Which of the following is NOT supported by a web query?

The correct choice indicates that financial statements are not supported by a web query in NetSuite. Web queries are designed primarily to extract specific data in a structured format, usually suitable for reporting or data manipulation tasks.

Financial statements, which are comprehensive reports summarizing the financial status of an organization, tend to be complex and involve aggregation of various data points, including revenue, expenses, and balance sheet items. These reports usually require specific formatting and often incorporate calculations and consolidations that go beyond the capabilities of a simple web query.

In contrast, custom records, data segments, and historical reports can usually be accessed more straightforwardly via web queries. Custom records allow users to define and pull specific data points tailored to their needs, data segments facilitate the combination of different datasets, and historical reports can be derived from existing data structures within the system, making them suitable for extraction using web queries. Hence, the assertion that financial statements are not supported makes sense within the context of the capabilities of web queries in NetSuite.
