For each level in the organization hierarchy, you need to set the relationship between metadata on metaform and database values. The basic scenario in previous sections described how to merge data at the document level. However, it often happens you need to define the global merge settings to be associated with any document under specific files. Suppose, you have a number of documents assigned to different document types and you need to apply a new merge setting to all these documents.
