Edit Product – Product Grouping Section

Click the Actions button and select Edit Product
Under the Product Settings tab, scroll down to the Product Grouping Settings

Overview

The Product Grouping section lets you assign organizational attributes to products:

Product Groups provide a one-to-one relationship — a product can only belong to one group
Product Tags provide a many-to-many relationship — a product can have many tags, and the same tag can apply to many products

You need to define product groups first using the Product Groups settings screen. See How Do I Define, Assign, and View Product Groups
Settlement Periods can show financials consolidated by Product Groups
Filters on product screens can filter on any Product Tag
You can only assign one Product Group to a product
You can assign many Product Tags to the same product
Product Groups are saved on the parent account, so their names are visible to all guest users
Guest users cannot see data for product groups belonging to marketplaces/accounts not assigned to them

Click on the Product Group field to show a dropdown list of all groups defined through the Product Groups Settings screen.

Select the group to assign to this product
Once assigned, the product participates in the financials for that product group, as shown in the Settlement Periods screen
If the desired group is not on the list, you need to define it first
