Dynamic data in headers and footers are fields that automatically update as the document is used. In Bluebeam-style workflows, you typically can insert fields like Date, Page Number, and Bates Number. The Date field shows the current date (or the print date) and changes over time. The Page Number field displays the current page (and can show total pages), updating as you move through the document. Bates Number is a sequential identifier that advances with each page, giving every page a unique stamp. Document Title, however, is metadata about the file and does not change from page to page or with printing. It stays the same unless you edit the file properties. Because it doesn’t update automatically in the context of headers and footers, it isn’t considered dynamic data for this purpose. So the option that is not a dynamic data option for headers and footers is Document Title.
