PL-900 EXAM TOPICBEGINNER FRIENDLY~5 MIN READ

For years, building a Dataverse table meant clicking through a designer — New table, name it, add column, choose data type, set requirements, repeat. Copilot in Dataverse changes that. Now you describe the table you want in plain language, and Copilot creates it for you. The PL-900 study guide explicitly lists this as an exam objective, so it pays to know how it works.

What Is Conversational Table Building?

Copilot is the AI assistant built into the Power Apps and Power Pages maker portals. When creating a table in Dataverse, you can choose to start a conversation with Copilot instead of opening the traditional designer. You describe what the table is for, Copilot proposes a name, columns, and data types, and you can accept, reject, or refine the suggestions through follow-up messages.

Key Concepts to Know for the Exam

What Copilot Can Do

  • Create a new table — from a description like “a table to track training sessions.”
  • Add columns — with appropriate data types based on context (text, number, date, choice, lookup, etc.).
  • Modify columns — rename, change requirement level, or adjust descriptions through conversation.
  • Generate sample data — populate the new table with example rows so the maker can test immediately.
  • Suggest improvements — recommend additional columns or relationships that fit the described scenario.

Where to Find It

Conversational table building lives in Power Apps Studio (when adding a table to a solution) and the Tables area of the maker portal. When creating a new table, the maker chooses “Describe the new table” and starts typing or speaking to Copilot. Some experiences also let you upload a document or spreadsheet, and Copilot suggests a table structure based on its contents.

How It Fits With Other Dataverse Tools

Copilot doesn’t replace the traditional table designer — it sits alongside it. Once a table is created through conversation, the maker can switch to the standard designer at any time to fine-tune relationships, business rules, security, and views. Conversational creation is the on-ramp; the designer is still there when you need precision.

Creating a Table With Copilot — Step by Step

  1. Open the maker portal — go to make.powerapps.com and select your environment.
  2. Choose Tables — in the left navigation, then select New table.
  3. Pick “Describe the new table” — instead of the standard designer.
  4. Type or speak your description — in plain language, including the columns or status choices you want.
  5. Review and refine — follow up with Copilot to add, remove, or rename columns or change types.
  6. Save — Dataverse creates the table, columns, and metadata in your environment.

The Business Value

  • Faster table creation — minutes instead of clicking through a designer for every column.
  • Lower barrier for new makers — no need to learn data-type names; describe the column in plain words.
  • Better starting schemas — Copilot suggests sensible columns and types based on the described scenario.
  • Iterative refinement — follow-up messages let makers adjust the design without restarting.
  • Sample data on demand — instantly populate the table to test apps and flows.
  • Governed and secure — Copilot respects environment boundaries, DLP policies, and the maker’s permissions.

Key Takeaways

For PL-900, focus on what conversational table building is, where it lives, and how it complements the traditional designer.

  • Copilot in Dataverse lets makers create new tables and add or modify columns through natural-language conversations.
  • It generates schema (tables, columns, types) and can produce sample data on request — it does not replace the traditional designer for advanced settings.
