I am not able to create Azuredata factory.

Question

This error is showing while i am trying to create ADF "Resource 'adfdemoproject001' was disallowed by Azure: This policy maintains a set of best available regions where your subscription can deploy resources. The objective of this policy is to ensure that your subscription has full access to Azure services with optimal performance. Should you need additional or different regions, contact support.. (Code: RequestDisallowedByAzure, Target: adfdemoproject001):

I have used region - Asia specific(South India)

Answer 1

Hi @Nihar Ranjan

1. Check which regions are allowed

Go to:

Azure Portal → Policy → Assignments Look for a policy named:

Allowed resource deployment regions

or Allowed locations

Open it → Check the Allowed locations parameter.

These are the only regions where you can create ADF.

2. Deploy ADF in one of the allowed regions

Pick one region from the allowed list and create your Data Factory there.

3. If you need South India

You have two possibilities:

A. If you have Owner / Policy Contributor permissions

You can edit the policy:

Azure Portal → Policy → Assignments

Open Allowed resource deployment regions

Click Edit assignment

Add South India to the allowed list

Save

B. If you do NOT have permissions

You must contact:

Your subscription admin, or

Azure support (if it's a Student subscription)

Ask them to:

• Add South India to the allowed regions, or
• Create a policy exemption for your deployment Thanks.

Answer 2

Hi,

Azure for Students restricts which regions you can deploy resources to. Typically you are restricted to five different regions, and these vary for each person.

Please navigate to Azure Policy -- Authoring -- Assignments using link below:

https://portal.azure.com/#view/Microsoft_Azure_Policy/PolicyMenuBlade/~/Assignments

Click on assignment named Allowed resource deployment regions

Examine Allowed locations Parameter value for list of regions, similar to below (regions in screenshot are different than yours):

The regions shown in your Parameter value are the ones you are allowed to deploy resources to. Please try to create resources in one of these regions and let me know the results.

Please click Accept Answer and upvote if the above was helpful.

Thanks.

Answer 3

The error is caused by an Azure region restriction policy on the subscription, not by Azure Data Factory itself. The selected region, South India, isn’t currently allowed for that subscription under the policy that controls where resources can be deployed.

Use this path to verify and fix it:

1. In the Azure portal, open Policy.
2. Select Assignments.
3. Look for a policy such as Allowed locations or Allowed resource deployment regions.
4. Open the assignment and check the Parameters to see which regions are allowed.
5. Create the Data Factory in one of those allowed regions.

If the policy assignment can be edited in that environment, update it to include the required region. If the subscription is governed by organizational policy or region optimization policy, access to additional regions requires a support request in the Azure portal.

Also verify that Azure Data Factory is available in the target region before retrying.
