Deleting a business issue or a group
Remove a business issue or group that you no longer need in the propositions hierarchy. This action does not result in deleting the class that represents the business issue or group. It removes a given issue or a group from the proposition hierarchy context by changing the
pyDecisioningItem custom field of the class from the Issue (for issue level classes) or Group (for the group level classes) to MarkedForDeletion.
In the header of Dev Studio, click.
In the Business issues and groups section, click the Trash icon to remove an entry.
