DW Side Work When the Sourcing System Gets Refreshed

Dear colleagues,
We currently have an ECC 6 Client as the sourcing system feeding data into our QAS BW 3.5 environment (basically Master data and very little transaction data at the moment). Due to the Master Data inconsistency of the sourcing client, it is decided to rebuild the ECC client plus complete Master Data reloading.
So, as a Basis person with limited BW knowledge, I am a little bit nervous from the BW side in terms of the procedure how to rebuild our QAS BW system. Here I have following questions for your experts:
1. Is there any standard procedure out there that I can follow in such a circumstance that I dont think is unique to us.
2. I believe I have to reload all the Master data once this has been done from the ECC side, do I have to delete all the Master data that have already been loaded into the BW and how should I do that?
3. With the very limited transaction data, will they be gone if I rerun the INIT process or I have to do things differently?
Thanks and regards,
Joshua Z.

Hi,
Not very sure about Refresh.
But this is what we follow when you go for an SP upgrade or maintenance on source.
As a standard procedure its better to drain all the deltas before going ahead. As a first step I think you will stop all transactions in ECC. Once done Start pulling delta loads repeatedly till it fetches zero records. then reschedule your V3 Jobs to a future date.
Then perform all this activities.
I dont think you have to delete MD as its overwritten the next time you load.
Is there a need for init if the previous init is still there?
Even in case you do I dont think you will lose any data. You always have an option of full repair to load any data from R3.
Refer.

Inbound idoc error in the source system

HI,experts
I manually configurate the idoc type ,message type ,etc between the BW system and r/3 source system when the automatic program encouters errors. And the communication between BW and source sysyem seems ok since the source system is activated successfully in BW side.
But when I check the inbound the idoc in source system after i triggerred a full load for the datasource 0FI_GL_4,an error occurs in the inbound process in R/3. There is no control information in the idoc which message type is RSRQST.
how can i figure this issue out ?could anyone help me ?

HI,ALL
Thanks for your replies and documents.
Now I find the problems lies in the error connection between R/3 and BW. IF the autoconfiguration is completelly correct , the table RSBASIDOC in both system should be added one record.But now when the source system is activated successfully ,the table in R/3 side has no entry while the BW side has one entry .juding from this ,there is no BW system connected to the R/3 ,which is proved when I fill the setup table for LO datasource an error message shows that there's no BW system is connected to the OLTP system.
How can i figure this issue out ?If I want to do an automatic configuration ,what shall I do ?

Hello All,
I found the solution for my particular situation!
When checking the runtime object for CLU4, an inconsistency in the runtime object popped up:
- the ABAP dictionary contains the field K5N1
- the DB dictionry contains the field name K5N01
This is a known and documented inconsistency, see note 902817 for the description.
BUT: the solution pointed out there is wrong! The note suggests to delete all content from the physical tables and then activate the table in SE14. This is not possible for cluster tables neither in SE14 nor in SE11.
This solution worked for me for both CLU4 and VER_CLUSTR:
- as the tables should be empty normally I dropped them in the database
- unlock the shadow instance with SAPup
- log on on to the shadow instance
- I then made some arbitrary change to the table definition in SE 11 (like adding a field). Make sure to maintain the size class also, otherwise the table won't be activated
- save the changes and activate the tables
- take back the previous change
- save and activate again
- lock the shadow instance
- restart the upgrade phase
Once the upgrade is done, check whether the physical table exists in the DB.
Hope this helps!
Regards,
Matthias.

How you remove the error depends on the error message.
And i did put in the period in the internal formatfor FROM and TO in the selection tab on the infopakand but I am still getting the same error.
And when i go into details it gives me " Error occurred in the data selection "
Please assist

Iam from Yemen we have CDMA carrier called Yemen mobile I bought an iPad from the US CDMA works with Verizon when I got to Yemen doesn't work with the carrier Yemen mobile and both carriers verizon and Yemen mobile work by the CDMA system don't know whey can anyone help me please..

A Verizon-model iPad can only work on CDMA with Verizon. You cannot use it with any other carrier. Apple, to my knowledge, has not released the iPad in Yemen, so there is no iPad you can use with any carrier there that works only on CDMA. You would need to find a GSM carrier and then get an unlocked GSM iPad.

Modeling the Data model when multiple source systems

Hi gurus,
i have a scenario where i am getting data from multiple source systems all R/3 but from different locatins.
my doubt is if i have to do reporting on the data available.
1. do i have to build seperate infocubes for each source systems or build seperate data designs for each source system .
2. How can i consolidate the different source sytems data into one and report sensibly as well as without loosing the source system identification.
thanks and regards
Neel

Hi all,
thanks for your focus, ya i am also thinking of have a flexible solution where in i can do it easily as well as we don't have much of complexcity, but wanted to try different options as well so that we can go for best one.
I thought of multiprovider at first when RafB suggested, and i agree with you as well Lilly, that data volume will be a problem, so keeping all this in view i want to build a solution where in it will be sensible as well as not confusing in reports ( i mean clear and readable reports)
[email protected]
please kindly forward any documents which might be helpful for me in this scenario
thanks and regards

When exactly source system recognizes the last delta is succesfull/failed.

When exactly does the source system recognizes the last delta is successful/failed?
Case -1: In logistic applications..
             What if I changed quality status to red for a successfully completed delta, and then requested new delta?
Case -2 : In Financial applications..
              When exactly BWOM2_TIMEST fields updated. I mean BW acknowledges to the delta load immediately saying it is successful or fail, or at the time when we request the next delta?
              What if I changed quality status to red for a successfully completed delta, and then requested new delta? It executes repeat or returns 0 records.

Hi,
Here's the explanation:
Scenario 1 -Logistics Delta
Sinc logistics delta comes from Delta Queue (RSA7) and IP takes daa from Delta queue so betwen RSA7 and BW, IDocs are transferred which sends messages for successful completon of extraction. As soon as extraction is over and a particular IDoc is sent to BW the BW marks the delta s successful. This happenes exactly when job is Source system completes Now if you make a successful delta as red then the IP identifies that last delta was not successful and requestes a repeat of last delta which again goes to RSA7 and picks the last delta and also the new deltawhich has come in RSA7. Note: RSA7 stores both new delta records and one last successful delta records(for delta repeat)
Scenario 2 - FI Delta
Sinc FI deltas are based on timestamp mechanism there are 2 possibilities:
a) The extraction fails while picking records from R/3 table (G/L, Ap and AR tables). In this case the timestamp isnot registered in BWOM2_TIMEST table and arepeat will work fine.
b) The load fails during procssing in BW (e.g update rules processing) and the job has completed in R/3 and has set the timestamp in table BWOM_TIMEST. In this case we will have to reetthe tmestamp and run the delta again.

I have deleted my private folder and do not have enough space to reinstall my operating system. How can i transfer files from my hard drive to an USB drive to free up space when the operating system isn't working. or do i need to erase disk?

i have deleted my private folder and do not have enough space to reinstall my operating system. How can i transfer files from my hard drive to an USB drive to free up space when the operating system isn't working. or do i need to erase disk through disk utilities without erasing data (but will it delete my programs such as photoshop, office, creative suite?

Connect the computer to another Mac and put it in FireWire Target Disk mode, or use the Disk Utility to clone the drive or image specific folders with the USB drive as the target. After you've copied off everything you want, you'll likely need to erase the drive and reinstall the applications.

Getting error like Information was stored in the source system

hai friends...
In Process chain, selecting particular info package delta and then selcting display messages am getting like...
"Information was stored in the source system"
data is not loading in to data targets....
Edited by: ganandkumar on Sep 15, 2010 10:24 AM

i am planning to load data in to PSA ...so i started and then it is showing like "
The last delta update was incorrect !
Therefore, no new delta update is possible.
You can cancel the request or:
Attempt to load the data of the last delta update again
so now i need to run this and i have to load data in PSA ...
suggest me friends...

R/3 connection to BIW - No Idocs arrived from the source system

Question,
Hi Team,
I have issues during loading attribute data from R/3 source system to BI,
I go to the path
Data Warehousing Workbench - Modeling window. In the DataSources view, my application component Group ##. On my DataSource i Create Info Package and save it,
Later I select the following options
Full Update = select
On the Processing tab page, select only PSA.
On the Schedule tab page, choose Start Data Load Immediately and start the data load.
Till here everything is in active version and saved, and connection to the source system is active and working fine.
However when I do loading I received following messages, what I observed in Monitor window,
Data was requested OK
Request still running
Diagnosis
No errors found. The current process has probably not finished yet.
System Response
The ALE inbox of BI is identical to the ALE outbox of the source system
or
the maximum wait time for this request has not yet been exceeded
or
the background job has not yet finished in the source system.
Current status
No Idocs arrived from the source system.
When I go to detail tab, under transfer section, I receive the following message
Data Package 1 : arrived in BW ; Processing : Selected number does not agree with transferred n
But when I actually go to PSA maintain section and select data and no of records, I can see the that data is loaded into PSA section,
But when I chose to run the transformation I donu2019t get data here,
Kindly help me to resolve this issue,

An error occured in the source system

My process chain has been doing FULL load for COPA data in a ODS. It failed today saying
Diagnosis
An error occurred in the source system.
System response
Caller 09 contains an error message.
Further analysis:

Refer to the error message.
When I click on indiv. Message tab I get "Job in source system terminated - Requests is set to red"
What should I do to resolve the problem.

For Source system R3 :
This particular problem "Job terminated in the source System" occurs when there are long running jobs in the backend.
In the monitor tab,

After logging into the source system, click execute
Check the status of the job i.e. active or failed.
Check the job log for the same.
If its " DBIF_SQL_..... " sort of error, then in this case, delete the request from the data target and reload again.
The load would be successful
Caller 09 error normally occurs when the source from which the datasource is picking up data may be in use on the R3 side.
Hope this helps!!!!!!!

Error in the Source system while data loding through Process Chain

Hi,
I am facing issue while data loading for certain extractors through Process chain. Load of 0BPM_WIHEAD, 0BP_LOGHIST, OBPM_OBJREL, 0BPM_DEADLINES(there are 2-3 more extractors) is getting failed daily with message Error occurred in the source system and if we repeat the same it is getting executed successfully.
Regards,
Javed

Hi..
It means that the extraction job is failing in the source system..
Please check the Job log in the source system --> Copy the request nimber --> In the source system go to SM37 --> Give * then the request number......execute --> Check the Job log..
Look there may be multiple reasons behind this....
1) Connection problem : Go to SM59 and test the connection, If you don't have the access in SM59...then go to RSA1 --> Source Systems --> Right click --> Connection Parameters --> Connection Test
2) Or may be work processes are not available and due to which jobs are failing due to time out...
In both the cases you can check with the Basis Team if they can suggest something....or you can change the process chain scheduling time if possible, and schedule it in such a time when less no of jobs are running..
Regards,
Debjani..
