Selecting "Current" designates that this will be the active Price Rollup formula for the Product Line or Price Group. You can still choose to set its Effective Date in the future. It will override any currently entered price rollup schedule for the products.

Selecting "Future" allows you to enter a Price Rollup formula that will become effective on a future date without deleting your current Price Rollup formula. The future formula that you enter will become effective on the date that you specify, replacing the current formula.
