Understanding Approval Rule Maintenance
Over time, your business rules might change. Perhaps you once required managerial approval for purchases over 100 USD and now you require approval only for purchases over 500 USD.
You can maintain approval rules in the same place that you create them: on the rules tab of the rule step property sheet. If you prefer to expose the rules to your users so that they can update the rules without using PeopleSoft Application Designer, you can use the Approval Step Maintenance page.
