After you drag-and-drop an object into the workflow, you can not drag it back off the canvas. Instead, to remove the object from the workflow, you must delete it from the workflow. This also deletes any rule you had associated with the object. If you decide to drag the same object back onto the workflow after deleting it, you need to create the rule again before saving the workflow.
To delete an object from the canvas:
1. Within the designer, perform one of the following actions to the object:
· select and press Delete
· right-click and select Delete Rule
