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

Multiple usage of Source System is not possible with installed DMIS version on source

Hello folks!
I`ve got a problem trying to adjust the Data Replication to SAP BW (on HANA) using SAP LT Replication Server.
I`ve deleted one connection and after that I`m trying to create new one through Configuration & Monitoring Dashboard (transaction LTR) with the same source / target systems.
As result when on the second step (Specify Source System) I specify RFC destination of the source system it appears an error with text
"Multiple usage of Source System is not possible with installed DMIS version on source".
But there`s no any adjusted connection in system now..
Please, help me to understand how to fix that problem, I can`t find a solution

Hi,
When you say that you 'deleted one connection', did you delete the RFC connection or the SLT Configuration? If it is not a real multiple usage scenario, then deactivate the 'allow multiple usage' flag, else install the correct DMIS version on both SLT and source.
Thanks

Can we have SAP R/3 QAT system as source system for BI dev

HI ,
We are doing SAP BI implementation and in our company we have already SAP R/3
The problem is BI team is doing some development in BI DEV and they want to see some data.
But unfortunately we don't have much data in DEV enviornment.
So my question is can we have SAP R/3 QAT system as source system for BI dev.
Will there be any issues going forward.
As per my understanding technically source system is just an RFC connection for BI, so we can point it to QAT as well.
Do you guys foresee any issues in that?
Thanks,
Sumit

Hello Sumit,
What Arun said was what my concern was, he explained exactly the scenario that I faced, and that your BI team will face if you arrange your landscape as you said.
In my company for a while I had the BI Dev box connected to our ECC SND box.
It was done that way because of the lack of data in ECC Dev.
It worked, but it was definately not the best solution. Today we have BID and ECC Dev connected, BIQ and ECC Q, and BIP and ECC Prd. We do have data in teh attached ECC systems due to recent refreshes too, a large data set is very nice as it helps the BI team significantly.
That is the best way to arrange the landscape (and throw a BI SND to ECC SND for the true best practice!)
Thanks,
Nick

Question to assigning Source System for Activation

We want to assign source system for activation, before business content-InfoObject catalog activation. The steps as follows:
1.On the Data Warehousing Workbench: Business Content view from the menu choose Edit  Source System Assignment.->This step is ok, no question.
2. In the Choose source system by default? dialog box select the checkbox in the column Default assignment in the row containing the source systems you need to load data from.->Now we can see BI system as default call DEGCLNT500 displayed, in my case we only connect one R/3 system call DHHCLNT100 to BI system.
So, the question to that is shoud we select both R/3 source system and BW source system as default or just select R/3 source system as default and dis-select BW source system?
Which one should we choose, both or only R/3 source system?
Pls help, thanks!

Hi hi ni,
If what you are activating it's going to retrieve data only from R/3, then select R/3 and uncheck BW.
You can change this whenever you want, if in the future you need bw, before activating, you can change it.
This doesn't means where is going to get the data from, this is just to look for active (and replicated) datasources to connect to the business content you are activating.
Hope this helps.

Diego

Source System for Program RSIMPCURR

Hello,
I am using RSIMPCURR program for currency translation in my process chain.It was working fine in D but when I transport this to Q it's not working because the variant I am using for this is still using source system in for Dev. I need to change the source system for the Q system, Anyone knows how to change?
Also, I was trying to create variant manually in Q for the same program but it won't allow me to select source system. The Source system field is grayed out.
I appreciate anyone's help.
Thanks,
Peja

Hello,
You must create a variant for Program RSIMPCURR without specify the source system name and transport it.
After the transport, in the target destination, do RSA1 / Source systems / right click and choose transfer exchange rates. The Source system is already filled with the good value. You only have to complete the screen with the same attributes that you entered in the transported variant and save it with the same name.
Just do these operations in every BW target environments (Quality, Production,...)
I hope this will help you

BW as source system for 2 other BW systems

Hi
My BW1 system works as a source system for 2 other BW systems say BW2 & BW3.
I would like to configure infosources in BW1 system so that infosource A would be visible only from BW2 system & infosource B would be visible only form BW2 system.
Is it possible?
If YES how to do it?
Thanks a lot.
Pawel

Hi,
Hope you aware of Infosources interacts with Replicated Datasources.
As per your post, BW1 is a source system for BW2 and BW3.
So, you have to create Infosources in BW2 and BW3. So you have to replicate the datasources in BW2 and BW3.

Suman

Need Expert advice on choosing Source System for creating/maint Customers.

Hi Experts,
Iam on project where we have CRM,ECC(SD),FICA in the System Landscape.The client is currently using ECC(SD) Customer master for creating/maintainig Customer's.As we have CRM & FICA in this implementation, we are planning to propose that we use CRM as the source system for creating/maintaing Customers as Business Partners & Perform standard replication to the other system's in the landscape.
The client has has asked us to confirm if having CRM as the source is the Best practice in the industry when we have this three systems (CRM,FICA,ECC(SD)) Landscape.I thought to get some expert advice on this & see if any of you have a similar project experience & share some views on this CRM BP vs ECC(SD) Customer Master.
Thanks in advance!
Regards,
Naveen

Hi,
I believe it depends on your business senario.Here I can share some my experience for you.
CRM As Source System
Advantage:
1) Choosing CRM as source system ,you can create several roles of customer for tracking the presales process of customer，such as prospect ,sold to party ,customers ,also you can define the life cycle of your customer and control which life cycle of customer should be replicated to ECC and which one should not.
2) CRM can have more views of customer and customer defined field (EEWB fields) ,so if you choose CRM as Source it will be more convenient to create and fill in the all your user defined field .In other words ,choosing ECC as source you have to extend these field again in CRM .
3） easy to maintain customer relationship
Disadvantages：
1） Have to extend Company code view of Customer data, since CRM do not have these view ,it is just used for billing and integration with financial accounts.
2） have to extend some particular partner function of customer ,it is because of CRM it is only possible to create part of partner function automatically like SP ,BP when business partner is replicating to ECC.
ECC As the source
Oppositely， if you choose ECC as the source ,the advantage become disadvantage.
Advantage :
1) Can Easily to create customer's data of company code view
2) Can easily to assign any partner function to customer
To conclude， if you only need to create sales order in ECC ，I believe choosing ECC as Lead system is better, since you do not have to extend customer data and easily to integrate with FICO and SD.Howerver, if you are going to create a sales order from opportunity or quotation ,CRM is your best choice.

Multiple SAP R3 Source System in BI

Dear Gurus,
Here's my scenario,
I've SAP ECC Development Source System connected to my SAP BI Development Server system.
Now my Question is ,
1.We also have SAP ECC IDES system client 800 and therefore would like to connect this SAP ECC IDES system to our SAP BI Development System , because we need to do a pilot project for our prospective client and therefore we need the Dashboards and the reports created on the SAP ECC IDES system DATA.
So can I've two Source System in my SAP BI system ?? If yes , will it affect my present objects like InfoCube , Masterdata which I've already created with previous Source System ?
Regards,
-Neha

Hi,
So can I've two Source System in my SAP BI system ??
Yes its absolutely possible. In fact it is done in production systems as well, wherein some big organisations have multiple R/3 systems and only 1 BI system.
If yes , will it affect my present objects like InfoCube , Masterdata which I've already created with previous Source System ?
No it would not affect any of these. Your datatargets can handle the data from multiple systems. There is one rider on this.
The key fields in your datatargets should not have same value from different source systems, otherwise they would get overwritten by the new data records. e.g.
Suppose you have 2LIS_18_I0NOTIF datasource from both the systems getting loaded into same datatarget. If notification number from first system is 123 and from other system also 123, and this is the only keyfield in your DSO, one of them would get overwritten.
Similar would be the case for Master data loading as well. For master data, atleast you have a way around this. You can go for compounding with source system. This way system would differentiate the master data from different source system, even if their values are same.
Hope this was helpful

How to change the source system for just a datasource

Hi,
Our test/development BI system ( BI 7.0 Unicode ) is connected to our development system and to our test system, 1 BI system connected to 2 R/3 systems.
During some time, the test system won't be available so all datasources that point to the test system must be connected to the development system. In RSA1 is not possible to change the source system in a datasource: RSDS 057
'Creation of DataSources for SAP source system D30CLNT007 is not permitted' , same error trying to copy the datasource,.
Any idea about how to proceed ?
Regards,
Joan

Hi,
If I try to repliclate metadata in the datasource, message RSAR 051 appears: 'error when opening an RFC connection'. This error is expected because the logical system pointed in the datasource does not exist.
Is not possible to change the source system in datasource ( in RSA1 ) because the field is always greyed, also if I try to copy the datasource the message RSDS 057 appears.
Any idea about how to proceed ?

Joan

How to create source system for flat file loads

How do I create a source system to load flat file?
I have a screen that asks for the following:
Logical system name
Source system name
Type and release
What should I enter for these?
I am not Basis and Basis was supposed to set this up.

hi sam.
STEPS TO CREATE FLAT FILE SOURCE SYSTEM
step:1 select source systems under modeling in AWB.
step:2 select Source Systems root node.
           |---> context menu
               |--->create......
step:3 select your required source system Icon.
          (in your case it is PC Icon).
there it askes for a logical.......and source system name...
here u can specify any name of ur wish
for example:-
logical sys name --- PC_FF
source system name --- flat file source system*
*press Continue * button.
Observe the activation icon to confirm the successfull creation(_glowing lamp icon_ symbol)

'Error Occured in the Source System' for Non SAP system

Hi Gurus,
We have an Info Package which is getting the data from the Source System 'DOCP' and it has failed due to 'Error Occured in the Source System'.Since the source system is Non SAP system there is no option 'Replicate Data Sources'.So,First I activated the transfer rules by the program and ran the package again .But again the same error occured.
Please suggest me how to proceed for this error for Non SAP Systems?

Hi,
Check the RFC connection in SM59 and reactivate the source system again.
Hope this helps..
Thank you,

Error in the source system for fiscal year variant K4 Period 00

We are experiencing the following issue when loading data from module Flexible real estate RE-FX CASHFLOW CUBE OREFX_C06 Error in source system Fiscal year variant K4 is not defined for the period 00.

Hi,
You need to check in your source whether you have maintained Fiscal Yr Variant or not? Talk to you Functional person before you do the BI Extraction.
In Table T009B
You can check Fields
MANDAT - client
PERIV - Fiscal Year Variant
BDATJ - Posting date YYYY
BUMON - Posting date calendar month
Check Table T009B and see if you fiscal variant is maintained for all periods of Years (as per error its not). maintain the same in Source system and transfer Global settings in BW to copy the same into BW system.

2 clients of one ECC as a source system for BW

Hi Gurus,
we are asked by a customer to set up a new BW system, which will have 2 source systems, clients 300 and 400 of the same ECC. One client is ment for support team work and the other for project team. I understand that the dataflow is partly different (e.g transfer rules and datasources are source system dependent), but most of the dataflow (extractors, customer exits in ECC, infosources, update rules, cubes, etc) are the same. I am referring to 3.X dataflow as that is what we have mostly in the system, but we are on BI 7.0 already.
Do you see any advantages/disadvantages of this approach?
There are certainly some rules which have to be kept by such an approach (e.g. changing transfer rules for both source systems). What do you suggest, which rules should be kept? Would you do it differently? How?
Thank you for your valuable inpt,
Michal

Ahoj Michal,
your approach sounds feasible. You are already running BW in similar setup?
Yes you need to check and modify all your specific settings according data split from 2 clients: e.g. routines in InfoSources, Update Rules etc...
If I would do this differently? It depends on what purpose the data has in such a BW.
- Do they really need to analyze data from both clients?
- How the data model is setup? Do you have different data InfoProviders per client?
I would consider this for approach....
