## 5. Dependency Trace

This method has **no external callers**. It is referenced only within the bean's own data-type-bean infrastructure by `KKW01601SFBean`, which uses the bean to generate instances for the "Billing Contract History List" data-type component. The `KKW01601SFBean` creates a `KKW01601SF02DBean` instance to hold data for data-type-bean-type fields (data-type-bean class name "KKW01601SF02DBean").

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | `KKW01601SFBean` (data-type-bean infra) | `KKW01601SFBean` instantiates `KKW01601SF02DBean` for billing contract history list | No external CRUD endpoints -- all calls are self-bean getters |

**Note:** The only reference to this bean outside the class file is in `KKW01601SFBean` where the bean is instantiated as a data-type-bean instance for the "Billing Contract History List" (`rireki_seiky_list`).
