August 8, 2005

Procedure

Create a New Aging Shared Dimension

We will create support for aging within our cube by adding a new shared dimension. It will be within this dimension that we construct the logic to derive our aging buckets.

1.  Right-click the Shared Dimensions folder within the new AgingDim Analysis Services database.

2.  Select New Dimension from the context menu that appears.

3.  Select Editor from the cascading menu that appears next, as depicted in Illustration 12.

4.  Scroll down in the Tables pane (left half of the dialog), to locate the time_by_day table in the clone database.

5.  Select the time_by_day table, as shown in Illustration 13.

6.  Click OK to accept the selection, and to progress to the Dimension Editor.

7.  From the Schema tab in the Dimension Editor, drag the field named the_date from within the time_by_day table to the left, dropping it onto the <New> dimension in the tree, as depicted in Illustration 14.

Our changes appear as shown in a partial view of the Dimension Editor in Illustration 15.
