Calculates the values up to the previous period within an ancestor or within a level.
The template presents an ancestor or a level for a measure of the analytic view, an attribute dimension the analytic view is dimensioned by, a hierarchy that uses the attribute dimension, an aggregation operator, and the beginning or end of the period. To select a different value for an option, click the underlined value in the template and make a selection from the Select Measures dialog box or the drop-down list or enter a different number value.
Template
{ Level | parent | ancestor at level level name } to date number period ago for the measure name measure for the attribute dimension alias attribute dimension and the hierarchy alias hierarchy. Aggregate using { SUM | MAXIMUM | MINIMUM |AVERAGE } from the { beginning | end } of the period.
Example: Example of Period To Date Period Ago
The sales_to_date_yr_ago calculated measure calculates a running total of the SALES measure values for the hierarchy members that have the same ancestor at the year level from the beginning of the period to the current member.
Calculation in Template
Ancestor at level YEAR to date 1 period ago for the SALES measure in the TIME_ATTR_DIM attribute dimension and TIME.HIER hierarchy. Aggregate using SUM from the beginning of the period.
Definition of Calculated Measure in Analytic View
The MEASURES clause of the SALES_AV analytic view definition includes this definition of the sales_to_date_yr_ago calculated measure:
sales_to_date_yr_ago AS
LAG (
SUM(SALES)
OVER (HIERARCHY TIME_ATTR_DIM.TIME_HIER
BETWEEN UNBOUNDED PRECEDING AND CURRENT MEMBER
WITHIN ANCESTOR AT LEVEL YEAR))
OVER (HIERARCHY TIME_ATTR_DIM.TIME_HIER OFFSET 1)
SELECT Statement Using the Calculated Measure
Query the analytic view, selecting sales and sales_to_date_yr_ago values.
SELECT time_hier.member_name as TIME,
sales,
sales_to_date_yr_ago
FROM
sales_av HIERARCHIES(time_hier)
WHERE time_hier.level_name IN ('YEAR', 'QUARTER')
ORDER BY time_hier.hier_order;
