Question #: 26
Topic #: 3
You are configuring two report parameters. The second parameter must refresh its available values based on the value selected in the first parameter. Which two selections support this cascading parameter behavior?
A.
Select Refresh other parameters on change
B.
Set the parameter type to Date
C.
Use Fixed Data as the parameter type
D.
Select Multiple Selection as the LOV type for the dependent parameter
The technically correct combination is A and E . Oracle Analytics Publisher implements cascading parameters primarily through a Menu parameter backed by a List of Values , together with the Refresh other parameters on change option. Oracle states that Menu parameters support partial-page refresh for cascading parameters. When Refresh other parameters on change is enabled on the controlling parameter, Publisher performs a partial refresh of other parameters whose available values depend on the changed value.
For example, a Department Menu parameter can control an Employee Menu parameter. When Department changes, Publisher reevaluates the dependent employee LOV and presents only employees belonging to the selected department.
Multiple Selection does not create or enable cascading behavior. It merely allows more than one value to be chosen from a parameter's list. Therefore, option D in the uploaded source key should not be treated as the mechanism that establishes the dependency. A Date parameter does not provide the required LOV-based cascading model, while Fixed Data does not dynamically reevaluate dependent values.
Accordingly, this question requires a correction from the supplied key: Refresh other parameters on change + Menu parameter is the Oracle-documented implementation.
