Crystal Report: Unhide data if it is On first Record of the page

Question

I have here a data that will suppress when on change of a field. And I made to suppress it. But I'm having trouble on displaying the record on the first line. Even it is duplicate record I need to display it.

I have tried

Not OnfirstRecord And
if ({onChangefield} = previous({onChangeField})) then
true
else
false

But it doesn't unhide the first line of the record.

Please help.

Thank you in advance. :)

Edit:

It's not "on change field", it is a key field that if this key field is duplicate then the data will suppressed.

Answer 1

One way you can do is to print the numbers on the records then supress according to that:

1. Create a formula @Reset :

   Shared Numbervar count;
   count:=0;
   

2. Create a formula @Count

   Shared Numbervar count;
   count:=count+1;
   

3. Create a formula @display

   Shared Numbervar count;
   count;
   

Now write your formula as:

Shared Numbervar count;

If(count=1) And ({onChangefield} = previous({onChangeField})) then
true
else
false

Answer 2

You just misplace the Not OnfirstRecord I do like below and it's working.

if Not OnfirstRecord And ({onChangefield} = previous({onChangeField})) then
true
