Passing values from the Main Report to the Sub report

[QueTech]

Hi,

I am pulling data from a cashe database on Win PX workstation. I am using Crystal 10. My question is can I pass variable values from my main report to my subreport?

Sure. they're called shared variables.

Example:

In a section PRIOR to running the subreport:

whileprintingrecords;
shared numbervar MyValue:= sum({table.field})

Then in the subreport you can reference it:

whileprintingrecords;
shared numbervar MyValue;
"I have " & totext(MyValue,0,"") & " from the main report"

and you can pass values back.

For main-to-subreport, it is easier to use Edit > Subreport Links. Just be aware that it will want to link to something in the subreport, and that this link will be automatically placed in the subreport's record selection. If it's not what you want, it can be edited out.
