Which on is better-ODS/INFOCUBE for reporting

Hello expert's
1.I want to know which one ODS or INFOCUBES are better (technically/functionally) for reporting purpose in BW.if some one is having any comparisons on ODS/INFOCUBE then plz pass on to me.
2.Are Z tables reliable in case of data updation and fetching when we create ODS/INFOCUBE.
3.HOW RELIABLE THE "Z"(*TABLES/REPORTS) are in SAP-BW/R/3-ABAP.

Hi Gaurav,
1.The choice of ODS or cube for reporting depends upon your requirements. It depends upon several factors like the details in which you want to see the reports, the amount of data you will be looking at etc. Since ODS is a flat structure (transparent table), you can not store large amounts of data. If you want to see some reports which contains data for several years (huge), you are better off running a report on a cube. Otherwise, reporting on ODS is ok. It all depends on your requirement.
2. You definitely can extract data from Z tables in R/3. Again the type of extraction depends upon the design of the R/3 table. You should not have any problem in extracting the data from R/3 Z tables into an ODS or cube.
3. When you say Z tables/reports, they are totally custom made. So, if they are used regularly in R/3, i think they must be reliable. If they are not reliable, they would not use them in the production server.
Hope this helps.
Thanks and Regards

1.Cubes are optimized for reporting..due to star schema structure.Use cubes for reporting aggregated data to be accessed by large number of users.
ODS are for detailed level reporting.ODS structure is like flat DB table.
usually drilldown is setup from cube report to the ODS report.
2.Are u referring to custom ODS and cubes..then they have the Z tables internally..reliability depends on ur design.But always try to use BC content,else copy BC content and change/enhance it.else if no BC content found then create Z-content directly.
3.Again,depends on the design.But always using BC content is suggested.

Standard or custom procurment ODS, InfoCube for BI-7.0 implementation

hai
we are implementing BI-7.0 for first time to the clien for <b>procurement</b> .
so we need to extract the data from EKKO,EKPO and some other procurment tables.
so can if i use 2LIS_02_HDR, 2LIS_02_ITM . can i use the standard 'purchasing' ods and infocube.
If i want to use standard purchasing ods,infocube then they are in BW 3.0 . But we want in BI 7.0.
So what can i do for this one. Otherwise can i use the custom ods and InfoCube for procurement secario.
pls suggestion mw wht i have to do ..
i will assing the points
kumar

Hi.
I thought you asked me if it was OK to use the standard DSO and Cube from rel 3.0 although you are on 7.0?
You should use that DSO and cube, that's what I meant. You will not have any problems with using them although you are on a 7.0 system.
Hope I'm cear, or have I misunderstood anything?
Kind regards

Unable to consolidate data from two DSOs into an InfoCube for reporting.

Hello Experts
I am working on BW 7.0 to create BEx Report as below:
This report will have data coming from two different sources, some data from COPA DSO [such as Customer Number, Product Hierarchy1, Product Hierarchy2, Product Hierarchy3, Product Hierarchy4. Product Hierarchy5, Product Hierarchy6 and a few other Key Figures] and the rest [such as Product Hierarchy, Reference Document, Condition Type (both Active & Inactive), Condition Value and a few other Key Figures] from another DSO (ZSD_DS18) which is a copy of the BCT DSO (0SD_O06). I've chosen this DSO because this is the BCT DSO which is used to store data from a Standard Extractor 2LIS_13_VDKON.
Below are the screenshots of these 2 DSOs:
I have successfully extracted the data from 2LIS_13_VDKON (includes PROD_HIER but not Customer Number) and loaded into a DSO (ZSD_D17).
All the testing is done using only one Sales Document No (VBELN).
First test that I tried is.. to create an Infocube and loaded data from ZCOPA_01 and ZSD_DS18 and when the LISTCUBE was run on this InfoCube, the data is coming up in two different lines which is not very meaningful. Screenshot below:
Therefore, I have created another DSO (ZSD_DS17) to Consolidate the data from ZCOPA_01 & ZSD_DS18 establishing mappings between some of common Chars such as below:
ZCOPA_01                    ZSD_DS18
0REFER_DOC <->        0BILL_NUM
0REFER_ITM    <->        0BILL_ITEM
0ME_ORDER    <->        0DOC_NUMBER
0ME_ITEM        <->        0S_ORD_ITEM
51 records are loaded from ZSD_DS18 into ZSD_DS17 and 4 records are loaded from ZCOPA_01 into ZSD_DS17 for a particular Sales Document Number.
When I am using a Write-Optimized DSO, data is coming in just 1 line but it is showing only 4 lines which is aggregated which is as expected since W/O DSO aggregates the data. However, when I use Standard DSO, the data is again splitting up into many lines.
Is there something that I am missing in here while designing the Data Model or does this call for some ABAP being done, if so, where or should I have to talk to the Functional Lead and then Enhance the Standard Extractor, and even if I do that, I would still have to bring in those Key Figures from ZCOPA_01 for my reporting?
Thank you very much in advance and your help is appreciated.
Thanks,
Chandu

in your (current) InfoCube setup, you could work with "constant selection" on the key figures
for the COPA key figures, you'll need to add product hierarchy to the key figures with a selection of # and constant selection flagged
for the SD key figures, you'll have to do the same for customer & the product hierarchy levels (instead of product hierarchy)

Please tell any one which toll generally we are using for reports

hi evertybody, please give me this information regarding report generation, and can tell me the brief information reg segment, document splitting
thanking you.

Hi
I think toll means total. in reporting you can have total at any level . The sum function allows you to select the block and you can set total there.
Segment is a part of company code for which separate balance sheet has to be prepared as per US Gaap, IFRS etc. This is supported by SAP by the document splitting function. You has to define scenario update for both profit center and segment, as segment is derived from the profit center master. All transactions are split according to the document splitting rule . Also you have to activate zero balancing in document splitting , so that balance sheet for segment can be generated.
Thanks

If it were me, I'd save the $60 and get the 2.3GHz one. Its only 4% slower in the specs and will be hardly noticeable in use. The only advantage to the newer one is the Haswell processor which might (note that it is only a might) give a little better battery life with a trade-off of 15% in raw performance.

Which on is better for reporting ODS/INFOCUBES

Hello expert's
1.I want to know which one ODS or INFOCUBES are better (technically/functionally) for reporting purpose in BW.if some one is having any comparisons on ODS/INFOCUBE then plz pass on to me.
2.Are Z tables reliable in case of data updation and fetching when we create ODS/INFOCUBE.
3.HOW RELIABLE THE "Z"(*TABLES/REPORTS) are in SAP-BW/R/3-ABAP.

Gaurav,
1. Cubes are definitely better for repiorting if cubes are used as cubes which would mean :
a. Cubes should have aggregated data and nto line item data
b. Cubes should not be used to store master data
c. Cubes with large amounts of data are regularly compressed and statistics and relevant indexes maintained
d. You can check the infocube design by using RS_INFOCUBE_DESIGNS ( I do not remember the program name properly )
ODs on the other hand :
1. Should be used for storing detail ( line item ) level data
They need not always be used for reporting
2.As for your other questions , please define reliabilty , there are many definitions for reliability and if you can elaborate on reliability it would make it easier for a directed reply.

Which IDE is better Jdev or Eclipse for BPEL

Hi All,
Which Tool is better to use for BPEL - Eclipse or Jdeveloper.
Thanking You,
Rakesh.

for j2ee netbeans is best. if u use ecplise(wtp) it create only web.xml.Maybe you did something wrong :)
compare with ecplise netbeans is best it have
1) xml gui tool, verification and validation
2) no need to create web.xml
3) debug also easy and user friendly.Eclipse also offers this.
After all, just install them both and try them both out. If you want my opinion: Eclipse Europa for Java EE or IntelliJ IDEA.

Function Modules for Report Display of Nodes/Hierarchys in BW/SEM?

Has anyone done this? have any suggestions?
Thanks.

Hi Tom,
Typically the standard solution within SEM-BCS is to use a virtual InfoCube for reporting on transactional data.
The virtual InfoCube has been assigned a service, namely the SAP delivered function module RSSEM_CONSOLIDATION_INFOPROV, which applies the necessary SEM-BCS logic such as hierarchy and edge information to the data coming from the transactional cube.
Let me know if this helpful or you need more help.

How connect to our apex server for customer on internet for reports

We are created a report for customer and they can anonymous log on their report.
On example this link;
http://server.ourdomainname.net:8080/apex/f?p=101:1:4026431692309114
But all customer log on same link and our database performans so bad when the a lot of customer log on same link
I think this is season and wrong url link problem...
What should we do for this? And which method to use create link for report log on the internet?
Thanks.

Anton,
Now I do not get it...As I point in my thread (here is once more citate from thread):
<i>
I solve my problem with this
http://server.ourdomainname.net:8080/apex/f?p=101:1:4026431692309114
instead of
http://server.ourdomainname.net:8080/apex/f?p=101:1
</i>
is differencing in only session declaration. Many users cannot reuse the same session regardless it is public app or authenticate...they all have different session_id.
So, bad performance can occur (on database side) with more query against database and (on Apache side) some session problems or....-look in log files to get a picture.
Otherwise it is not easy to help
P.S
Place in sqlplus pure report query. Analyze it and see the if SQL tune actions are needed....outside apex and apache environment. Then you have picture where the problem reside...
P.S.
Do not use "page checksum" feature (regardless authentification exist or not).
Hope this helps

Better to go for the new iMac 24" 2.66GHz or the old iMac 24" 2.8GHz?

The old one's at $1199 in refurb
The new one's at about $1340 after an education discount
I guess the new one for the extra $140 or so will hold its resale value better - but is it a better computer and worth the extra $$$s?
Also I don't think the question's really been answered - are the processors different in the new iMacs - have they been physically updated in any way?
Which is it better to go for? Just want to run Logic Studio 8 on it.
Thanks.

Well for your $140 difference you get twice the RAM, twice the hard drive space, and a better/faster graphics chip set.
I don't know if the processors are materially different other than speed and the difference is not significant, so I wouldn't stress to much over the 2.66 vs. 2.8 speed ratings since for most processes it probably won't make a difference, but the 2.66 one will probably seems a bit faster since it has twice the RAM. Also, while super expensive right now, the RAM on the newer ones allow you to upgrade to 8gigs of RAM (once those DDR3 SODIMM RAM prices drop). Are the old models limited to 4MB max?
For only $140 difference, I would go with the new model since the upgrades you get more than cover that. I would only consider the older refurbs if you were picking between two models with a much larger price difference.

Which is much better for me, MacBook Pro 13" Retina Display or MacBook Air 13"?

Hi! I'm a High School Student, and I really need help in choosing the right MacBook. So which is which?
I'm really confused in choosing which MacBook suites. I have been researching about the specs of each MacBooks; some websites say "MacBook Pro is much better" while the others "MacBook Air is better than the Pro". I'm totally confused! And PLEASE HELP ME!
Here is what I need for a laptop:
*I will use it for Editing Videos and Photos
*sTORAGE for my Documents! (Word, Excel, Powerpoint, Adobe)
*PRINTING documents and stuff
*Great Quality for Movies, Videos, and Music
*GAMES!!! (Assasin's Creed, Sims, etc.)
*Other Apllications
*Storage for my stuff
*Best performance for INTERNET, SOCIAL SITES, & ENTERTAINMENT
*Handy and Easy to use
*Lightweight ('cause I have to bring it to school for reports and I have to bring i to to different places for conventions or seminars)
*STORAGE for my Photographs, Music, Movies (edited and downloaded)
*Long Lasting Batteries
*FAST and QUICK
I'm really confused, which shal I choose: MacBook Pro because it has the best performance or MacBook Air because it is very convenient.
I WOULD REALLY APPRECIATE IF YOU HELP ME.
Message was edited by: Samkeyness

Unfortunately, you mentioned "GAMES!!!" - no Mac notebook is a good gaming machine (sad but true). For everything else, however, I would recommend a MacBook Pro (Retina or non-Retina - whichever you prefer, although my preference is for the non-Retina: it lacks the portability of the Retina but is user upgradeable whereas the Retina 13" machine is limited to 8GB of RAM, soldered onto the logic board, and a 'fixed' storage space).
I haven't looked at the specs but I'm assuming that the Retina model would be only slightly heavier than the Air. But it would out-perform the Air should you desire to try games with it.
Good luck - we get these "what shall I buy" questions all the time but, in the end, it's your decision.

Better user experience for slow reports (loading in background, progressbar

Hi
In our application, some reports take a long time till they are displayed. Therefore it would be nice, if i could provide the user with some feedback (example: progressbar). Is it possible to have this? Upon print, when a pdf file is being constructed (in web) we already have such functionality in place, is it possible to have it generally?
Mayb,e it would also be possible to have the report load the first page quickly, so the user has already something to look at, and load all the other needed data in a background thread. (i dont think it is possible, however, somebody may have an idea)
Does anybody have an idea how we could achieve a better user experience for our reports. Any help is appreciated. Thanks.
Greetings
I am using:
Crystal Reports 2008 (in Asp.net, Windows Forms)
Version .NET 3.5 (SP1)
PS: of course a very fast report would be the finest solution. However, i guess this will not be possible with our reports and the volume of data they access

Hi Daniel,
Crystal Report 2008 we have a inbuilt functionality of progress bar .If you are not getting progress bar for every report that means those reports are not taking to much time.
For more info regarding progressbar this check this link:
[https://boc.sdn.sap.com/node/8035]
Look for processingIndicatorDelay and processingIndicatorText.
If you want to improve performance of report then we need to keep in mind few thing while creating report in Crystal report designer:
Here are a few points related to performance issue .
The performance of a report is related to:
External factors:
1. The amount of time the database server takes to process the SQL query.
( Crystal Reports send the SQL query to the database, the database process it, and returns the data set to Crystal Reports. )
2. Network traffics.
3. Local computer processor speed.
( When Crystal Reports receives the data set, it generates a temp file to further filter the data when necessary, as well as to group, sort, process formulas, ... )
4. The number of records returned
( If a SQL query returns a large number of records, it will take longer to format and display than if was returning a smaller data set.)
Report design:
1. Where is the Record Selection evaluated?
Ensure your Record Selection Formula can be translated in SQL, so the data can be filter down on the server, otherwise the filtering will be done in a temp file on the local machine which will be much slower.
They have many functions that cannot be translated in SQL because they may not have a standard SQL for it.
For example, control structure like IF THEN ELSE cannot be translated into SQL. It will always be evaluated
in Crystal Reports. But if you use an IF THEN ELSE on a parameter, it will convert the result of the condition to
SQL, but as soon as uses database fileds in the conditions it will not be translated in SQL.
2. How many subreports the report contains and in section section they are located.
Minimise the number of subreports used, or avoid using subreports if possible because
subreports are reports within a report, and if you have a subreport in a details section, and the report returns 100
records, the subreport will be evaluated 100 times, so it will query the database 100 times. It is often the biggest
factor why a report takes a long time to preview.
3. How many records will be returned to the report.
Large number of records will slow down the preview of the reports. Ensure you only returns the necessary data on the report, by creating a Record Selection Formula, or basing your report off a Stored Procedure, or a Command Object that only returns the desired data set.
4. Do you use the special field "Page N of M", or "TotalPageCount"
When the special field "Page N of M" or "TotalPageCount" is used on a report, it will have to generate each page
of the report before it displays the first page, therfore it will take more time to display the first page of the report.
If you want to improve the speed of a report, remove the special field "Page N of M" or "Total Page Count" or formula that uses the function "TotalPageCount". If those aren't use when you view a report it only format the page requested. It won't format the whole report.
5. Link tables on indexed fields whenever possible.
6. Remove unused tables, unused formulas, unused running totals from the report.
7. Suppress unnecessary sections.
8. For summaries, use conditional formulas instead of running totals when possible.
9. Whenever possible, limit records through selection, not suppression.
10. Use SQL expressions to convert fields to be used in record selection instead of using formula functions.
For example, if you need to concatenate 2 fields together, instead of doing it in a formula, you can create a SQL Expression Field. It will concatenate the fields on the database server, instead of doing in Crystal Reports.
SQL Expression Fields are added to the SELECT clause of the SQL Query send to the database.
11. Using one command as the datasource can be faster if you returns only the desired data set. It can be faster if the SQL query written only return the desired data.
12. Perform grouping on server
This is only relevant if you only need to return the summary to your report but not the details. It will be faster as less data will be returned to the reports.
Hope this helps!!
Regards,
Shweta
