You should be able to create a report to execute from Classic UI. To do that setup a report in Administration->Data Administration->Reports and Jobs->Click New
1. Fill in all required details like Job Name, ID, Description, Executable Type = Report
2. Executable Name should be like: /ca_ppm/ad_hoc_views/ad_hoc_reports/REPORT_NAME (You can get these details from Report properties in Advanced Reporting)
3. Activate Parameters and follow further steps.
By following above steps you should be able to see the new report in Reports and Jobs and should be able to schedule the report.
