Hi
see page 63. it is possible.
define backend systems in spro and record all your ecc systems and create a distribution model fpr bbpiv message in srm and distibute to all backend systems.

WD Exception when pointing ESS Travel & Expense to multiple backend systems

Hi All,
I have a query regarding ESS Travel Management pointing to multiple backend systems.
ESS MSS is installed on a single portal(Portal1).
ESS MSS is currently pointing to Backend System1. The requirement is that ESS Travel from Portal1 should point to various multiple Backend Systems therefore making ESS Travel region-specific.
Is this possible? and if so what are the pros and cons?
This is what I have attempted:
1. Followed the documentation from "Multiple Back End Support for the Adaptive RFC Model" [http://help.sap.com/saphelp_nw70/helpdata/en/af/84a34098022a54e10000000a1550b0/frameset.htm]
Therefore, I created 2 JCOs namely: SAP_R3_Travel_R1 and SAP_R3_Travel_MetaData_R1 pointing to Backend Sytem 2. SSO and JCO tests successfully.
2. On the iview properties for ESS Travel & Expenses, I added the following to the Application Parameters: sap-wd-arfc-useSys=SAP_R3_Travel:_R1&sap-wd-arfc-useSys=SAP_R3_Travel_MetaData:_R1
3. I additionally created a system in the Portal under System Configuration pointing to Backend System2 and adding the SAP_R3_Travel_R1 as the default System Alias. Do I need to add SAP_ITS_XSS and SAP_WebDynpro_XSS system alias, if so how since it is seeing as redundant because it is added in the system I created for Backend System1.
4. I then tested one of the ESS Travel & Expenses iviews. I have the following error:
Accessing System XYZ is not possible because RFC Metadata was retrieved using System ABC. Please assure you have configured the RFC Connections properly. A Server restart may be necessary!
Your help is appreciated.
Thanks.

Find exact RFC Destination for Multiple backend Systems In SAP Gateway

Hi Gateway developers,
I have requirement,if gateway hub system has multiple backend systems( for example two backend systems: ECC and SRM ) then how hub system can get the suitable backend alias for exact entity collection..
Here i have developed two entities one entity regards: ECC and second one regards SRM system..within this when I run the service it is always taking any of the same alias for both the collections..
Can you please suggest me..
Thanks
Sreenivas Pachva

Hi Srinivas,
You can add the respective system Alias Name: Like logical system name in your URI also.
Example:
/sap/Service Name;mo=ECCCLNT210/zentity1?Customer1='0001'
/sap/Service Name;mo=SRMCLNT400/zentity2?Customer2='ABCD'
May this help you.
Thanks,

Unable to define connector for multiple backend systems in BRM

Hi,
I am on GRCFND_A V.11 and SP04
I have multiple backend systems integrated with GRC box. So far I was using one backend connector as default one for role maintenance but it is not feasible if you have to create roles in variuos backend connected systems. I know one way to do so, i can keep changing the default connectors whenever i need to create roles but that is obviously not at all the onw any one would like to go with.
So, I tried to create unique connector groups for every individul backend connectors. But the issue is, the moment i assign the backend connector to the respective connector groups, the same gets reflected to other connector groups as well. So, whenever i either add or delete some of the connectors to any connector groups it gets modified/changed from all of the connector groups.
These are the backend connectors where i have to create roles from BRM whenever needed.
These are the connector groups:
I followed to the ink: GRC AC 10 BRM: Default Connectors with Multiple Back-end R/3 Systems , which is the same as mine issue, but not able to come to the solution point.
would appreciate for your quick response.
Thanks,
Ameet

Could anyone suggest solution to the above mentioned issue please?

Programmatic access to multiple backend systems using adaptive RFC

Hello,
The following link http://help.sap.com/saphelp_nw04/helpdata/en/af/84a34098022a54e10000000a1550b0/content.htm talks about the support to map multiple backend systems by specifying the backend system as URL parameters in a webdynpro application.
For example:
http://<hostname>:<port>/webdynpro/dispatcher/local/ESSProject/ESSApp?
sap.wdarfc.useSys=WD_MODELDATA_DEST:ABC&
sap.wdarfc.useSys=WD_RFC_METADATA_DEST:ABC
Is it possible to programmatically change the backend systems the application connects to? in other words can a single application while executing connect to different backend systems by dynamically changing the model parameters?
(This should be possible without the portal in the picture)
Cheers,
Praveen

Multiple backend systems for business package ESS/MSS

Hi,
I would like to know whether there is a smart solution for connecting the business package ESS/MSS with multiple backend systems (up to 10 systems).
I am aware of the possibility using parameter "sap-wd-arfc-useSys", but this implies, that content needs to be duplicated n-times in order to be able to maintain the Jco destination suffix.
Any hint, also for custom built solutions are very welcome!
Best regards,

UoM issue due to multiple backend systems

Hi All,
We have multiple backend systems hooked up with the SRM system. One issue that we have is that many of the UoMs are different in the backend systems. For example, for THOUSANDS, we have TH and THO in different systems. As part of optimization we intend to include only 1 entry per UoM in SRM box.
The problem is if we put TH as the unit, then if it is chosen by a user linked to the backend system that does not have this Commercial unit, then the Shopping Cart fails when trying to create a follow-on document.
Any advice how we can get this resolved will be greatly appreciated.
Best Regards
Gaurav

Hi Gaurav,
Common problem when using multiple back-ends, which can be resolved rather easily. The best way to solve this is by a business change. That isu2026. synchronize the use of the UoMu2019s throughout the organization. This would be the most elegant solution. All back-ends will then have the same valueu2019s in their respective CUNI tables.
Off course the feasibility of this will depend on your organizational structure and the hitting the u2018right stringsu2019 in order to get every one to understand the importance of this.
As a back-up an other solution would be to create a Z-table which will translate the UoM used in the SRM system to the corresponding UoM in the respective back-endsu2026.. The table will have three columns. u2018SRM UoMu2019 u2013 u2018Back-end Systemu2019 u2013 Back-end UoM. Depending on the implementation scenario U use, you can have the interface to the back-end carry out the translation. For this you can use the available Badiu2019s: BBP_CREATE_BE_PO_NEW, BBP_CREATE_BE_RQ_NEW, BBP_CREATE_BE_RS_NEW
Downside of this solution will be the extra maintenance effort for the Z-table. Best choice in my perspective would be the business change.

One ECC Connected to multiple CRM systems

Hello,
We have a scenario where we have single R/3 system (ECC) connected to multiple CRM systems. I would be obliged if someone can send me some documentation on tht.
Also if we are creating an order in ECC, two queues are generated which I think is wrong. Can someone give me some advice on this.
Thanks & Regards
Priyanka

Hello Pratik,
I would define two different systems in ECC. In such a case, if say I create one material in R/3 (ECC) then should it generate two diffrent queues for flow to CRM.
Also if say the CRM Release etc for the two systems connected to one R/3 are not the same, then how do i take care of the entries in the ECC Config tables for replication i.e CRMFILTAB, CRMCONSUM, CRMPAROLTP etc.
And how does the ECC system identify what settings it has to take for what CRM system and what queues have to be generated? What are the queues to be registered in CRM and ECC in such a case.
Would be obliged if you can give me a more detailed advice.

Multiple ESS's in one Portal connected to different backend systems?

Hi,
We have two backend systems installed.
We have one portal.
We want to create a second copy of the ESS Portal content connected to the the second backend.
Datawise this is not a problem.
But what about the JCo's and the Homepage Framework?
The WebDympro application seems to look for two specific JCo (for example SAP_R3_HumanResources and ...MetaData) and then both copies of ESS want to use this. Is it not possible to have each copy of ESS use it own JCo's and connect to its own backend system for the Homepage Frameworks?
Thanks,
Adriaan

Adriaan,
Its NOT possible to even talk to different clients in same backend system because you cannot duplicate the JCos and while creating them you need to specify the system and client details.
Also it uses a system alias which also has to be unique.
Per my knowledge one portal instance can talk to only backend client and to talk to another backend / client you will need to create a new instance within the Portal.
This [help|http://help.sap.com/saphelp_nw2004s/helpdata/en/82/76a2406546ba15e10000000a1550b0/frameset.htm] talks sometihng on multiple backend support. I am not much aware about it but see if it helps you.

User authantication error when we try to connect to a backend system

Hi,
We have a stand alone webdynpro application where in we are calling some rfc function modules. We have imported the models using jco connection in a development system by providing the system/user info. When we deploy and run the application in the development system the application works fine. But when we deploy the application in different test systems it fails with user authantication error while triggering those rfc function modules. Can any one help us how we can identify the problem?
We basically dont know with what system/user information its trying to connect to back end.
Kind Regards,
Prakash

Hi Prakash,
THere can be Multiple reasons for this problem
1.if you are using JCO connections with UID/Password authomtication,make sure that Connection is working properly by testing it in Web dynpro console administrator.
2.if you are using SSO authontication mechanism in your JCO Connections,make sure that you have UID in the back end system(BAckend Quality system) and your portal system is connected to Backend quality sytems using SSO.
hope this helps

How to connect SAP R/3- System with SAP NetWeaver Portal (2004s)?

Hello to all,
sorry, can someone help me? How can I connect SAP R/3- System with SAP NetWeaver Portal (2004s)?
Thanks and regards,
Galyna

Hi,
In previous link contain this info
This describes how to connect an SAP R/3 system to SAP NetWeaver Portal using an iView
1)      Go to System Administration
2)      Go to System Configuration
3)      Go to Portal Content (Right Side Panel), open that folder.
4)      Right Click on Portal Content, a Panel is displayed select "System (from Template)".
5)      That will display a new view on right side, now select "SAP system using dedicated application server" from
the existing templates. (Other templates are possible - for example, load balanced or through a SAProuter connection string).
For this exercise, we'll use the simplest type.
6)      Choose next
7)      Give the System Name and System Id (which are mandatory fields) incase you want to give any brief notes
about the system then give them in the "Description" field.
8)      Open the Newly Created System.
9)      Now when you want to create a New System, you have to fill four Properties they are:
"Connector" - contains basic connectivty details
"Internet transaction Server (ITS) - if you wish to use SAPGUI for HTML and/or IACs",
"Web Application Server" - if you wish to access BSPs and/or Web Dynpro for ABAP and
"User Management".
You also need at least one "System Alias" has to be defined from the Display drop down menu.
Make sure you have set end user access in the Permissions drop down menu to all users who need to access the system
10) Select "Connector" property, now fill the required fields such as:
a)      Application Host (should be fully qualified hostname) - Give the R/3 "Application Name",
which can be obtained from the SAP Logon Pad (check what R/3 system you are using, right click on it , go to the properties,
it will open a window which has the Application Server Name.
b)      Logical System Name - Give the logical name as defined in the backend system
c)      SAP Client - Check the Client in the backend system and give the appropriate number (3 digits)
d)      SAP System ID(SID)* - Check the R/3 properties and give the check for System ID
e)      System Type* - Since we are connecting to R/3, select SAP_R3 system.
f)       System Number - This is a two digit number that you can find in the SAP Logon Pad
11) Select "Internet transaction Server (ITS)" property, now fill the required fields like
a)      ITS Description à Give some Description
b)      ITS Host Name - Same as "Application Host" of R/3 (when integrated ITS) and should be attached with the
port number of ITS Server (to get port number detailed description is given below). ex: hostname : port number
c)      ITS Path - To get the path along with the port number you have to Log on to R/3 system. Use the
Transaction Code "SICF", it opens a new window go to:
      default_host -> sap -> bc -> gui -> sap -> its -> webgui -> SAP GUI for HTML -> right click on
that and click "Test Service'. This will open a new window, on the address bar you will find the "port number", and
the path something like (/sap/bc/gui/sap/its/webgui). Use the path after the port number.
d)      ITS Protocol - There are two protocols "http" & "https", select the appropriate protocol which is
visible when you opened "Test Service" window.
12) Select "Web Application Server" property , now fill the required fields like
a)      Web AS Description -> Give some Description
b)      Web AS Host Name - same as ITS Host Name
c)      Web AS Path - usually /sap/bc/bsp/sapd)*
Web AS Protocol - should be same as the ITS Protocol.
13)   Select "User Management" property, now fill the required fields like
a)      Authentication Ticket Type - Since we are not using SSO leave the field
empty i.e. put in select mode. (Please note that longer term you will probably want to use SSO)
b)      Logon Method - Select UIDPW.
c)      User Mapping Type - In case you have administration rights then you choose "admin" or in case you
just have user rights then choose "user", better go for "admin/user".
14)   Since all the required fields are filled appropriately now create a System Alias name, this can be done by following steps:
a) go to Display -> Select "System Aliases" give some Alias Name, let's call it "SAP_R/3"
15) Now that System is created we have to create a iView which will display the given Transaction Code.
16) Go To "Content Administration".
17) Go To "Portal Content".
18) Go to Portal Content (Right Side Panel), open that folder
19) Right Click on Portal Content, a Panel is displayed select "New" -> iView
20) Select iView template, click next
21) Select "SAP Transaction iView" from the list of templates available. Click next.
22) Give the iView name and iView ID. Incase you want to give any brief notes about the iView then give it in "Description" field. Click next
23)   Select "SAP GUI for HTML" radio button. Click next
24) Now select the system which you have create "SAP_R/3", give some Transaction Code, say SE12 (Dictionary Display). Click next and Finish.
25) Now Preview the iView
26) You will see a new Window where in SE12 Dictionary Display window is displayed.

Connect to a backend system with the BI connector via Visual Composer

Hi all,
I set up a system landscape on my notebook with the NW2004s ABAP as NSP and with the NW2004s JAVA SP7 as J2E. Both systems are integrated in the SLD, this is set up. Furthermore I installed a BI system alias as NSP_XMLA in the portal with the URL for the backend system: http://localhost:8000/sap/bw/xml/soap/xmla.
I have the same user on portal and backend system NSP. Both have admin previleges.
When I try to logon to the backend system with this URL I get this error:
"No switch to HTTPS occurred, so it is not secure to send a password"
" Choose "Logon" to continue A dialog box appears in which you can enter your user and password"
Then I can logon to the server and get a lot of XML.
But I have to manually logon to the system.
From the portal I cannot logon to the backend system with the test function. I get the error:
Alias is found, but connection failed.
I guess there must be an automatic logon preconfigured.
How can I do this?
Is SSO necessary?
thanks for any help

Hi Gregor,
thanks for your answer, which was intersting but could not solve the problem. In the meantime I discoverd the reason for it.
You have to insert the connection URL to the BW system at 2 points in the system.
1. You have to configure the XMLA connector with the Visual Administrator.
2. You must implement a system in the portal where you configure all necessary information, also the URL to the BW system.
This seems somewhat strange to me because you will then not be able to connect with two or more BW systems to the portal and VC what is centainly necessary in a real world scenario. Anyway I can now see all Infoproviders of the BW system in the VC, and SSO isn't necessary because you configure the information to login to the BW system directly in the configuration of the XMLA connector in Visual Administrator.

BW system connecting to multiple ECC systems

Hi,
I am new to BW world & has a question to Gurus
1. Can I connecte a single BW system to source from multiple ECC systems (activley) with out any technical issues ? I am assuming that the multiple ECC systems are pretty much mirror images.
2. If possible what are the areas ( at a high level) I need to double check to make this happen ?
Thanks
Hari

Hi Hari,
Yes, you can connect multiple ECC systems to one BI system in one of my project we had more than 20 ECC systems connected to BI Production system.
How this works is because source system and BI system has got different provisions for that,
1) For connecting different systems you simply need to create RFC connection between them. After the RFC is formed you can load data from any of the systems.
How BI system differentiate similar data coming from these systems?
There is a field called 0SOURCE SYSTEM which is used as Compounding field, or primary key field where ever you have data loading from multiple systems, this field basically contains the 3 char source system ID and is used to differentiate records coming from different source system.
How delta is managed in this scenario?
In source system for each data source, a new delta queue is maintained for each target system.

Durgesh.

Can one R/3 system be connected to multiple BW systems?

Hi All,
Is it possible to connect one R/3 source system to multiple BW systems? If yes, is this setup any different from an R/3 to single BW system.
Points will be assigned.
Thanks,
Sirish.

Yes you can connect multiple BW to single R3 source system.
In the delta queue (RSA7 in source system), you have a field with the target system, so you don´t have problem if you have many target bw system, because the data selection is done by system field.
Challenge arises when you have multiple R3 feeding to single BW system and then you have to consolidate the master data say 0material fed from different source system R3 then you can consolidate data using consolidated infoobject.
The following components concatenate to the key of a consolidated InfoObject:
1)source system ID (two-character source system ID; permitted values are stored NW BI table RSSOURSYSTEM)
2)one blank character
3)backend object type (four-character backend object type; permitted values are stored BI table RSBWBEOTYP)
4)master data key value as stored in the source system
Note that the key of a consolidated InfoObject solely consists of non-integrated informations from the different source systems. Integration across source systems results from a (maybee repeatedly applied) data consolidation and cleasing process which unveils duplicate master data keys.
Hope it Helps

Delta and Init Process when R/3 is connected to multiple BW systems

I have a scenarion where one R/3 system connected to 2 BW systems.
In R/3 we plan to have a LO extractor feeding delta to 2 BW systems. I understand delta works fine as delta queue in RSA7 is target system specific.
How are the initializations handled?
What happens if delta in one of the BW system breaks and we need to re-Init?
How would re-init from one BW system affect the delta/init in the other BW?

Hey. I'm assuming both BWs are pointing to the same system/client. I do not have actual experience doing this as I would be very hesitant to have multiple BW systems trying to get delta data from the same source (especially with how logistics behaves).
I know this isn't answering your true question, but could you connect BW system B to pulling the data from BW system A? So something like:
R/3 (logistics) => BW A 1st layer DSO
BW A 1st layer DSO => BW A reporting DSOs/Cubes
BW A 1st layer DSO => BW B reporting DSOs/Cubes
In this way, reporting in BW systems A and B are from the same DSO stage. This would help with any synch/data consistency issues. If A or B reporting providers get corrupted, or whatever, either could be reloaded from BW A 1st layer DSO and everything is still in synch.
Not sure if this helps you or not, but thought I would offer it up as this would probably be my approach.
Thanks
