RFC synchronous concurrence

Hi
I have a BPM with a synchronous sender step (BAPI call). This BAPI makes a material reservation , checking previosly if the material is locked. If the material is locked I get an error , the BPM checks this error and I try again (3 times).
My doubts:
1- The rfc call (receiver RFC adapter) does synchronous connection??
2- what happend with the concurrence? If I send two messages in one second why the second BPM , rfc call, does not wait to the first one to finish?? I get an error in the first call the material is locked.
    In the SXMB_MONI I see next times
        First BPM start the rfc call at 12:39:38 and finist at 12:39:42 (error material locked)
        Second BPM start the rfc call at 12:39:39 and finish at 12:39:46. This call finish OK.
I thought the second call should wait to the first one finish.
thanks

Hi Gerardo,
The synchronizity on the BAPI call is just that; Synchronous with the current session. I don't think that PI supports cross BPM session synchronizity (happy to be proven wrong).
There are of course many ways to achieve this (not necessary elegant solutions) and I am sure that you can get some experienced forumists to provide you with samples of how they have resolved this.
Bad sample (assuming that ABAP does not support synchronous calls):
- Wrap the BAPI call in a synchronous Java map (assuming that all your calls run through a common classloader).
Hope you can get some better ones coming through.

File to RFC synchronous scenario stopped Picking the files

Hi Experts,
We have a File to RFC synchronous scenario. Till yesterday night it is working fine.
But suddenly it is stooped working.In moni, i can see the failed messages with the Mapping error " Can not create target element, values missing in the queue context "
No Payload in moni / communication channel monitoring / Message monitoring. I've noticed that, wrong files placed in the To-be- processed files and the adapter picked those files and failed in mapping.
I tried by stop and start the communication channel / did some dummy changes in the communication channel and activated. cleared the cache.
But still the communication channel is not working.when i stop and start the communication channel it will try to process the wrong files and failed.
Give me your valuable inputs to resolve this issue.
Regards
Bhargava krishna

Hi Bharghav,
Please go through the below,
Symptom
FTP Adapter is being used in the business scenario for message processing.
During file processing it is noticed, that the FTP sender channel stops
polling. There is no error in the channel monitor or the trace/log files
and the polling jobs are correctly displayed in the AFW scheduler table.
The issue is observed after a network connection issue with the FTP server.
In order to remove the hanging locks from the FTP Adapter, the parameter
'ftp.timeout' setting is required to be set, which releases the lock once
the timeout value is expired. But in the above situation, the value for the
'ftp.timeout' is not taken properly while establishing the data connection
by File Adapter.
Other terms
FTP Adapter, sender, FTP, adapter, timeout, stalled, network, hang, polling
Reason and Prerequisites
Program error
Solution
The hanging situation has now been improved by code changes. Please see
section "SP Patch Level" of this note for a list of updated software
components.
To get this correction available in your Support Package you need to apply
the patch matching to your Support Package version as per the instructions
in the NetWeaver Support Package Stack guide which can be found on the SAP
Service Marketplace as described in SAP Note 952402.
Thanks & Regards

Looks like there is some mapping problems ,may be the RFC connection is not properly configured .Here is the link to configure the connection between ECC and PI :
http://wiki.sdn.sap.com/wiki/display/XI/ConnectionSettingsbetweenECCandPIsystem
May be there is no value retrieved from the ECC system so it is saying null value.
For proper configuration check you can refer the following blog:
/people/community.user/blog/2006/12/12/http-to-rfc--a-starter-kit
I am a beginner so not the full answer is there but may be this would help you.

Http to RFC or SOAP to RFC (synchronous)

Hi,
I need to connect PHP with RFC via XI/PI
Request will be send from php developed web pages to R/3 (RFC) to get data back to web page.
I think to resolve this scenario 1u2019ve two options
1: SOAP to RFC (synchronous)
2: HTTP to RFC (synchronous)
Can you please suggest me the scenario?
Thanks for you time
Regards,
Farrukh Ghani

Hi Ghani,
The two options you mentioned we can use,but it depends on how PHP web site going to send data,if it is going to send webserive then use SOAP adapter,you are expecting response ,the RFC wil work as synchronous.
If it is not Web Service other option is HTTP,receiver would be RFC only.
How to configure SOAP->XI>RFC or HTTP->XI-->RFC scenarios,simple search in sdn will give many blogs,search in sdn,
if you unable to find right one let me know..

Response structure empty for HTTP to RFC synchronous scenario

Hi experts,
I have a HTTP to RFC synchronous scenario.
The request is given to Price List ZBAPI.
The input to the BAPI is date, material no, customer no and condition type.
The output I am fetcching from access sequence table into the table FINAL type structure ZFINAL which is
then sent back to source as a response.
But the problem is that I get this table as empty although BAPI returns data
Regards,
Mozila

Dear Mozila,
How did you check that BAPI returns data? Did you use an exact message sent from PI to the receiver business system? If not, I would suggest to take the message which was sent by PI to the receiver business system and use it when performing BAPI test.
Are table contents received by RFC adapter on PI side (can you see BAPI execution results in message contents for response message received by RFC adapter)?
Can you see any errors in RFC communication channel?
Did you check message monitor in Integration Server for the particular message? Are there any errors?
Please also check your message mapping - this may also cause the error in case RFC adapter receives correct results, but HTT client receives empty table.
My regards,
Vadim

Java Proxy - XI - RFC Synchronous Scenario OUTBINDING Problem.

Java Proxy -> XI -> RFC Synchronous Scenario. Problem
Hi,
 I'm doing a Java Proxy -> XI -> RFC Syncronous Scenario.
 A Java Server Socket is running as a Demon. When a client make a request to the Java Server Socket, this one call Java Proxy Client and set up the parameters.
 The first time that execute the scenario it works perfectly but no the next one and so on.
 The error when I check the monitor (TCODE: SXMB_MONI) is in PLSRV_OUTBOUND_BINDING.
<Trace level="1" type="B" name="CL_XMS_PLSRV_OUTBINDING-ENTER_PLSRV">
<Trace level="1" type="T">no outbound binding found.</Trace>
<Trace level="1" type="T">No standard agreement found for , DES210_DEV, , JPX_DEV, urn:servipago:SERVIPAGO_SAP_02, mi_os_t1</Trace>
</Trace>
<Trace level="1" type="B" name="CL_XMS_MAIN-WRITE_MESSAGE_TO_PERSIST" />
And it has sense, because my scenario doesn't begin with the execution of FM (RFC).
A Hint, my services in the first try are:
 Sender Service: JPX_DEV (Java Proxy Client)
 Receiver Service: DES210_DEV (R/3 4.6C)
But the second try and so on the services that I saw in the monitor are:
 Sender Service: DES210_DEV (R/3 4.6C)
 Receiver Service: JPX_DEV (Java Proxy Client)
I can't understand why they swich each other.
Any idea?

Hi,
Outbound binding problem is because of Reciever Determination/Agreement is not activated or refreshed correctly.
Try to recreate or refresh and activate it. Then check it.
also do the cache refresh in SXI_CACHE.
Also in go to Integration Builder(XI home page)->Administration->Cache Overview and do all the cache refresh.
Hope this helps

Moorthy

Http-xi-RFC synchronous call - multiple records ?

Hi Gurus,
Can we have multiple records processing in RFC synchronous call ? for ex, BAPI_COMPANY_GET_DETAIL. I want to feed multiple company ids and get the responses in browser.
I have changed cardinality in message mapping and interface mapping as o to unbounded. Tested the same which works fine.
But, when I activated the interface mapping, I get an error which says I can not use multi mapping in synchronous RFC call.
what is the alternative ? please help.

HI,
It is better to use the RFC lookup in mapping and get the multiple records , i men each one for one lookup , so that in your mapping use UDF for RFC lookup.

Hi Jain,
For JDBC (Sender/Receiver )Scenario we have to Install the JDBC Drivers on XI Server.
Use those Driver name and Connection in JDBC Adapter to connect to the Database.
For RFC Sender Adapter we have to create the Program ID in SAP R/3 side.
For RFC Receiver no need of any Extra settings.

How to test the RFC to Flat File scenario
Type 3 ABAP Connection :
ex 1) If we want to execute any function module from one SAP system in another , we need type 3.
We define an RFC destination say ECC6CLNT100 with required parameters.
and to test it go to SE37, select any common sap function module and when you execute that it will ask
for RFC destination. you provide this destination and the function module will be executed in the target
system.
ex2) when you create a partner profile, you need to create a port and for creating a port, we need to
specify an RFC destination. here also we use type 3.
Type H.
ex1) when we need to send xml messages from an SAP system to any other system, we need this.
For example when we send messages using proxy from SAP system to the integration engine of XI, we
need type H.
Type T.
ex1) To we make an RFC call from R/3 to XI , we use sender RFC adapter in XI.
In R/3 system we need to create an RFC destination of type T.
Different types of RFC are :-
Asynchronous RFC - aRFC
Synchronous RFC - sRFC
Transactional RFC - tRFC
Queue RFC - qRFC
Parallel RFC - pRFC

FILE To RFC Synchronous

Hi Experts,
I have a requirement of FILE TO RFC (BAPI_ABC) synchronous .Everything is ok with it.
But Once I have called BAPI_ABC, I need to call BAPI_TRANSACTION_COMMIT and pass it the hardcoded string u201CXu201D to save the changes made in SAP.
For this in Target Side of mapping i have called this bapi after BAPI_ABC. this wont work.
because with synchronous intefaces we can't do multimapping(1..2)
now when will I call this comit bapi,?
and What will be the probable solution for it.
Shall I use BPM or Proxy. but my client requirement is "everything should be done in PI side only"
Kindly reply it with your best.
Regards,
Sumit

Hello,
I had similar problem and i could resolve this issue with help of SAP Note 1342143 - RFC Adapter: WAIT during call to BAPI_TRANSACTION_COMMIT.
So all you need it is to set up next:
In receiver RFC adapter
Check "Advanced Mode"
Check "Commit Handling for Single BAPI Calls"
Add the following Name-Value pair to the table:
Name: BAPICommitWait
Value: true

SOAP to RFC synchronous scenario with File without BPM

Hi Folks,
I have a requirement that has to be done with out BPM!!!
Requirement:
Soap will trigger the request to SAP(RFC) and SAP sends the response to a file and then after SOAP has to recieve the ACK from PI.
1) Can we do this by without using BPM
2)Can we use without BPM module entries for SOAP Sender
Please suggest and help me out in this
Thanks in advance,

vivek

Hi Vivek,
Why not have the SOAP interface defined as synchronous?
You can avoid using BPM that way.

File to RFC synchronous scenario

Hello Friends,
I have a file to RFC scenario.

Payload not visible in cc monitoring for SOAP-RFC synchronous AAE scenario

Hello consultants,
I have a synchronous SOAP-RFC scenario over the AAE (Java only). When I test the service in WSNAVIGATOR the response message contains an error that results in the error message:
"<s:SystemError xmlns:s="http://sap.com/xi/WebService/xi2.0">
 <context>XIAdapter</context>
 <code>ADAPTER.JAVA_EXCEPTION</code>
 <text><![CDATA[
java.io.IOException: Parsing Error: org.xml.sax.SAXParseException: The processing instruction target matching "[xX][mM][lL]" is not allowed." the same errror is present in communication channel monitoring for the SOAP adapter.
The status in message monitoring however is succesful.
Is it possible to check the payload for the response message of the RFC call. In CC monitoring I cannot access the payload, it is not there. It does not have to be in cc monitoring, anywhere would be fine.
Since this is an AAE scenario there are no messages in SXMB_MONI.
All tips are appreciated.

JDBC to RFC synchronous scenario (Urgent).

Dear forum,
My requirement is data is populated in oracle data base.we are fecthing the data from database through XI and sending it to R/3. RFC is sending the response (suceess/failure) to XI. And XI is updating the status message into database.
For this,I have done the JDBC - RFC - JDBC syncronous scenario using BPM. .I got the successfull message under message monitering.Problem is I cannot able to find the data for RFC and JDBC reciever.
Please find the following Configuration steps for the above scenario
3 data types
JDBC request, JDBC response one dummy structure to capture RFC response messages.
3 message types for the above data types
5 message interfaces.
OB request,
OB ABS request,
IB Asyn for dummy,
Syn ABS (JDBC req and dummy structure),
IB JDBC response.
4 message mappings.
Mapping between JDBC request to JDBC request dummy.
Mapping between JDBC request dummy to RFC request.
Mapping between RFC response to JDBC response dummy.
Mapping between JDBC response dummy to JDBC response.
3 Interface Mappings.
JDBC request to JDBC request dummy.
JDBC request dummy to RFC request and RFC response to JDBC dummy response(Synchronous request and responce) .
JDBC dummy response to JDBC response.
Integration Process.
Used following steps.
Recieve step asynchronous -> Send synchronous -> Send asynchronous
I can able to see the payload for sender under communication channel.But the data is not reached to RFC.can any one help me to come out of this problem.
Points will be awarded for helpfull answers.
Thanks & Regards,
Naresh.K

Hi Seshagiri,
We are trying the same scenario with out using BPM.
Following steps has been done in design(IR).
2 data types for JDBC request & JDBC response.
2 message types for the above data types.
1 outbound synchronous message Interface.
2 message mappings (JDBC request -> RFC request) and (RFC response -> JDBC response)
1 Interface Mapping.
Could you please let me know how to maintain the collaborative profiles & and agreement details in Configuration(ID).
Your valuable assistence is required to complete the interface.
Thanks in advance.
Kind Regards,
