What you need to know
A template can fail SKU validation before a deployment starts, leaving evidence outside the deployment-history view.
Potentially affected
Azure ARM or Bicep deployments rejected because a requested SKU is unavailable for the selected subscription, location or zone.
DSE recommendation
Capture the Activity Log validation error and exact requested SKU scope before changing the deployment.
Source facts
Microsoft documents that an ARM or Bicep deployment can fail SKU validation before execution begins. In that case, InvalidTemplateDeployment appears with an error message, no deployment history is created, and the error is available in the portal’s Activity Log.
SKU availability must be checked for the subscription’s selected location or zone. The documented CLI availability listing hides restricted SKUs by default; its –all option includes those restrictions in the review. Microsoft Learn.
Applicability
Record the subscription, region, zone, requested resource SKU and original validation response. Keep a predeployment validation failure distinct from a resource that began provisioning and failed later.
DSE recommendation
DSE recommends preserving the Activity Log evidence before retrying with different settings. Review the actual restriction information and the workload’s placement requirements together. Do not choose an arbitrary region or smaller size merely to make validation pass. If the required placement has no suitable available SKU, route the documented requirement through the appropriate support or architecture decision.
Verification
Compare the planned SKU and placement with the current subscription-specific listing, including restrictions. After an approved adjustment, rerun validation and confirm whether deployment actually starts. Preserve both the original rejection and the new outcome. A missing deployment-history entry should not be recorded as proof that no request was attempted, and a passed validation should not replace subsequent workload verification.
