What is the difference between DSo and Infocube

Hello,
Kindly tell me what is the difference between DSO and Infocube?
And please tell me how to take the desicion that in whichi case we can use DSO and in which case we can use Infocube..

Hi ,
DataStore object serves as a storage location for consolidated and cleansed transaction data or master data on a document (atomic) level.
This data can be evaluated using a BEx query.
A DataStore object contains key fields (for example, document number/item) and data fields that can also contain character fields (for example, order status, customer) as key figures. The data from a DataStore object can be updated with a delta update into InfoCubes and/or other DataStore objects or master data tables (attributes or texts) in the same system or across different systems.
Unlike multidimensional data storage using InfoCubes, the data in DataStore objects is stored in transparent, flat database tables. The system does not create fact tables or dimension tables.
Use
The cumulative update of key figures is supported for DataStore objects, just as it is with InfoCubes, but with DataStore objects it is also possible to overwrite data fields. This is particularly important with document-related structures. If documents are changed in the source system, these changes include both numeric fields, such as the order quantity, and non-numeric fields, such as the ship-to party, status and delivery date. To reproduce these changes in the DataStore objects in the BI system, you have to overwrite the relevant fields in the DataStore objects and set them to the current value. Furthermore, you can use an overwrite and the existing change log to render a source delta enabled. This means that the delta that is further updated to the InfoCubes, for example, is calculated from two successive after-images.
An InfoCube describes (from an analysis point of view) a self-contained dataset, for example, for a business-orientated area. You analyze this dataset in a BEx query.
An InfoCube is a set of relational tables arranged according to the star schema: A large fact table in the middle surrounded by several dimension tables.
Use
InfoCubes are filled with data from one or more InfoSources or other InfoProviders. They are available as InfoProviders for analysis and reporting purposes.
Structure
The data is stored physically in an InfoCube. It consists of a number of InfoObjects that are filled with data from staging. It has the structure of a star schema.
The real-time characteristic can be assigned to an InfoCube. Real-time InfoCubes are used differently to standard InfoCubes.

Difference between Infoset and Infocube?

Hi All,
Difference between Infoset and Infocube?
Please suggest on this .
Thanks & Regards
Sameer Khan

Hi,
In infoset we can join Infocubes,DSOs,Mater data table.It works on join codition.
For ex: I want to generate a report with cobination of MM and SD field.which are available in my MM amd SD cubes.So that i'll creat a infoset and join these two cubes.Then i can ablle gerenat a required report.But here codition is that 'One common field is must in both cubes' then only it works.
Infocube is a MDM model.

Please write the difference between ODS and DSO...

Hi all,
Please write me the differences between ODS and DSO.. I think both are same in structure and have same update types (Over write, Addition) and also with the tables (changelog, Activation queue, Active table).. Is there still a difference between ODs and DSO...I can assign the points..
thanks

What is the difference between ODS and PSA?

DIFFERENCE BETWEEN ODS AND PSA?

hi..
ODS:
Stores consolidated data on the document level.
Data is stored in transparent tables.
Reporting is possible.
Represented on the database by three transparent tables.
Stores Transaction data.
Can merge data from different infosources.
Can be defined as a datasource for another Bw system.
ODS has granular data, it is volaital.
ODS having the Over write functionality
contains Current data
PSA:
It is source system dependent.
Stores data in 2-D format.
We can edit data in PSA.
Reporting is not possible.
used mainly for performing manual update or simulate update or reconstruction.
partition is possible.
Data stored in psa can be used for several purposes.
Repeated delta updates possible.
Error handling posibility.
Structure of PSA is called as Trasfer structure.
It stores the data exactly like how the data is presented in the source system.
We have psa and ODS but we can't do reporting on PSA
You can do reporting in ODS , In PSA u cant do reportin directly
ODS contains detail -level data , PSA The requested data is saved, unchanged from the source system. Request data is stored in the transfer structure format in transparent, relational database tables in the Business Information Warehouse. The data format remains unchanged, meaning that no summarization or transformations take place
In ODS u have 3 tables Active, New data table, change log, In PSA u dont have
We can only add in PSA and change, add and delete in ODS.Is the statement true?
we can edit/add the records in PSA and delete the records,
i thjink its not possible to edit the records in ODS, u can delete the records, and u can add records in ODS
check out this link..

hope it helps..

Data Mismatch between ODS and Infocube

Hi,
I have got data mismatch between from ODS to Infocube. In ODS for one Sender Cost Centre, there is only one Company Code. In Infocube it is showing many.For ODS datasource is 0HR_PT_1. In Updaterules of ODS, Company Code was assigned to Company Code. But in Infocube should I assign CompCode to Comp Code or any other Characteristic as Master Data Attr of. Plz suggest us.
It is very urgent.

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....

What is the difference between upgradation and migration.

Hi Guru's
what is the difference between upgradation and migration.
actuallly i involved in upgradation project, here my role is
1. first i check the query's in 3.5 save the query and transport the query. and check the query in bex analyzer also.
2. go to BI .7 find the query;s ,give the query name and save the query ,
3. once save the query, again will come to 3.5 open the query , it will not open. this is my job here,
come to 7.0 check the query in analyzer also.
i am having littile bit confusion, how it will comes query in 7.0, why are u saving the query's in 3.5 and 7.0
query's already available in 7.0 why are u doing this work?
can i know the upgrades those objects, is it neccessary, if necessary how can i upgrade.
infoobje , transferrules, transferstructure ,infosoure, datasoure,updaterules, ods, cubes.
Points will be Assingned ,
Thanks & Regards
prabhavathi

Hi,
I was talking in a general sense not on a query level.
If your taling about migration in that level meaning as a part of larger upgradation (in your case 3.x to 7) there may be many places where you need to do this kind of activities.
Fr eg migration into new data flow, Migration of Web templates from BW 3.x to Netweaver 2004s, etc
Hope this helps.

Difference Between Aggregates and Compression

Hi,
Can you tell me what is the difference between Aggregates and Compression?
I know ,once compressed data is not available for deletion in request wise
and it moves from F table to E table .
Aggregates means ,data will move from cube to aggreagates(Baby cubes).
But my query is ,As both of them aggregates the data.which of them should be used. at what situation?
I hope you understood my Query.
Regards.
Naresh.

Hi,
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form into the database.
Aggregates make it possible to access InfoCube data quickly in Reporting. Aggregates serve, in a similar way to database indexes, to improve performance.
especially in the following cases we create aggregates:
The execution and navigation of query data leads to delays with a group of queries.
You want to speed up the execution and navigation of a specific query.
You often use attributes in queries.
You want to speed up reporting with characteristic hierarchies by aggregating specific hierarchy levels.
For more info on aggregates go though the link below
https://help.sap.com/saphelp_sem320bw/helpdata/en/c5/40813b680c250fe10000000a114084/frameset.htm
Compression creates a new cube that has consolidated and summed duplicate information.
2. When you compress, BW does a group by on dimensions and a sum on measures... this eliminates redundent
information.
3. Compressed infocubes require less storage space and are faster for retrieval of information.
4. Once a cube is compressed, you cannot alter the information in it. This can be a big problem if there
is an error in some of the data that has been compressed.

Difference between reconstruct and reload?

Hi All,
1.What is difference between reconstruct and reload?
2.User exits for variables? Examples.
3.Your delta failed from R/3. No records in extraction queue and delta queue. How would you get those records?
4.ODS has 5 requests? If bottom request is removed would top request be affected?
5.Web application developer experience. Did you work on BPS?
6.Experience working with Info Hub?
thanks,
deen

hi,
reconstruction: means we get same request data from PSA to data target.
reload: reload means again the data is loaded with new request number.
your 3rd quesition is not clear
2 ans.For variable with customer exit we have one enhancement that is RSR00001.If u want to populate data to u r variable dynamically then we gofor this exit.We can do this in CMOD transactin code.
3 ans.yes there is effect.the top request are deleted.

Difference between BCS and BPC

Hi Experts,
Can Someone explain me what is the difference between BCS and BPC.
Thanks in Advance

BCS is developed by SAP and uses BW for the data storage, as well as other BW objects for master data and virtual infocubes with imbedded consolidations logic for reporting. This is, in my opinion, the most dynamic consolidations too and best for more complex scenarios.
BPC is the purchased Outlooksoft tool that does not until recently include the use of BW, and is better for simple consolidations scenarios.
SAP can provide more information regarding both.
There is yet another tool, previously know as Cartesis, and now called SAP Financial Consolidations. This is also better than BPC for complex scenarios.

Difference between Null and null?

What is the difference between null and NULL?
When is each used?
Thanks,

veryConfused wrote:
There is a null in java, but no NULL. null means no value. However, when assigning value, the following is different:Although the empty String has no special role. Null means, the referential type is not assigned (doesn't refer) to a specific object. The empty String is just another object though, so seeing it or pointing it out as something special when it actually isn't at all (no more special than new Integer(0) or new Object[0]) just adds to the confusion.

Difference between GUI_UPLOAD and WS_UPLOAD

Hi,
Please make me clear about the difference between GUI_UPLOAD and WS_UPLOAD. In which cases we need to use these modules...??
Thanks,
Satish

I would suggest to always use the GUI_UPLOAD. I say this because this is the function module which is used in the GUI_UPLOAD method of the class CL_GUI_FRONTEND_SERVICES.   Really, you should probably use the class/method instead of the function module.
data: filename type string.
filename = p_file.
call method cl_gui_frontend_services=>gui_upload
         exporting
              filename                = filename
              filetype                = 'ASC'
         changing
              data_tab                = iflatf
         exceptions
              file_open_error         = 1
              file_read_error         = 2
              no_batch                = 3
              gui_refuse_filetransfer = 4
              no_authority            = 6
              unknown_error           = 7
              bad_data_format         = 8
              unknown_dp_error        = 12
              access_denied           = 13

Difference between char and varchar, also the difference between varchar2

Hi,
Can anyone explain me the difference between char and varchar, and also the difference between varchar and varchar2...

Varchar2 is variable width character data type, so if you define column with width 20 and insert only one character to tis column only, one character will be stored in database. Char is not variable width so when you define column with width 20 and insert one character to this column it will be right padded with 19 spaces to desired length, so you will store 20 characters in the dattabase (follow the example 1). Varchar data type from Oracle 9i is automaticlly promoted to varchar2 (follow example 2)
Example 1:
SQL> create table tchar(text1 char(10), text2 varchar2(10))
2 /
Table created.
SQL> insert into tchar values('krystian','krystian')
2 /
1 row created.
SQL> select text1, length(text1), text2, length(text2)
2 from tchar
3 /
TEXT1 LENGTH(TEXT1) TEXT2 LENGTH(TEXT2)
krystian 10 krystian 8
Example 2:
create table tvarchar(text varchar(10))
SQL> select table_name,column_name,data_type
2 from user_tab_columns
3 where table_name = 'TVARCHAR'
4 /
TABLE_NAME COLUMN_NAME DATA_TYPE
TVARCHAR TEXT VARCHAR2
