Symptoms
Order provisioning for a OA subscription fails. The following error is registered in the service status history for the ordered subscription:
Service Creation Failed: Parallels Operations Automation error #error_code=1000; extype_id=1000; module_id=AccountManagement; is invalid: No @ at address..
Cause
During subscription provisioning, BA sends a request to OA that includes the customer's contact information. The "No @ at address" error means that an empty or malformed email address was submitted by BA.
Resolution
Review the account administrator contact information as it is registered in BA and make sure it has a valid email address.
