what is the difference between lookup stage reject link and
merge stage reject link in datastage Parallel jobs?
Answer Posted / shar
Well
The prime difference is
lookup reject link can collect all unmatched primary mismatched data.
Where as
in merge stage, using reject link(s) it will allow us to identify from which update datasets records got rejected.
n in addition to this as we know
lookup supports only one reject link and merge supports as many no. of updates so many no. of reject links.
thats it.
