Join Stage behaving goofy

[ray.wurlod]

How are the data (a) partitioned and (b) sorted on the inputs to the join stage? Have you made sure, in input link execution order, that the stream input is marked as Left? What style of join are you implementing?

Thanks Ray for your quick responce,

Both the source links are partitioned on KEY and sorted on same before joining. The join type is left outter join ( ABC is Left).
Link execution order ABC is 1st and DEF is second.

Thanks

Good. Now check the Mapping tab (on the Output link) to see from which input each of the output columns is derived. Remember that any column derived from the Right input must be nullable, because a left outer join can return NULL from the Right input.

Yes, in my mapping all the columns mapped to the output from right link are nullable.
I'm not getting why my join is behaving goofy.

Thanks

And I, blindfolded as it were (I can't see your job) am trying to undertake a systematic diagnostic process. Apart from rushing to post on DSXchange, what diagnostic measures have you taken?
