SSIS: Error in the package when the data in the flat file source is modified


Hi All,

I have a package which loads data from a flat file source to an OLEDB destination, which is executed successfully and data is loaded perfectly.

But later when the data in the flat file source is modified i.e. if an extra column gets added to the text file, the package is throwing an error because it is unable to detect the extra added column.

How can i avoid this error??? I need my package to execute successfully ignoring the changes(added columns) happened in the flat file source.

Please provide me wth your suggestions and solutions....

Thanks in Advance!!

Error connecting using SPSite

Has anyone seen this error message?

The Web application at http://ecnet/Pages/Default.aspx could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Any thoughts? I can't seem to connect to the Server like I used to in SharePoint 2003.
