flexfield, as the name suggests, is a flexible data field that your organization can customize to your business needs without programming. A flexfield is a field made up of sub–fields, or segments. While flexfields do not require programming, they do allow you to perform significant customizations to the Oracle Applications, so they do require enough explanation for you to get the most out of the features they provide.
Oracle Applications uses two types of flexfields, key flexfields and descriptive flexfields. A key flexfield is a field you can customize to enter multi–segment values such as part numbers, account numbers, and so on. A descriptive flexfield is a field you customize to enter additional information for which your Oracle Applications product has not already provided a field.
