Manage topics in Copilot Studio

Topic errors

When you save a topic, Copilot Studio reports any issues in the topic.

• Errors stop your copilot from working. You must fix them before you can publish your copilot.
• Warnings don't stop your copilot from working, but might cause some topics not to work as expected. You should fix warnings when you see them.

On the Topics page, you can see if a topic has errors, and the number of errors, in the Errors column. This page only shows errors because, unlike warnings, errors prevent your copilot from working.

View topic errors

1. Open your topic from the Topics page.

2. Select Topic checker on the toolbar.

   The Topic checker panel appears, reporting errors and warnings for your topic.

3. Select an error to go directly to the node that contains the error.

Topic status

Topics can have a status of On or Off to indicate whether they can be used or triggered in a copilot conversation. By default, new topics are created with their status set to On.

When a topic is On, it triggers as expected. Topics get triggered as a result of its trigger phrases or when another topic redirects to it.

When a topic is Off:

• The topic icon turns gray with an indicator.
• The topic doesn't trigger at all.
• The topic doesn't trigger when trigger phrases are used in a conversation or if another topic redirects to it.
• The topic checker identifies an error if another topic redirects to the Off topic.
• When you publish a copilot, all topics are published, whether they're On or Off.

Turn a topic on/off

To change the status of a topic, select the More options icon (…) next to your topic name and use the Status toggle.

Copy a topic

After you create a few topics, you can use a previous topic as a baseline when creating new topics.

In the Topics page, select the More options icon (…) next to your topic name, then select Make a Copy.

This duplicates the selected topic with (Copy) added to the name. All the topic content, such as the description, trigger phrases, and the entire conversation, is copied over to the new topic.

To prevent confusion with the original topic, which has the same trigger phrases, consider turning Off the new topic.

When you're done editing the new topic, turn it On to test it. When it's ready, publish the new topic.

There's no limit to the number of times you can copy a topic. Each topic has its own internal ID.

Rename a topic

You can use the authoring canvas toolbar to quickly rename a topic. In the toolbar, select Topics, then select the topic name in the list. On the topic page, select the topic name, type a new name and then press Enter.

Redirect to another topic

To shift the conversation from a topic to another one without starting over, add a Redirect node. When the conversation reaches the end of the destination topic, it resumes in the originating topic by default. You can insert more nodes after the Redirect node as desired.

1. Select the Add node icon below the node where you want the transition to occur, point to Topic management and select Go to another topic.

2. Select the desired destination topic from the list.

3. Pass variables between topics if needed. If the topic you're redirecting to requires input variables or is expected to return output variables to the originating topic, enter or select a value for each one.

4. Save your topic, and then use the Test copilot pane to confirm that your copilot successfully calls the destination topic.

End the current topic or all topics

By default, a redirected conversation returns to the originating topic at the end of the called topic. To exit a topic, or to end the conversation, use the End current topic node or the End all topics node.

• An End current topic node ends the current topic. If the current topic is called from another topic, the conversation returns to the original topic immediately. A common use of this node is in a condition branch. One branch exits the topic early, while another branch continues the current topic.

• An End all topics node ends all active topics immediately. Your copilot considers the next message from the user as the first message in a new conversation.

  To let the user know that the conversation is over, add an End Conversation node before the End all topics node.

Many of the system topics use these nodes to control how conversations end or start over. Learn how to use system topics.

Topic errors

When you save a topic, you're notified if there are errors or warnings. Warnings don't stop the copilot from working, but can cause individual topics to not work as expected, so you should fix them when you see them.

Errors prevent the copilot from working and must be fixed before you can publish it.

You can see if there are errors in a topic in the Errors column of the Topics & Plugins page.

Select the error count to open the authoring canvas to go to the error location. Select Topic checker to see a list of the errors. Selecting each error goes directly to the error.

Types of errors

There are four types of errors that appear in the topic checker and in the authoring canvas:

• Node: The entire node is incorrect and highlighted red.
• Field: The field is likely missing required data and highlighted red.
• Expression: The expression might be invalid and is highlighted red.
• Variable deletion: A variable in a topic was deleted and the error is highlighted red wherever the variable is used. A deleted variable causes the variable to become "orphaned" and must be removed or replaced.

Topic status

Topics can have a status of On or Off to indicate whether they can be used or triggered in a copilot conversation. By default, new topics are created with their status set to On. Change the status using the toggle in the Status column of the Topics & Plugins page.

When a topic is On, it triggers as expected. Topics get triggered as a result of its trigger phrases or when another topic redirects to it.

When a topic is set to Off:

• The topic doesn't trigger at all.
• The topic doesn't trigger when trigger phrases are used in a conversation or if another topic redirects to it.
• The topic checker identifies an error if another topic redirects to the Off topic.
• All topics are published, when you're ready to publish your copilot, whether they're On or Off.

Control the status from the Status column, toggling it On or Off.

By default, new topics are created with their status On.

Copying a topic

After you create a few topics, you can use a previous topic as a baseline when creating new topics.

On the Topics page, select the More actions icon (⋮) next to your topic name and select Make a copy.

This creates a duplicate of the selected topic with (Copy) added to the name. All the topic content—the description, trigger phrases, and entire conversation—is copied over to the new topic.

A copied topic has its status Off by default when copied to avoid confusion on which topic triggers, since the trigger phrases are the same as the original topic.

Once you're done editing the new topic, you can turn it On to test it in the Test your copilot pane. When you're ready, publish the new topic.
