Execute one scenario parallel

Question

Hi,
I want to execute tha same Scenario with two diferents source files (w/ async session) in the same time.
The data server is configured to receive the file name (with ODI Variables). When I execute the scenario just a once, that is fine.
but when I try to execute the same scenario asynchronously, An error is raised with the following description "name is already used by an existing object".
This error is raising in create work table step, It is obviosly the LKM is trying to create the work table with the same name in this two sessions.
Does any one kwon how to solve this?
Thanks

Is there a specific reason, you are using FILE to SQL.
What is your SQL database where you are trying to load ? If it is Oracle, then for large volumes of data, LKM using SQLLDR is much better.
Anyways, as Nithesh suggested, duplicate the KM and modify the step 11 "Create Work table" and mark it for Ignoring Errors.
And you will also need to remove the step of Drop Work Table.
However, I think that the truncate table command will have a side effect that if file1 is yet being loaded and file2 has finished loading, then the Truncate table for file2 will also wipe out the remaining records loaded for file1.
Since, each record is being loaded one by one and not as a set, this problem may arise.
There is another approach that may be used, assuming that the SQL database is Oracle. Similar constructs may exist in other RDBMS like SQL Server, but I donot know them well enough.
In Oracle, You can create the temporary table as a "Global Temporary Table"
And replace the step 31 "Drop Work Table" of LKM with "Delete * from table".
So, this will wipe out the records only for the session of file1 and not file2.
Hope this helps.
