Hi, I getting duplicate rows while developing a report. i am using single table only.
Ex:                                                           Expected:
 ID      Name                                 ID               Name
 01      AAA                                    01              AAA
 02      BBB                                     02             BBB
 01      AAA                                     03             CCC
 03      CCC
 02      BBB
 
In this case how to remove the duplicates, and when i count the rows  it will show only 3,
 
Can you help me how to do this
 
Thanks in Advance
 
Vijay

Crystal Reports has a function called PreviousValue() that you can use in the Suppress property to suppress the section when the current value is equal to the previous value. Using your own field name, put this in the Suppress property.
 
{table.fieldname} = PreviousValue({table.fieldname});
 
I have the all the Crystal functions documented with sample code in my Encyclopedia books. You can find out more about my books at Amazon.com or reading the Crystal Reports eBooks online.

Oh yeah - for this to work you need to group by ID so that they are ordered next to each other. Otherwise, the PreviousValue() function won't ever have a match.
