problem with data report

Dear Sir;

By using data environemt(having one parent table and one child) in visual basic6 i am generating a data report.
But many times it happens that on the last page of my data report i miss some data( a complete one line) which does not come there but in my other report (which is a excel report) it always comes.

May u kindly tell the reason and solution of this behaviour of data reports…..i am worried a lot as if some data is not printed in the data report there will be question of failure of my project.

I am looking for ur help…………

Thanks!!!!
