Noncyclic periods

Examples of noncyclic periods are a quarter, and a payroll period. You specify the start of each interval of a noncyclic period with an origin date.

This example shows a period for university semesters, with the interval origin and end specified for each semester:

Noncyclic period

 PERIOD NAME  = Semester
 PERIOD TYPE  = N
 INTERVAL ORIGIN   INTERVAL END
 26 August   2002  13 December 2002
 13 January  2003  16 May      2003
  9 June     2003  28 June     2003

Noncyclic periods have a once-a-year maintenance overhead when you must create the intervals for the coming months. For this reason, carefully consider how flexible your period definitions are, and remove potentially duplicate definitions.
