Managing Treaty vs. Statutory WHT Rates in Oracle Fusion

Summary:

In our process, treaty rates are applicable only for a defined duration (based on agreement validity, documentation such as TRC, or negotiated terms). After the validity period expires, the system should automatically revert to the statutory WHT rate unless the treaty eligibility is renewed.

Additionally, treaty rates (For transactions where treaty agreements exist across countries) and may change over time due to renegotiations or updated agreements.

Our questions are:

• Is there a standard way in Fusion to maintain treaty rate with validity periods (start and end dates)?
• Can the system automatically switch from treaty rate to statutory rate once the treaty validity expires?
