To delete an entity, you must have the Entity-View and Entity-Delete permissions. You can either delete one entity at a time, or all entities in a group.
To select which entities to delete:
Go to Entities > Entities and select an entity group.
Select the checkbox next to each entity you wish to delete.
Click Delete, then OK.
If there are any linked objects on one or more of the selected entities, they will be listed in the pop-up window asking you to confirm.
To delete all entities in an entity group:
Go to Entities > Entities and select an entity group.
Select Delete All from the More Actions dropdown list.
Click OK.
The pop-up window asking you to confirm will display the name of the group the entities are a part of.
