A risk register is a collection of risks and is attached to a single project. In order to use the application correctly, you need to have the appropriate fields, issue type, and workflows set up for the project. See /wiki/spaces/DOC/pages/568688654for more details.
The application provides a screen to enable you to check whether everything is configured correctly for a project or not. Follow these steps:
Select the gear-shaped icon in the top right hand corner of the screen and then select Manage Apps. The Risk Register application menu appears in the left-hand navigation pane; select Risk registers.
A page displaying all of the risk registers in your server instance appears. Click on the one that interests you and select the Settings item.
