Posted on 2008-10-13

Can any one help me.

I am running Crystal Reports 10 and wish to display any record that is duplicate. It is a single table at the moment.

This is an example....

ID  Name Age
1  Alan    18
2  Chris   19
3  Chris   19
4  Jane    20
5  Jack    18
6  Jack   18

I want to display

Chris 19
Jack 18

How is this done. I have heard of previous value etc but how is this done in formulas.

I am new as you may have noticed to Crystal Reports.

Try this

Group on the name field
Suppress the group header using a formula
Count({NameField},{NameField}) = 1

Or you can use a formula to create a more uniqque group incase he has jack 17 and jack 18.  Basically {field1}+{field2}+{field3} would be the formula.  Gorup by the formula.  And surpress based on the count like the previous poster mentioned.

I tried the above but still getting problems.
Done the following
2.Went into the Format Field of the group
3.Selected common tab
4.Selected Suppress if duplicate.
5. Put in the formula
count({NAME},{NAME}) > 1
6.Ticked and also unticked Supress if duplcate
7. OK that and ran again.

Still getting the wrong display.
I must be doing something really stupid. Sorry if I am.

I want only Jack and Chris to be displayed with their numbers.

Hope this makes sense?

The count statement needs to use your fields.

Are you using it in the SUPPRESS formula?

I am using it in the SUPPRESS formula within the suppress to duplicate option.

Hope this makes sense?

A cross tab might be an easy way to do it.
You would then show each name only once, and you could display the max age against it.
