Linked value attributes (LVAs) are a type of attribute used to describe the periodicity of Time dimension members. Periodicity is any shared pattern among time dimension members that makes them meaningful for time-based analysis. For example, January and April share the periodicity of being opening months of a quarter in the Gregorian calendar.
Use this dialog box to define LVAs for those periodically recurring members that you want to aggregate for analysis. You can aggregate on parameters such as quarter by year, month by year, or week by quarter.
