Specify How Weeks Split When Spanning a Higher-level Time
Period
In a time dimension that includes weeks, you can choose from three options to
handle weeks that span a higher-level time period.
To specify how weeks split, choose from the following options:
v Always split the spanning week into two separate weeks, each of which includes
the days that occur in the higher-level time period.
Each part of the split week appears in the Categories diagram as a separate
week. For example, the week beginning Sunday, December 31, 2006 and ending
Saturday, January 6, 2007 appears as two weeks: 20061231 (a child of December)
and 20070101 (a child of January). Always Split is the default setting.
v Split the spanning week into two distinct weeks, but not if a 1-day week is
created as a result. Select the Split > 1 day setting.
For example, Sunday, December 31, 2006 appears in the same week as 20070101.
v Place the spanning week in a specific time period: First Period, Last Period, or
Largest Period.
Procedure

2. Open the Drill Category property sheet.
If the dimension contains multiple drill-down paths, open the Drill Category
property sheet for the drill-down path you want to change.
3. Click the Time tab.
4. From the Partial weeks box, select the week-spanning rule to apply and click
OK.
