SecuritySuite - SuiteCRM and CE Teams

Hello, I'm trying to add a functionality to SugarCRM using the Securty Suite. I want to add automatically the teams when i create a case, and for that, this support page was very helpful as i used part of the code that i saw in another post: $securityTeam = new SecurityGroup(); $securityTeam->retrieve_by_string_fields(array('name' => $field_securityGroup )); $bean->load_relationship('SecurityGroups'); $bean->SecurityGroups->add($securityTeam->id); $bean->save(); The problem is that i don't know the name of the team, i just know the id of the user that belongs to the teams i want to add. I know that i can do this with a query to the securitygroups_users table, but i want to do this without doing queries to provide a better performance. There are another way i can do this? Thanks in advance for your help! Regards, Joana Lopes da Fonseca
