It would be great if Request Definitions could support global picklist value sets. This is a feature of Salesforce that allows you to maintain a picklist or mutli-picklist in one location.
In Remedyforce, if we create a picklist field, we should have the option to choose "Global Picklist" and select the value set we have setup in Salesforce. This would be a highly efficient method to allow many service requests to offer the same options without being maintained separately in each form. . The workaround currently would be to use Lookups to a custom object. However, the lookup behavior is not as user friendly.
