Universal Containers wants to add a rebate benefit defined by a product dimension.

Benefit mappings are used to define the product dimensions for a rebate benefit. Product dimensions are the criteria that determine which products are eligible for a rebate benefit. For example, you can create a product dimension based on product family, product line, or product category. You can also create custom product dimensions to suit your business needs1. To create a product dimension for a rebate benefit, you need to add a benefit mapping related list to the benefit record and specify the dimension type and values2. References: 1: Define Product Dimensions for Rebate Benefits | Salesforce Help3, 2: Create Benefits and Activate a Program Unit | Salesforce Trailhead4
