Hello @Prasanna Gudaparti , Thanks for using Microsoft Q&A Platform.
To create a support request in Azure, you must have the appropriate access to a subscription. This means you must have the Owner, Contributor, or Support Request Contributor, or a custom role with Microsoft.Support/* at the subscription level. If you don't have the required permissions, you won't be able to create a support request.
Please follow this documentation to create an Azure support request: https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request
Additionally, here are the support plans, for specific support yes, we need to purchase please go through this documentation: https://azure.microsoft.com/en-us/support/plans/
Please do not share the Azure subscription ID or other sensitive information here. I hope you understand.
Regards,
Vasavi
