Data entry consists of using your applications for your day-to-day operations. For key flexfields, you may want to predefine the complete codes (combinations of segment values) you want to allow your users to enter.

As your organization's needs change, you will need to perform ongoing maintenance of your flexfields. For example, you may need to define new flexfield structures or disable old structures. You may also need to add new values or cross-validation rules or value security rules.
