Display running sum amount brought forward from the previous page

rbuser

Hi,
Can any one tell me how to display the sum amount from previous pages
in the page header?

Thanks

Hi Vincent,

Try placing a TppVariable inside the footer band of the report set to
calculate on traversal and another TppVariable inside the header band.
Inside the first variable's OnCalc event, calculate the running total and
assign its value to the variable in the header. Take a look at the
following example I created that does this.

Hi, Nico,
I use the same method in my report but the header variable always
sum the first data amount in every page( even in the first page).
Is there any other setting I have to take care

ps. I am using Report builder 10.02 in delphi 2006

Hi Vincent,

Please send all attachments to support@digital-metaphors.com.

Due to the timing in which variables are calculated, it seems the next
record is being added to the value of the variable. You can try to subtract
this value from the header variable's value.

Value := Value + ppReport1.DataPipeline['AmountPaid'];
ppVariable1.Value := Value - ppReport1.DataPipeline['AmountPaid'];
