You can delete a custom defined template from the System View. Before you delete a custom defined template, make sure it is not being used in any business rules or any custom folders. To see if a custom defined template is being used by any business rules or custom folders, you can show its usages from the System View. See Showing the Usages of a Custom Defined Template (Financial Management, Planning, and Essbase Block Storage Application Users Only). If the template is being used by business rules, you must remove it from them before you can delete it. See Removing a Custom Defined Template from a Business Rule's Flow Chart (Financial Management, Planning, and Essbase Block Storage Application Users Only).
