Execute queries in parallel

[Bindiya]

Hi all,
We have two crosstabs in report which are pointing to same query. I have set Execution Method=Concurrent for this query. Now, since we have 2 crosstabs, Cognos generates two report queries for each data container (crosstab). So will these two queries get executed in parallel? or will the concurrency work only if those crosstabs were tied to two different queries (with concurrency set for both of them).

What should be done to make all the report queries generated for each data containers (that were using same query) to execute in parallel?

Please help..
