This process is available to the system administrator so he can easily manage the EDI Formats (EDIFact).
Such a format can be imported or exported. Since these represent a standard, you can easily take a format for a certain document type or instance, made available by a business partner, and apply it without having to waste time defining it.
Furthermore, it is recommended you save the stable formats that you use, so as to:
not lose them or accidentally alter them (be careful with the roles to which you grant access to these definitions!);
make modifications when deciding to change the version as according to the EDIFact.
