Calculate variable in one subreport and use it in another

rbuser

Hi,

I am struggling with the following:

Mainreport has a child subreport placed in the detail band. This subreports
calculates a value i have to use in a second subreport placed in the
summaryband of the main report.
I have used a global TppVariable in the past to show a subreport value in
the main report but I can't use this technic to share a variable between 2
subreports i think.
How should I get this working?

Using D7, RB 7.04 Ent.

Hi Jeroen,

You should be able to access the global variables from the second subreport.
The same concept applies as showing a variable value in the main report.
You will need to assign the global variable value inside the OnCalc of the
variable in the first subreport, then assing the global variable to a
variable located in the second subreport.

Hi Nico,

I can't get it to work (result stays 0.00). when using a variable in the
mainreport.summary works ok.
The variable in the second subreport has 'calculate on' reportend and 'reset
on' reportend like in your example 'TotalsFromSubreportWithRAP.zip'.

Hi Jeroen,

Are you simply trying to display the calculated value of a variable located
in the first subreport inside the second subreport? If so, you can simply
place a TppVariable inside the second subreport and assign it's value to the
already calculated global variable, perhaps in the Band.BeforePrint event.
Something like the following...

procedure DetailBeforePrint
begin
Variable1.Value := gSummaryTotal.Value

end;
