The Vintage Type, Vintage Percent and Royalty Payor Interest columns are used in calculations for the BC09 Oil Estimate. These fields should be populated automatically when new rows are added by the BC09 Invoice import. However, these rows are editable for users to update or override.

The two buttons to the top-right of the screen, "Update Payor Interest / Vintage Percent" and "Update WA Num" can be used update their respective rows with detail from the most recent invoice.
