

| Source | Description |
|--------|-------------|
| `super.getServiceFormBean()` | Returns the service form DataBean (X31SDataBeanAccess) containing the current screen's data grid, selection state, and search filter inputs |
| `super.getCommonInfoBean()` | Returns the shared common info bean used to set the next screen ID for cross-screen navigation |
| `this` | The logic instance itself, passed to JCCWebCommon for screen state management |

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `KKW12601SFLogic.actionShokaiDtl()` | `actionShokaiDtl()` -> `setParamAndSeni(tran_div)` | `printLog` (log), `setScreenInfo` (state), `setScreenId` (state) |
| 2 | `KKW12601SFLogic.actionUpdDtl()` | `actionUpdDtl()` -> `setParamAndSeni(tran_div)` | `printLog` (log), `setScreenInfo` (state), `setScreenId` (state) |

**Call chain details:**

- **`actionShokaiDtl()`**: Called from screen KKW12601 when the user clicks the "Detail View" (show) button on a selected invoiced receipt row. Passes `TRAN_DIV_DTL = "1"` to indicate read-only detail display. The method navigates to screen KKW12602 (detail update screen) in view-only mode.

- **`actionUpdDtl()`**: Called from screen KKW12601 when the user clicks the "Detail Update" button on a selected invoiced receipt row. Passes `TRAN_DIV_UPD = "2"` to indicate update mode. If the selected record has already been transmitted (send_dtm is set), an error message is displayed and navigation is blocked. Otherwise, it navigates to screen KKW12604 (detail confirmation screen for updates).

No batch entry points. This method is exclusively a screen-to-screen coordination method in the web view layer.
