## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `isErrClear` | `boolean` | Controls whether screen errors should be cleared before validation. true: clear existing page errors and reset the net display status (画面のエラーをクリアしてからチェックするかしないか判定するフラグ). false: retain existing errors. This is used when the method is called from smpAgntGet or tabletAgntGet to avoid clearing errors that belong to the calling context. |
| 2 | `isCallTabletAgntGet` | `boolean` | Indicates whether this method is called from tabletAgntGet (tabletAgntGetから呼出された場合はtrue). When true, the tablet terminal buyer name validation is skipped because the agent screen already performed this check. This prevents duplicate error messages when navigation flows between agent screens. |
| 3 | `isCallSmpAgntGet` | `boolean` | Indicates whether this method is called from smpAgntGet (ストリーミングメディアプレイヤー画面から呼出された場合). When true, the streaming media player buyer name validation is skipped because the streaming player agent screen already performed this check. Added in ANK-3987-00-00 for Netflix integration. |
