Query stripping is feature
in WebI that is available on XI 3.1 SP3 and BI 4.0. Basically it does optimize a
set of data fetch from underlying WebI’s document source. If this feature is
on; only data (in WebI terminology: measures and dimensions) that is used in WebI
document output is fetched. This reduces traffic between presentation level (WebI)
and source of your data.
How to switch it on: it is
possible to be enables in two levels: 1. Query level – under Query Properties
there is flag enable query stripping 2. Document level – flag query stripping
on Document Properties tab. You need to enable both levels otherwise query won’t
be stripped.
Notice that query
stripping feature is only available for OLAP sources (e.g. BEx queries,
Universes).
However there are few
constrains while using stripping: It may happed that you will get a tag #Refresh
displayed instead of data. This bug is supposed to be solved in BOW Fix Pack
4.2 see note 1585615.
If you running into this problem even you have patched your system you need to switch
off this feature. Also it may happen that your WebI variables won’t work and
the tag #Refresh will be displayed instead. In that case also switch it off.
