Deleting a Decision Entity
You can delete a decision entity from your file system.
To delete a decision entity:

Delete from the context menu. Hold down SHIFT or CTRL to select multiple decision entities. 2. In the Delete Resources dialog box, do one of the following:
a. To delete the decision entity, click OK.
b. To open a list of all changes to be performed, click Preview. To confirm the changes, click OK.
