Member attributes
Member attributes help to explain or describe a member in a dimension.
For example, suppose that you have a dimension that lists cars. You could have attributes that describe fuel type, engine size or type, and number of doors.
You can show attributes in a table and you can select which attributes you want to show. You can sort on attributes, and you can convert attributes into a hierarchy. Converting attributes into hierarchies is useful if you want to group dimension members by attribute. For example, suppose that you want to display cars that have a gasoline engine, you can add an attribute called Engine type, then create a hierarchy from the Engine type attribute. You would then be able to group members by Engine type attribute in the view.
You add member attributes in the dimension editor.
