Follow these steps to allow CloudMonitor to access and view Billing Information for Microsoft Customer Agreement customers.

:::tip
Due to a limitation with MCA billing accounts that affect Service Principals accessing cost data, we require all MCA Customers to use a B2B User with Reader Role at BillingAccount/BillingProfile scope. This limitation is a Microsoft-acknowledged issue and is currently being fixed by Microsoft.

Before proceeding, please confirm that you have already created the CloudMonitor Synapse AD B2B user. If not, please visit the following webpage [How to create the CloudMonitor Synapse AD B2B User](https://cloudmonitor.ai/docs/installing-cloudmonitor/powershell-how-create-cloudmonitor-synapse-b2b-user/) for instructions on how to do so.

To demonstrate this limitation, you can attempt to use your Service Principal and follow instructions outlined in the following webpage [Exports - Create Or Update - REST API](https://learn.microsoft.com/en-us/rest/api/cost-management/exports/create-or-update?view=rest-cost-management-2023-08-01&tabs=HTTP#code-try-0).

### Step 2
