The Jobs tab was renamed to Reports and Jobs as part of an enhancement included starting in CA PPM 15.3, as you are now able to run or schedule reports directly from the Reports in Classic PPM.
See an excerpt from the 15.3 Change, Impact and Upgrade guide documentation below:
Advanced Reporting Changes for Release 15.3
Run or Schedule Jaspersoft Reports Directly Inside Classic PPM
You can run, schedule, share, check status, and view Jaspersoft Studio reports inside CA PPM SaaS. The Home menu includes the Reports and Jobs menu option. The resulting intuitive two-tab page provides a convenient place for users to schedule reports and jobs. With pre-configured access from administrators, users can now save their own report parameters.
In previous releases, users scheduled reports that were potentially visible to other users in common Jaspersoft folders. This release provides an enhanced, more secure reporting experience. Users can also save their own report parameters without edit permissions for the Jaspersoft report. Users can view only their own scheduled reports or the reports shared by other users.
Upgrade Action: After the upgrade, review the reports and jobs that your organization wants to make available to your users. Configure notification messages to alert users about scheduled and completed reports. Assist users with scheduling and sharing reports. Refresh the data warehouse with recurring jobs. Grant access rights and help them receive notifications. See Run, Schedule, and Share Reports. See also Jobs and Access Rights in the Reference section and the descriptions of each report in the Advanced Reporting section of the English edition of the documentation.
