Data importation to Dataverse using Power Query is paramount for anyone preparing for the PL-200 Microsoft Power Platform Functional Consultant exam. In essence, Power Query is a potent data collection and transformation tool that was developed by Microsoft for Excel, Power BI, and other products. Power Query provides an interactive interface for data transformation, making it an ideal tool for Dataverse data importation.
What is Dataverse?
Dataverse, formerly known as Common Data Service, is a scalable data service and app platform integrated with Microsoft Power Apps. It provides secure and cloud-based storage for your app’s data and can be used alongside Power Platform products such as Power Apps, Power Automate, Power Virtual Agents, and Power BI.
Importing Data to Dataverse with Power Query
Power Query simplifies the process of importing data into Dataverse. Traditional ways of importing data confronted complex issues like dealing with different data formats and dealing with inconsistencies in the data source. Power Query resolves these challenges by providing a rich set of transformation features and an easy to use interface.
Here is a step-by-step guide:
- Create a Dataverse table: In your Power Apps environment, you first need to create a new empty table that will host the imported data.
- Load Data in Power Query: Open Power Query and click on ‘Data’ in the toolbar. Choose ‘Get Data’ from the dropdown menu. A submenu will appear where you can select from a range of data sources such as Excel, SQL Server, Web, etc.
- Transform Data: After loading the data, Power Query presents a host of options for you to transform your data. You can filter rows, combine, rename, or create new columns, among other processes.
- Connect to Dataverse: Select ‘Dataflow’ then ‘Add a new table’. Go to ‘Power Query Online’ and select the relevant workspace in Power BI. Click on the ‘Transform data’ option.
- Load Data to Dataverse: After transforming your data and connecting to Dataverse, click on the ‘Close and Apply’ option in Power Query. This will load your data into the Dataverse table.
This process demonstrates the simplicity and power of Power Query when importing data to Dataverse. Understanding these steps is crucial for candidates preparing for the PL-200 Microsoft Power Platform Functional Consultant exam.
Practical Use Case
A practical example is the importation of sales data contained in an Excel file into a Dataverse table. Here are the steps:
- In Power Query, click ‘Data’ > ‘Get Data’ > ‘From File’ > ‘From Workbook’, and select your Excel file.
- Use Power Query functionality to transform the data if necessary (for example, removing unnecessary columns, renaming columns to match Dataverse table, etc.)
- Connect to Dataverse by selecting ‘Dataflow’ > ‘Add a new table’ > ‘Power Query Online’.
- After connecting, choose the ‘ExcelFile’ as the data source, create a new Dataflow, and choose your Dataverse environment.
- Click ‘Transform data’ to ensure the data schema from Excel matches the target Dataverse table and click ‘Next’.
- Click ‘Load’ to start loading data into the Dataverse.
- Once the process is complete, you will be notified that your data has been loaded to the Dataverse table.
By following these steps, you can utilize Power Query’s capabilities to import and transform your data into Dataverse effectively, which is an essential skill for PL-200 Microsoft Power Platform Functional Consultant exam candidates. The use of Power Query considerably simplifies the process, making it accessible and efficient for a variety of data manipulation tasks. This helps to substantially streamline processes improving overall productivity and efficiency.
