A dynamic value is a placeholder in double braces that the report replaces when it opens and whenever filters or parameters change: Sales report for {{filter.Region}}, {{date:YYYY-MM-DD}}.

Insert one

In Text and Shape, use Style → Content (or Text) → Insert dynamic value; in Rich text, the toolbar's Insert dynamic value. Or type the placeholder.

Placeholder	Becomes	Menu item
{{param.NAME}}	The value of a report or global parameter, or a system variable such as {{param.system.username}}	Report parameter value
{{filter.NAME}}	The selection of the filter component whose title or field is NAME; when that filter is All or there is no such filter, the members selected in a chart on the page (cross-filtering) for the field NAME; All when nothing is selected	Current filter selection, and the Chart fields (cross-filter) group
{{date}}, {{date:FORMAT}}	The date and time the report was opened or refreshed; default format YYYY-MM-DD	Today's date
{{user.name}}	The signed-in user	Current user
{{page.title}}	The report name	Report name

Date format codes: YYYY, YY, MM, M, DD, D, HH, H, mm, ss. Example: {{date:DD/MM/YYYY HH:mm}}.

If the report has parameters or filters, the menu lists each by name. Otherwise the inserted placeholder has no name ({{param.}}); type the name after the dot.

How they are shown

• In the editor you see the placeholders; in the report you see the values.
• An unknown parameter or filter name stays visible in the editor and is blank in the report.
• Several selected filter values are joined into one text.
• A parameter's value comes from a filter bound to it, then the URL (?NAME=value), then its default.
• In Image URLs and Web page addresses the values are URL-encoded.

Where they work

Text, Shape text, Rich text, Image URL, Web page address, and the rules of Visibility. Component titles use a different syntax, ${NAME}; see Parameters in component titles.
