25.12 Lineage View and Usage Metrics

In short: Lineage view shows sources → semantic models → reports → dashboards.

Start with a problem

Raja wants to change a column, but does not know which reports use the model.

Explain simply

Lineage view shows sources → semantic models → reports → dashboards. Usage metrics show who views a report.

Show the data

Source Semantic model Reports
Orders SQL Maharashtra Sales Sales Overview, Delivery
Targets Excel Maharashtra Sales Sales Overview

Fictional sample data. Practice file: visuals_orders_apr_may_2026.csv (source: src/practice/).

Demonstrate

  1. Workspace › switch to Lineage view.
  2. Click the Maharashtra Sales model › Show impact across workspaces.
  3. Open a report › … › Open usage metrics report.

Show the result

Your result should look like this (fictional sample):

Check Result
Impact 2 reports, 1 dashboard
Views last 30 days Sample: 120

Explain what happened

Lineage shows dependencies, so you know whom to warn before a change.

  • Notify contacts from impact analysis.

Detailed reference for this lesson:

Lineage answers "which model does this report stand on?". Usage metrics answer "who opens it?".

In a workspace, switch the view from List to Lineage. You should see sources feeding semantic models, models feeding reports, and reports feeding dashboards. Before you rename a column, open lineage and see which reports sit downstream. Impact analysis, where the tenant shows it, lists those reports.

Usage metrics (on the report menu, View usage metrics, name varies) shows views over time and which pages people open. It does not show whether the number was correct. A report with high views and a wrong measure is still wrong. Metrics can be delayed, and the report Microsoft generates has changed between "classic" usage metrics and newer workspace monitoring. Read the dates on the metrics page before you quote them in a meeting. Do not invent a view count.

Worked example. You plan to remove Orders[Discount]. Lineage shows two reports on that semantic model: the executive page and the Kolhapur city page. You check both for the discount measure before you delete the column. Usage metrics only tell you that Rani opened the executive page this week. They do not tell you that the discount card is unused. Look at the page yourself.

Ravindra Bagale's Tip

Many students delete a measure because "usage metrics did not mention it". Usage metrics count page views, not field use. Lineage may not be field-level either. Open the report and check the Data pane, then delete. Don't make this mistake!

Fix common mistakes

Wrong result Reason Correction
Broke a report in another workspace Did not check impact Run impact analysis
Usage metrics empty New report / setting off Wait or ask admin
Deleted model still used No lineage check Check lineage

Practise independently

Practice task

Before renaming City, what should Raja check?

Hints
  • Impact.
Solution

Lineage impact analysis on the semantic model.

Think like a professional

Impact analysis before change is standard practice in mature teams.
