Regarding Connecting Multiple BI Systems to single R3 System

Hi,
We have perform R3load based system copy of our BW Systems dev/qa/prod.
Now, we have D4D/D4T/D4P as one new BW Landscape
we have D2D/D2T/D2P as original BW Landscape
We have R8D/R8T/R1P as R3 Landscape.
Original BW Landscape is already connect to R3 in RSA1->Source Systems
Now I need to connect new BW Landscape to existing R3.
like D4D to R8D, D4T to R8T respectively.
I made new BWREMOTE user in these new BW Systems & when I try to delete
existing Source system that came as part of system copy. It says to
delete transfer rules,PSA etc also.
When I try creating a new source system from New BW to R3; it says
source system already exists.
Request you to kindly advise mechanism of same so that both bw systems
can connect to single R3 without any issues.
When I say restore on new bw system; It says "Connection DI is used in
R3_R8T10 Sourcesystem as a connection BW_D2T100 to BW". Delete this.
So, basically if I restore source system in D4T, It impacts existing
source system in D2T.
Thanks,
Sanjay

Hi Sanjay,
Instead of deleting exising source system, try to change logical systems and run BDLS job. It will fix problem.

Possibility of connecting multiple BW systems to single ECC system

Hi all,
I have a requirement in my company to connect multiple BW systems to single ECC system. Would like to confirm whether this may not be supported by all BW extractors in particular the delta mechanism?
For logistics extractor in ECC side in RSA7 it stores BW System as target which shows they support multiple BW systems as target, but for FI extractors which keeps delta timestamps in BWOM2_TIMEST table, it doesn't store the target system. I'm afraid if we connect multiple BW systems to single ECC system, some of the delta records might go to one BW system and some others go to the other BW system when we execute delta load in both BW systems.
Thank you very much in advance.
regards,
arie

Hi,
You can very well connect multiple BW systems to single ECC system and you will not miss any delta as well. In the source system for each delta data source a delta queue is maintained for each target system.
for e.g. I have two BW systems ABW and BBW connected to AEC system then for 0FI_AP_4 data source we will have DQ1_ABW and DQ2_BBW as two different delta queues (I am not following any naming conventions, actual names will be as per the target system logical name).
The settings maintained in BWOM2_TIMEST table are across the system and they define some global settings e.g. till what time the FI data should be extracted in BW system, for e.g. the time maintained is 2.00 AM then though you do extraction from multiple systems same data will be extracted till next time interval occurs.
In summery you can very well connect multiple BW systems to a single ECC system.

Durgesh.

Can we connect 2 ECC to a single PI system.

hi ,
can we connect 2 ECC to a single PI system. here we would be using proxies in the 2 ECC.
Is it possible to enable the SProxy for both systems.
EG: ECC1< -> PI (A)<-.>APO
ECC2<-->PI (A)<-.>APO
Regards,
Praveen K
Edited by: praveen kalwa on Jul 29, 2010 5:34 PM

Yes. you can connect 2 ECCs to a single PI system.
You have to create two entries for Proxy in sm59.
Please refer the below document for the proxy configuration.
(Put 'Proxy configuration in SAP XI' in Google Search & You will get a document from saptechnical.)
If everything goes fine, from both the ECC systems you can see the PI interfaces(Transaction : SPROXY) and implement them.

How can I connect multiple clients to a single client ?

I am currently developing an instant messaging program.I created a server and connected multiple clients to it by using thread logic.However I do not know how to connect multiple client to a single client.
What shall I do for that?Does anybody know a good tutorial or sample program?Or shall anybody explain me what I shall do for building the Instant Messaging part of my chat program?
Thank u in advance.

You may use UDP multicast socket. But since you are using the UDP protocol you might risk losing the data that you send since UDP does not guarantee the safe transfer of data.
Alternately, you might create a server that allows multiple client to connect to it whose connection Socket objects are then stored in a Vector <Socket> object. The server then sends back data to the connected client about the other clients connected to it. Now when the client wants to send data (like an IM) to another connected client, it has to send a request to the server specifying the client login name and the server in turn streams that particular client's Address and Port to the requesting client. The requesting client then initiates the connection with the other client and then starts a conversation. One more thing, when the client communicates it needs to send information to the server like the name by which it likes to be referenced. In this scenario the server acts like a central repository for clients to query the existence of other clients in the chat room. Each client here runs a thread that listens to incoming connections and when a connection is established, may be opens a IM window or something.
The third option is to make the server to relay the information from one client to another. Like say, I'm connected to whoopy server and i want to send "Hello" to jackson, then i send the message (ie, Hello) along with the name of the client to which i wish to send it to (ie, jackson). The server then performs a lookup in its Vector <Socket> object and then initiates a connection with jackson and sends the information. However, this method is pretty costly in that you will be wasting a lot of processing behind the server.

P.s. If you stumble upon any other brilliant ideas let me know.

Connecting multiple ECC Clients on same ECC system to BW system(s)

Hello.
We are considering connecting our Dev BW system to multiple clients on the same Dev ECC system. This connection would be for a limited time. We are wondering what the effect would be on the ECC system after we 'disconnect' our BW system from one of the clients.
Another thing we are considering is to create a seperate BW sandbox system and to connect that to a client on our Dev ECC system. The Dev ECC system will, at the same time, have a connection to a client on our existing Dev BW system. For example, having DEVBWcnlt100 -> DEVECCclnt100 and SNDBWclnt200 -> DEVECCclnt200 where DEVECC is a system and DEVBW and SNDBW are systems of their own. Our Sandbox BW system will have a limited life and at some point be taken down and no longer be a valid source system for the DEVECC system. We are concerned about what the impact would be to the DEV ECC system's client independent data once the Sandbox BW system is disconnected and taken down permenantly. Is 'residual' client independent data something we need to be concerned about? Is having two different BW systems connected to ECC clients on the same ECC systems a 'bad practice'? Any and all comments are welcome as we have not yet acted on our ideas yet.
Thanks very much for whatever comments you might provide,
Geoff.

We are considering connecting our Dev BW system to multiple clients on the same Dev ECC system. This connection would be for a limited time. We are wondering what the effect would be on the ECC system after we 'disconnect' our BW system from one of the clients.
No impact on the BW system. The only thing that you will have to take care of is that any process chains which fetch data from this DEV ECC system should not be put on periodic cycle because after disconnecting the ECC system, these would start failing.
Another thing we are considering is to create a seperate BW sandbox system and to connect that to a client on our Dev ECC system. The Dev ECC system will, at the same time, have a connection to a client on our existing Dev BW system. For example, having DEVBWcnlt100 -> DEVECCclnt100 and SNDBWclnt200 -> DEVECCclnt200 where DEVECC is a system and DEVBW and SNDBW are systems of their own.

We are concerned about what the impact would be to the DEV ECC system's client independent data once the Sandbox BW system is disconnected and taken down permenantly. Is 'residual' client independent data something we need to be concerned about?
Again no impact on ECC system. As for the client connected earlier to sandbox system, just clear all the queues in RSA7, LBWQ
Is having two different BW systems connected to ECC clients on the same ECC systems a 'bad practice'?
No its not at all a bad practice

Multi-Processor Systems vs Single Processor systems

In general, is it better to run Weblogic on a fast single processor system
or on a multi-processor system where the individual cpus are less powerful?
I am assuming that the platforms are WINTEL and all other things (memory,
disk channels etc) are equal.
What are the licensing implications of one philosophy over the other?

I am assuming that the platforms are WINTEL and all other things (memory,

your client load.
I'd suggest that you run a load test against both systems and compare
the results.

Connecting multiple C4C tenants to same HCI system

Hello Experts,
Please note that we already have a Cloud For Customer (C4C) system connected to our HCI system which is connected to our ERP system.
How can I connect another new C4C system to the same HCI system as above which connects to the same ERP backend system QEC.
Would this new C4C system use the same tenant/worker nodes or will there be a separate new one be created for this new C4C system.
Please let us know what is the best possible approach.
Regards
Indrasish

Hi Indrasish
THere are probably a couple of options. One is to adjust HCI to send to two receivers. We'd need to look more at how the data needs to flow.
The other is to have duplicate setup -the following is what we do for a training environment with mutliple C4C's connected to one HCI and one ERP:
* C4C tenants have the communication system for ERP that points to HCI
* If you will have the same iflow from the ERP to each tenant, e.g. material master from ERP to C4C tenant1, material master from ERP to C4C tenant 2 - then you need to do the following:
*** HCI import the iflow, rename the iflow and the manifest. When you deploy you will also need a unique name. for example: /cxf/ERP/COD/ADR3MAS03_TR99 - deploy the service with the extension
*** in ERP in the RFC destination to HCI you need to also adjust the RFC dest, for example, /cxf/ERP/COD/ADR3MAS03_TR99 so that the deployed iflow name matches.
*** the deployed iflow also has the updated URL for the related C4C tenant.
In this situation you have duplicate iflow for each C4C tenant. The other option is to use one iflow and have two receivers, this would assume everything always goes to both tenants.
Does this make sense or is it confusing?

Regarding reading multiple records into a single internal table..

hi experts,
Need your help, i have a requirement like this.
i will have a input file like this
D 123   Suresh    12/01/2008
E ven   sha         5432
E ven   sha       5432
D 153   Sachin    11/01/2008
E ven   sha      5432
Now all i need to consider from D to E (i.e., before next D) as a single record and i need to preare a separate excel,
So that E records can be max 9. So we cant expect this will be always 2 or 3 or 4.
So how can i do this upload and process..
give some idea.
Thanks,
Suresh

Hi,
Once you transfer the values from input file to internal table.
loop through all records of internal table .
check the first letter using offset
e.g if Itab-field+0(1) = 'D'
       elseif Itab-field+0(1) = 'E'.
       endif.
     Populate the work area of internal table until you find the next 'D' once you find 'D' again ...append the work area to internal table......clear work area.

Two BW systems to single source system

Hi,
I have created sandbox and copied BW production now its BWQ.
Now we want to connect BWQ to R/3 PRD as source system. But from RSA1 when I try to restore PRD it will delete the connection to BWP and creates to BWQ. But I want both connections to work.
How this canbe done?

hi,
not sure, try check following links, in r/3 side transaction sbiw
http://help.sap.com/saphelp_nw04s/helpdata/en/7a/27bcf087c7464db8b95eaa717b6e6a/content.htm

i have no access to system now, not sure whether there is authorization object for datasource in bw side.

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.

Multiple iPhones on a single iTunes account

My girlfriend and I share a computer for our iTunes music and such for my iPhone and her iPod. She is getting an iPhone soon so I am wondering if she will need to make her own iTunes accout or if we will still be able to share the same music and everything on a single iTunes account? If she does need her own iTunes account for her iPhone, will she be able to access the music we have downloaded from my account on the same computer?

My question is a bit different. I have not yet been able to wean my wife off her dying Dell. While she has iTunes on it sync fails so she has not backed up her 3GS phone in ages. She has different music, pictures, and apps than I do, and we do not want to share these. So I want to sync her phone (and iPad as well) to my Macbook Pro, but keeping things separate.The responses and Apple material regarding syncing multiple phones to a single Mac talk about shared music and media libraries and do not seem to talk about apps.
I'm afraid if I try to sync her devices to my iTunes it will wipe out her apps and media. Can anyone confirm or refute this?
Thanks

Connecting multiple CRM systems to one backend R/3 and vice versa

Hello experts
Can you tell me whether it is advisable to connect 2 CRM systems to a single backend R/3 and vice versa? Is it recommended by SAP? I require some notes or docs on this. I got some notes on this forum but they are all Internal ones which I am unable to see.
Please help!
Warm Regards
Debolina

Hi,
Though SAP does not recommend connecting multiple systems to one ECC backend. But still it has designed a procedure to achieve this.
Here is the excerpts of the steps required.
1. Execute report MCRM_SETTINGS for each CRM system connected to the ERP
system.
2. Check the entries of the table CRMRFCPAR of the connected ERP system:
The field REM_LOGSYS should be filled for every entry marked with
u2018Created by the MCRM reportu2019.
3. Activate the corresponding consumers in the table CRMCONSUM
(transaction SM30).
4. Internal and external number ranges for Business Partners have to be aligned
manually.
Hope it helps you!!!!
Good Luck.

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,
