Creating sum of calc fields

rbuser

Hi,

If I have a variable used for a calculation in a detail line, what is the
preferred way to total the sum of detail lines at group level?

Thanks

Alex

If you have a TppVariable calculation, then use another TppVariable to
calculate the total of that variable. What you can do is use the OnCalc
where you calculate the value in the Detail band and update the value in the
variable in the group footer as well. This way you don't have to code
another OnCalc for the group footer variable. It will have a group based
total, because it gets reset on every group break as defined in the timing
dialog of that group footer variable.
