The No transformation option is used when Babelway interface is used to transfer an unchanged message from one gateway to another.
If you are only transfering messages that do not require transformation from a gateway to another, for example from a mail server to an FTP server, you should use the "No transformation" transformation type.
When specifying this transformation for the first time or when changing transformation type, choose a " No transformation " from "Create a new transformation of type" drop down menu.
If the formats of Message IN and OUT are not the same, using "No transformation" may return unexpected results or empty output messages.
Usually, this setting is used in combination with Message IN and OUT "Not Defined" formats in a channel that simply transfers an unchanged or unprocessed message from one gateway to another.
