Displaying the Interface Structure 
Use
You use this function to display the structure of the transfer file. The interface structure gives a technical description of the transfer file and displays the structures that may be used and their sequence. The interface structure also provides you with the detailed information that you require when converting your legacy data.

You can also display the interface structure without using the Data Transfer Workbench by running program RSXDAEXP. This gives you the option to display the structure without the field information. This makes it easier to see the sequence of the structures.
