Hi Pavel
Right. The messages are not there in RSRT. As I haven't got the error, I wouldn't be sure that it wont appear in your RSRT. Go to RSRT, enter your query name and choose messages button. You will have lot of other buttons now(sort of categories). Make sure you check all the categories carefully.
PS: The thread was created in 2011 and its difficult to track the changes that has been made in these 4 years.
So if your problem still exists, wait for sometime if someone else replies or raise it with SAP please.
Regards
Karthik
