Report Model and function override
I created Report.php custom model to override addContactInformation function to allow the contact to access all incidents in all Orgs with no limitations.
Now the logged in contact have access to all incidents when exporting a report and I'm using a filter to limit the result.
So far this is working as expected for me, however, what I need really is to allow the contact to export all incidents for their Org and any other Org listed as a child Org under.
If I remove the override, the contact can only get incidents in their Org only, not for other Orgs listed under.
