Unable to fetch data from stream analytics job enabled with managed identity getting input from event hub (in other subscription).

In "Subscription A", i have a Stream Analytics Job enabled with managed identity. This job is getting its input from an event hub which is in another "Subscription B". I have assigned appropriate roles in event hub for the job. After i start the job, I ma getting an error as below. However if the job is not enabled with managed identity, getting input from same event hub (in another sub), job executes perfectly.

Error message.
"We cannot locate the resource for the selected input. Please make sure its subscription has been selected in the global subscription filter."

    Hello @Abhijit Jadhav ,

    Welcome to the Microsoft Q&A platform.

    UPDATE: You could try to make sure the subscription (which your Event Hub resides in) has been selected in the global subscription filter.

    Navigating to Subscription Page in the portal and check whether the subscription is selected with global subscription filter. If not, select it in the right box.

    This is a known limitation, when using managed identities to access Event Hub from an Azure Stream Analytics job

    During preview, sampling input from Event Hubs on Azure portal will not work when using Managed Identity authentication mode.

    Reference: Use managed identities to access Event Hub from an Azure Stream Analytics job (Preview).

    Hope this helps. Do let us know if you any further queries.
