When civicase is configured to have multiple case clients, the summmary report (report class: CRM_Report_Form_Case_Summary) shows one line for each client.
I'm trying to change this to show only one line per case. I've created a copy of the above report and i'm trying to change the group by clause, currently it's
public function groupBy() {
$this->_groupBy = "";
}
I'm looking for some pointers to how to change this to group by CaseID.
Is this the right way to go and if so what would i need the function to say.
