Clarification regarding loadbalancing in RFC recever adapter

Hi,
what is the loadbalancing in RFC
when do we go with or without Load Balancing option in RFC?
SOAP action in SOAP adapter.
Thanks
dhanush

Dhanush,
If you have more than one instance of server for your Application system you should use Load balancing in that case.
Sometime because of the heavy load on the sever they include more than one server to handle the load...where each request would be randomly assign to the available server. But they comes under one application system.
So when you have multiple instace and if they have creates group to identify them use Load Balancing option.
hope this will help you,
Nilesh

RFC Receiver Adapter and RFC Destination -- Help

Hi,
I would like to configure the RFC Receiver Adapter for the invokation of a RFC on SAP System (Name: ALPHA) using a RFC destination provided by another system named BETA.
I have set External Server as server type.
My first question is: I have to quote an application server gateway and a gateway service. Is this information related to a service on ALPHA or BETA?
My second question is:
It is also necessary to provide a Programm-ID. The destination on BETA is a R/3 connection and doesn't have a programm id. Where do I get this from?
And my last question is:
Is at all possible to use the RFC destination on BETA?
Any help is really appreciated...
Kind regards,
Heiko

Hi Heiko,
I don't fully understand your need but:)
since both of your systems are SAP systems
why are you trying to use external server?
can't you just call RFC on BETA
and inside this RFC on beta call RFC on ALPHA?
in a sync or async way?
can you tell a little more about your requirement ?

michal

Call rfc sender adapter from non-sap systems

Hi,
is ist possible to connect to an rfc sender adapter from non-sap systems? I want to use the the RFC-Connector from http://rfcconnector.com, but in the client connect options there is no way to specify the program id.
Best regards,
Daniel

hi,
you don't need to use RFC type T (with program ID) - you can use whole connection string - just like in the example:
http://www.rfcconnector.com/documentation/examples/client/#functioncall
so just specify: host system number etc.
it should work like that - but let me know as I don't know this RFC connector

RFC Sender Adapter in XI..Possible??

Hi All,
I am trying to send data from XI using RFC Sender Adapter.
Have done all the configuration, ie created a tcp/ip destination in SM59 and then in the RFC adapter mentioned the program name.
In Adapter monitoring i can see the adapter working fine.
When i execute the Function Mouldule i get the following error in SM58.
parameter JCO.Request was <null> (server: RfcServer[CC_RFC_TX1_OUT]1)
Can anyone please lemme know if we can send data from XI box using RFC sender adapter.
Regards,
Sumit

Sumit,
Technically specking this should be possible.. I Havent tried it though..
So, you are using a Sender RFC to send data from XI to XI itself uh?
I have tried configuring a Receievr RFC adapter pointing to XI and it has worked fine.
Also, take a look at these blogs if your config is correct,

RFC Receiver Adapter (Problem)

Hi All,
I have configured RFC Receiver Adapter : Here i have imported a Z FM for example
"" Z_API_DOCUMENT_CREATE_TEST "" having below import paramaters:
LF_DOCNUMBER     TYPE     BAPI_DOC_DRAW-DOCUMENTNUMBER
IV_PF_HTTP_DEST     TYPE     RFCDES-RFCDEST
IV_PF_FTP_DEST     TYPE     RFCDES-RFCDEST
LF_FILENAME     TYPE     BAPI_DOC_DRAW-DOCUMENTNUMBER
1) Now i use MM to fill in two parameters : LF_DOCNUMBER , LF_FILENAME
If my FIle is of kind : test55.pdf     --> LF_DOCNUMBER = test55
                                                       LF_FILENAME       = test55.pdf
For this i have checked in Sender File Adapter "Adapter Specific Message Attributes"
So i write UDF to capture Filename and Filename with extension to fill above shown parameters.
Now i saw target xml after mapping in CC monitor of RWB is as below
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:Z_API_DOCUMENT_CREATE_TEST xmlns:ns0="urn:sap-com:document:sap:rfc:functions">
<IV_PF_FTP_DEST>SAPFTPA</IV_PF_FTP_DEST>
<IV_PF_HTTP_DEST>SAPHTTPA</IV_PF_HTTP_DEST>
<LF_DOCNUMBER>xierror</LF_DOCNUMBER>
<LF_FILENAME>xierror.doc</LF_FILENAME>
</ns0:Z_API_DOCUMENT_CREATE_TEST>
But LF_FILENAME is getting populated to my Z FM at runtime but LF_DOCNUMBER works fine filling up with value.
But when i run the FM using F8 it works , what could be the problem.
Any advice
regards
Srinivas

Hi,
The problem is with the Data types used for LF_DOCNUMBER.
Make this as Char or Numeric in FM and then try. If its of any packed values then conversion will create the problem
Thanks

Dynamic Logon Data in RFC receiver adapter?

Does someone know if and how the logon data (userid) defined in the communication channel for a RFC receiver adapter can be dynamic overwritten? For example using information from the payload?
Scenario: A request for getting HR data is send from a legacy system to XI, mapped to a RFC and routed to R3.
The audit people want to see a real user login into the R3 system to execute the function module and not the technical user defined in the communication channel.

That's exactly what principal propagation is.
You just have to make some (quite a lot, actually) configurations to enable it.
Check these links:

How to send data to RFC Destination(RFC SENDER Adapter)

Hi ,
Scenario: R/3 Backendà RFC Sender Adapterà XIàsome other system.
I have configured the RFC destination (of the type TCP/IP) at R/3 System and have registered the Program ID (specified in the RFC destination) in the XI server and using it in the configuration parameters of the RFC Sender Adapter.
Problem: I do not know how I can send data to the RFC destination. (Should I use a report program/ ABAP Function Module?) Can anybody provide me with a sample code of Report Program/Function module (whichever is required), how to send data to the RFC Destination, so that it may be picked up by my RFC Sender Adapter.
Thanks and Regards,
Siva Maranani

I have one query for you that
I am trying to develop a scenario in SAP XI
SAP R/3 ( RFC function module) sends a synchronous request to the XI and SAP XI will send this request to a third party web application using HTTP receiver adapter.
I am able to send the data/message and it is successfully received at the third party web application.
But I am facing one issue that I am unable to receive any message/data in my RFC module back.i have seen in sxmb_moni that the two messages are displayed in successfuly processed but in SAP R/3 side nothing get happedned
Can you tell me how to use some waiting mechanism in function module to wait for the response from SAP XI.

Problem in receiving messages via RFC Sender Adapter

Hi,
I have problems in receiving messages from SAP backens systems. Sometimes we are getting all messages sometimes not. Strange.
We are transfering report-results via asynchronous RFC calls. To avoid big message sizes we split them up in max. 1000 rows blocks.
Each RFC call on backend side is completed with COMMIT WORK!
We increased the number of connections in the RFC sender adapter. Then it was better, but the problem still exists! Not so often, but sometimes !?!?!
I hope everybody can help me. Thanks a lot!
best regards,
Hannes

hi,
when you don't receive messages what do you see in SM58
on the r3?
any errors over there?

RFC sender adapter not running

Hi there,
I have following scenario: R3 -(rfc)-> XI -(ftp)-> LEGACY.
In R3, i created a RFC DESTINATION (type T) : with Program_ID & GW options (hostname= R3 hostname & service= sapgwXX where XX means sys number). This RFC currently works!!
In the RFC sender adapter, i used the same program ID and the same hostname and service mentioned above.
If i execute SMGW + GoTo->Logged clients, i can see my program ID there but if i click on it, the register status is WAITING!!!!!
Besides, if i execute the program, no information is transmitted to XI via RFC so i cannot see any error message.
Do i have to do anything else??? Maybe i am missing something...
Could you please help?
best regards,
david

Hi,
In sender RFC :
Configuration takes place using a RFC adapter communication channel and TCode SM59 (Create rfc connections).
- All systems that send an RFC via RFC Adapter require an RFC connection to the respective RFC Adapter(inbound). Metadata is gathered in the same way. Register the program id of the RFC adapter in SM59. The rfc destination must be of type "T" tcp/ip.
- You cannot send IDocs using this rfc connection. you must send IDocs to the RFC destination of the IDOC Adapter.
Also check out that Program id is case sensitive.
in the functiion check out for the COMMIT WORK at the end of LUW.

Doubts in RFC sender Adapter

Hi XI Gurus,
Can any body plz explain me about the parameters used in RFC Sender Adapter (like RFC Server Parameters: Program ID, Gateway, etc..)
Thanks in advance.

Hi,
Refer this link there they have given everything clearly
http://help.sap.com/saphelp_nw04/helpdata/en/67/6d0540ba5ee569e10000000a155106/frameset.htm
Application Server (Gateway) : host name of the sender system.
Application Server Service (Gateway): Gateway service of the sender system. This can be the numeric description of the service port in the sender system or the alphanumeric equivalent (for example, sapgwXX, where XX is the system number of the sender system).
Program ID: Program ID of the registered server program. The selected program ID must uniquely describe the RFC sender channel in the configured gateway (Application Server (Gateway) and Application Server Service (Gateway) parameters).
For Program id: In sender R/3 system Tcode SM59
1.Create RFC Destination with connection type: T
2.Choose Registered server program
3.Give program id(you can give any name here, the program id you give in sender RFC adapter and here should be same )
4. Give Gateway host and Gateway value.

Errors in RFC sender Adapter

Hi Guys,
I am configuring a RFC sender Adapter in a newly installed system.
I configured the adapter as per the parematers given in SAP help in the exact way and started getting the error
Error in processing caused by: com.sap.aii.adapter.rfc.afcommunication.RfcAFWException: senderAgreement not found: lookup of binding via CPA-cache failed for AdapterType RFC, AdapterNS http://sap.com/xi/XI/System, direction INBOUND, fromParty '*', fromService 'RD1CLNT020', toParty '', toService '', interface 'Z_TEST', NS 'urn:sap-com:document:sap:rfc:functions' for channel 'RD1CLNT020_IN' (channelId 897afca12ee93b86a5bfcd738c037099)
If I go into SXI_CACHE of the PI system I can see the entry.
My gut feeling is that the adapter is not fetching the metadata properely.
Because I switched the metadata loging from the ECC system to PI system and I got the error
JCO.Server could not find server function 'Z_TEST'
I think in the basis setup we have missed something The version on which we are working is the Latest PI 7.1
If somebody has a document at the the config for JCO or a solution for this problem will be much appreciated.
Thanks & Regards

Hi,
there is no magic with this error - it's a common one
1. my blog - RFC sedenr adapter config -
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
then is still does not work:
2.check out OSS note 730870 - FAQ RFC Adapter
"Question 19:
While sending a RFC call to the RFC Adapter I get a error message like "com.sap.aii.af.rfc.afcommunication.RfcAFWException: lookup of binding via CPA-cache failed..." or "com.sap.aii.af.rfc.afcommunication.RfcAFWException: senderAgreement not found: lookup of binding via CPA-cache failed...". What is missing?"
and you have it working
please let me know if this helped

What function name to use when calling an XI RFC Sender adapter?

Hello experts, I need some help please...
We are trying to setup an RFC Sender adapter in XI 3.0 for the first time. We followed Michal's <a href="/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step on how to setup the RFC destination in the sender system (ECC 5.0 in our case) and the corresponding communication channel in XI. We can make a connection from ECC to XI via the destination, but we are getting an error in the communication channel monitor stating that the JCO.Server could not find the server function '<i>message interface name</i>'. We have tried to use the message interface name, the message type name and the data type name, but all return the same error. What function name should we be using and how does this name get registered with the JCO server?

hi
Have you registered the pragram id properly in sender system ?
Steps to that
1. first create RFC sender adapter in XI and give any name as program id Give Gateway host n gateway service of appilcation system
2. activate it properly
3. program get regiostered on app system
4. go to application system and create RFC destinationn there give the same program id name
now it should work
