Dataset Refresh REST API returns 415 "Model-based dataset" error
Since 2026-08-14, calling the Refresh Dataset REST API (POST /v1.0/myorg/groups/{workspaceId}/datasets/{datasetId}/refreshes) on any dataset in my tenant fails with: HTTP 415 UnsupportedMediaType {"error":{"code":"InvalidRequest","message":"Invalid dataset. This API can only be called on a Model-based dataset"}} This happens even on datasets that refreshed successfully via this exact API for weeks before that date, without any changes to the dataset itself. Manual "Refresh now" via the Power BI portal UI still works fine on the same datasets — only the REST API call fails. What I've already ruled out: Not a client bug — reproduced identically with curl using the same bearer token, bypassing my application entirely. Not just a POST/trigger issue — a plain GET /datasets/{id}/refreshes (listing refresh history) fails with the same error. GET /datasets/{id} succeeds fine and returns "isRefreshable": false, even for a standard Import-mode, on-premises-gateway-connected dataset (targetStorageMode: Abf) that worked correctly before. Not a capacity issue — my Fabric trial capacity shows Active/healthy. Checked Service Health and Known Issues in the Admin Portal — nothing matching. Possible trigger: the issue started the same day I added (then a few hours later removed) two unused Azure AD Application permissions (Tenant.Read.All, Tenant.ReadWrite.All) on my app registration for an unrelated experiment. It's been 3+ days since removing them and forcing a fresh sign-in, and the issue persists. Has anyone else seen this, or does anyone know what could cause isRefreshable to flip to false tenant-wide like this? Happy to share more details (workspace/dataset IDs, full error bodies) if useful.
How to make Power BI Slicer to show the latest forecast selected when the report loads
I have a request to show the latest Forecast selected as a default slicer when the report loads.. every 3 months new forecast will come. 2026_F1, 2026_F2, 2026_F3 like that, The slicer is a single select when the report loads the selection should be latest and the user can change the visuals will change accordingly. I use a calculated column in power bi to add a new column that will have values2026_F1, 2026_F2, Latest...... When new forecast comes 2026_F1, 2026_F2, 2026_F3, latest like that.. and i made the default selection as Latest. The user doent want to see the word latest he wants to see the forecast name instead of the workd Latest. How to do it. I know bookmarks is an option but we have so many bookmarks in that report and doesnt want to use that one .
PowerBI Workspace Not Found" Issue
Hi Team, I am trying to deploy a thin report to a Power BI workspace using a Service Principal. However, I am receiving the error "Power BI Workspace Not Found". The Service Principal has Admin permissions on the target workspace, and I am passing the correct workspace ID in the API request. Has anyone encountered this issue before? Are there any additional permissions, configurations, or prerequisites that I should verify? Any guidance would be greatly appreciated. Thanks.
Iframe continues scrolling after mouse release when interacting with Power BI visuals
Hi Community, I'm experiencing an issue with a Power BI report embedded inside an iframe. Scenario Power BI report is hosted within a custom web application using an iframe. Users interact with report visuals that support scrolling (tables, matrices, slicers, etc.). When clicking and dragging the scrollbar inside a visual, the scrolling continues even after the mouse button has been released. It appears as though the iframe or embedded report is still capturing the drag/scroll event. Expected Behavior Once the mouse click is released, scrolling should stop immediately and control should return to the page normally. Actual Behavior Scrolling persists for a short period or remains "stuck" until the user clicks elsewhere in the report or page. Environment Power BI Embedded / Power BI Service in iframe Browser: [Chrome/Edge version] Report contains tables and matrix visuals with internal scrollbars Custom web application hosting the iframe
Power BI Alternative Front End for Visualisations / Dashboards? (web native)
I’m wondering if anyone has suggestions for using the Power BI data model or DAX to create more web native dashboards for our products. We want something that looks and acts the web instead of PowerBI, but allows some of the benefits of the data model and backend. Either looking at some methods, tools or even a whole new product we can buy to sit over the top. Wish list - Allow creation of a collection of visualisations / dashboards Control styling and layout with HTML/CSS including webfonts Responsive Edit/swap a chart in the layout with the same ease as Power BI. Doesn’t live in something that looks and iFrame. I understand I’m asking for a lot and really bending what Power BI does so it might just be impossible. I’m also open to any alteratnive products that might help.
Dynamic Refresh Period Per Firm - Date Slicer Shows Global Range Instead of Firm-Specific Range
Hey all, I have a transactions dataset with multiple firms where each firm needs a different data retention period. Firm A needs 12 months of history, while Firm B needs 15 months. Users are scoped to one firm at a time via RLS. The issue: Even though the fact table correctly loads firm-specific months from Snowflake, the date slicer shows the same global date range (15 months) for both firms. Current Setup: Parameters: RefreshPeriod = "12" (default months) RefreshPeriodOverrides = "FirmB:15" (firm-specific overrides) FirmRefreshCaseSQL = generates CASE WHEN FIRM_KEY = [FirmB] THEN -15 ELSE -12 END MaxRefreshPeriod = "15" (max across all firms) Data Loading: Transaction fact table: Uses FirmRefreshCaseSQL in WHERE clause, correctly loads 12 months for Firm A and 15 months for Firm B Calendar dimension: Uses MaxRefreshPeriod, loads 15 months globally Relationships: Transaction[Transaction Date] → Calendar[Transaction Date] (many-to-one, single direction) Transaction[FIRM_KEY] → Firm[Firm ID] (many-to-one) Date Slicer: Bound to Calendar[Transaction Date] Expected Behavior: When Firm A is selected: slicer shows last 12 months When Firm B is selected: slicer shows last 15 months Actual Behavior: Both firms show last 15 months because the calendar dimension is global and doesn't know which dates belong to which firm What I've Tried: ✗ Setting parameter overrides at the report level - didn't propagate to semantic model ✗ Testing with measures - confirmed fact data is correct per firm, but slicer uses calendar dimension 🔄 Current approach: Adding a "Firm-Date Availability Bridge" table with distinct (FIRM_KEY, Transaction Date) combinations to enable filter propagation: Firm → Bridge → Calendar Questions: Is a bridge table the right approach for this scenario, or is there a simpler pattern? Should I consider making the Date↔Transaction relationship bidirectional instead? (Concerned about RLS implications) Are there any DAX-only solutions that don't require model changes? Has anyone solved firm-specific date filtering without loading separate datasets per firm? Any guidance would be appreciated! Thank you!Can we improve relationship arrow rendering in the semantic model view?
There are multiple issues with the way relationship arrows are rendered, and this image displays a few of them: (Note: I am using the web interface, via Edge.) Is there anything I can do to combat this confusing display pattern? An arrow that points ambigiously is worse than no arrow at all. If anyone in power is reading: please either give us more control over how these are rendered or make them behave logically. Example: in the first and last relationships shown above, I know that the arrow has rotated because the connecting lines are not perfectly aligned, but these lines should automatically align vertically as the others have and the arrow should only rotate if there are visible horizontal connectors extending out its sides.
