Hi,
I need to develop a report the data for which cannot be easily selected from tables using a sql statement. It needs to first call a stored procedure which would populate some temp tables and crystal would then report from these temp tables.I am from Oracle reports background which has a before report trigger in which you could put any of this pre-processing but not sure if crystal (CR XI) has the equivalent of that.what I did try with crystal was this :- 1. On my main report I have this query - select * from temp......2.I have put a sub-report in my Report Header section. This sub-report calls a sql server stored procedure which populates the temp table.But what I am finding is that before the sub-report is called crystal has already executed the select statement -which is still empty at this stage.Question:1.What I am trying to do is just not possible to do in crystal ?2. Or is there a way that I can stop crystal from executing the main select statement until the sub-report has been called ?thanks in advanceVishal

Why not just use a single Command object as your datasource, and have it contain the following sql:
exec sp_your_stored_procedure
--that should have generated your temp_table
select * from your_temp_table
drop table your_temp_table --or not, depending on your preference...
