Hello Thorsten,
Just to check: I'm not sure what catalog version you use (is this exported with each diagpack?), but did it include the constraints on tables PERSON and ACCOUNTTRANSACTION? As I told you in a previous post, we could not reproduce the error when these constraints were missing.
We can of course reproduce the bug with another kernel with more traces if you want to. That is really no problem for us.
Regarding the data, this might indeed not be possible ... but I can check anyway.
Best regards,
Christophe
