ah, now I am getting close. So the IDENTIFIER attribute of a SPEC-OBJECT should never change, while the requirement develops over several roundtrips – OK.
The foreignid should be human readable and therefore also cannot be the place for my “real” id. And the ALTERNATIVE-ID is not meant for this also – and shouldn’t be changed.
But if I have no possibility to transport the real id through the roundtrip iteration, then I would need to store a mapping between the IDENTIFIER (which stays the same through the whole conversation) and the real id for each outgoing Customer Request.
Wouldn’t it be much better, if I could transport the real id through the reqIF roundtrip?
Thanks for you reply btw 🙂
