Document mapping
In document mapping a From <document name> column is shown, for example “From Sync.UserDetails”. The column name changes whenever the document name changes. The same is valid for the To <document name> column. The column represents the schema of the patch document. It is used to select attributes as source values. The “To document” represents the schema of the input and output document. Note that it is the same document type. It is used to select target location for source values.
