Temp tables with a XML target

Question

Hi guys,
I posted a question last week about sorting an element while generating an XML file but didn't get any answers maybe my question wasn't clear. Here is another problem with the XML technology...which begins to upset me because I don't have any idea to solve it.
To sum up, my XML schema named QST is stored in the memory engine and not in an external base. I have a package with a set of interfaces one for each XML table and a final CreateXMLFile treatment.
Most of the time, my package runs well but sometimes I get this error in one interface:
Step 1:
+     Query+
+     drop table QST.C$_0QUESTION+
+     Warning message:+
+     0 : null : java.sql.SQLException: Table not found: QST_C$_0QUESTION in statement [drop table QST_C$_0QUESTION]+
Step 2:
+     Query:+
+     create table QST.C$_0QUESTION ( .... )+
+     Error message:+
+     0 : null : java.sql.SQLException: The table C$_0QUESTION already exists in the schema QST+
This problem can occur at the creation of any working table C$, I$, E$ or SNP_CHECK_TAB.
So it seems it is linked with the in build memory but what gets me mad is that I can't get the pattern to reproduce the error.
Any idea would be greatly appreciated and I really hope this post will be more "inspiring" than my first one :D
Thanks,
Thierry

Hi Rathish,
thanks a lot for the time you spend to help me.
As you say, the table is coming with an underscore in the error message... it's strange but I think it's just a small bug when ODI generates the error message. I say so because the package runs with success most of the time and the XML I get is well built. But maybe not, so to answer your questions.
The KM I use is the original IKM SQL Incremental Update as it is indicated in the ODI user guide.
So there shouldn't be any problem
Best regards,
Thierry
