Delta between DSO and Cube

Hi All,
I have been working on a scenario where in we have to realign org structure information of some sales orders , now we have existing sales orders data in DSO , which feeds to a cube . As part of the realignment some master data attributes, more specifically Customer Master attributes, will be changed in R3 for those Sales Orders.
These attributes are part of the transaction data load which is happening to the DSO from the source, now since this transaction load is taking time, to speed up the process of realignment in BW I have used a routine to lookup the masterdata attributes from 0CUSTOMER in BW.
so before BW pulls the realigned data ( Sales Orders ) from R3, I will run a self loop in the DSO where in it will do a lookup in the 0CUSTOMER master data in BW to get the updated customer attributes (ofcourse the 0CUSTOMER load will happen before we do any realignment of the source data) .
Once the self loop transformation is completed and the sales orders are updated with the updated customer attributes, I will load the data to the cubes. (delta load)
Now once the sales order realignment is finished in R3 , I will pull the same set of data in the DSO .
Now the question is, is it necessary that I do a reinit of the cube before I load the second set of data to the cube?
I guess it is not necessary.
Please share your thoughts.

Hello Partho
I understand your KF are overwrite in DSO. But in BI7 flow delta from DSO to cube is request based.
When you will do a self-loop, same records ( I guess you have already loaded them to cube) will have different request id.
As a result your Change Log table will get different id after activation. So same record will get loaded to cube and which will make all your KF in cube doubled.
I believe to make correction in historical records in cube either you have to delete cube content and then run delta from DSO to cube. As first time delta will read Active table of DSO you will get all KF correct in cube..
Else, you have to delete all those previously loaded record from cube selectively.

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.

Data in DSO and CUBE

Hi Experts
Please..Please update me on in detail if possible with example ......Key Fields and Dimensions
How Data Records will be processed in DSO and Cube
I tried to search but i can't able to find what i am looking for
My Requirment:
I am extracting Employee Benefits records from Non SAP Source System (Oracle Tables)
In the Oracle there is no Date field avaliable and there won't be any history avaliable in oracle once the Benefits of an employee is changed the old record will be overwritten to new one so they can't track the employee benefits history...but in BW i need to store/show history of employee benefits by Cal day
Oracle Table Fields
Location (Primary Key)
Emp No (Primary Key)
Insurance Type
Call Allowance Type
Annual Leave (No of day Days)
Pension Schem
Company Laptop (Yes/No)

hi,
key fields are the primary keys of ur ods tables. based on the key field values the data fields will get overwritten.
suppose if the key fields values were same then the data fields will get overwritten. but the changes were captured in the change log table, hence the history of changes is available.
Dimensions- are the prmary keys of cube. but in cube only addition of records will happen as default not overwrite as in ods.
dimension ids were generated based on the sid values of characteristics.
maximum of 16 key fields and dimensions can be there in ods and cube respectively.
for ur case, include 0calday field in the key fields and use the routine to update the field with system date(SY-Date). this keeps track/ else without date also , change log maintains history for each load.
have to add 0recordmode to the communication structure of the ods(infosource).

Automatic mapping of fields in transformation between DSO and Infosource.

Hello BI Experts,
When i migrate the update rule between DSO and infosource in to transformation, the log of successful copy of routines and hence the creation of transformation appears. But when i open the transformation for activating it, there is no mapping between the fields as well no routines appear.
Please suggest me the way out of it.
Points will be assigned.
Regards,
Vinayak

VGM,
By the way how are you migrating the routines into BI 7 from 3.x??? And moreover the update routine has to be a local routine in BI 7 or else a start routine or else end routine??? You need to decide where it will be applicable and then copy the old code and modify it and paste the same. If you are creating any start or end routines to populate data for some object, do remember that the objects should map with any one of the object from Infosource.
Hope this helps

What is the difference between, DSO and DTP in BI 7.0

Hi Guru's
what is the difference between, DSO and DTP in BI 7.0 , how it will come the data from r/3 to BI 7.0, can u discribe?

Hi,
The data will be replicated in the same way as we do in 3.5.

How can i update data of DSO and Cube using ABAP??

Hello Experts
I have a requrement in which i need to update/ delete data from DSO and cube based on certain keys using ABAP.
Please let me know how can i modify contets of cube or active table of DSO.
Thanks
Sudeep

Hi
I have requirement such that i need to update certain key figures in DSO after certain time.
for eg. say record with key a is loaded to DSO and currospoding key figure was loaded with value 10
after few days because of certain parameters changing in system i need to modify key figure value.
currently i am doing same using 1 self transformation i.e. by loading same data again in same DSO.
Amount of data is very huge and causing performance issues in system.
now A is not key but i need to modify record for few combinations which apperar multiple times in DSO.
Same DSO data is loaded into Cube regularly.
I may need to update data after gap of few weeks as well.
This design will be used as template and needto keep whole logic generic.
So wring Function module can make it generic.
Thanks
Sudeep

Is the concept of Transactional DSO and Cube in BI 7?

Hi,
Is the concept of Transactional DSO and Cube in BI 7?
I see 3 type of Cubes[Standard or VirtualProvider (Based on DTP, BAPI or Function Module)]
but canu2019t see transaction Cube.
also
I see 3 type of DSO(Standard, Write-optimized, Direct update )
but canu2019t see transaction DSO
See this link on DSO, with examples etc:
http://help.sap.com/saphelp_nw04s/helpdata/en/F9/45503C242B4A67E10000000A114084/content.htm
I am looking for such summary also for Cubes have you see a similar one?
Thanks

New terminology in BI 7.x
Transactional ODS = DSO for direct update
Transactional Cube = Realtime Cube

Why do we create indexes for DSOs and Cubes.What is the use of it?

Hi All,
Can you please tell me why are indexes created for DSOs and Cubes.
What is the use with the creation of indexes.
Thanks,
Sravani

HI ,
An index is a copy of a database table that is reduced to certain fields. This copy is always in sorted form. Sorting provides faster access to the data records of the table, for example, when using a binary search. A table has a primary index and a secondary index. The primary index consists of the key fields of the table and is automatically created in the database along with the table. You can also create further indexes on a table in the Java Dictionary. These are called secondary indexes. This is necessary if the table is frequently accessed in a way that does not take advantage of the primary index. Different indexes for the same table are distinguished from one another by a separate index name. The index name must be unique. Whether or not an index is used to access a particular table, is decided by the database system optimizer. This means that an index might improve performance only with certain database systems. You specify if the index should be used on certain database systems in the index definition. Indexes for a table are created when the table is created (provided that the table is not excluded for the database system in the index definition). If the index fields represent the primary keys of the table, that is, if they already uniquely identify each record of the table, the index is referred to as an unique index.
they are created on DSO and cube for the performance purpose ..and reports created on them wil be also more efficent ..

'Get All New Data Request by Request' option not working Between DSO n Cube

Hi BI's..
Could anyone please tell me why the option ' Get one Request only' and 'Get All New Data Request by Request' is not working in DTP between Standard DSO and InfoCube.
Scenario:
I have done the data load by Yearwise say FY 2000 to FY 2009 in Infopackage and load it to Write-optimised DSO (10 requests) and again load Request by request to Standard DSO and activate each request. I have selected the option in DTP's to 'Get All New Data Request by Request' and its working fine between WDSO and SDSO. But not working between Cube and SDSO. While Execute DTP its taking as a single request from SDSO to Cube.( 10 request to single request).
Regards,
Sari.

Hi,
How does your DTP setting looks like from below options ? It should be change log, assuming you are not deleting change log data.
Delta Init. Extraction from...
- Active Table (with archive)
- Active Table (without archive)
- Archive ( full extraction only)
- Change Log
Also if you want to enable deltas, please do not delete change log. That could create issue while further update from DSO.
Hope that helps.

Data is not coming correctly through delta from DSO to Cube

HI All,
When there is change in Org. Unit, Job or any characteristic of employee then the the delta of data source picks that change records.
I have used DSO before Cube. Now in DSO active table have one record against the Employee and same Schedule hours as ECC have.
But while loading to the cube, this data of schedule hours will get added to existing schedule hours of Cube , which makes the schedule hours double for that Employee. For exmaple.
DSO Data.
Emp NO.     Date Org. Unit     Sch. Hrs
1                    ABC                              16
CUBE Data
Emp NO.     Org. Unit     Sch. Hrs
1                    ABC               16
Now Employee Org. Unit get changed to XYZ.
DSO Data.
Emp NO.     Org. Unit     Sch. Hrs
1                    XYZ               16
CUBE Data
Emp NO.     Org. Unit     Sch. Hrs
1                    ABC               16
1                    XYZ               16
I need data as it is in the DSO.
Please help, thanks in advance.
Arvind

Hi Arvind,
DSO and Infocube works different for char values......you can define Key Fields in DSO...
whereas in Infocube each Characteristic value work as Key Field.....that's the reason if there is any change in any characteristic value ...
DSO Active data will not change if Key field has not change..... the newly updated Data field value will be available in DSO Active Table.....whereas in Infocube... it will create a new entry......
In order to get the updated value each time you need to explore some other options .....like complete deletion of Info cube data and full load everyday.......
Other options depends on design and data volume and other parameters.
Hope this helps........

DATA_PACKAGE between ODS and Cube

Hi SDNs,
I try to do the simulated update from ODS to Cube in the monitor of cube.there are two data packages under processing item.The first one ( A1 ) contains 39393 records, and the second one( A2 ) contains 32872 records.
Then I search the infosource generated by ODS( 8 * ), I find there are 4 data packages ( B1 19391,B2 20002,B3 19595,B4 13277) under the same request number, so it seems that one data package in the monitor contains two ones under the infosource(8*).
My issue is that when I dubugging the data package under monitor, I can only find B1 in A1 and B3 in A2, the B2 and B4 are disappeared...
Why?
Thanks a lot
Sam

Probably because you did not use the PSA to upload the data.
Best regards
Dirk

Delta between cube and ods

I have existing deltas between ods into cube.
Now, new deltas into cube are failing for lack of init!
A new init is not possible from ods to cube, because there is already one in infopak.
Problem is "The data mart status on the ods is empty."
I need help in setting this datamart status to being init done, is there an table fix?
What tables are involved in this ?
Thanks
Gopi

RSDMDELTA table stores the datamart status of requests.

New field added to cube, delta DTP from DSO to cube is failing

Dear all,
Scenerio in BI 7.0 is;
data source -delta IPs-> DSO -
delta DTP---> Cube.
Data load using proces chain daily.
We added new field to Cube --> transformation from DSO to cube is active, transport was successful.
Now, delta from DSO to cube is failing.
Error is: Dereferencing of the NULL reference,
Error while extracting from source <DSO name>
Inconsistent input parameter (parameter: Fieldname, value DATAPAKID)
my conclusion, system is unable to load delta due to new field. And it wants us to initialize it again ( am i right ?)
Do I have only one choice of deleting data from cube & perform init dtp again ? or any other way ?
Thanks in advance!
Regards,
Akshay Harshe

Hi Durgesh / Murli,
Thanks for quick response.
@ durgesh: we have mapped existing DSO field to a new field in cube. So yes in DTP I can see the field in filter. So I have to do re-init.
@ Murli: everything is active.
Actully there are further complications as the cube has many more sources, so wanted to avoid seletive deletion.
Regards,
Akshay

DSO to Cube Delta Failure

Hi All
We appear to have a major problem.
Yesterday the invoice delta from DSO to Cube failed. My colleage traced the problem to invalid characters in the PSA. However it had loaded successfully into the DSO (I dont know why cos it usually fails into DSO if invalid chars are present).
So we deleted that request from the DSO (even though it was green), fixed the invalid chars in PSA and then manually updated from PSA to DSO. Fine all went well so far.
Then we ran the delta load from DSO (datamart) for cube but this came back with error saying 'Previous delta has not finished so cannot proceed' All monitors were RED status but still no good. So we left it thinking that todays process chain run would fix it.
But it didnt. The error today is 'Delta update for ZINV_CUBE is invalidated. Message no. RSBM113'
The data in the DSO is all correct and upto date. However the datamart status for all requests (going back to Nov 2007) is missing. In the infosource view the outgoing request (REQU_) for Yesterday is missing and todays REQU has red status. Yesterdays incoming request (ODSR_*) is followed by todays incoming request.
From reading previous posts I think I need to do initialise without data transfer, but will that leave the cube with 2 missing requests (today and yesterday). How do I get them into the cube ?
I could delete the cube contents and perform init with data but I dont feel comfortable as it involves nearly 2 years worth of data. Also will all DSO requests get rolled up into a single cube request ?
All advice very much appreciated
Asif

Hi,
Hope so the requests for today and yesterday is there in PSA....
Now change the RED status of the failed requests in DSO and cube manually to RED i.e QM status...here only u have faced the issue that previous delta was not yet finished...
U can chk in SM12 for any locks present....
Now u can delete the requests in cube(this will delete the data mart status from ODS) followed by DSO...
Now first u load the data to the ODS manually, activate the ODS and then uplaod it to cube manually thru additional function->update data to targets->Delta update and continue...this'll load the complete data for the two days...
No need to perform INIT if the data is presetn in PSA....
