Grass, you need to do a few things right so that we know what the problem is and can head into the right direction.
1. Do what Lynn said in his last reply.
2. What does the Execute Process task do??....What task is it executing?
3. Can you tell us clearly which part is causing the error?....The code you posted or the SSIS package?
We won't be able to move forward without the DDL and the sample data.
