It sounds like there were no results, so there was nothing to get. Try this to check for results before you attempt to grab it.
function get_branch_from_ledger_id($id)
{
$rows = $this->db->select('l.*,a.branch_id')
->from('ledger l')
->join('account_group a','a.id = l.accountgroup_id')
->where('l.id',$id)
->get();
return $rows ? $rows->row()->branch_id : false;
}
