MS SSIS 2005

The component failed because truncation occurred, and the truncation row disposition on "output column " specifies failure on truncation. A truncation error occurred on the specified object of the specified component.

common error messages when dealing with SSIS. and you google alot to know the answer. some people advise to user derived columns!

but the problem is when initiating the data source itself.

So the answer is pretty simple:

for the field that produce this error, on the output field for this field make it not fail the componenet but rather ignor this error.
