MonthsEnd(n_months, date[, period_no [, first_month_of_year]])

Return data type: dual


MonthsEnd arguments
Argument Description
n_months The number of months that defines the period. An integer or expression that resolves to an integer that must be one of: 1 (equivalent to the inmonth() function), 2 (bi-month), 3 (equivalent to the inquarter() function), 4 (four-month period), or 6 (half year).
date The date to evaluate.
period_no The period can be offset by period_no, an integer, or expression resolving to an integer, where the value 0 indicates the period that contains base_date. Negative values in period_no indicate preceding periods and positive values indicate succeeding periods.

If you want to work with (fiscal) years not starting in January, indicate a value between 2 and 12 in first_month_of_year.

Examples and results:  

These examples use the date format DD/MM/YYYY. The date format is specified in the SET DateFormat statement at the top of your load script. Change the format in the examples to suit your requirements.

Example 1:  

monthsend(4, '19/07/2013')

Example 2:  

monthsend(4, '19/10/2013', -1)

Returns 31/08/2013.

Example 3:
