Enterprise Configuration Settings are the settings of the customized Serna view (see Serna View Customization) and XML metadata files (e.g. xml catalogs, stylesheets, schemas - of interest mostly to developers) which can be applied to any Serna installation in an enterprise.
Suppose someone has created buttons on the toolbar and saved the view as template-specific or no-template view. If they create a package with the view files, these settings can be given out to other people in the enterprise and can be be applied to any Serna installation.
Information about how to create a package with Enterprise Configuration Settings is available in How to Manage ECS Package .
For instructions on how to apply the already created package with ECS to any Serna installation in a company, see Applying Enterprise Configuration Settings.
