why not just configure the error output to ignore failure. This way it will just out Null for non-numeric data.

The string's value probably is not a number. IE, "abc" cannot be converted to an Int4.

Also, it's a good idea in SSIS to have one or more "Bad Row" output files, that you use in the DataFlow to divert such records to. Makes it a lot easier to figure out what's wrong.

If the column is varchar and it has all numeric values than it can be converted to Integer by using data conversion but if it has single non numeric value than you will get error.

I faced the same issue and I solved it by :

converting the column which has having issue at source side to : DT_WSTR
and in the staging the colum data type I kept as nvarchar

It resolved the issue.

Thanks.
