Re: Output port and Group by clause in SQ
Hi
No we cannot create Output ports in Source Qualifiers. They have to be linked to an input port. Yes, techinically speaking we can do a 'Group By' in Source Qualifier but I would not advice to do so. This is because it makes DB hits to group by . It is better to reall all default data and then group by using a Aggregator transformation. Cheers Manisha
