Only show first created incident

Content

Hi All

OK so we have a custom object that is related to the incidents table so we can relate an entry in the said CO to many incidents.

We have then created a standard grid report that shows all incidents associated to the CO entry.  Now what I want to do is rather than the report display all the incidents we just want the 1st one created to show

Everything we try just displays all the incidents.  Anyone have any idea on how we do this ?

Cheers!
