Title: PL-300 Practice Question – Where to Modify Relationships in Power BI Desktop

When you’re building a Power BI semantic model, understanding where to define and adjust relationships between tables is fundamental — both for the PL-300 exam and for real-world report building.


📌 Question:

You have begun creating a Power BI Semantic model by connecting to a SQL Server database with multiple tables.

You now need to modify the relationship between the tables.

Which interface should you use in Power BI Desktop? (Select only one answer)

  1. Table view
  2. Model view
  3. DAX query view
  4. Report view

Correct Answer: 2. Model view


🧠 Why Model View is the Correct Choice:

  • Model View in Power BI Desktop gives you a diagram-like interface showing all tables in your semantic model.
  • It allows you to:
    • View existing relationships.
    • Create new relationships by dragging fields between tables.
    • Edit relationship properties (cardinality, cross-filter direction, etc.).
    • Delete relationships if needed.

Without the correct relationship setup, aggregations, filtering, and DAX measures can produce incorrect results.


🚫 Why the Other Options Are Incorrect:

1. Table View

  • Lets you see raw data from a table.
  • You can’t create or edit table relationships here.

3. DAX Query View

  • Used for writing and testing DAX queries.
  • Not intended for visual relationship editing.

4. Report View

  • Used to build visuals, dashboards, and reports.
  • Relationships must already be defined before the Report View can interpret cross-table filtering correctly.

📌 Pro Tip for PL-300:

If the question involves relationships, cardinality, or model diagram editing, the answer is almost always Model View.

In the exam, remember this mental shortcut:

Relationships live in the Model View — not in data tables, queries, or reports.
