Using negative run cycles

A normal run cycle specifies the day on which an application occurrence should be generated, relative to the dates of a period. Suppose you have an application INVENTORY, which runs on the first day of each month. You might not want INVENTORY to run every calendar month, for example, because an inventory is not taken in December. You can specify this by creating a negative run cycle for the application INVENTORY. A negative run cycle specifies the days that you do not want an application to run, even though the application normal run cycle has specified these days as run days.

Negative run cycles are types E and X, as opposed to normal run cycles, which are types R and N. When the long-term planning process finds a run cycle of type E or X, it generates a negative occurrence. To stop an occurrence generated by a run cycle of type R or N, the input arrival times on the normal and negative run cycles must be identical.
