Tags in the Above Store Console allow you to more easily filter tasks, library files, and more. You must first create tags to use throughout the ASC, and then assign those tags where needed.
You must first create tags, and associate them with specific stores before proceeding. You can learn how to do that HERE.
Throughout the ASC you are able to filter stores using the tags you create. Simply define the needed locations using rule drop-down menus and check boxes.
For example, if you’d like to have a file in your library accessible to only certain stores associated with the Table Service Only tag, you can define the rule as “That have” and “Any”, and then check that tag’s box on the right under the Stores sub-tab. Only the stores associated with that tag will show on the left, and you can more easily check only those that are appropriate. Save when finished.
