How the queries gets processed in data model of report

Question

In a report for e.g there are four queries in data model.
In the first query there is a group there we are calculating the value of a formula column c_currency.
In c_currency for set of values we are calculating :p_curr.
:p_curr is a global variable i.e user parameter.
So :p_curr is getting used in format trigger of next group in second query.
So the first query will execute for suppose 15 set of values.
So :p_curr wil not retain the values for all that 15 sets of values or it will each time overwrite the value?
or whether the first query will execute for first set of value pass to next query then execute for 2nd set.or will it execute all set and will pass :p_curr to next query?

Answer 1

This has nothing to do with the number of tables in your query. Search for the error message in the Reports help and you find this:
Cause:     You are attempting to default a layout that, if created using current settings, would be too large to fit within the defined height and width of a report page.
Action:     Go back to the Report Wizard and reduce the values of default settings (e.g., shorten some field widths). Alternatively, you can increase the size of a report page using the Report property palette. Then redefault your layout. Continue making adjustments as necessary.
