Dashboards, Alerts & Subscriptions

Create Power BI dashboards by pinning visuals, set up data-driven alerts, configure email subscriptions, and manage content endorsement (promote and certify).

Dashboards, alerts, and trust

β˜• Simple explanation

A dashboard is a highlights reel. You take the most important visuals from different reports and pin them onto a single page. It’s your at-a-glance view β€” like a car dashboard showing speed, fuel, and temperature all in one place.

Alerts notify you when a metric crosses a threshold. Subscriptions email report snapshots on a schedule. And endorsement (promote/certify) marks trusted content so users know which datasets are the β€œofficial” ones.

Dashboards in Power BI service are single-page collections of pinned visuals (tiles) from one or more reports. Unlike reports, they don’t have filters or slicers β€” they’re overview surfaces. Data alerts can be set on dashboard tiles to trigger notifications when values exceed thresholds.

Endorsement is Power BI’s trust framework: Promoted content is recommended by its owner, while Certified content has been verified by a designated authority. This helps users find reliable datasets in large organisations.

Dashboards vs reports

Dashboards are for monitoring; reports are for analysis

Creating a dashboard:

  1. Open a report in the Power BI service
  2. Hover over a visual β†’ click the pin icon πŸ“Œ
  3. Choose β€œNew dashboard” or pin to an existing one
  4. Repeat for visuals from any report

Riley at Coastal Fresh (πŸ›’) creates an executive dashboard with tiles from three reports:

  • Revenue card (from Sales report)
  • Inventory status (from Operations report)
  • Customer satisfaction score (from Survey report)

Data alerts

Alerts trigger notifications when a dashboard tile’s value crosses a threshold.

Alert SettingDescription
ConditionAbove, below, or equal to a value
ThresholdThe trigger value (e.g., revenue below $50K)
FrequencyAt most once an hour, or once a day
NotificationPower BI notification centre + optional email

Requirements: Classic data alerts work on dashboard tiles β€” specifically cards, KPIs, and gauges. They’re not available on chart or table tiles. Note: Power BI is also introducing Fabric Activator alerts that work directly on reports for more flexible alerting scenarios.

Kenji at Apex Manufacturing (🏭) sets an alert: if daily production falls below 800 units, he gets an email immediately. This lets him respond to production issues without constantly watching the dashboard.

Subscriptions

Subscriptions email a snapshot of a report page or dashboard on a schedule.

How to set up:

  1. Open a report/dashboard β†’ Subscribe (envelope icon)
  2. Choose recipients, frequency (daily, weekly, after refresh)
  3. Set the page to capture and optional filters
  4. Recipients get a PNG image of the page + link to the live report

Dr. Ethan at Bayview Medical (πŸ₯) subscribes department heads to a weekly compliance summary β€” every Monday morning they receive the latest compliance scores in their inbox.

Endorsement: promote and certify

In large organisations, users need to know which datasets and reports are trustworthy.

Promoted = 'I recommend this.' Certified = 'The org has verified this.'
LevelWho Can Do ItWhat It MeansBadge
NoneDefaultContent has no endorsementNo badge
PromotedContent owner/adminOwner recommends this as reliableBlue badge
CertifiedDesignated authority (configured by admin)Verified by organisation as trustedGold badge with checkmark

How to promote: Settings β†’ Endorsement β†’ Promoted How to certify: Requires admin-configured certification authority. Settings β†’ Endorsement β†’ Certified

Nadia at Prism Agency (πŸ“Š) promotes her curated client datasets. The agency’s data team certifies the shared company-wide campaign performance dataset β€” so everyone knows to use it instead of creating their own.

πŸ’‘ Exam tip: promote vs certify
  • Promoted: Any content owner can promote their own content. It’s a personal recommendation.
  • Certified: Only designated certifiers (configured by the Power BI admin) can certify. It’s an organisational endorsement.

The exam tests this distinction. If the scenario says β€œthe BI team has verified the dataset” β†’ Certified. If β€œthe report author recommends it” β†’ Promoted.
