I am new to Crystal Reports 2008. I have a question about sub-reports.

I work for a manufacturing company that has a database of part numbers.

I have a main report that gets part numbers for a widget and passes the part numbers to a sub-report that in turn passes back all the information about the part numbers.

 

When the main report passes a null value to the sub report the sub report passes all nulls back to the main report and does  not continue to the next part number. Please let me know if you can help me with this.
