You may eliminate non-eighth rates by using the Rate/Price Selection Strategy Eliminate Non-Eighth Rates. If you are using this strategy in combination with the Dynamic Markup – Create an Exact par, an issue can occur where the exact par is created on one of the non-eighth rates. Then, the Rate/Price Selection strategy for Eliminate Non-Eighth Rates would fire deleting the par rate from the rate stack offering. Since we cannot change the order in which Dynamic Markups and Rate/Price Selection fire, this solution can solve for the issue: use the Dynamic Markup “Markup your pricing based on the adjusted Rate, Price, Lock and /or Margin”.
As you can see in the screenshot below, use the “Rate” option, and build out a grid to price out the non-eighth rates so they do not appear. Then, place this Eliminate Non-Eighth Rates in Strategy 1 and Create Exact Par in Strategy 2 in the Dynamic Markups Product Category Assignments, and turn off the Eliminate Non-Eighth Rates Rate/Price Selection strategy. (If you do not have the ability to apply multiple strategies, please contact your Client Services representative to have the functionality enabled.)
