Multiple source systems ?

Hi all,
What is the best possible answer/solution for the following scenario
If I am extracting same data(datasource) from multiple (say 3)R/3 source systems ie the datasources too are same for example 2lis_40_S600, how can we model the architecture in BW?
Should we have 3 infosources or just one. If one then how? Please let me know.
thanks

thanks Bhanu, you answered my question. Actually I need to decide on that, I mean I need to analyze all the char and keyfigures in these three source systems and figure this out.
Since all the data from three source systems is going to one infocube, I can do the transformations in transfer and update rules.
Another question about 0sourcesystem?
If I want to have 0sourcesystem in my infocube then I should have one infosource for all the three source systems right?
thanks.

SLT Replication for the same table from Multiple Source Systems

Hello,
With HANA 1.0 SP03, it is now possible to connect multiple source systems to the same SLT Replication server and from there on to the same schema in SAP HANA - does this mean same table as well? Or will it be different tables?
My doubt:
Consider i am replicating the information from KNA1 from 2 Source Systems - say SourceA and SourceB.
If I have different records in SourceA.KNA1 and SourceB.KNA1, i believe the records will be added during the replication and as a result, the final table has 2 different records.
Now, if the same record appears in the KNA1 tables from both the sources, the final table should hold only 1 record.
Also, if the same Customer's record is posted in both the systems with different values, it should add the records.
How does HANA have a check in this situation?
Please throw some light on this.

Hi Vishal,
i suggest you to take a look to SAP HANA SPS03 Master Guide. There is a comparison table for the three replication technologies available (see page 25).
For Multi-System Support, there are these values:
- Trigger-Based Replication (SLT Replication): Multiple source systems to multiple SAP HANA instances (one source system can be connected to one SAP HANA schema only)
So i think that in your case you should consider BO Data Services (losing real-time analytics capabilities of course).

Creating multiple source systems one logical system

Hi,
The requirement is to create two source systems using same logical name and different RFC connections to ECC?
We wanted to do some regular activities using one source system and some drill down activities using different source system.
I am getting error when I try to create second source system "source system already exist"
Please advice.
Thanks.

Hi,
I dont think it is possible to create multiple source systems in a sinle logical client. You have to create multiple clients and you can connect to BI system by different RFCs.
Hope this helps.....

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

Transformation issue while connecting multiple source system of same type..

Hi,
I'm working on APO-BW integration project. I want to connect BW QA & BW PROD to APO QA. I've already connected BW QA to APO QA & it is fetching data correctly. RFC part & other BASIS part is already taken care of. I've done export datasource (for mater data, cube etc) in BW PROD & replicated in APO QA. All BW PROD datasources are imported as RSDS (7.X) in APO QA.
Now my question is how to make sure the transformations will take source system as BW PROD too? I want 2 datasources (one from BW QA & other from BW PROD) to connect to same inforprovider in APO. I've transported 7.x datsource from APO DEV to APO QA environment along with transformations. In conversion of logical system names in APO QA I've given source system -BW DEV & target system - BW QA. So the transformation automatically takes data source as BW QA. It doesn't take source-system - BW DEV & target system - BW PROD as it conflicts previous setting.
Is only option that I need to manually maintain transformation from BW PROD datasource or there's another better alternative?

HI,
You are getting multiple IDOCs into BPM. But output you are getting one message right? IF so, your N:1 Mapping is not done correctly.
i.e your target message type should have occurence of 1..n and also the interface mapping. Closely obsever the N:1 mapping done in the BpmPatternCollectMerge.
Also go to SXMB_MONI->PE and check the Technical Details to make sure that, you are getting multiple IDOCs and you are executing the N:1 Transformation step correctly.
Also in the N:1 Mapping, check out the context you used. Make it root . Then test the mapping independently in the Integration Repository.
Hope it helps,

How to Load Master Data Text from Multiple Source Systems

Situation: Loading vendor master (text) from two systems. Some of the vendor keys/number are the same and so is the description. I understand that if I was loading Attributes, I could create another attribute such a source system id and compound it to 0Vendor. However, I don't believe you can do the same when loading text.
Question: So, how can I load duplicate vendor keys and description into BW using the *_TEXT datasource so they do not overwrite?
Thanks!

Hi,
Don't doubt, it'll work!
Sys ID as compound to 0Vendor.
If you doubt about predefined structure of the *_TEXT datasource and direct infosource, then use a flexible infosource. Maybe you'll have to derive the sys ID in a routine or a formula.
Best regards,
Eugene

Transaction Data from multiple source systems

Hi BW,
I want to load transaction data from two source systems: SQ1CLNT100 QA and SQ1CLNT200 Training client. into one BW system. What is the best practice, do I need to create another data structure or can I mix the data for QA and training in one data structure and separate them with authorisation?
Please someone should help me out with the best practice on this.
Thanx.

Hi Dan,
Do you mean use 0LOGSYS as authorisation relevant InfoObject?
Dont you think that if I copy bid from one source system and use it in another, the two bids will have the same GUID? if that is possible, then I may be faced with the problem of data override. Please advice further.
Regards.

Transport: Multiple Source Systems in QA

Hi gurus,
I have developed in BW Dev Transfer Rules starting from one R/3 Dev Source System.
Now I need to transport BW Dev settings into BW QA system, where I have 4 R/3 QA Source Systems.
In RSA1 --> Transport Connection --> Conversion (F8) I can introduce only one record to map Dev Source System with QA Source System.
How can I define that the single Dev Source System must be translated into several QA Source System ?
Is it possible ?
Thank you in advance.
Riccardo.

Hi,
Import 4 times by having Different conversion Each time.
And another thing:
Have you tried to create 4 Conversions at a time with same Source of source system and importing with these 4 conversions at a time. Even I too feel that it would not work. But you should try atleast once.

Multiple source system issue...

Hi,
We have two source system for BW Development and one source sytem for BWQ and BWP.
My query is: we have added two extra fields 0SOURCESYSTEM, 0FISCVARNT in the key fields to handle data from two different systems.
Do anyone have any more suggestion to handle such a scenario.
Suggestions will be highly appreciated.

Hi,
Incase if you are loading data from two sourcesytem ,you will have two data sources each representing one sourcesytem,then you can assign these to an infosurce with flexible update.
now you can craete two info packages for each source sytem and can load the data to the target
the steps may look something like this
replicate datasource1
replicate datasource2
create infosurce
assign datasource1 and datsource2 to infosurce
maintain transfer rules
under infosource
later create Ip for source1
create Ip for source2
crate target
create updaterules
map the infosoure to update rules
cheers,

How to load text data from multiple source systems.

Hello Gurus,
I am facing an issue of loading master data text into 0Material. I have loaded attribute data from 2 source systems. But i am not able load text data from the same 2 source systems as i am not able to see 0logsys in transfermation rules of 0MATERIAL.
Please gimme some inputs to proceed.
Thanks in advance
Peter

Hi,
I dont think that you need the source system info here, texts are mapped to attributs and attributs to source systems.
so try to load simply:
material key, text, lang (optional)
Hope it helps.

Using WAD with multiple source systems

Is there a way connect 2 BW sources to a dashboard built in WAD?
We have 2 BW systems in our global company. We want to create global metrics and the current strategy is to pull all data into 1 BW system and post.
There must be an easier way to pull a query from 1 BW system and another query from a 2nd system and post both results.
Without physically pushing the data into the backend.
Any ideas?
Thx,
Brandon

WAD won't be able to access from a different BW system other than the one you initiated the application from.
If you are using Visual Composer you could have done that, but another solution might be creating Remote Cube.

SPDD and SPAU Request from Multiple Source System (Dev and Quality) ??

Hi all,
We have one query related with SPDD and SPAU automatic adjustment during Upgrade.
We done SPDD in our Development systems and same is taken by SAPup during Quality Sytem PREPARE step from umauto.lst file.
But we adjusted some object in Quality System as the SPDD request from Develpopment does not able to adjust all the request. We created one request for the Same in Quality System and the that also got added to umauto.lst file.
Now during our during Mock run Upgrade, PREPARE ask to take only one system for SPDD request with following options
1. missing systems
2. Development (DEV)
3. Quality (QAS)
4. None
But we need both transport of SPDD from DEV and QAN to be imported to Mock run Systems till Production.
any suggestion to fix this ?

Hi,
Give the DEV requests for SPDD, and proceed. During DDIC_700 you will come across the DD objects which need to be corrected as you have done in QAS. here you need to open the system and correct them manually. Then only you should proceed. Be very carefull during this activity, as you may loose data if not done correctly.

Multiple R/3 Source systems for BW(3.5)

Hi,
A BW system being linked with multiple R/3 source systems , is a very common scenario. But could someone please help me out with a strategy doc / how -to etc. on the best possible way to install business content for multiple R/3 sources .
thanks

Hi Shurobhi,
This is a common scenario. there is not much difference between single source system and multiple source systems.
If you have data coming from 3 source systems you dont need to create 3 cubes and update seperately. you can update 3 source systems data into one single cube. For Example: FI AP Line Item data : You have source systems 1 2 and 3. you can use standard business content ODS and Cube to update FI AP data. Here first, init for source system 1 followed by delta for source system 1, then init for source system 2 followed by delta 2, finally init for 3 followed by delta 3. From here on you can load data to info cube in the above layer.
Thanks

Assignment of Source System in quality after transport

Hi Experts,
We have implemented the Inventory management standard flow in Development,
Now to tell you, we have multiple landscape over here,
Depending on the project, and the fesiblility for the client, the tranport layer is been decided,
But for sure we have multiple source system,
By multiple source system, i mean not the other components like R/3, SRM or APO,
but for R/3 itself we have multiple boxes at each layer,
Now when transported to quality,
the standard objects are reflecting after few errors corrected and re transports,
But the source system which it has picked for the BF BX and UM datasource is not that i require according to the transports landing for the R/3 developments,
AT DEVELOPMENT LAYER,
BW development is GDA, which is having the source system connection to development R/3 (GD0),
AT QUALITY
We have BW as EQ3,
For R/3 we have EQ0 and NR0,
All the transports have reached in the respective target quality system,
But the data sources are having source system connection to NR0 and not EQ0,
I want it to be EQ0 as the data lies over there.
How do i resolve this ?
Thanks and should be appricated for your efforts in helping.

Hi Daljeet,
You should set the Source system Conversion option in Transport Connection before Transporting the objects to QA and PRD.
You can do this using the button 'Conversion' next to the button 'Source System Assignment'. Here you can specify the Target source system name after the Transport.
If you want to change all the assignments from NR0 to EQ0, this article will be helpful for you.
