is caught in rsc.makeData. You can raise this at any place during source processing to skip the rest of this source but the go on.

You should pass something descriptive as message so upstream can potentially report something is skipped and why.

Note: in a rowmaker, you probably usually want to raise IgnoreThisRow instead; it's rare that you want to ignore the rest of a source just because you don't like a row.
