You can use the Function Editor to insert Essbase functions into your business rules, sequences, variables, and macros. See the Essbase Technical Reference.
To insert a function with the Function Editor:
If it is not open, open the business rule or macro into which you want to insert a function.
In the lower left area of the Administration Services Administration Console, select the BR Language tab.
Under the Language folder, expand the Functions Alphabetically or Functions by Category folder.
A list of the functions you can use to help you design your business rule, business rule sequence, macro, or variable is displayed. See the Hyperion Essbase Technical Reference.
To insert a function, drag and drop the function onto the Source tab.
The Function Editor is displayed. It contains the name of the function, its description, and whether it is required. It also contains arguments whose values you must enter.
In the Value text box, enter values for all of the required arguments that are listed.
Click OK.
