Hello Kakisaisudharshani,
Currently Azure cost management connector in power BI only supported for direct MCA customers and Enterprise Agreement customers. It is not yet supported for Pay-as-you-go or indirect MCA customer.
When it comes to enterprise agreement customer type enrollment number is mandatory and added as billingaccountsId and billingprofileId in scope identifier step as shown below.
/providers/Microsoft.Billing/billingAccounts/{billingAccountId}/billingProfiles/{billingProfileId}
Plesae note user will be prompted to login, where user must login using their EA admin credentials. RI data will be available using this feature. Please find the below document for available data through this connector.
