Hello, How to get CustomerIDs from a customer ? I thought it was sommething like : $Self->{CustomerUserObject} = Kernel::System::CustomerUser->new(%Param); ... my @CustomerIDs = $Self->{CustomerUserObject}->CustomerIDs( User => 'bernard.chambon@cc.in2p3.fr', ); but, after setting CustomerIDs to MY_COMPANY for this customer (Username='bernard.chambon@cc.in2p3.fr') This code doesn't get this value (MY_COMPANY) but something that looks like the id (bernard.chambon@cc.in2p3.fr) Do I miss something ? Do I have to retrieve CustomerIDs from DB ? I did it , it's ok. Best regards ps : mysql> select customer_id, customer_ids from customer_user where customer_id = 'bernard.chambon@cc.in2p3.fr' ; +-----------------------------+--------------+ | customer_id | customer_ids | +-----------------------------+--------------+ | bernard.chambon@cc.in2p3.fr | MY_COMPANY | +-----------------------------+--------------+ --------------- Bernard CHAMBON IN2P3 / CNRS 04 72 69 42 18
