Have you ever been faced with the SSIS error “Row yielded no match during lookup”? If so, this blog is for you!
A customer of ours recently faced the same issue in one of their SSIS packages and asked us to investigate this for them.

So why was SSIS reporting an error and ultimately causing the package to fail?
Read on to learn why. For bragging rights (and a demonstration of how much SSIS pain I’ve suffered through the years), I got it in one.
