You must first add products to cart to use Deal Guidance. When you update a field of a line item that is a parameter for the deal rating and reprice the cart, a colored shape is displayed in the Guidance field. For example, if you apply an adjustment on the line item by providing a discount of 25%.

A colored shape () is displayed in the Guidance field according to the defined rule in the below image, indicating that the deal is below average.  You can open the Pricing Guidance pop-up, like the one below by clicking the colored shape that is displayed in t26pxhe Guidance field. The pop-up lists the range in which you can apply discounts and how the deal is rated. You can update the fields with a value that brings the deal under a more desirable range using the rule pop-up.

For the Deal Guidance measure Custom, the pop-up displays blank values/blank cells for the Unit Price From and Unit Price To.

The following image displays the unit price measures. 

 

You can finalize the cart even though the deal is not appropriate unless there are other approvals required.
