Returns the percent difference between the measure value of the current member and the measure value of a previous member at the same level.
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, and a number that specifies the offset from the current member. To select a different measure, attribute dimension, hierarchy, or number, 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
Percent difference from prior period for the measure name measure for the attribute dimension alias attribute dimension and the hierarchy alias hierarchy number period ago.
Example: Example of Percent Difference from Prior Period
The sales_pct_chg_prev_yr calculates the percentage of the difference between the measure value for the current member and the measure value for the hierarchy member that is one member before the current member at the same level.
Calculation in Template
Percent difference from prior period for SALES in TIME_ATTR_DIM and TIME_HIER hierarchy 1 period ago.
Definition of Calculated Measure in Analytic View
The SALES_AV analytic view definition MEASURES clause includes this definition of the sales_pct_chg_prev_yr calculated measure:
sales_pct_chg_prev_yr AS
(LAG_DIFF_PERCENT(SALES) OVER (HIERARCHY time_hier OFFSET 1)
SELECT Statement Using the Calculated Measure
Query the analytic view, selecting hierarchy members, sales values, and the percent of sales for a year compared to the previous year.
-- Select the SALES and SALES_PCT_CHG_PREV_YR measures at the YEAR level.
SELECT time_hier.member_name as TIME,
sales,
ROUND(sales_pct_chg_prev_yr, 4) AS sales_pct_chg_prev_yr
FROM
sales_av HIERARCHIES(time_hier)
WHERE time_hier.level_name IN ('YEAR')
ORDER BY time_hier.hier_order;
