There are different exporting concepts in Power BI and Synoptic Panel.
Exporting Reports to PDF or Power Point file
This is a feature of Power BI that allows you to export your report to a PDF or Power Point file. Unfortunately, this feature is supported only by Synoptic Panel Lite, since it’s certified by Microsoft. If you try to export a report containing Synoptic Panel to a PDF or Power Point file, you will get a placeholder error where the visual was placed.
