Users may see incorrect data in reports and downstream apps using result set caching in Microsoft Fabric
Start Time: 2025-06-16 09:00(JST)
Last Update: 2026-03-06 05:58(JST)
Status: Service Restored
Affected Service: Power BI
This issue specifically impacted results with the queries in Fabric
Data Warehouse and SQL Analytics Endpoint when the result set caching feature
was active. The results may have included incorrect cached items or excluded
relevant cached items.
We disabled the result set caching feature as of February 16, 2026, to prevent
any confusion or misinterpretation of results. For any reports or downstream
apps using cached results on or prior to February 16, 2026, from the Data
Warehouse or SQL Analytics Endpoints, users will need to manually refresh to
obtain relevant results. This will ensure that these other apps don’t continue
to work with potentially incorrect results.
