Answer / chakravarthy kanishka
Look doesnt requires common key coloumn, then why we need key,
if we go for sequential file as a look up, and squential file have huge data,then it hits the performance,again you need to apply the performance techniques to the sequential file while reading the data,so better to avoid sequential file as a reference to look up.
its my guess...
please let me know if wrong.
thanks
