ad hoc webi reporting in BOXI 3.1?

Hi

actually in one universe i have to use 2 independent tables along with the regular tables.

Tables:

1) current data table

2) historical data table

So user requirement is -

When user tries to query for current data then it should refer 1) current data table for the condition

When user tries to query for Historical data then it should refer 1) historical data table for the condition

and generate the report data for the user.

Even i am confused with this requirement. Never experienced.

Thanks,

Bhaskar
