How can you see general report information such as the document author and the document creation date?

The Query Properties button opens configuration settings for the data query such as max rows and query timeouts, not document-level metadata like author or creation date.

The Query panel is used to build, edit, and run data queries against a data source; it does not display document properties such as author or creation date.

The pre-defined 'Query Summary' cell, when inserted into a report, displays statistics about the query execution such as the number of rows returned, not general document properties like author or creation date.

The Document Summary panel aggregates all general document properties such as the author, creation date, last modification date, keywords, and description in a single panel. It is accessed from the document properties menu and is the correct tool for reviewing metadata about the report itself rather than its data or queries.
