You need to set up a license acquisition contract with the following:
One IP
Two royalties items with different royalties rates
One tiering group that contains the two royalties items
In this example, a change occurs in the scale rate, effective as of a certain date. This is reflected in the contract by the two royalties items with different royalties rates.
