how to use the same parameters among report and 2 subs?

hi,
I have a report that has 2 subreports in it. the main report and one subreport run the same stored procedure and expect the same parameters and the second sub runs another stored procedure but expect THE SAME parameters. how can pass/share these parameter among the three reports without having to enter the parameters three times?

thank you

Pass the parameters of the Main report to the two subreports.

Right click on the subreport in the main report and select the Change Subreport Links menu.
