What control in power app can be used to refrain Approve comment?

Hi Thomas

 

I have tried to use predefine response as custome value, but i get this exception; 

 

 

Failed to retrieve dynamic inputs. Error details: 'The dynamic operation request to API 'approvals' operation 'GetApprovalTypeMetadataV2' failed with status code 'BadRequest'. This may indicate invalid input parameters. Error response: { "error": { "code": "InvalidApprovalType", "message": "'Predefined response' is not a valid approval type." } }

1. Prevent Comment Entry on Approve Action:

• Approval Type: Instead of a custom response for all, choose Predefined response with comments.
• Predefined Responses:
  • Add "Approve" without requiring comments (you can leave the comment field blank for this option).
  • Add "Reject" with a comment field (this will be mandatory for rejections).

2. Redirect to New Window on Reassign:

There are two main approaches to achieve this:

Approach A: Launch a New Browser Tab (Recommended):

1. Action: Launch a website:
   • Enter the target URL (the page you want to redirect to after reassignment).
   • Under "Behavior," select Open in a new tab.

Approach B: Open a New Power Automate Window (Limited Functionality):

1. Action: Show screen (experimental):
   • Select the desired screen from your Power Automate canvas.
   • This approach has limitations:
     • Limited customization options.
     • Users might not be familiar with navigating within Power Automate windows.

Flow Construction:

1. Trigger: When an item is created or updated (or any relevant trigger for your scenario).
2. Condition: Check if the approval outcome is "Approve" or "Reject."
   • "Approve" branch: Set the comment field to an empty string (e.g., ''). This ensures no comment is entered on approval.
   • "Reject" branch: Leave the comment field as-is. This allows users to provide reasons for rejection.
3. Action: Update the item to set the approval outcome and comment (if applicable).
4. Action (for Reassign button):
   • Choose either "Launch a website" (Approach A) or "Show screen" (Approach B) depending on your preference.

Additional Considerations:

• You might need to modify the trigger and condition based on your specific data source and approval logic.
• If you choose "Show screen" (Approach B), consider creating a user-friendly screen within Power Automate for the reassignment process.
• Explore the possibilities of flow variables and custom connectors to further tailor the behavior to your requirements.

By following these steps and considering the additional notes, you should be able to create a Power Automate flow that meets your use case for preventing comment entry on approval and redirecting to a new window on reassign.
