Billing Forecast not working in Subscription Billing

[ankit__123__]

Hi

There is requirement to GET upcoming bills from subscription billing system.
I am using the Billing Forecast functionality to GET the upcoming bills.
I have done the required configurations in Subscription Billing

>I have configured a billing forecast type and specified the horizon in Business Configuration.

>I have assigned the billing forecast type to the subscription profile and used that in the subscription.

Next I try to GET the upcoming bills in postman using the request URL:
https://eu10.revenue.cloud.sap/api/billing-forecast/v1/forecasts/61D5A619-CABB-4927-B504-355B6FCBD3D...

In response it gives forbidden error.

How do I get it to work, please advice

Follow chapter 3.4 (Create Service Instance) of the SAP Subscription Billing guide for BTP configuration set-up.
The end of the chapter also refers to the update options.

Hi Ankit,

just to verify the "easy options for solving this":
Did you make sure, the API credentials you're using grant access to scope

Full list of API scopes:
