=item new()

create an object. Do not use it directly, instead use:

    use Kernel::System::ObjectManager;
    local $Kernel::OM = Kernel::System::ObjectManager->new();
    my $TicketResponsibleSetObject = $Kernel::OM->Get('Kernel::System::ProcessManagement::TransitionAction::TicketResponsibleSet');

=cut

sub new {
    my ( $Type, %Param ) = @_;

    # allocate new hash for object
    my $Self = {};
    bless( $Self, $Type );

    return $Self;
}

=item Run()

    Run Data

    my $TicketResponsibleSetResult = $TicketResponsibleSetActionObject->Run(
        UserID                   => 123,
        Ticket                   => \%Ticket,   # required
        ProcessEntityID          => 'P123',
        ActivityEntityID         => 'A123',
        TransitionEntityID       => 'T123',
        TransitionActionEntityID => 'TA123',
        Config                   => {
            Responsible => 'root@localhost',
            # or
            ResponsibleID => 1,
            UserID        => 123,               # optional, to override the UserID from the logged user
        }
    );
    Ticket contains the result of TicketGet including DynamicFields
    Config is the Config Hash stored in a Process::TransitionAction's  Config key
    Returns:

    $TicketResponsibleSetResult = 1; # 0

    );
