Defining Time Intelligence Calculations using the Business Intelligence Wizard

The time intelligence enhancement is a cube enhancement that adds time calculations (or time views) to a selected hierarchy. This enhancement supports the following categories of calculations:

  • Period to date.

  • Period over period growth.

  • Moving averages.

  • Parallel period comparisons.

You apply time intelligence to cubes that have a time dimension. (A time dimension is a dimension whose Type property is set to Time). Additionally, the time attributes of that dimension must also have the appropriate setting (such as, Years or Months) for their Type property. The Type property of both the dimension and its attributes will be set correctly if you use the Dimension Wizard to create the time dimension.

To add time intelligence to a cube, you use the Business Intelligence Wizard, and select the Define time intelligence option on the Choose Enhancement page. This wizard then guides you through the steps of selecting a hierarchy to which you are adding time intelligence and specifying which members in the hierarchy will have time intelligence applied to them. On the last page of the wizard, you can see the changes that will be made to the Microsoft SQL Server Analysis Services database to add the selected time intelligence.

On the Choose Target Hierarchy and Calculations page, you select the time hierarchy to which the time enhancement applies. You can apply the time enhancement to only one time hierarchy every time that you run the Business Intelligence Wizard. If you want to apply the enhancement to more than one time hierarchy, you run the wizard again.

After you select a time hierarchy, in the Available time calculations list, you select the calculations that apply to the hierarchy. The calculations that are listed depend on the levels in the hierarchy, and on the Type property setting for the attribute for each level. For example, a Years hierarchy supports Year to Date and Year Over Year Growth, but a Quarters hierarchy does not.

NoteNote

The Timeintelligence.xml template file defines the time calculations that are listed in Available time calculations. If the listed calculations do not meet your needs, you can either change the existing calculations or add new calculations to the Timeintelligence.xml file.

TipTip

To view a description for a calculation, use the up and down arrows to highlight that calculation.

On the Define Scope of Calculations page, you specify the members to which the new time views apply. You can apply the new time views to one of the following objects:

  • Members of an account dimension   On the Define Scope of Calculations page, the Available measures list includes account dimensions. Account dimensions have their Type properties set to Accounts. If you have an accounts dimension but that dimension does not appear in the Available measures list, you can use the Business Intelligence Wizard to apply the account intelligence to that dimension. For more information, see Adding Account Intelligence to a Dimension.

  • Measures   Instead of specifying an account dimension, you can specify the measures to which the time views apply. In this case, select the views to which selected time calculations apply. For example, assets and liabilities are year-to-date data; therefore, you do not apply a Year-to-Date calculation to assets or liabilities measures.

On the final page of the Business Intelligence Wizard, you can view the changes that will be made to the Analysis Services database. For a time intelligence enhancement, the wizard will change the selected time dimension, associated data source view, and associated cube as described in the following table.

Object

Change

Time dimension

Adds an attribute for each calculation (or view).

Data source view

Adds a calculated column in the time table for each new attribute in the time dimension.

Cube

Adds a calculated member that defines the Multidimensional Expressions (MDX) code to perform the calculation.
