API Spec version

2025-03-01

Describe the bug

We were regularly using POST https://management.azure.com/{scope}/providers/Microsoft.CostManagement/query?api-version=2019-01-01 on subscriptions scope to get cost details for several years without any issues.
After 25th of June this year API calls started failing with Error message:
BadRequest","message":"Invalid query definition: Invalid dataset grouping: 'ConsumedService'

We tried to bump API version to 2025-03-01 but behavior is the same.

Expected behavior

Call POST https://management.azure.com/{scope}/providers/Microsoft.CostManagement/query?api-version=2025-03-01 on subscriptions scope with grouping on ConsumedService succeeded

Actual behavior

Call POST https://management.azure.com/{scope}/providers/Microsoft.CostManagement/query?api-version=2025-03-01 on subscriptions scope with grouping on ConsumedService fails with:

Error message:
BadRequest","message":"Invalid query definition: Invalid dataset grouping: 'ConsumedService'; valid values:

'ResourceGroup','ResourceGroupName','ResourceType','ResourceId','ResourceLocation','SubscriptionId','SubscriptionName','MeterCategory','MeterSubcategory','Meter','ServiceFamily','UnitOfMeasure','PartNumber','BillingAccountName','BillingProfileId','BillingProfileName','InvoiceSection','InvoiceSectionId','InvoiceSectionName','Product','ResourceGuid','ChargeType','ServiceName','ProductOrderId','ProductOrderName','PublisherType','ReservationId','ReservationName','Frequency','InvoiceId','PricingModel','CostAllocationRuleName','MarkupRuleName','BillingMonth','Provider','BenefitId','BenefitName','CustomerTenantId','CustomerTenantDomainName','ResellerMPNId','PartnerEarnedCreditApplied','CustomerName','PartnerName'
