Change the definition used for reporting Upsold and Downgraded customers and revenue to exclude changes below a specified amount, either by value or percent as per the instructions below.

To change definitions to include a full month view, see How to show a full month view of revenue (as used for MRR). 

First, select the report for which you want to change the definition.

Go to the button at the top left of the screen, with three dots and select "Change Definitions" from the resulting drop down menu.

Then select either value or % in the Definitions box drop down menu and type in your selected amount.

Save your changes. The new values will be applied to the report selected.

Repeat for other reports, if required.
