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 ?

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

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

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

Impact of upgrade of SAP R3 source system on BW system

Hi Experts,
Could you please help me to list down the impacts on BW system due to upgrade of SAP R3 source system?
[1] Is there any impact if R3 is upgraded to Unicode restricted version from a version where Unicode restriction was not mandatory?
[2] With respect to delta loads what will be the threat?
[3] With respect to Business contents modifications by SAP's new upgraded version, can be there be any threat?
Any inputs will be appreciated... Thanks in advance!
Regards, Somenath

Please specify which version of BW u r using.
A direct upgrade to ECC6.0 is possible from a minimum lower version of R/3 3.1i and not below that and coming to BW an upgrade to BI 7.0 is possible from a minimum lower version of BW 3.0B and not below that.
The compatibilty is possible with an addition of some Plug -In's or Patches.
There will not be much of problem,

Multiple R/3 source systems to one BI system

Hi Friends,
We are planning to split our SAP R/3 Into Different Servers...one each for different companies.
At present we have only one source R/3 System from where we are getting data to BI.
If we split it into different source system................can we load date to BI system simultaneously from different source systems.
or we have to schedule one after one....
Please advice me........
what are prerequisites we have to take care if we go for different source systems.
Thanks&Regards
Anand

Hi,
As the source systems would be different, you have to maintain the master data into each system seperately and that should be consistent. Lets we take an example for an employee. In one system, one employee is active from say 1 Jan 2009 to till 31 Jan 2009 and the same employee is active into another system say from 1 Jan 2009 to till 31 Mar 2009, then It will create problem while loading the master and transaction data from different source systems and hence the reporting would also not show correct results.
There is no other option except to maintain the consistent master data into all the systems.
Cheers...

New transactions for BW in SAP ECC source system

Hi experts,
I need to know if in SAP ECC 6.0 there is someones transactions news or changed for datasources manages.
For example:
For create/Modify generic datasource
Activate LIS* datasources
rsa5 Functionality because the hierarchy has differents name; before the hierarchy began with SAP hierarchy, now is Not connected...
Any information about with ECC 6.0 and integration with BI 7: transactions list and migration I will receive very good.
Thank you very much.
Regards,
Jeysi Ascanio

Basically, the same transactions are used. I don´t see a different treatment until now.

ST22 information at Source System.

Hi ,
        mine is a webservice to PI to proxy scenerio. I prefer a synchronous process, but I have the choice of making it asynchronous also.
   However my requirement is , if information sent from webservice reaches sap abap proxy through Pi and then throws a short dump in ST22 of sap, then source system i.e. webservice will never get to know about the same. Is there any option to check it/ tracce it??
Experts, your comments pls .
Regards,
Arnab.

Hi Raghu ,
                     your concept appreciated. I planned this long back. But there was a catch. I noticed in ST22 , most of the short dumps have an exception , but there are a few, which dont have exception. Strange but true. You know what, ultimately, we are moving into this type of coding, but the hitch lies in the mind , if there is a dump, without an exception , and the cllient is unaware of the same , we miss the business !!
   Thanks and Regards,
Arnab ,

How to recover a datasource from source system

Dear Experts,
i am trying to find a datasource(0PS_PRJTYPE_ATTR) in the source system. For some reason, I could only find the text one, not the attribute one. I checked in RSA5, RSA6 and RSA2. I couldn't find it.
What are the possible ways to recover the datasource, not sure if someone has deleted it.
Its really urgent, Please guide me.
Regards
Shanthi

Hi,
The same should be available in the source system (DEV), Surprising how / why the same is available in BW system.
I checked the SAP ERP source system to which I have an access and the same is not available in the source system not in the BW system
My sugession is to go for a generic datasource after identifying the table with the help of functional consultant.

Establishing a Source system

Hi all,
Can i connect a Sandbox system as a source system to BW dev system? I wasnt sure if i would connect sandbox or not.
Thanks,
Mav.

Hi,
Yes. Are you planning to have multiple R/3 source systems for one BW dev. system. If so, you might want to search this forum for "0logsys" and "0soursystem". There are some interesting discussions on this topic.
Hope it helps,

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).

SAP Note Number: 852443 | Runtime Error MESSAGE_TYPE_X in Data Source over HANA Source System

Hi,
I am facing an issue for Inconsistency in Delta extraction due to a Init Request Mismatch.
I found out an SAP Note 852443 for the same and it provided me with a workaround solution for the same.
But , this Issue is frequently reappearing for the same Data Source and I need to find a permanent fix/solution for the same.
Kindly help me in this.
Thanks,
Vimarsh

Hi.....
I have gone through the SAP note......what I have understood I will explain you....
1) You need to compare the Init request (ex : REQU_44H2K09BTG5799G2JXCORI1O5) in both BW and R/3 side....both should be same......
In the R/3 side the value of the field : RNR of the table :RSSDLINIT should match with the value of the field : INITRNR of the table ROOSPRMSC in the R/3 side.....
2) If there are NO entries in the RSSDLINIT table in BW, use transaction RSA7 to delete the delta queue for this DataSource/BW application combination in the source system (OLTP).........this step is very simple.......
3) But the confusion arrise when value is there in the table RSSDLINIT in the BW side.......then check the same Request number in the table ROOSPRMSF and ROOSPRMSC tables with the INITRNR field.
If, in the ROOSPRMSF and ROOSPRMSC tables for your DataSource source system combination, there are more entries with different INITRNR numbers...............it means if the value doesn't match or multiple values are there then also same solution ...........i.e...........use transaction RSA7 in an OLTP source system to delete all entries ...............then use the Program : RSSM_OLTP_INIT_DELTA_UPDATE and then delete all init selections in the 'Scheduler/Init selections in the source system' menu in the InfoPackage.......
4) But if it is a DataMart datasource that is a Export Dtasource then the solution is different.........starting with 8
But I don't want to confuse you.........first check whether is is a Export Datasource or not.....

Debjani.....

Multiple DataTargets in a BI 7.0 System to One DataSource in Source System

Currently, I do not have access to BI 7.0 system. I am wondering whether it is possible to connect MULTIPLE DataTargets of a single BI 7.0 system to ONE DataSource in the source system? I have searched the forum, but I couldn't find relevant posts. If I am not wrong, until BW 3.5, once a DataSource is assigned to an InfoSource, it can not be assigned to any other InfoSource of the same BW system. I have heard that this has changed in BI 7.0 with the new DataFlow concept.
The current requirement is that multiple DataTargets of a single BI system need to get DELTA data from the same DataSource in the source system. If this is technically possible in BI 7.0, should the source system also support such an assignment (since the DELTA load timestamps are maintained in the source system)? What source systems currently support this feature, if any? What are the appropriate tables in the source system that I need to look at to do further investigation?
All the useful inputs regarding these questions will be rewarded with points. Let me know if you need any further clarification of the requirement. Thanks!
Sameer

Hi Sameer,
But since there is only one transformation between the PSA and DataTarget, all the data (irrespective of the indicator) will flow through unless I filter on the "planning stage" indicator
You can create one transformation between Datasource and ONE DataTarget. But in your case, you have TWO datatargets. So you have to create two DTP's which can have diffrent filter parameters.
You can fill two different targets ( cube1: before manual update, cube2: after manual update) using your datasource.
For this, you need to create two transformation. Keep in mind, everytime you create a transformation you must create a DTP for data movement.
So you will have:
DS1 -- TRANS1-- DTP1 --Cube1
DS1 -- TRANS2DTP2Cube 2
In DTP1 set filter for indicator :X and DTP2 set filter for indicator :Y. Both DTP1 and DTP2 should work in delta mode.
I would suggest you to create one initialization for your DS1. if it is not possible create two infopackages for two initializations. I suppose you have the indicator in selection parameters of infopackages.

Create SAP Source System Failed

Hi all,
We are using NetWeaver 2004s BI and try to connect to ECC 5.0. I tried to create SAP source system but got error message saying "RFC user logon failed". When I check RFC destination in ECC 5.0 for BI, the test connection is ok, but the remote logon will pop up another logon screen asking for id and password. I am pretty sure that the id and password in RFC destination is correct. The RFC destination in BI is ok. Can you help me out with this? Thanks a lot in advance.

Hi,
Check the Default Logon <b>Client</b> for ECC 5.0
and verifiy that the User is in the Same Client
Each RFC destination has a mapped user for specific Client..Check the Client and User in the same client

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,
