RFC connection between two SAP systems (with SAP router)

Hi!
I would like to set up a RFC-connection from SAP Solution Manager to other SAP system.
The network connection between the servers is VPN.
How can I set up this RFC-connection, if my connection between two SAP systems looks as follows,
(I use the following SAP routers)?
my server --> customer
my server --> internal SAP Router server xy (10.101....) --> SAP Router customer 2 (10.1....) --> SAP System customer (134....)
Back-way
SAP Systeme customer --> SAP Router customer (134.1....) --> internal SAP router (212.6....) --> my server
How can I set up this RFC-connection, if my connection between two SAP systems looks as follows,
(I use the following SAP routers)?
something like:
/H/10.101..../S/sapdp99/H/10.1.4..../S/sapdp99/H/134...
Thank you very much!

One R/3 system connecting to TWO BW systems

Hi ,
When we connect two bw systems to one R/3 system,
could you please exlain what is the imact to SAP and BW in terms of query performance, batch performance,Develoment ,Quality system,security,BW Support.
Thanks in advance.

kranthi

Hi,
Well at first thought, i wouldnt go for the Landscape that you are suggesting. Because of obvious reasons:
1. Performance issues while loading, on reporting.
2. Data sources might work fine for one system and not for the other, then the whole setup is hit badly.
3. Security and management of the 2 systems, will be a big task.
4. Jobs would take a longer time if the Batch processes are not sufficient.

ME 5.2 connection with two ECC systems

Hi Sergiy/Experts,
Need to connect ME 5.2 system with two ECC & SCM systems for a scenario. Is it possible to connect?
During SAPMEINT standard interface we get connection credentials point for only one ECC system.
How I can meet the scenario for ECC system?
will appreciate your help.
Thanks in advance

Hi,
Yes, it is possible. See my answer here:
http://scn.sap.com/message/14408145#14408145
There is a design limitation: plants must be unique across the different ERPs connected to the same SAPMEINT.

Connect Same BO server to Two BI system QBW and DBW

Hello friends we are using same BO server to connect to two BI system DBMW and QBMW.
we are not able to see the OLAP Cubes during the creation of universe connection using the Quality system QBMW and Application server "sapbmw01" client 100, system # 00. But we are able to set up the connection in our development system DBMW.
We have also done OLEDB release setting for queries but my universes are based on BI Infocubes and not queries
I will highly appreciate if you can let me know if we need some special role to access the OLAP Cubes during the creation of universe connection using the Q system. I have also imported the authentication OF SAP ALL role to BO.
Surprisingly we are using SAP_BW_ALL in Quality system still we are not able to access the infocubes but we can see the queries in Quality QBMW . is there some thing missing in CMS IN BO to make that work.
Thanks
Soniya

Hello Meryll. We have referred to SAP documentation on BO which say Universe can be build on top of BI infocubes and which works correctly in our development system. so that proof that we can build webi reports via olap universe directly on top of infocubes. But now the problem is when we want to set up the same connection on BO server using the Quality box which is closed system we do not see the infocubes.
so I will highly appreciate if you can let me know what is missing in Quality box than the Development box, since I checked roles its sap_all in Q box also and I checked Cubes are the same as D box.
so why it is not working in quality box , is that some thing with the Licence key do we need seperate license key for each box LIKE D, Q, P
Please help me this is holding our Go Live at BMW.
Thanks
Kind Regards
Soniya

Can some one help me.
Thinks.
Issam

Hi,
Through RFC (SM59) u can connect the TWO SAP systems.........
If u are in SAP 4.7 , once u enter into SM59 u will be finding the R/3 Connections... U have to choose that...
if u are in SAP ECC , then u will be finding the ABAP connections.. U need to choose that and create the RFC connection.....
But U need to know the details :
1. Target Host Name .
2. System Number.
3. Logon details...

One server connected to two SLD.

Hi all,
I have an scenario were a system must to be connected to two XI system ( each one with their own SLD ), using ABAP proxy. Is this possible to do?
Thanks in advance,
Sidney

Hi,
Thats not a good way to go through.. but since it is your requirement..
Create Techinical and Business systems in both the SLDs with same names. DO NOT assign the Transportation Target for the source BS in the source SLD. Also, do not put any value for the Transportation Source for the Target business system in the target SLD.
Both the XI systems must have the required HTTP ports created with the corresponding R3 systems to enable the proxy communication.

Two SRM systems connected to One back end system

Hi..
Note: I have posted this message earlier ......but couldn't find that. I am just reposting the message:
In our quality environment, we have two SRM and two backend systems. One for testing purpose and other for training purpose. We are planning to remove one back end system and connect both the SRM systems to one backend system.
1. Is it possible to have this landscape?
2. In SRM & R/3 we can define two RFC connnections but from R/3 side, I am not sure how the system will determine the respective RFC connection during GR or any other process.
3. Are there any other difficulties?
We are in SRM 4.0 using Extended classic scenario. We are using SRM for processing shopping cart, Po and confirmations.
Please advise.
Thanks.

Hi Prashanth,
is very much possible.
for this you need to configure the partner profiles.
need to define port
need to configure inbound paramters and outbound parameters.
we20 - create partner profiles.
define outbound parameters and inbound parameters of the message type.
we21 - define port.
under Transactional RFC.
and create a distribution model and add message type.
revert back to me if any problem still you find.

Connecting two BW systems to the one R/3 source system

Hi all!
I have to connect two BW Systems to one R3 system. In our last tests we have had problems trying to connect two BW servers simultaneously with R/3 source system because it allows only a logical system name for each R/3 client, and (We guess that we need to define tow diferent logical system name, one for each connection). This has been generating errors when we try to load data from R/3 to BW because, we guess, R/3 does not recognize the BW source system in the ALE connection for someone BW systems at transfer data. In this moment I have one connection active (BW1-R3). The BW2-R3 connection is already inactive. Does anybody know how perform this? we need solve the transfers problem as soon as possible.
Thanks! Judi

Ah...
please don't post twice the same question...in these forums we are always the same !!!
You can close this thread to avoid to look in two different posts...

When we connect two bw systems to one R/3 system?

Hi ,

Regards,

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

Connect two BW systems to one source system

Hi Experts!
I would like to know if I can set up two BW systems connect to one source system. We copied and built new BW system (BW2) from existing BW system (BW1). We need to have both system connect to one source system. When I execut Restore from BW2 - RSA1 - Source System, I'm getting a following prompt:
"Connection cannot be used. The connection BB is used in the DEV400 source system as a connection BW1400 to BW. Do you want to delete this connection in source system".
If I select "Delete" then it replace exising connection between BW1 - DEV and creates new connection BW2 - DEV. If I go back to BW1 and do restore then same thing happens as BW2 connection removed.
Is there anyway we can set up two BW systems connection to one source system with restore? Connection works fine since each one can connection with no issues. Just when I do restore, it removes other connection.
Thanks.

Two portals connected to one BW system

Hello

We have done the same thing for ESS we had to portals connected to one r/3 but beaware when we change the config for one on the backend r/3 side the settings for the other is also affected.
there is no issue with the load in this scenario and applications work fine independently as well.
but before doing this just ask your self it is really required cant i create 2 differnt roles and manage the display of the same using the themes?
but still if u wan tot do the same it is possible

Of course you can.
Just have to have the RFC destinations in place and use the
CALL FUNCTION '....' DESTINATION '....'
commands in ABAP, check out the ABAP forums for more info.

Use snoop.
snoop -d <nic> - will give requests and replies coming/going in/out of the specified NIC.
snoop -d <nic> <MAC address of the target host> - will give requests coming from the required host.
