You can update the layout of an existing report by replacing the report with an external report file. For example, you can use this method to import your changes into Alloy Discovery reports.
NOTE: You may want to save your current report to an external file for backup purposes before replacing the layout. For details, see Saving report layouts to external report files.
To replace a report with an external report file:
On the main menu, click Reports > Reports and open a desired report category from the Categories pane
In the Reports grid, right-click the report you want to replace and choose Replace from the pop-up menu.
Select the source report file and click Open.
