When you create a publishable document type from a Broker document type or synchronize a publishable document type by pulling a Broker document type from the Broker, you must decide if you want to overwrite any existing elements associated with the Broker document type.

For example, suppose that you are creating a publishable document type from a Broker document type that was created on another Integration Server. The Broker document type might reference elements such as an IS schema or other IS document types. However, the Integration Server on which you are creating the publishable document type might already contain elements with the referenced names. Before you overwrite the existing elements, you need to know if there are any differences between the existing elements and those being imported from the Broker. If there are differences, you need to understand what they are and how importing them will affect any elements that use them, such as services, IS document types, or triggers.

When you create a new document type from a Broker document type or when you synchronize document types, you can use the Overwrite existing elements when importing referenced elements check box to indicate whether existing elements should be overwritten by imported elements of the same name.
