3647542 - Black bars displays in the PDF document generated by exporting a Story to PDF in SAP Analytics Cloud (SAC)

• When exporting a Story to PDF format in SAP Analytics Cloud, the generated PDF document contains black bars on some widgets.
• Black bars appear on tables and charts in the PDF document under specific conditions.
• The issue occurs inconsistently, even with the same Story design and export settings.

• SAP Analytics Cloud 2026.8.16

1. Login to SAP Analytics Cloud.
2. View a Story
3. Export the Story to PDF format.
4. Open the generated PDF document and observe the black bars on some widgets.

• The issue occurs when widgets in the Story do not fully render during the export process.
• The cause of this is due to the PDF export process capturing the page before the widget's query has returned data.
• There are various reasons than can cause this, such as a delay from the data source returning data, story scripting that is taking too much time, or scripting such as Application.refreshData() applied on each Page of the Story, causing the rendering process to not fully complete before the export.

• To resolve the issue, check for scripting that can affect the timing or data retrieval. For example remove the script: Application.refreshData(), on each Page of the Story.   
• Retrying the export to see if the data source will return the required data more quickly.
