Generate HCM Rates fails for Global Transfer employees when Final Close Dt exist on prior assignment

Summary:

We are seeing a consistent pattern where some employees who undergo a Global Transfer fail in the Generate HCM Rates process. After investigation, the common data point is the presence of a populated Final Close Date (FCD) on the previous inactive payroll assignment. Employees with similar Global Transfer histories but without an FCD are processed successfully.

We are trying to understand:

1. Whether FCD is expected to be populated during a Global Transfer when the payroll relationship continues.
2. The relationship between Element Duration Dates, Final Close Date, and Generate HCM Rates balance/hour calculation.
3. Whether this could be connected to rate definitions configured with Reference Date = End of Time.
