An SDD is a Scheduled Data Delivery. To add an SDD to Rapid Response, Prospectus Request or Mobile Event Capture, you must be a superuser. SDDs are configurable to deliver data on a daily, weekly or monthly basis. The day of the week and time of day are also specifiable. The data is delivered by email as a link to a CSV. For extra security, the file can be zipped and password protected.
An SDD can also create a PDF sheet of labels so that the team can print a sheet of labels, eg for a postcard campaign.
If you need to check whether a student has gone onto a SDD, you can do so by looking at the logs on their record card in Student Database:
