Within the modal window, you are able to edit the attribute mapping which were initially shown during the upload process of the product data (see Attribute Mapping).
You are also able to specify a global value for the multi value separator. As a consequence all attributes with enabled multi values (see Data Attributes Table) use this separator. Note that each attribute can override the value within the Data Attribute Values modal window.
If you are using channel ids, you can also select a default channel id. This channel id is always displayed if you open the Preview or Site Integration view.
