You publish a very large Microsoft Power BI semantic model to a Power BI workspace. The model refresh will take two hours. In Power BI Desktop, you limit the data you work with by using parameters. You need to update the definition of a measure. What can you use to update the measure definition without having to refresh the model in the Power BI service?

• A. ALM Toolkit
• B. Tabular Editor
• C. DAX Studio
• D. Power BI Helper

Answer: (A)

Metadata-only updates are what allow you to change a measure without reprocessing data in the service. ALM Toolkit is built for this scenario: you compare your development model (for example, the Power BI Desktop model you’ve worked on with parameters) with the deployed model in the Power BI service and apply changes directly to the deployed dataset without triggering a data refresh. This lets you update measure definitions quickly and safely in large models where a full refresh would be costly or time-consuming. The other tools are useful for different tasks (general metadata exploration, live editing, or query/testing), but none offers the straightforward metadata-only deployment to a live Power BI model like ALM Toolkit.
