Create catalog item variables based on a CloudFormation template

After you have fully defined all parameters in a template, you can use the parameter settings to generate the variables that appear in catalog items for requesters of virtual resources. If the variable already exists, you can use this procedure to refresh the variable with the updated settings.

Before you begin

Role required: cloud_admin, aws_admin

About this task

The ServiceNow instance adds the following variable sets to each catalog item:
  • Terms and conditions
  • VM Provisioning variables (includes Assignment group, Business purpose, Lease start/end, and CMDB relationship tags, Application and Business service)
  • Cloud auto-tagging variables (includes Cost Center and Project by default)

The template contributes the Template Parameters set (unique for each template; variables that were generated from the template parameters)


  1. Navigate to Amazon AWS Cloud > Maintain Catalog Items > CloudFormation Items and select the template.
  2. Click the Refresh Variables from Parameters related link.


If the variables do not exist, the system generates them. If the variables already exist, the system refreshes them with the updated attribute settings.
