Customize Project Level Custom Fields
At the project level, you can choose which of the global level custom fields to use in a particular project. Custom fields can be defined for Test Executions (up to 20 fields) and Test Steps (up to 5 fields).
Note
Disabling a custom field on the project level simply hides that field but does not delete the data. To delete a custom field along with the data, you need to delete this field on the global level as an administrator.
When viewing custom fields for test executions and test steps, use the Columns button to display the custom field in the corresponding tables.
