Use Variable Library in Power BI report / semantic model

Hi FreddyH,

Variable Libraries in Microsoft Fabric integrate well with Data Pipelines, as pipelines support environment-specific variable sets natively. However, Power BI Reports and Semantic Models currently do not have native support for dynamically using Variable Libraries at runtime like pipelines do.

Reports and semantic models can't automatically change values based on the active workspace variable set. If you try to retrieve variables using a web query (such as Azure DevOps JSON), you'll find that explicit parameters like branch name or endpoint are needed, which can lead to hard-coding unless you externalize these parameters.

One solution is to use Power Query parameters or semantic model parameters and manage their values with deployment pipeline rules. Deployment pipelines let you override parameter values for each stage (Dev/Test/Prod), so you don't have to hard-code branch names in your query. This is the closest supported method for reports and semantic models.

Another approach is to keep configuration in a central table (such as Lakehouse, Warehouse, or a Key Vault-backed source) and let the semantic model read the configuration based on the workspace or environment. This removes branch dependency and keeps configuration external.

While Power BI reports and semantic models can't directly use Variable Libraries yet, you can achieve similar results with parameters and deployment pipeline rules or a central configuration source. If you need more direct integration with Variable Libraries, submitting feedback to the Fabric Ideas forum is recommended, as this feature is not currently available.
