When importing Pledges or Recurring Gifts into the Raiser's Edge using Importacular, the Schedule Wizard can help create default values within your template for the schedule.
If your data source contains multiple options for scheduling (for example if donors can select which day of the month on which their gift is processed), then you will need to fill in the template with Source Field data rather than simply relying on the Schedule Wizard.
You can read more about the Schedule Wizard and scheduling on this page of our User Guide or you can watch a video demonstration of how these schedules can be imported here.
For more information regarding the fields used to import schedules, please refer to Blackbaud's Knowledgebase (this article in particular may be of help).
