Defining a Schedule – Internal Scheduling Logic

The following logic is used by the IOA Scheduling facility to determine whether to order a rule on a specific day:

1. DAYS/DCAL parameters are checked independently and a first tentative scheduling decision is created.
2. WDAYS/WCAL parameters are checked independently and a second tentative scheduling decision is created.
3. A third scheduling decision is created based on the above two decisions and the AND/OR value linking them.

   If DAYS/DCAL are not specified, the third scheduling decision is identical to the second scheduling decision. If WDAYS/WCAL are not specified, this third scheduling decision is identical to the first scheduling decision.

4. If CONFCAL/SHIFT are specified, the third scheduling decision is adjusted according to the CONFCAL/SHIFT criteria.
5. The third scheduling decision (as adjusted, if necessary) becomes the final scheduling decision. The IOA Scheduling facility decides whether to schedule a rule based on this third scheduling decision.
