Measure dipaly based on Second Highest Max Date

Hi,

I have a requirement in webi report to dispaly records as  sales Revenue for Max. Date  and  sales Revenue for second Highest Max Date

Report As below:

Product Id, Product Name ,Agent  Id, Agent Name,  Max_Date, New_Sale Revenue, Old_Date, Old_Sale Revenue

For Maximum sales Revenue I used Max. function in Universe and in the report with separate DP for Max Date
generating with Max. Date Sales Revenue as expected.

=(Sales_Revenue) where DP1.Date= DP2.Date.It works as expected when i used separate data provider DP2 for Max Date.But i need to display at the same time second Highest Max Date sales revenue in  Old_Date, Old_Sale Revenue columns in report structure.

Please suggest how can i generate in the same report Old_Date and Old_Sale Revenue as (Sales revenue for second Highest Max Date).

Thanks in
Advance.
