Hello everybody,
I just wanted to update the discussion with the current status so that it is helpful for somebody searching for the same problem.
I contacted sap support, they confirmed that the issue should be solved with CR 2013 SAP 07. However, they are able to reproduce this issue. Currently I'm waiting for the SAP support contacting the developer team to ask why this issue hasn't been fixed in SP07.
I will update this discussion again when I have a solution.
Regards,
Marius
