Infocube & ODS Difference

Hi,
What is the difference between Infocube & ODS ? and in which senario they can be used ?
Regards
Praveen

Hi Praveen
ods
1 flat file formate structure
2 two dimentional
3 overwrite data functionality
4 performance is less as compared to cube
5 detailed form of data
infocube
1 star schema
2 16 dimentional
3 additive data functionality
4 performance is better as compared to ods
5 summerised form of data
Assign points if it helps
Thanks & Regards

DELETION OF SPECIFIC COLUMN DATA IN INFOCUBE&ODS(not the datarecords)

hai
I loaded the data into ODS and InfoCube.Buti want to delete the 'year = 1900&1910" from the YEAR column of the Infocube and ODS.
Is it possible to delete the specific column data from the InfoCube & ODS????
If it is possible then how can i delete the particular specific data from the specific column of InfoCube and ODS.
pls tell me
i ll assing the points
bye
rizwan

HAI Ronald
I already loaded the data into the InfoCube and ODS. But i want to delete the 'year column=1900 , 1910' only (not the corresponding datarecords).
IS it possible to delete that Year Column only from the loaded data of InfoCube .
I think , it is possible by creating a new InfoCube and transferring my InfoCube data into newly created InfoCube and writing the start routine for Update Rules in between my InfoCube & newly created InfoCube.
So do you know the ABAP/4 code for that
pls tell me
i ll assing the points

Finding the infocube/ods space

Hi,
Using transaction ST14, I have got the Space used by top 30 Infocubes, ODS etc. on quality server. The same I tried to do on production server. But it gives the message
"Field or table is initial" instead of the list of Infocubes or ODS.
But actually everything on quality and production server is same. so i am not getting the proper solution.
Can anybody tell me how can i solve this problem?

you need to schedule the job in ST14 to get the first result for top 30 objects...but take care..as it will take a lot of time and resources and your other scheduled jobs will starve...
Also you can get the size through DB02...object name and then add the size of all the tables pertaining to that object.
Hope this helps.

Designing a InfoCube / ODS

Hi
I would appreciate, if you can provide a solution to the following questions..
1) What are the main consideration while designing an Infocube / ODS ?
2) Do I need to add 0RECORDMODE InfoObject manually, while designing a ODS. ? Please give me step by step document for creating a Infocube and ODS Objects.
Please Email me at [email protected]
Thanks
Preeti

Hi,
Designing ODS/CUBE depends on u r reporting requirement.
Sometimes there is no ODS for specific functional area. If u r going to design the ODS then ou need to know the the table from where u r datasource is extracting the data. Then on the basis of that u will have to design u r ODS. If u r using 3.5 then u need to add RECORDMODE manually but in BI7.0 it will added as a default value initial.
Then u can design all the relevant dimension in the cube on the basis of logically related infoobject. U can use line item dimension if any infoobject having same data record as fact table.Here u can follow Kimbal's rule while designing the Aggregates.
If u r using BI 7.0 then u may think on BI accelerator to design and maintaing the cube.

Loading performance of the infocube & ODS ?

Hi Experts,
Do we need to turn off the aggregates on the infocubes before loading so that it will decrease the loading time or it doesn't matter at all, I mean if we have aggregates created on the infocube..Is that gonna effect in anyway to the loading of the cube ? Also please let me know few tips to increase the loading performance of a cube/ods. Some of them are
1. delete index and create index after loading.
2. run paralled processes.
3. compression of the infocube , how does the compression of an infocube decrease the loading time ?
Please throw some light on the loading performance of the cube/ods.
Thanks,

Hi Daniel,
Aggregates will not affect the data loading. Aggregates are just the views similar to InfoCube.
As you mentioned some performance tuning options while loading data:
Compression is just like archiving the InfoCube data. Once compressed, data cannot be decompressed. So need to ensure the data is correct b4 Compressing. When you compress the data, you will have some free space available, which will improve data loading performance.
Other than the above options:
1.If you have routines written at the transformation level, just check whether it is tuned properly.
2.PSA partition size: In transaction RSCUSTV6 the size of each PSA partition can be defined. This size defines the number of records that must be exceeded to create a new PSA partition. One request is contained in one partition, even if its size exceeds the user-defined PSA size; several packages can be stored within one partition.
The PSA is partitioned to enable fast deletion (DDL statement DROP PARTITION). Packages are not deleted physically until all packages in the same partition can be deleted.
3. Export Datasource:The Export DataSource (or Data Mart interface) enables the data population of InfoCubes and ODS Objects out of other InfoCubes.
The read operations of the export DataSource are single threaded (i.e. sequential). Note that during the read operations u2013 dependent on the complexity of the source InfoCube u2013 the initial time before data is retrieved (i.e. parsing, reading, sorting) can be significant.
The posting to a subsequent DataTarget can be parallelized by ROIDOCPRMS settings for the u201Cmyselfu201D system. But note that several DataTargets cannot be populated in parallel; there is only parallelism within one DataTarget.
Hope it helps!!!

Manage ODS : Difference of Transferred Records and Added Records

Hi there,
When I click on Manage ODS , I have the following fields
Transferred Records and Added Records.
Please advice the difference

Hi,
Transferred Record coloumn indicated how many records were tranferred from the source system to BW,means how many records were extracted at that point of time and another Column indicates that the total number of records added to your data target.these two cloumn vales may not be same for all the time,becoz if you have filters at the update rule level....in this case numbers records tranfered and numbers records added might be different.......
Transferred refers to the number of records that are transferred from the datasource (arrive in BW). Added is the number records inserted into the ODS. Both can be different numbers, like due to any processing of the data.
Added records refer to which is really inserted in ODS (your start routine, for example, can reduce the number of transferred records by deleting something!)
Ex
transferred records means the total records from source e.g ods. say data coming from ods
docnumber docitem customer qty
001 1 x 10
001 2 y 20
002 1 x 30 (3 records)
and your infocube has char customer and keyfigure qty, so
record added
customer qty
x 40
y 20 (2 records)
so here you have transferred records = 3 and added records = 2

Probelm in Deleting INFOCUBE/ODS?

Hi ,
I'm trying to delete the Bussiness content CUBE and ODS,
Getting error when to delete Cube "Infoprovider "xyz" is not use Externally"
ODS error " Infoprovider "xyz" set to INACTIVE.
Please advice how to delete the CUBE/ODS in BI7.0 version.
Thanks,
Srini.

Hi,
Check if your ODS is in active state?
Thats what I understand from the error message.

How to find infocube,multiprovider ,ods in the system

Hi,
How to find active infocube , ods,datasource,infosource,query and multiprovider list in the system.
Please guide Me

Hi naam,
If you are in BI 7.0,at modelling tab you have find option if u click on this it gives u many check boxes with option as infocubes,infoobject,infosources of 3.x and 7.0 also,DSOs ..etc.

ODS objects and Info-cubes

Could someone clarify my understanding of the difference between ODS and basic cubes?
My understanding is that the ODS is updated from R/3 and is a flat structure, or a basic database which is write-optimised. The data in the ODS is then updated into the info-cube at a more summarised level.
The info-cube provides enhanced reporting capability because it is structured as a star-schema which introduces additional dimenions (via the dimension tables) to enrich the contents of the fact table.
Does the ODS update both fact table and dimension table in the star schema?
Many thanks,
Frederick

Hi Frederick,
If that doesn't solve your concern... then go ahead
1.ODS is a two dimensional object
2.ODS is a datastore where you can store data at a very granular level.
3.Technically there is the option to overwrite or add single records.
4.ODS can be used for detailed level of reporting( same as in r/3),
(cube can be used for aggregate level of reporting.)
5.ODS are used to consolidate data
1.Whereas cube is a based on multidimensional modeling which facilitates reporting on diff dimensions.
2.The data is stored in an aggregated form unlike ODS and have no overwriting capability.
3. Reporting and analysis can be done on multidimensions unlike on ODS
4. InfoCubes are optimized for reporting
5. There are options to improve performance like aggregates and compression.
5. It is not possible to replace single records, all records sent to InfoCube will be added up.
You may get a doubt why first load to ODS and then to Infocube, the strategy of adding ODS
in dataflow is termed as addtion of EDW(Enterprise Datawarehouse) layer which will allow
us to retrieve data within BW if at all some thing goes wrong & we lose data from InfoCube.
We can get the data from ODS itselft into cube without going to the source sytem again.
Please search SDN & you will get a lot of docs on this:

DIfference between BW and R/3 Security

Hi
Please tell me whats the difference between BW and R/3 Security
Thanks

Hi,
The main difference is that, in R/3 the first line of defence it S_TCODE, i mean its completely based on Transaction.
Where as B/W is completely object based i.e, it deals with securing Infoobjetcs, Infocubes, ODS, BW Queries, etc....

Two clients using RSA1 and their infocubes and queries

Hello,
I have a doubt.
My client has a SAP BW 3.5 with the client 100 for example. Now he want to have a backup of the client 100 in client 200 but still use the 100 and sometimes view the data in the 200.
In the client 100 with have new data and erase the old data.
But as what I know, I can't execute the Tcode RSA1 in the 2 clients. It only works in the client where I have set in the RSADMIN.
Is there a wat to see the two? I mean the infocubes, ODS of the 2 clients using the RSA1?.
Can I check the data (queries) with the Query Designer o Query Analyser of the Bex?
Please I need your help.
Thank you in advance. It's a little urgent.
Best Regards...
Pablo Mortera.

Pablo,
The basic difference between BI and ECC (R/3) is that R3 is client specific but BI is not. There are few ways you can do it.
1. you could have multiple layers such as Data Ware House layer, Application layer or Evene an additional DSO to have the history.
2. Archival is another way of taking the backups.
I am not sure or not seen where they backup the working query, because these objects cannot be deleted from production anyway as the box is locked against any changes. But BW delevoper who has access to info provider in any environment can delete the content and only way to avoid that is having a backup DSO and try not to delete the data.
Goodluck,
Alex.

ODS vs IC

hi gurus,
            please tell me Difference b/n ODS & IC
           ThanQ.
    Regards,
   Ramesh.

Hi,
Diff btw ODS and cube
1. ODS having the Over write functionality but Cube contains the Additive
functionality
2. ODS is Two Dimentional Data Container but Cube is Multi Dimentional..
3. In ODS Characterstic will be called as a Key Field Nd Keyfigure called as a
Data Field But in Cube the Characterstic Nd Key Figures only..
4. In ODS data will be in Flat and Transparent model but In Cube data will be in
Star Schema Model.
5. ODS contains Current data but Cube Contanis Historical Data..
6. ODS maintains in 3 different tables but Cube can't
7. In ODS can extract from diffenrent datasources but cube can't
8. In ODS data can't be summarized but In Cube data Can be Summarized /
Aggregated.
9. ODS is not suggestable for Reporting always but Cube is suggestable for
better Granularity.
Yah Exactly for Reporting purpose generally data will be taken from the InfoCube for bettter reporting i.e., In the Level of Granularity..
ODS is not always suggestable for Reporing, why because if u use ODS directly to the Reporting the OLTP performance will degrades why bcoz it takes current data..
So always load into Cube via ODS for better reporting..

Difference between data target & Infoprovider.

Hi all,
Difference between data target & Infoprovider.
why cube is best in performance wise other than ods,multiproviders.
Thanks,
cheta.

A data target is an object into which data is loaded. Data targets are the physical objects relevant during data modeling and when loading the data.
Structure
Data targets are:
InfoCubes
ODS objects
InfoObjects (characteristics with attributes, texts or hierarchies).
There are differences between:
Pure data targets for which no queries can be created or executed. An InfoCube might only be used as a data source for another InfoCube. This is also possible for ODS objects and InfoObjects.
If you want a characteristic to appear in the InfoProvider tree, you have to assign an InfoArea to it. You can define update rules for the characteristic in the InfoProvider tree, and use them to load attributes and texts.
You can turn a characteristic into a data target only if the characteristic contains texts or attributes. It is not possible to use update rules to load hierarchies.
Data targets for which queries can be defined. These are called InfoProviders.

Data in the cube/ ODS?

Hi all,
I would like to ask one simple question. Can someone tell me how to check if infocube/ ODS contains data (instead of checking it by runing reports in BW Analyzer). Thank you.
Best wishes,
John

Hi John,
In RSA1, find your cube or ODS > right click > Manage > Requests tab. Here you can see the data that has been loaded to the object.
You can also move to the contents tab and look at the contents from here, or at least click on Number of records to get an idea of the volume of data.
Or in SE16 > /BI/A<b>YrODS</b>00 for the ODS active data table and /BI/F<b>YrCube</b>for the cube fact table.
Hope this helps...
