I have an Azure Devops Process which uses a Service Principle to deploy a Power BI report from a .pbix file and updates the data source to point at the production Azure SQL server.

The outcome is that the report and dataset are deployed and the connection is updated, however the CREDENTIALS are blank (Username and Password), so in order to make it usable, someone has to log on to Power BI service, open the Dataset and update the credentials, which means there is a manual step involved in our CI/CD process.

I need help with updating the source credentials for the new data source via code so that this manual process is not needed

snippet of powerbi logging page

Any suggestion will be of great help. Thank You.

  • Hi Rohith, may I know whether you want to update the source credentials after the Azure DevOps pipeline is completed? Or do you want to use PS script to update credentials at the end of the pipeline? – LoLance Apr 30 '21 at 01:45

Here is a sample PowerShell script, using Microsoft Power BI Cmdlets, which will patch the credentials of the dataset and commented at the end are few rows, which will refresh the dataset after that (uncomment them if needed). Just replace the x-es at the top with the actual values (workspace and dataset name, application ID, etc.).

<#

Patch the credentials of a published report/dataset, so it can be refreshed.
