Logical Levels in OBIEE

1 . Use a different technique to associate logical columns with logical levels. Drag the logical columns from the Time Detail logical level (not from the D1 Time logical table) to their corresponding levels in the H1 Time logical dimension. This is a convenient technique when logical columns are buried deep in the business model.

Logical Column Logical Level
Per Name YearYear
Per Name HalfHalf
Per Name QtrQuarter
Per Name MonthMonth
Per Name WeekWeek

Your results should look similar to the screenshot:


2 . Delete all remaining columns from the Time Detail level except for Calendar Date so that only Calendar Date is associated with the Time Detail level. Notice that deleting objects from the hierarchy does not delete them from the logical table in the business model.

 Create a Logical Dimension for Customer

1 . Use either technique to create a logical dimension with a level-based hierarchy named H3 Customer for the D3 Customer logical table with the following levels, columns, and keys. Hint: Create the levels first, then double-click a logical column to open the Logical Column dialog box and use the Levels tab to associate the logical column with a logical level.
