You can enable support for functions and access to Functions Builder by customizing the manifest file.
Enabling Support for Functions
To give users the ability to use the supported Oracle Smart View for Office (Mac and Browser) functions, select the Include Functions support check box.
With this check box enabled, and the Build Function menu option disabled, users may manually add or edit supported functions on a worksheet.
Selecting the Include Functions support option does not automatically select the Build Function menu item.
However, the Include Functions support option is automatically selected when you select the Build Function option in the next step.
Enabling Access to Functions Builder
To enable access to the Function Builder interface, select the Build Function menu item in the General group.
The Build Function menu item is not selected by default.
When the Build Function option is selected, the Include Function support check box is automatically selected.
If you have already selected the Build Function option, and then change the business process, be sure to verify that your selections in the General category are correct, and that the Include Functions support check box is selected.
