Which data type is concerned with the setup of forms structure?

The data type that is concerned with the setup of forms structure is associated with the setup data type. This data type is specifically focused on configuring and defining the structure needed for forms within the system. It lays the foundation for how data will be presented and interacted with through various forms in Workday, ensuring that the necessary fields, options, and layouts are correctly established.

In context, configuration data might encompass broader settings and parameters for the system, while operational data typically relates to ongoing business functions and activities. Transaction data is more about the actual records and activities that occur as part of business processes. Therefore, while all these data types play essential roles in the overall functioning of Workday, the setup data type is uniquely focused on the preactivity structural elements, making it the correct choice for this question.
