>One thing that has been frustrating, MS did a great job in distancing the user from being the owner of objects (tables, procedures, etc.), as that caused problems when a person would leave. In creating SSIS packages, though, the package is created in my own personal home directory structure. I have moved it to be under the SQL structure, but when I go to schedule the package (in the general tab of the new job step window), it gives me an invalid path error. It is also a clustered server, so the path may not be visible to both servers on the cluster (although the data and log files are there).
