SecuritySuite - SuiteCRM and CE Teams

am using logic hook with $sg->addGroupToRecord

Yes, that is an unused, internal function. If you are using it, which is fine, you will need to check to see if an existing record exists prior.

This function was for pre-6.3.0 in the Mass Assign functionality and was used at that time in this manner:

                $query = "SELECT * FROM securitygroups_records WHERE securitygroup_id='$groupFocus->id' AND record_id='$id' AND module='$sugarbean->module_dir' AND deleted=0";
                $db = DBManagerFactory::getInstance();
                $result = $db->query($query);
                $row = $db->fetchByAssoc($result);
                if (empty($row))
                {
                    SecurityGroup::addGroupToRecord($sugarbean->module_dir, $id, $groupFocus->id);
                }

Hope this helps!
