When you copy functions, you associate them with one application or all applications on the target server. You can copy functions within an Essbase Server instance or application or between Essbase Server instances and applications (provided that you have appropriate access privileges).
List boxes of the Copy Function dialog box:
Essbase Server—Select the Essbase Server instance to which to copy the function.
Application—Select the application to which to copy the function, or select <all apps> to copy the function to all applications on the selected Essbase Server instance.
Functions—Select the function or functions to be copied.
If you want the copied functions to replace functions of the same name, select the “Overwrite existing functions” option.
