Box 1: discount
Requirements. Pricing
Trey Research plans to do promotional pricing. Certain products will receive special pricing during the hours of extreme sporting events that Trey Research sponsors. Before or after the event, normal pricing will resume.
Box 2: periodic
A discount period defines the period during which a price adjustment or discount is valid.
Box 3: catalog
A product catalog is a collection of products with their pricing information. The product catalog entities let you create a rich product classification system in Dynamics 365 for Customer Engagement that provides support for:
* Defining multiple pricing and discounting models. You can also use custom pricing instead of the Customer Engagement system pricing to calculate prices when you associate a product or bundle to an opportunity, quote, order, or invoice. Further, you can select whether to apply discounts for products at the per-unit or line level.
* Etc.
Note: Price groups are at the heart of price and discount management in Commerce. Price groups are used to assign prices and discounts to Commerce entities (that is, channels, catalogs, affiliations, and loyalty programs). Because price groups are used for all pricing and discounts, it's very important that you plan how you will use them before you start.
* trade agreement discounts
The capability to work with categories is a key differentiator between discounts and trade agreement discounts, and the main reason that we discourage you from using trade agreement discounts. Categories are organized in a multi-level hierarchy. By contrast, the item discount groups that are used by trade agreements are only a single level of grouping, and each group is specific to one of the three trade agreement discount types, such as Line discount, Multiline discount, and Total discount. Therefore, for trade agreements, if you want to use the same set of products in all three trade agreement discount types, you must create and manage three independent discount groups.
* An affiliation identifies customers who are members of a group, or are associated with one, for example, seniors or students. Before you can add affiliations to customer records, you must set up affiliations and their discounts.
