If you send a Tata Nano from India to Germany, then it is still a Tata Nano when it arrives, and not a Mercedes. There may be some smaller modifications to get a registration in Germany, but this does not really change the basic attributes.
Quite similar it is with sending materials by ALE, it arrives like it was sent, you are able to exchange some values, e.g. exchanging sales org AAAA to BBBB , but you are usually not adding extra segments to this Idoc to have finally 3 sales segments instead of one.
