Using Small Multiples - Border On Error

[L1102]

Hi All,

I'm creating a chart with small multiples, and everything is great until i turn on the border for the small multiples. I'll get the following errors and will need to end task for power BI in my task manager in order to get out of the error cycle. Any thoughts on what could be the issue?

We wanted to follow up as we haven’t received a response yet. Have you had a chance to review the information above? If you have any questions or need further assistance, feel free to reach out.

This is most likely a bug at the intersection of PBI_enhancedReportFormat and small multiples border rendering, amplified by the recursive SaveFormattingValues loop visible in your recent actions.

I recommend you to Disable Enhanced Report Format

Go to:

File → Options → Preview Features → uncheck Enhanced Report Format

Then restart and test the border again.

If it works, you've confirmed the bug and should report it to Microsoft via the Power BI Community or in-app feedback with this diagnostic info.

Hope this helps! Don't forget to mark as solution and thumbs up in order to keep helping others 🙂
