When creating import files, consider the structure of the files. Especially when defining relationships, multiple files may be used to define one-to- many relationships. Business elements can be comprised of members and subscribers. Separate files may exist for these files or may exist for all of the different business elements.
The import files define business elements and service data, related infrastructure, and lists of related elements. The lists of related elements can be very useful when constructing relationships among large groups of elements, subscribers, or applications.
