Power BI Enhancements You Need to Know – Part 2: OneLake + Power BI

 

Meet OneLake – The OneDrive for All Your Data

Microsoft Fabric introduces OneLake, a centralized data lake that acts as a single, unified storage layer for the entire organization. Think of it as OneDrive for your enterprise data, but smarter, governed, and tightly integrated across all analytics workloads.

Why OneLake Matters for Power BI Users

Before OneLake, Power BI often depended on:

  • Duplicated datasets across teams and reports

  • ETL pipelines just to make data usable

  • Disconnected data sources leading to inconsistency

But now, with OneLake, Power BI gains superpowers:

No More Data Duplication

Data is stored once and reused everywhere. You don’t have to keep importing or creating multiple versions of the same data.

Cross-Team Collaboration

Everyone: data engineers, analysts, scientists, accesses the same data foundation, ensuring consistency across reports and insights.

Native Connectivity

Power BI directly connects to Lakehouses, Warehouses, and other Fabric items, with no middle layers or staging copies.

Performance Boost via DirectLake Mode

This integration allows Power BI to query parquet files directly from OneLake, without needing to import data or rely on slow DirectQuery setups.

OneLake Transforms Power BI Into a Full Data Citizen

With this shift, Power BI is no longer just a "consumer" of data, it becomes an active participant in your data ecosystem:

  • It reads directly from your enterprise-grade storage (OneLake)

  • It adapts instantly to new Lakehouses or Warehouses

  • It respects governance, security, and lineage set at the data platform level

It’s not just about creating visuals anymore, it’s about operating inside a truly connected, governed, and scalable platform.

Import Microsoft Planner Data into Power BI Using Power Automate and SharePoint

Image
  In this guide, we’ll cover how to bring task data from Microsoft Planner into Power BI for analysis, using Power Automate and SharePoint as intermediaries. Since Power BI currently lacks a direct Planner connector, Power Automate lets us fetch the data from Planner and save it to SharePoint as a JSON file, enabling Power BI to access it on a scheduled basis. Prerequisites Before you begin, ensure you have: Access to Microsoft Planner  – to view and retrieve Planner task data. Power Automate License  – access to create and run Power Automate flows. SharePoint Access  – a SharePoint site to store JSON files. Using SharePoint simplifies the setup, as it doesn’t require a premium Power BI or Power Automate license. Power BI Desktop  – to set up and configure the JSON data connection and publish the report. Microsoft 365 Account  – for authentication, as we’ll be connecting Power BI to SharePoint through your organization’s Microsoft 365 credentials. Step 1: S...

Append vs. Merge in Power BI: Key Differences and Use Cases Introduction When working with data in Power BI, combining datasets is often essential for creating comprehensive reports. Power BI offers two primary methods for combining tables: Append and Merge . While both are used to consolidate data from multiple sources, they work in different ways and are suited for different scenarios. In this blog, we will explore the key differences between Append and Merge in Power BI, along with practical examples to help you choose the right approach for your data needs. 1. What is Append in Power BI? Append in Power BI is used to combine rows from two or more tables into a single table. The structure of the tables being appended should be similar (i.e., they should have the same columns), as Append simply stacks the rows on top of each other. Key Features of Append: Row Combination : Append combines rows from multiple tables, one after the other. No Column Matching : Columns are not matched b...
