I had another problem with another Job. I had to update the SSIS package in order to FTP data from different Vendor. And tested the package. It works fine and the data was processed and saved as it should. After that I saved the Package and add updated the Job by re-saving the package data. But it seems to me that the Job somehow still is hooked up to old package.
I have SQL 2008 R2, SSMS 2005 and SSIS Packages are created in MS Visual Studio 2005. Any suggestions?
