I am using report builder and i have to register this report in oracle apps.
Here would be your work around:
1. Create a report using reports builder that display student information by taking student ID and student email address as input parameter
2. Design the layout as you want to display the information
3. Once the report is run, in the after report trigger , write a pl/sql code that will send email of the output of the report to a email address that is passed as input parameter in step 1.
4. make use of
UTL_SMTP for implementing mail functionality
let us know in case of any issues!!
