Dear Experts,
We have a requirement where a report only has characteristics and no key figures and this report is transactional report(transaction level Detailed).
My question is that as this is a detailed report with no key figures, does loading this data to cube will be of any use in terms of query performance or can I report directly on DSO as performance is achieved on cube as it aggregates or compress the key figures but we don't have any key figs here.
So in this case does it make any sense to load the data to cube from DSO to improve query performance as I don't want to utilize additional background process to drop the cube data and do a full load daily if there is no improvement in performance.
Please let me know if I didn't explain my query well.
Many thanks.

Dear Experts,
Many thanks for your valuable inputs.
So I think I am very much clear on the modeling part i.e. to go with a DSO.
Still a doubt which remains is the query performance........In scenarios like this...Even if I create a dummy key figure and go ahead with cube....does cube has any advantage in terms of query run time than DSO ? I mean I heard people saying Cube has index and so query performance would be much better than DSO......is this true ? What if I create secondary index on DSO ....still cube will be better in terms of performance or ???

HI,
with out key figures we can not create the cube but we can create the DSO with out key figure values.
DSO have the operational reporting.
it was two dimensional model.
DSO level have detail level data.
'
CUBE
it was multi dimension model.
it will store the aggregated data.
for your point don't have any key figure values, DSO will create with out any key figure values.
but CUBE we can't create the with out key figure. required one key figure mandatory.
if don't have any key figure values go with the DSO reporting.
select the DSO setting - SID generation upon activation.
Thanks,

Hi John,
No sense.
BW is only for analytical information, and you only need create a Query without keyfigures.
I recommend use your ODS to create this report.

with out key figures
how can you create aggregates and compression on info cube ?
Is not possible with out key figure created data loading into info cube
aggregates property summarized key figures based on same characteristic values.
compression property reduced the number of records by combining records with same key ,Requst id deleted
data records moves from f table to e table

Hi John,
Have you create cube without key figure ?
If create report based on CHAR and KEY figure i think key figure display properties will be hide in reporting.
either no data loading CUBE amd DSO,
Please check data available in PSA level in key figure,
There is no diffrent reports used based on CUBE or DSO.
Thanks,

Hi John,
I think keeping the data in DSO is the best way in your case as far as I understood. Because you have no keyfigure. addition to this, infocube is set of relational tables as well. So you will increase complexity.
