Error in RFC communication

I am trying to make a communication RFC ( ECC - > XI ), but when I verify in transaction SXMB_MONI of the XI the message does not arrive.
If I verify the SM58 of the ECC I see the following error message.
"Commit fault: com.sap.aii.af.rfc.afcommunication.RfcAFWException: Channel"
If I test the connection for the SM59, everything is OK.
Somebody would know what it is happening?
Thanks!!

Hi,
Can you look into the Sender RFC adapter and provide us with the exact error message from Comm Channel Monitoring?
Also, make sure that the same program Id is used in the TCP IP Connection and the sender rfc adapter and try to make some dummy change and activate your adapter again,

Hi All,
I'm having the same problem myself... There is another simmilar thread at:
[/message/448277#448277 [original link is broken];
It seems that thread has progressed further that this one.
Both seem to be errors connecting LSO to Collaboration rooms. I'm getting both error messages when I try to do the same API connection functions from different points in the system, so I'm guessing that they are the same error. IT seems to be an SSO issue.

Hi Prabash,
could be a handful of reasons.
Please open a support message to SAP and grant remote access to your system. Apart from that, please consult the documentation on RFC connection to TREX:

Error in RFC communication with XI

Hi,
We are trying to establish SAP -> XI communication. I think we have done all the required configurations in SAP, XI SDL and XI Directory. When we execute RFC in Se37, We get a short dump. The error details in ST22 (Dump Analysis) are:
Runtime Error: CALL_FUNCTION_REMOTE_ERROR
Error: "call to to messaging system failed: com.sap.aii.af.ra.ms.api.DeliveryException: Received HTTP response code 500"
This is very urgent. Any prompt help will be really appreciated.
best regards,
Sanjeev Kumar

Hi,
I suppose you are using a RFC sender adapter to communicate with XI. This is the error that you get when u configure your RFC sender adapter wrong. Check teh followign weblog and make sure you have specified teh parameters correctly.

RFC communication error

hi guys,
our company has SAP servers in location A which often communicates with servers in location B. recently we moved both DEV and PRD servers to location C from A. the servers from B and C communicates via a VPN link.sequel to this movement we changed the IP configuration of all the systems. presently users in location B can access the PRD server in C but are not able to access the DEV server.
the following error messages appears:
ON PRD
TMS Alert viewer
transport control program tp ended with error code 0212
error:could not access file as supposed
command:SHOWBUFFER PRD PF=
SAPDEV\sapmnt\trans\bin\TP_DOM
while on DEV
message:RFC-communication failure
RFC communication error with system/destination
partner not reached
would appreciate if u culd profer a solution as soon as possible
Regards walata

Hi Walat,
User access problem :-
You located at location B are not able to access server DEV which is located C
Pls take help from your system administrator for doing below task if you are not aware about output
From location B try to telnet server DEV on port 32<NN> or 36<NN> ( <NN> is your instance no of DEV )
for e.g
from command prompt run the following command
telnet < dev server ip > 32<NN>
check the ouput
How to check the ouput
1 after giving the above command, if you get blank screen it mean ports are open
2 after giving the above command, if you get ouput on screen like " conneting to server < dev server ip > it mean ports are not open
If the ports are not open then inform you network team that port mention aboev should be open for users.
once the ports get open check above step again , if you get the blank screen , then you wil be able to login to SAP
Server to Server Access problem :-
From server DEV to PRD and vice versa check whether you can share the drives .
if yous system team that yor PRD system should be able to to access the share folder sapmnt of server DEV ( SAPDEV )
As well as check server to server port 33<NN> is open or not
Any query pls reply.
Thanks

ERROR in the RFC communication when parabatch is set to more 3 (default)

Hi experts,
We have a 10 blades BIA system connecting to our BW Production. When we set the parabatch to more than the default 3 (we set to 4 or 5), We keep getting 'Batchpara Error' and 'Error in the RFC Communication: Error when opening an RFC Connection' during the initial index build. Here are what we do and what we see:
1. set parabatch to 5 and build 1 initial index (cube is 46 mil rows, 22 GB in size) - Failed with the above errors
2. set parabatch back to 3 and build 1 initial index (same cube as above)- successful but slow
3. set parbatch back to 3 and build 2 initial indexes simultaneously (16 mil rows/4GB and 6 mil rows/2 GB) - Failed with the above errors.
In the BIA index log I see the following error:
Error in the RFC communication: Error when opening an RFC connection (TREX_BIP)
Message no. STREX005
In SM37 in one of the logs I see the followings:
Parabatch Error
Any light you can shed on why we are encountering this issue will be much appreciated. Also, I observed that there is a long idle time in all systems (BIA, DB2, BW) and seemed like their respective resources were not utilized at all. Once in a while I do see surge of cpu/memory usage in all systems but not too terrible. I'm puzzled by why there is such long interval of idle time in all systems while the initial index build is going on.
BTW...we did the same thing (set parabatch to 5, and run parallel initial builds) in our non-prod BIA (2 blades) and QA BW landscape and do not have any issue at all.
Thanks!
Kee

Hello
PLease check the sapnotes and check the developer trace for more information.
Note 314530 - Number of RFC/CPIC connections for external clients
Note: 1070034
It can also be because your system has reached it its max gateway connections...also check whether you are getting error message "Communication error, CPIC return code 017, SAP return code 450
" in sm21 ???

RFC Communication error when doing initial indexing

Hello Everyone,
I have a quick question, when doing the initial index rollup for a BIA index the job is failing with RFC communication error.
We currently have the setting related to " TREXRfcServer threads" set to "Automatic Changes" in order to avoid the RFC Communication errors when loading big loads in BI system.
We currently are on Revision 49.
I also have referred to OSS Note 1138603.
The issue is when I am rolling up the BIA Index the rollup job is failing with RFC Communication errors.
The Global parameters within BIA are:
BATCHPARA - 2
NUMPROC - 5
PKGSIZE - 10000000
SUBPKGSIZE - 20000
We have two app servers with 52 Dialog processes and 25 Background processes.
Any help would be really appreciated.
Thanks
Dharma.

Removing references to systems and ports
Issue:
When the initial indexing is being carried out for an InfoCube to
create the BIA Index and there is more than one application server in
the system the job is failing with the http error.
Hello Everyone,
Thanks for the input, after the automatic changes was configured for concurrent requests the error is different right now.
The error message is,
"Remote communication failure with partner http://<Removed>:<removed>/indexCellTable"
Overview/Background:
When the indexing job is triggered as a background job the failure happens when the S table index is being filled.
In our system where we are trying to do the stress testing we currently have two app servers and one central instance.
When I limit the RFCGROUP in RSDDTREXADMIN table to one App server in terms of logon group the job finishes fine.
Whereas, when I do not limit the RFCGROUP and all app servers are open for access the background job finishes with the error message
Remote communication failure with partner http://<Removed>:<removed>/indexCellTable.
We have looked into the OSS Note 1102652 and our BASIS team confirmed that they were able to ping from BI App servers into BIA blades and vice versa.
We also confirmed if the local gateway was used for connectivity.
The above issue was not in other systems where we only had one server.
We currently are at Revision 49 and SP 13 in BI.
We have E5345 Clowertown blades (2 x 4) 16GB blades.
Please let us know if you need additional information.
Thanks in advance for the input.
Dharma.

BPC 7.5 NW- error 'Name or password of RFC Communication user is invalid '

Hi
Environmen: Win 2008 R2, CPMBPC 7.5 SP09, BW 7.2 Sp09, .NET BPC 7.5 SP09
I just completed installing .NET BPC 7.5 and when I try to open BPC Server manager, i get "cannot coonect to ABAP server' error.
When I try to open the website http://localhost/osoft I get the error "name or password of RFC communication user is invalid".
I see the same error in the BPC logs as well.
I have the tried the following so far:
1. Created single domain user for the three communication users BPC_sysadmin, BPC_admin & BPC_user.
2. I momentarily changed to dialog users and logged in to check their fucntioning.
3. I have generated their relevant profiles. Inlcuded SAP_ALL, SAP_NEW for the sysadmin ID
4. I have disabled firewall, allowed port 80 on Windows firewall.
5. I have disabled UAT
6. I have followed the rest of the installation as per inst guide.
When I run BPC server manager diagnostics, I see error "SAP ABAP server connection:database connection:status error".
Can someone tell is there anything else that I could try ?
many thanks
Sreekanth

Hi,
If when you launch BPC Server Manager, you do not get "Cannot connect to ABAP server", this means user BPC_SYSADMIN is connecting correctly. And assuming you had invalid RFC user in BPC Web, your issue is then only with user BPC_USER (or BPC_ADMIN if the issue is with BPC Admin client only)
If you do get that error, it means the error is for more than one user, so I would look for something big missing.
In point 1 you mention domain users, make sure in BPC Server Manager under "reset login credentials" that you do not have windows users specified there as it's a common mistake, those should be your 3 BW communication users
On BPC .Net server, if you installed SAP GUI, run an MDX_PARSER test in SM59 to check librfc32.dll is working correctly
Also quite common issue it is possible your background users have wrong authorizations; in PFCG check the roles SAP_BPC_SYSADMIN SAP_BPC_ADMIN and SAP_BPC_USER were copied to customer namespace and that the role are active (user tab should be displaying green light) and assigned to the background communication users
Also check the background users are not locked in SU01 (if they are locked the password saved on .Net server was or is not matching the real password defined on NW server)
Thanks,
Julien

"COMMUNICATION FAILURE" during JCo call. Error opening RFC connection

Hi
I am trying the following scenario
/people/varadharajan.krishnasamy/blog/2007/05/11/how-to-use-digital-certificates-for-signing-encrypting-messages-in-xi
In SM 59 test connection of AI_RUNTIME_JCOSERVER throws error " Error opening RFC connection"
Do I need to activate any service in SICF and do I need to do any IE configuration (sxmb_adm)
pls let me know the steps to solve this
thanks
manian

Hi Manian,
pls chk with ABAP system tha tu have given the correct PWD and CLNT No
Use
You need to create the following RFC destinations with both transaction SM59 (ABAP) and the Visual Administrator (Java):
●     AI_RUNTIME_JCOSERVER
Points from the Integration Server to the mapping runtime. The program ID corresponds to the entry under JCo RFC provider for the J2EE Engine (used for the mapping runtime, value mapping, and the exchange profile).
●     AI_DIRECTORY_JCOSERVER
Points from the Integration Server to the Integration Builder. The program ID corresponds to the entry under JCo RFC provider for the J2EE Engine (used to refresh the runtime cache).
●     LCRSAPRFC
The RFC destination LCRSAPRFC is required for the connection to the System Landscape Directory (SLD). It is used to read the exchange profile.
●     SAPSLDAPI
The RFC destination SAPSLDAPI is required for the connection to the SLD. It is used by the ABAP API.
Depending on your client settings, it may be necessary to log on to your Integration Server host as SAP system user with the authorization to maintain customizing tables and to release transport orders.
User SAP* or DDIC does not have these authorizations
Thanx

Error in RFC & to Solution Manager System

Hi,
Error in RFC & to Solution Manager System
can anyone tells me why this error occurs???
With regards
kulwinder

FYI
We have just had same issue thaat in certain scenarios with RFC communication BACK to Solution Manager from Satellite system we got the error. We resolved this by looking at the RFC user used in the BACK connection (i.e. SOLMAN<SID>) on the Solution Manager and changing the user type from communications.
Hope this helps someone else, I spent ages digging around for an answer to such a simple fix

Hi,
This solved this issue for me:
Setting Maximum Database Connections
Perform this step only if you want to check or change the values.
       1.      Open the Visual Administrator tool.
○       j2ee admingo.bat if you also use SAP WAS ABAP.
       2.      Log on as an administrator.
       3.      Choose Server ® Services ® JDBC Connector.
       4.      Choose the Properties tab strip and select sysDS.maximumConnections.

RFC 2 File Error in RFC sender: java.lang.ArrayIndexOutOfBoundsException

Hello,
I'm sending data asynchronously from R3 to a file through XI, I've got the RFC destination (in R3) and sender RFC channel (in XI) configured and tested. Working fine.
Then in my report I've got the following code that sends 1 string and 4 internal tables 2 to XI:
CALL FUNCTION 'Z_RFC_ENVIAR_DATOS_PSP'
    IN BACKGROUND TASK DESTINATION 'SAP_2_XI'
    EXPORTING
      RUTA                       = p_ruta
    TABLES
      IT_DEMANDA           = p_gt_demanda
      IT_STOCKS              = lt_stocks
      IT_CUARENTENAS   = lt_cuarent
      IT_COMPRAS           = lt_repartos.
COMMIT WORK.
I've done that king of connection several times and allways worked but now I've got that error in the communication channel monitoring at RWB:
Error in processing caused by: java.lang.ArrayIndexOutOfBoundsException
And no message is created in XI. What can it be?
Thanks for your help

Hi Chen Lin,
The problem is with the adapter but no message is generated yet in XI, so I don't have XML yet.
The RFC sends the data to XI through the RFC destination and at this point something is wrong because that error is produced. The error is visible in both sides, In transaction SM58 at R3 I can see the error that tRFC hasn't been precessed because the ArrayIndexOutOfBoundsException.
But if I go to communication channel monitoring I can see the same error too, so that confirms that the communication between R3 and XI works fine but something is wrong and the error don't give me more details

Error in proxy communication with BI (special characters in fieldnames)

Hi experts,
We are on our way to create some interfaces between PI 7.1 and BI 7.0.
These interfaces will communicate each system by means of ABAP proxies.
In BI side, in order to operate with the most up-to-date information,
we are using APD (Analysis Process Designer). It consists of a query
execution that at last inserts data into a DSO. This DSO is a table the
system creates, its fields are named with the prefix /bic/ and that is
the problem. BI team tried not to use it but with no success, this
prefix seems to be mandatory when working this way. Currently, RFC
communication is used, that is Outbound RFCs come along with DSO tables
and thus, data acquisition and assigning is done inmediately. Problem
is that we want to move to proxies without losing this benefit. That is
the clue.
So, back again in PI, once we try to create all the necessary stuff for
ABAP proxies, the system prevents us from creating the Data Type for
fieldnames starting with '/' so we cannot create the Service Interface
and so the proxy.
Error message looks like:
Value "/" is not allowed for the attribute "name" of type "NCName" in
element
Besides, we have tried to use the RFC metadata as a service interface
but it didnt work out, because '/' characters in BI were represented
by '-_' once we imported this metadata.
Basically, this is the problem we are facing right now. We know that
ABAP proxy is one of the best practises in terms of communication
between WAS servers and due to this, we think we might be missing
something in between.
Is there a way to work with ABAP proxies and this BI internal
fieldnames without having to reassign fields before calling the Proxy
methods and classes in BI?
Could you please help us on this issue?
Thanks a lot in advance and best regards,
David

Error in remote-communication

Hello BIA experts,
last Saturday my process chain aborted. The reason in the application log (SLG1) was:
Error in remote-communication with partner http://<blade>:30003/IndexCellTable.
At first I thought the rfc connection or the index service was not available, but in both logs are no entries for this time.
The system runs with Rev48 and this is the first time this error occured.
Any ideas?
Best Regards,
Jens

Hello Vitaliy,
I mean there are entries in the log files, but not for this date and time. I looked into the traces TrexIndexServerAlert, TrexNameServer_History, TrexRfcServerAlert, TrexRfcServer and TrexTCPClientAlert. I couldn´t find any information.
Since 3 weeks we run with Rev48 and I never get an error like this.
I will have a look at this, if it occurs again I´ll create an OSS.
This is not the first time this cube is indexed.
This is something I found also in the application log:
Creation of the BIA index for InfoCube 'FACPRJPRD' terminated while filling (RSD_TREX (Messages from TREX Aggregate Area))
Thanks for your answers
Best Regards,
Jens

Schedule Receiver RFC communication channel to call R3 RFC-FM.

Hi,
I have requirement that I need to schedule/trigger from PI to RFC call R3 function module. Wonder if anyone here has done similar thing before? I tried to use ATP (Availability time planning) in RWB. But this seem does not success for me as there is no response and error message for this.
Below is my configuration detail:
Configured:
1. Receiver communication channel - RFC
2. Receiver agreement with the RFC message type assigned.
3. Scheduled receiver RFC communication channel via ATP daily
*(It is possible to make scheduling job in R/3 but we are not considering this way)
Please let me know if anyone has done this before or any other suggestion to do the scheduling from PI.
Thanks!
Regards,
SP

Hi SP,
As you mentioned, ATP would allow adapter to be open and in start state. Adapter's RFC, SOAP, JMS would need some other application to trigger the message processing because these are not like pooling adapter's File, JDBC and Mail. RFC adapter channel always listening to the RFC port and FM execution. Once FM from R/3 executed then the RFC adapter would trigger it's message processing.
For Sender RFC channel: In order to trigger the RFC adapter execution at particular time then you should write a simple ABAP code which would act a batch application and which does the triggering the FM and Sender RFC channel.
For Receiver Channel: For Receiver RFC channel it's bit trichy because here you have force Receiver RFC adapter to connect backend the execute or initialize the variables without having any XI message triggered from Sender PI channel.
I have 2 ideas:
1. A little difficult approach, similar to the ABAPbatch code, you need to write a java adapter module which can trigger RFC receiver channel to connect and do an initialisation at FM at regular interval.
2. Simple approch configure a File-> 2-> RFC receiver scenario, configure File sender adapter to pick a dummy file at regular interval and RFC receiver channel does the rest.
Please let me know still you have any doubts,
Thanks,
RK
