Is there any way to check the previous records while printing reports ?

Hello everyone,

In my report, I have a condition that "if the previous document number is same as the current document number then don't print Document Number".

But now I want to condition to be as " Check the last set of document numbers if there are any one of the document numbers same then don't print Document number".

Can I have any idea about it?

Your support will be appreciated.

Thanks
