We have multiple business units (BUs) located in the US, UK, India, and France. The current requirement is to establish a threshold-based Purchase Price Reduction (PPR) approval rule, considering currency conversion rates. How should we proceed with this request?

For instance, if a payment is initiated with a base amount of $1000 across all BUs, it should be directed to Approver A's worklist. Payments exceeding $1000 should be routed to Approver B's worklist. It's important to note that for currencies other than USD, such as INR, the amount needs to be converted to USD for determining the appropriate approver.
