In the article register, you'll find a list of every article registered in Engage. This comes in handy if, for example, you want to know what you can build segments on or if you're looking for information about articles that award bonus points.
Click on Administration in the left-hand menu and choose Article list to open the register.
In the upper left corner of the table, you can search for a SKU, product category, brand or whatever you want to find. In the upper right corner of the table, you can sort the list by the available attributes, either in ascending or descending order.
