We are trying to access F&O enterprise data through Odata V4. We could not find following option to register our Azure app into Ax. We are following below blog post to set up:
a) in AX go to System Administration->Setup->Azure Active directory applications. If you are using Retail SKU then navigate to Retail -> Headquarters setup -> Azure Active Directory applications. Or, just type Azure Active Directory applications in the Search Box in AX which can be found near top right corner and you will locate the UI regadless of your SKU.
