I'm sorry but I will have to point a few things out now:
1) Please post in English on SCN
2) If your query is not answered completely, why did you mark an answer as correct?
3) You second query does not seem in any way related to your first query. You should post a separate discussion for this.
4) You cannot expect to give a message number and expect SCN users to search the message text and the scenario triggering it. Answering questions on SCN is not a profession for people. Most people answering on SCN are pretty busy and will not have time to search for the text of your error message.
Now, if you can explain the scenario and the error message, someone will help you
