Although you can define multiple bursting definitions for a single data model, you can enable only one for a report.
Enable a report to use a bursting definition on the Report Properties dialog of the report editor. See Configuring Report Properties in Report Designer's Guide for Oracle Business Intelligence Publisher.
After you configure the report to use the bursting definition, when you schedule a job for this report you can choose to use the bursting definition to format and deliver the report. See Creating a Bursting Job in User's Guide for Oracle Business Intelligence Publisher.
You can also opt not to use the bursting definition and choose your own output and destination as a regular scheduled report.
