A locally saved interactive Power BI report with checked measures, site filters, source CSVs and a tested refresh handoff.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Two typed source queries and baseline counts.
  • Inspected one-to-many relationship.
  • Three explicit checked measures.
  • Site slicer, cards, verification table and dated chart.
  • Local report, source files and refresh handoff.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Rows and measures reconcile.
  • Site filters affect the intended data.
  • Visual labels and date ordering are clear.
  • Refresh and local handoff are reproducible.

Before you begin

The idea in everyday life

Build a local interactive report for fictional workshop attendance and capacity.

The idea

A report begins with a known unit of data, not a chart.

Follow along

Import a defined dataset — guided practice

Load two CSVs and confirm rows and columns before making visuals.

Use free Power BI Desktop on a supported 64-bit Windows computer; check the linked current system requirements and installation policy. No cloud sign-in, subscription or publishing is needed. Save sessions.csv and sites.csv in one stable practice folder. Sessions are S1 N Jan 15 8/10; S2 S Jan 15 6/10; S3 N Feb 15 7/10; S4 S Feb 15 5/10; S5 N Mar 15 4/10; S6 S Mar 15 9/10 (all dates 2026; values attended/capacity). Sites: N=North, S=South. Follow lessons cumulatively and save report.pbix locally. Menu/pane labels can vary slightly with monthly releases; use the named feature.

  1. 1. Open Desktop

    Start a blank report. Dismiss optional sign-in prompts for this local exercise. Use Get data > Text/CSV for sessions.csv.

    You should see: A preview shows six data rows and five columns.

    Previewing confirms the expected source before loading.

  2. 2. Load the first table

    Choose Transform Data, rename the query Sessions, and keep its five columns.

    You should see: The query represents one session per row.

    A meaningful table name makes later formulas readable.

  3. 3. Add the lookup

    In Power Query choose New Source > Text/CSV, select sites.csv and rename the query Sites.

    You should see: Two rows map N to North and S to South.

    The lookup stores one label per site ID.

  4. 4. Record baseline counts

    Write Sessions=6 and Sites=2 in report-checks.md.

    You should see: The source counts are known before transformations.

    Unexpected row counts can reveal a wrong file or delimiter.

Now change one thing

A source has 8 session records plus one header. How many data rows should its preview show?

Your work

What to finish

Two named imported queries and a row-unit/count note.

Common mistake

Watch for this

Treating an automatically guessed type or delimiter as verified.
