Hello there, Sastra.
We can save customized reports in the Classic mode by using the Save Customization button and assigning a unique name (e.g., Transaction Report - Classic View) for easy identification. Let me guide you through this process.
Here's how:
- Click the Reports menu and select Standard reports.
- Choose the report you want to make changes to, then select Customize report.

- After you've made the changes you want to the report, click Run report.
- In the Report name field, enter a descriptive name for the report.
- Switch on Share with others, to make it visible to others who can access the report.
- Select Add to group ▼ dropdown, then select the group you want to add this report to.
- Click Save.
