RI load of Discount Rates - how to remove previously errored records?

Summary:

We are loading the Discount Rate Index semi-regularly to Lease Accounting via the Rapid Implementation spreadsheet. If I load the RI and an error is generated, all subsequent loads with the error cause corrected still fail to load and report the same error. I can load the same file that fails in one environment successfully into a new environment. So, my question is, how can I purge the errored data for lease accounting rapid implementation so that I may correct errors and re-load data?

I.e. steps to reproduce:

1. Load Discount Rates via Rapid Implementation process to Lease Accounting - load intentionally with error, i.e. first rate effective date not equal to start date of index.
