Environment : BI 4.1 SP3 and BW 7.4 SP3
We are doing a pilot for converting all .Unv based reports. Below are observations when pointing .Unv to BICS
|some of the objects are pointed to wrong objects||Remap again the objects which are pointed incorrectly|
|If constant filters applied on a detail object in the filters pane ,
then we can’t map this object to any of the object.
|Remove all the filters from filters pane before change ,
place filters after source change
|Prompt screen loading and Prompt LOV’s fetching
is slow compared to .Unv
|Cascading Filters : with UNV we created different levels of hierarchies
for drill down and for filters report specifically.
|For drill down we can have BW hierarchy
(Lot of development effort in BW ,and could not be report specific) .
|Cascading Filters is limitation , idea has been posted BI 4.0 – WebI on BEX (BICS) –
Make report Drill Filters capable of handling linked / cascading relationship between SAP ….
|Most of the BEx variable texts(prompt description )
are customized in Universes .
|we may need to change the Variable texts in BW .
This will be difficult when we have reports with 2 or more queries .
Variable text should be same for all queries.
|We can’t have measure objects in the query filters pane.||Apply filters ib Bex/in the Webi report|
|Web Intelligence Query Panel – not possible to use “OR” operator
when creating Query Filters on BICS BEX source
|please refer : SAP Note 1687933|
1.we have seen ~5% of performance improvement.
2.In some universes we are converted Detail Object Keys (Attributes of dimensions . Ex :Customer Key /Material Key) into dimensions for merging (we can’t do merge on details objects in 3.x ) . In 4.1 we can directly merge Detail objects.
Hope this helps …
