Multiple Procedure Schedules and Intervals

Multiple procedure schedules are defined to run different procedures at different intervals, for example, monthly, quarterly and annually. The schedule must be defined so that all procedures are run at intervals that are even multiples of the recurrence specified on the Schedule page.

For this type of schedule, the recurrence for the most frequent procedure is defined on the Schedule page. The other procedures are then defined on the Procedures page. For example, the monthly (base) procedure would have an interval of 1, the quarterly procedure an interval of 3 (at the third month), and the annual procedure would have an interval of 12 (at the twelfth month).

Since a single procedure is run at each interval, the content of the procedures should be cumulative. That is, the Quarterly procedure should include all monthly tasks, plus the additional quarterly tasks; the Annual procedure should contain all the quarterly tasks, plus the annual tasks. To simplify this process you can clone a procedure and then add the incremental tasks.

The following tables summarize common interval settings for multiple procedure schedules:

Base Schedule (Monthly)	Interval
1	Monthly
3	Quarterly
12	Annual

Base Schedule (Weekly)	Interval
1	Weekly
4	Monthly
12	Quarterly
48	Annual

Base Schedule (Bi-Weekly)	Interval
1	Bi-Weekly
2	Monthly
6	Quarterly
24	Annual

Base Schedule (Every 3 Months)	Interval
1	Every 3 Months
4	Annual
