Question

The case : CRUD Work Orders in Dynamics 365-Field Service through the Common Data Services OData

1. I am trying to access to Dynamics 365 Field Service' fields.

I use Python, Flask to build the webapp

2. I need to CRUD Work orders : https://docs.microsoft.com/en-us/dynamics365/customer-engagement/web-api/msdyn_workorder?view=dynamics-ce-odata-9

3. I am using the multi-tenant server-to-server authentication mechanism: https://docs.microsoft.com/en-us/powerapps/developer/common-data-service/use-multi-tenant-server-server-authentication

4. I have setup the App Registration on Azure: https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app

5. I have configured several permissions:

• Odata.FullAccess
• AX.FullAccess
• CustomService.FullAccess
• User.Read
• User.ReadBasic.All

6. I use the code-template provided by Microsoft to build my web app interacting with Active Directory and Dynamics 365

   https://docs.microsoft.com/en-us/azure/active-directory/develop/scenario-web-app-call-api-overview

Error message

Login Failure

invalid_scope
    The provided value for the input parameter 'scope' is not valid. 
    The scope 'Odata.FullAccess User.ReadBasic.All offline_access openid profile'

Do you have any idea?

Many thanks for the time you will invest in this issue

Answer 1

Based on Grant your application rights to access Common Data Service data, you need to select Access Dynamics 365 as organization users.

It is under Dynamics CRM rather than Dynamics ERP.

Odata.FullAccess is a permission under Dynamics ERP, which is not valid for your scene.
