Calculates the difference between the current value and a prior parallel period.
The template presents a measure of the analytic view, an attribute dimension the analytic view is dimensioned by, a hierarchy that uses the attribute dimension, a position, a number that specifies the offset from the current member, a level, and a position. To select a different value, 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
Difference between the measure name measure for the attribute dimension alias attribute dimension and the hierarchy alias hierarchy and the { parallel period | parallel period closest } number level name ago based on the position from the { beginning to end | end to beginning } of the period.
Example: Example of Difference from Parallel Period
The sales_diff_parallel_period calculated measure calculates the difference in values between the current period and the parallel period one year ago.
Calculation in Template
Difference between the SALES measure for the TIME_ATTR_DIM attribute dimension and the TIME_HIER hierarchy and the parallel period 1 YEAR ago based on the position from the beginning to end 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_diff_parallel_period calculated measure:
sales_diff_parallel_period AS
LAG_DIFF (SALES)
OVER (HIERARCHY TIME_ATTR_DIM.TIME_HIER OFFSET 1 ACROSS ANCESTOR AT LEVEL YEAR
POSITION FROM BEGINNING)
SELECT Statement Using the Calculated Measure
Query the analytic view, selecting sales and sales_diff_parallel_period values.
SELECT time_hier.member_name as TIME,
sales,
sales_diff_parallel_period
FROM
sales_av HIERARCHIES(time_hier)
WHERE time_hier.level_name IN ('YEAR')
ORDER BY time_hier.hier_order;
