DF and SF are the most important question in Cognos
interviews. The answer shouild be given with examples. E.g.
When going for a detail filters the filters are applied on
individual data items in the report. And again we have to
keep in mind that a filter can be applied on two scnarios:
a) Before auto aggregation or after auto aggregation i.e.
before the data is brought into the cache or after the data
has been brought into the cache.
Similarly, Summary filter are applied on summary values in
the report. Here, again the above two conditions are
applicable.
