Set Up Lunar Time Periods - IBM Cognos User Manual

Example - Changing How Partial Weeks are Handled at the End
of the Year
In this example, you change how partial weeks are handled at the end of the
calendar year.
Because your business aligns its fiscal year with the calendar year, you do not
want Cognos Transformer to apply the default setting Always Split when
reporting the data for partial weeks at the end of the calendar year.
Procedure
In the Partial weeks box, you select the First Period setting. This places the
spanning week into the year in which that week begins, so that the data for that
week is accorded to December, the last month in the first fiscal year.
Results
The days in the partial week are associated with the December 2006 time period,
as follows:

Set up Lunar Time Periods

Many businesses track performance according to the lunar calendar: that is, a year
has 52 weeks, with seven days in each week, yielding 364 days.
Lunar time dimensions may contain lunar years, lunar quarters, lunar months, and
other reporting periods such as 4-4-5 week months, 4-5-4 week months, and 5-4-4
week months.
Whereas lunar quarters or months must be placed in a lunar time hierarchy, you
can add weeks and day levels to your hierarchy, as children of either lunar or
standard calendar time periods.
To display the ending year (rather than the starting year) as the label for a lunar
fiscal year that spans two calendar years, select the Enable lunar fiscal labelling
option on the General tab of the Preferences property sheet on the File menu.
On the Categories diagram, the default label for each lunar month uses the format
YYYYMM. The lunar months are numbered in sequence, beginning each year with the
value 01, as specified in the Year begins property.
Lunar weeks and lunar days are labelled inYYYYMMDD format, where DD is the first
day of the week on the standard calendar.
You can use the Date Wizard to create lunar time dimensions, and choose your
required lunar time periods when prompted.
Because lunar years comprise 52 weeks and not 365 days you must ensure that the
Year begins and Week begins on properties coincide. You have two options:
v You can reset the Week begins on property for each year.
v You can accumulate the remainder days in a new category using the Add an
