How get one column's value in dashboard of obiee?

Question

I have two reports, MAIN report and DETAIL report. I want to get one column's value as the filter of DETAIL report.
For example, the MAIN report is
Class AVG_Age MAX_Age MIN_Age
Class1 13 15 11
Class2 14 16 12
DETAIL report is
Name Class Old Describe
Name1 Class1 15 ...
Name2 Class2 16 ...
Through the Navigation to implement it, when I click the 15 of MAIN report, it can only show the MAX age student of calss1. So I have to put the MAX_Age as the DETAIL report's filter. How can I get it?
Thanks

Answer 1

If I understand correctly, what you are trying to do is build a report so that a user can determine the oldest student of a particular class and then look at the details of that student, yes? But what if several classes have a student (or students!) with the same "max" age? For example, what if there are students in 2 classes that are aged 15 and are the oldest in their respective class? Wouldn't you want to give the user the option if choosing the various classes in which the oldest student is the "max" age? Then do this:
On the Main report, put the summary information as you have it (Class, AVG_Age, MAX_Age, MIN_Age). Put the Value Interaction navigation on the MAX_Age column.
On the Detail report, put Class, Name, Age, Description, etc., and any other columns that show the details of the student(s) that are the oldest. Add the filter on the Age column: "Is prompted." Now, create a Pivot Table view and place the Class column in the Pages area. (If you want you can create a duplicate of the Class column so you can have a copy in the Rows section of the Pivot Table.)
Now when the user clicks on the MAX_Age in the Main report, it will show the Detail report with the Classes that have students with the same "max" age in a drop down window. The user can select different classes to see the various students that meet that criterion.
