If one step adjustment has a negative lower bound, then there must be a step adjustment with a null lower bound.</p> </li> <li> <p>At most, one step adjustment can have a null upper bound. If one step adjustment has a positive upper bound, then there must be a step adjustment with a null upper bound.</p> </li> <li> <p>The upper and lower bound can't be null in the same step adjustment.</p> </li> </ul> <p>For more information, see <a href=\"https://docs.aws.amazon.com/autoscaling/ec2/userguide/as-scaling-simple-step.html#as-scaling-steps\">Step adjustments</a> in the <i>Amazon EC2 Auto Scaling User Guide</i>.</p>",
