ODS vs DWH vs DM
hi guru
whats diff between ODS vs DWH vs DM?
anand
hi anand
DSO
- Acts as source to populate DW and marts
- Often used for operational reporting
- Detailed, atomic data
- Huge data volumes
- Integrated, clean data
- Cross-functional and cross-departmental
- Supports data mining
- May use denormalized form modeling (NOT dimensional)
DWH
- Provides mgmt reporting
- Summarized data
- Tuned to optimize query performance
- Multiple departments or processes
- May act as staging area for data marts
- Uses dimensional data modeling
DMart
- Specific application or workgroup focus
- Narrow scope
- Customized or stand alone analysis
- Interactive query
- Highly summarized
- Single subject and department oriented
- Uses dimensional data modeling

Incremental load not capturing data in SSIS 2012
Hi ,
Iam having an issue with Oracle CDC for SSIS which is new in 2012, Developed SSIS packages with Full load and Incremental load logic to load data into ODS - STAGE - DWH. Here problem is when ever i do a full load following with an incremental load , incremental
load is not capturing updated data , if i do second incremental load then it captures data.
Is there any solution for this to get data in first incremental load.Are you sure it picks up LSN correctly? I doubt its CDC service not picking the correct LSN value which it uses to identify the changes.
It should be in cdc.lsn_time_mapping table I guess

Hai Experts,
Can any body tell me data is present in active data table, new data table, change log table and as wel as with this there is a content button it is asking for the table name what is that button consists of can any body help me out
Regards,
VikramHi Vikram,
If we right click ODS --> go to Manage --> contents Tab
You will find three Tables
1. New Table : when you load Data initially it gets into New Table and if you click on that you can see the Content
2. Active and Change Log : when you Activate data in ODS the Data moves from new to active and change log Tables and used for futher processsing to other Data Targets like Cube or ODs again.
Change Log Table records all the changes happend to the data.

Pls ck this blog.
No bef and aft Images in ODS.
/people/raj.alluri/blog/2006/11/24/the-tech-details-of-standard-ods-dso-in-sap-dwh
0recordmode is the field added by the system, if the datasource is delta capable.0recrodmode controls how data is posted into cubes or ODS (DSO) Objects.
N for new records
B for Pre Imgages
' ' for after images
R for Reverse Images
X for Storno
D for Deletion of a Key (only in ODS possible)
Y-Update image
check this thread which tell s in detail about the Orecordmode and ROCANCEL

BW Experts,
I have a new ODS and have loaded data in it. When I rt click on the ODS and choose manage and then if I want to see the contents of the ODS I am getting the following error.
<b>System error: RSDRC / FORM AUTHORITY_CHECK USER NOT AUTHORIZED ZSD_O01 ZSD_O01
Message no. DBMAN100
Diagnosis
A system error with the following parameters has occurred in the data manager:
Parameter 1 = &v1&
Parameter 2 = &v2&
Parameter 3 = &v3&
Parameter 4 = &v4&</b>
However, I can still see my data through my active data table tab.
Any thoughts on why I am getting this error when I want to see it directely through manage ods?
Thanks
AshwinHi Ashwin,
Is the ODS enabled for reporting? I came across a similar situation recently and it was because I did not have the auth for data access for that particular ODS. I could look at the data through SE16 and the active data table, but not if I did a LISTCUBE for it.
After it was added to a role and assigned, the error message was removed. (Auth object: S_RS_ODSO)
Hope this helps... -
Dsatsource /ODS/Cube for Open PR and Open PO"
Dear Experts
I want to build a report in which I need to show "Open PR and Open PO" but I could not locate these fields in the BW CUBE / ODS / DATASOURCES. Can anybody tell me where I can find these fields..........
Dinesh SharmaDear,
There is no specific standard data source is not available to fetch us "Open PO" or "Open PR". first vll talk about PO.
For open PO,
case - 1
Need to report count of all PO's which are in open status.
Case-2
Need to report TBQ ( to be delivered Qty ) against each over due PO.
Basically we have - EKKO - HEADER , EKPO - ITEM AND EKET - SCHEDULE LINE ( GRC - GOODS RECEIVED ) is available,
so create a view, take all these three tables EKKO, EKPO and EKET.
EKPO
1 DELIVERY COMPLETED INDICATOR ELIKZ
1 DELETION INDICATOR IN PD LOEKZ
1 ARTICLE NUM MATNR
1 SITE WERKS
X PO DOCUMENT NUM EBELN
PURCHASING ORDER QUANTITY MENGE
PURCHASING ORDER UOM MEINS
NET ORDER VAL IN PUR ORDER CURRENCY NETWR
NET PRICE IN PURCHASING DOC IN DOC CURRENCY NETPR
no PRICE UNIT PEINH
X ITEM NUMBER OF PURCHASING DOCUMENT EBELP
EKKO
DATE ON WHICH RECORD WAS CREATED AEDAT
PURCHASING DOCUMENT DATE BEDAT
DELIVERY DATE EQ_EINDT
RELEASE INDICATOR PURCHASING DOC FRGKE
RELEASE STATUS FRGZU
0PO_UNIT PURCHASING DOCUMENT NUM EBELN
CURR KEY WAERS
EKET
QUANTITY OF GOODS RECEIVED WEMNG
PURCHASING DOC NUM EBELN
ITEM NUM OF PURCHASING DOC EBELP
Logic - create a generic DS, by view, FIRST send the data to DSO, there mention a field like TDQ ( to be deliver qty ), TDQ = po qty - goods received qty. -
create a cube above DSO, set a filter, allow only those records who has TDQ <>0, so your cube contains only pending PO.
hope it helped u.
Thanks, -
Error while creating the DWH tables using DAC

Thanks,
RMThe fact that you are getting an "ORA-01017: invalid username/password; logon denied" message indicates that you are at least talking to the database.
The log shows that username "infdomain" is being used. Can you double check the username and password you have in DAC in a SQL*Plus/SQL Developer session?

Error while activating ODS Object
Hi,
I have loaded the data from R/3 to a ODS Object and the activation of ODS failed due to the following errors as shown below..
-Value '20060 ' of characteristic 0CALQUARTER is not plausible
-Error when assigning SID (details in long text)
-Activation of data records from ODS object ZODS_02 terminated
-Error getting SID for ODS object ZODS_02
I could see that Calendar Quarter as 20060 in PSA. How should i get rid of this error. Any idea would be appreciated.
Regards,
RajRaj,
you are getting this calender qurter from SAP right... check in RSA3 fro the your Datasource. if you are getting same value like '20060'. you can do one thing... you can set 'No Update' in Transfer Rules. you can write a routine in Update Rules for populating the data for calender Week.
you can call some standard function modules or you can write a small routine. If you want to write a routine check this thread...Re: Date to Quarter
Possibilites:
1. updtae rules
2. if RSA3(PSA) shows the value of the Quarter as '20050', if it is custom extractor(Generic using FM) you can change this.
3. If it is Standard Extractor or Generic Extractor (using either view/table or Infoset) you can enhance this. you can do the same thing in SAP Side.
All the best.

Error while updating data from PSA to ODS
Hi Sap Gurus,
I am facing the error while updating data from PSA to ODS in BI 7.0
The exact error message is:
The argument 'TBD' cannot be interpreted as a number
The error was triggered at the following point in the program:
GP44QSI5RV9ZA5X0NX0YMTP1FRJ 5212
Please suggest how to proceed on this issue.
Points will be awarded.Hi ,
Try to simulate the process.That can give you exact error location.
It seems like while updating few records may be no in the format of the field in which it is updated.

Error while resetting the delta in ODS (BI 7.0)
Hi all,
I face a problem in delta resetting...need your help... Thanks..
I have an ODS-1 which has target cube1, cube2, cube3....One week back a new target has been added as ODS-2....All complete data from ODS1 has been piped into ODS 2..(Note.. ODS2 has many more inputs from other cubes/ODS too)
NO issues till now....
I found a data problem in ODS-1 which got loaded 15 days back..... I have removed all 15 requests from cube1, cube2 and cube3... Now I am trying to reset the delta in ODS1...
I am getting the following error....Infoprovide ODS2 still contains request... Delete this first....
Since ODS2 has many other data alongwith ODS1... If I try deleting request from ODS2,, I need to clean it totally and redo... I dont want to do this...
Is there any way to disconnect this delta link between ODS1 - ODS2..... So that I will reload the data in ODS1 and populate into all targets...
Let me know your suggestions.... Thanks!
Regards
Ayyappan.VIs there any way to disconnect this delta link between ODS1 - ODS2..... So that I will reload the data in ODS1 and populate into all targets...
I dont think you can disconnect the link. just delete the requests originating from ODS1 in ODS2 and you can leave all other requests intact that are from other dataproviders and do a reinit. -
