order of calculating values?

rbuser

Dear all,
I have 2 similar reports, both have 2 subreports. One subreport
looks at invoices the other at credits.

On the summary of the main report I have a ppvariable. I want it to show the
total of all invoices -all credits.

In the detail band of the subreports I have a beforegenerate event of
total:=total+qinvoiveamount.asfloat;

and

total:=total-qcreditamount.asfloat; respectively;

on the oncalc event for the ppvariable I have
value:=total;


In one report all works perfectly. On the other, the ppvariable value is
calculated BEFORE any traversing of the records.

I cannot see what is different in the way I have defined the 2 reports.
Where should I be looking?

many thanks

Place a TppVariable in the subreport. Use its OnCalc event to increment the
Variable in the main report:

procedure varSub.OnCalc(Sender: TObject; Value: Variant);
begin
varMain.Value := varMain.Value + plDetail['Amount'];
end;
