Power BI Dataflow Gen1 is labeled legacy but remains supported. Teams should inventory dependencies, then keep stable Gen1 flows, test Gen2 side-by-side, or plan controlled migration based on licensing, change needs, and Fabric access.

Microsoft Fabric stopped auto-creating default semantic models for lakehouses and warehouses. Import-based Power BI reports are largely unaffected. Owners of auto-generated models should inventory dependents before rename or delete. Task Flows and Direct Lake remain optional,…

Fabric Notebooks fit coded, large-scale data prep, not routine Excel cleanup or Power BI model fixes. Start with the simplest supportable tool; adopt a notebook only when custom logic, volume, reuse or named engineering ownership is required.

Report builders often see stakeholders export dashboard data to Excel. This guide separates jobs that belong in dashboards from those that need Excel or a governed middle path, using four key terms and a decision table.

Inherited Power BI reports often lack docs on ownership, refresh, gateways, and backups. Week one is observation-only: record known state, mark pass/fail/unknown, and avoid edits that deepen mystery before safe changes.

Managers often ask for last week's Monday report version after it has been refreshed and overwritten. SharePoint history restores files but does not track source data, QA checks, or changes. This content covers the minimum four items to save weekly—raw source snapshot, refreshed…

Power BI scheduled refresh fails with vague errors. Analysts must capture refresh history, settings, gateway status, and source changes before escalating. Desktop vs service behavior narrows the cause. Separate credential, gateway, and schedule checks prevent mixed signals.

Analysts lose hours fixing recurring Excel exports that break merges due to renamed columns, dropped fields, or wrong versions. A source file agreement documents file location, patterns, required columns, and exception ownership before rebuilding the Power Query workflow.

Month-end reporting packs contain source cleanup, linked workbooks, formulas, manual adjustments, KPI definitions, commentary, and sign-off notes. The migration question is not whether the pack moves to Power BI, but which components are repeatable reporting outputs versus human…

Power BI Dataflows enable centralized data transformation in the cloud, replacing repetitive ETL in isolated reports. Analysts build once and reuse across semantic models and Excel, cutting errors and inefficiencies. Draws on Jessica Jolly's expert methods for enterprise scalability.

Excel has shifted from manual formulas and rigid interfaces to AI-assisted intent interpretation via Microsoft 365 Copilot and Work IQ context. Legacy tools like VLOOKUP and manual Power Query are obsolete, replaced by XLOOKUP, natural language processing, GROUPBY, and in-app AI shortcuts. This guide maps 2023 techniques to 2026 native capabilities, eliminating fragile pipelines and enabling automated multi-step logic.

Power BI DAX workflows have shifted from manual authoring to AI-assisted generation and native query environments. This briefing maps legacy techniques to current Fabric-era tooling including Copilot, DAX Query View, and visual calculations.

Power BI Dataflows Gen1 evolved into Fabric Dataflow Gen2 by decoupling transformation from storage, adding Copilot for AI-powered M-code generation, and enabling routing to Lakehouse, Snowflake, or SQL. Governance shifts to KQL and Real-Time Intelligence. Legacy Premium SKUs retired for Fabric capacities. This update details the full architectural overhaul and step-by-step build process.

Power BI totals diverge from Excel for seven ordinary reasons: filters, refresh timing, Power Query steps, relationships, non-additive DAX, RLS, and manual Excel adjustments. Checking them in order yields a defensible explanation for stakeholders.

Excel-strong reporting owners face broken refresh, disputed KPIs, and manual cleanup across Power BI, Power Query, and Fabric. Matching the failure to the bottleneck—not the product menu—avoids wasted license spend. A Report Tool Decision Record clarifies ownership and next…
