Importacular imports data connected to a constituent. The initial mapping with Importacular must be a constituent and all other data within the import will ultimately be linked to that constituent.
Depending upon what type of non-constituent data you would like to add to the Raiser's Edge, you may not be able to make changes with Importacular. Campaigns, Funds, Appeals, Attribute Categories and Events are examples of records that cannot be added or edited with Importacular (with the exception of being able to add Participants to the Event module).
However, many of the code tables located in Raiser's Edge under Configuration can be added to or fields may be changed from inactive to active during an import by selecting those options on the field settings throughout Importacular.
