Manual Deployment Task Are Not Created in the Deployment Record
When creating a Deployment record from a promotion, you may have noticed that the deployment tasks in the user stories are not created as manual task steps in the deployment. This is the expected behavior if the deployment has been created with the CheckOnly checkbox enabled.
Manual tasks are not added to the Deployment record for validation deployments. Once the deployment is validated, you will have to create a new deployment from the Promotion record with the CheckOnly checkbox not enabled in order for the manual tasks to be created.
