You mean to say you require report by Namewise Car wise .

Create a key on table and Create report using report wizard.

I need to make following make creditbalance(number of line) variable =0 before it go to another car no because my proplem is

it make accumlation as serial to all car no

ex

car no 101 1 ,2,3

car no 102 1,2,3 not 4,5,6

meaning i need to increase every line by one to every car no after this assum value to 0 to start another grouping to another car

Is data stored in table ?

Then Create a key on table and create a report using wizard.
