System resources A system resource represents an object that is external to the work list record but is required to support system operations in the mobile app. For example, the following resources are classed as system resources for the Work Execution app: v The domain value lists that are used to change work order status and other work list record attributes. v The labor and labor craft resources for the current user that are required for labor reporting. v Labor timer settings that are active in the provider application and are required for local validation of labor transactions. System data is automatically downloaded when a user first logs into the application. If the download fails, the user cannot login. Locally stored system data is refreshed whenever the user refreshes lookup data. In the application definition, a system resource has an isSystem attribute with a value of true. Other characteristics are the same as the characteristics of the lookup resource.
