I have two data providers with common dimension and
measures. The only difference between two data providers is
in condition 'Fiscal Year'.One data provider calculates for
current year and other one calculates for previous year. So
in prompts if I am passing 2008 as current year then the two
data providers should be able to calculate for current year
and previous year individually.
So Can anybody tell me how to do calculation in data providers.
( I am using BO WebI report )
