RFC Call from PI freeze ECC system

Hello experts,
we actually load master data in our ECC environment that are sent to the PI environment via IDOC, the integration of those IDOCs in the PI system make RFC call in ECC and after a few minutes, the ECC system freezes.
All dialog process are occupied with report SAPLARFC/SAPLERFC/SAPMSSY1 with user PI2ABAP and WF-BATCH.
We have increase the number of dialog processes, reduce the parameter rdisp/rfc_max_own_used_wp to 50, but each time all the dialog processes are taken until the system freezes.
DO you know which parameter can restrict the number of dialog process used for RFC call?
or maybe a method to avoid this high consumption of all dialog processes in the ECC environment?
Many Thanks.
Thibaud.

Hello Juan,
we have set this parameter to 3, but it seems to have no effect, I have applied the note 3223 that affects
- rdisp/wp_ca_blk_no (for wp_ca blocks)
- rdisp/appc_ca_blk_no (for appc_ca blocks)
but now we have a problem at the start of the instance that does not support the new value and lead to the error
Shared Pool Space exhausted.
How can i check this value and can I modify it?
Thanks.
Thibaud.

The webdynpro/ABAP (WDA) calling RFC enabled FM of other ECC systems

The webdynpro/ABAP (WDA) has problem calling RFC enabled FM of other ECC systems.
WDA expects all the ABAPs, RFC FMs of remote system(DEV, QA..) to reside inside its own instance.
It is hard to transport and maintain these ABAPs FMs into a portal ABAP WDA instance.
Proxy generation at WDA client:
=======================
1. If we can make an XI enable an ABAP or RFC enabled FM of the remote ECC,
I think the XI proxy classes can be generated at the client WDA system.
Other options?
How do I do it? Can you give some tips.
2. How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am stuck with the above as the webservice option is not available at our ECC server. It does not have a java engine installed for webservice to be available.
Can you help on the above 2 options?

Hi Mike ,
 Answer of 2.
How do I manually code the RFC Call to BAPI/FM from Webdynpro controller or other interface?
I am doing same thing for my current SRM implementation.I am taking data to SRM server from another R/3 server .
This is solution I have used
1) First of all I have made ABAP connection in SM59 .
Go to SM59 .In ABAP Connection creat ABAP connection with system with which u want communicate .
Eg I am connection with Systems PB1.
So i developed Connection call PB1CLNT800.
2) In my requirement I have taken data in my context from another r/3,
I have give called RFC in my supply function of node.
Call to RFC is as usual.
In my case,
CALL FUNCTION 'RFC_MATNR'
DESTINATION 'PB1CLNT800'
TABLES
IT_MATNR = IT_MATNR.
Onwards I have read my itab IT_MATNR and populated data to context.
Hope solution will serve your purpose.
Give point if it works .If any problem i have other ways.
Cheers

Making an RFC call from within the VM container

Hi all,
since a long time I am searching for information on how to implement an RFC call from within the VMC. The problem is that we have implemented several (p)functions in ABAP and we need to implement them in JAVA.
Now I am searching for a way how to just call the already existing pfunctions???
Is it possible to read CRM DB tables too?
Thank you in advance
Boris

Hi Freeto,
This may be due to the Network Failures.
If you have triggered a job then because of the Network fluctuations the system may not respond properly and cannot execute the job.
So, this is the cause for the failure.
Hope you understood.

Asynchronous RFC call from R/3

I need to make an asynchronous RFC call from R/3. I receive an error message in R/3 stating that my RFC destination can only be of type I (Internal) or type 3 (R/3 system). In order for it to reach XI I need it to be of type T (TCP/IP). Any help would be appreciated.
Here is the function call.
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK' starting new task 'SESSION1'
   destination 'RFC2XMBSERVICE'
      EXPORTING
           MSG_TYPE            = msg_type
           ORDER_HEADER_RETURN = order_header_return
      TABLES
           RETURNCODE          = i_return.
the RFC desitnation RFC2XMBSERVICE is of type TCP/IP which by default makes it synchronous.
Thanks,
Jim

hi,
have you tried:
CALL FUNCTION 'Z_B2B_R3_FUNCTIONAL_ACK'
in background task
destination 'RFC2XMBSERVICE'
EXPORTING
MSG_TYPE = msg_type
ORDER_HEADER_RETURN = order_header_return
TABLES
RETURNCODE = i_return.
commit work.

RFC call from a Windows Service

Hi All,
I have created a simple windows service which is making an RFC call to R/3 system. This is not working. Whereas the same piece of code written in a windows application projects(exe) works properly. Does anyone had similer issues working with Windows services ? Is it a known issue of RFC calls from windows service ???
Thanks & Regards
Ganesh Datta

Hi Juergen,
After I put the debug statements I figured out that connection to R/3 system is unsuccessful.
I am using the SAP .Net Connector 2.0. I wrote a windows service which is manually started. Withing my service I am using Single sign on to connect .This is what was causing the problem. If I disable Single sign on and supply userID and password then connection is successful and also subsequent RFC calls.
I guess within windows service Single sign on does not work.
Thanks for your reply
Best Regards

Best approach for RFC call from Adapter module

What is the best approach for making a RFC call from a reciever file adapter module?
1. JCo
2. Is it possible to make use of MappingLookupAPI classes to achieve this or those run in the mapping runtime environment only?
3. Any other way?
Has anybody ever tried this? Any pointers????
Regards,
Amol

Hi ,
The JCo lookup is internally the same as the Jco call. the only difference being you are not hardcoding the system related data in the code. So its easier to maintain during transportation.
Also the JCO lookup code is more readable.

Invoke MII Transaction thru RFC Call from SAP

Hi,
We want to get the data from Oracle DB table thru MII (12.0.2).
We need to use RFC call from SAP to MII.
Is it possible to invoke the MII transaction thru RFC by setting in Message Listener?
We have used iDoc messages but not tried with RFC.
How to do that?
Regards,
Senthil

I feel MII doesn't have anything equivalent to RFC in ECC. You may try web services in an ABAP program
Hope the article below helps you

BAPI calling from a non SAP system.

Dear Experts,
I would like to know how can I call a BAPI from a non SAP system, a breif idea/with example ( from any non SAP system ) and sample coding will be highly appreciated.
Thanks, Sudeep..

Hi,
there are couple of possibilities. For example you can export your BAPI as a web service and then use standard tools for web services. There are also libraries to allow RFC calls from different programming languages. You can see all possibilities such as SAP Java connector supported by SAP on https://service.sap.com/connectors. There are also additional libraries not supported by SAP such as SAPRFC extension module for PHP. As you can see there are so many ways how to call RFC enabled FM. You can find examples for each method here on SCN.

Cross reference data from 2 different ecc system.

Hi Sdners,
Iam working on a scenario where i have to get data from two different Ecc system,consolidate them and send it back to their respective system.
But some refernce data in both the systems are different and when iam merging data from 2 system i have to maintain either of the reference data.But problem comes when i syndicate it back to ECC ,it cannot accept a new reference data.
Please suggest me some answere how to proceed in such case.
Its urgent.
Points will be rewarded for Genuine answeres.
Thanks in advance,
Regards,
Neethu.

Hi,
First enable keymapping property to YES for the table which you want to do
importing and syndicatig.
Create two remote systems type inbound/outbound .
Import the data from first remote system and map the corresponding fields.
Don't forget to map the remotekey field which is on the destination side.Make clone
of one of the dispaly field and map to the remote key field.
After importing you can see the records from which remote system are imported
using Edit Key Mappings option in DataManager.It shows that remotesystem
name and corresponding remote key.
Do the same for second remote system too.
After merging data in data manager , you can see the merged record and see the
two remote systems names and two remote keys by using Edit Key Mappings
option so the merged record goes back to both remote systems when you syndicate
the records.
Syndicate the data from first remote system by selecting destination properties and
output remote system property under map properties tab as your first remote
system.
Do the mapping for corresponding fields and don't forget to map the value field under
remote key .Then MDM generates remote keys for only records belongs to your
first remote system.You can see this in destination preview.It does n't genarate
remote keys for second remote system.Then check the option Suppress records
without key under map properties tab and execute the syndication.Finally we can
see the accurate records.
Do the same for second remote system too.
Hope it helps
Cheers

RFC call from Excel using VBA

RFC Call from ABAP (R3) to Webdynpro EP

Hi experts,
I have a requirement to initiate a call from an ABAP program on R3 to a standard Portal (Webdynpro) API. Does anyone have any experience with this?
I understand that normally Portal (Webdynpro) applications will make the RFC call to ABAP via the established JCO connection. However there's very limited literature elaborating how the call can be made in the other direction i.e. from ABAP R3 to Portal
Anyone, please kindly advise how, if this can be done. Many thanks!
Best regards,
Lionel

Hi,
I'm trying to make a RFC call from the ABAP program to a built in Java method residing on EP. It is part of a suite of methods provided by the UME engine.
Typically a call is made from a webdynpro program to a SAP ABAP function module. In this case, I'd like to make a call from the SAP ABAP report to the EP method.
Best regards,
Lionel

Excel sheet generation through RFC call from a BSP application

Hi,
I am calling a RFC FM ( in R3) in Event handler 'OnInputProcessing' of a BSP application in a SRM server.
That function submits a report program which geneates a excel sheet using download FM . Excel sheet is not getting generated.
But when i am calling this RFC FM (in R3) from a report program ( in srm server)
this is generating an ecel sheet.
I want to have call RFC from BSP application.
I tried the way of submit a program ( which contains RFC call) from BSP application ,but it is also not generating excel sheet.
My ultimate AIM is to generate excel sheet by trigerring CALL or submit from BSP
application.
can any one propose solution for it.
Useful answers will be rewarded.

Hi,
Which FM is it. I guess that the download generated is a SAP gui oriented solution, which will never work in a web environment

Setting required to create Business partner record in SAP GTS for the customer who transferred from the SAP ECC system

Dear Experts,
Can you please suggest me list of activities require to automatically create Business partner record in SAP GTS for the customer who transferred from the SAP ECC system .
i.e If I create the customer master record and transfer the same CMR to SAP GTS , what are the setting requires to maintain in SAP GTS sytem to automatically create the Business partner .
Ram

Hi Raghu,
Below are the main settings required to enable you to transfer Customer Master Data to SAP GTS. Please note that their is a difference between, Customer Master Record and Customer Master Data in terms of data and for GTS, we transfer Customer Master Data. Hence, below are the settings required:-
In SAP ECC system:-
Activate the change pointers for Customer Master Data apart from enabling basic connection settings.
Schedule a job to run at regular intervals to transfer all the customer master data for the available change pointers to the SAP GTS system
2. In SAP GTS system:-
Maintain the Mapping for ECC Customers to SAP GTS Business Partners in the General settings area of the SPRO in SAP GTS system
Ensure that the Number range is maintained for those GTS Business Partners.
Also, some time you may be required to maintain the organisational structure to ensure full working.
I hope this will be helpful to you.

Aman

RFC call from ECC to SCM -- Debug Steps required

Hello,
The steps being done for this issue is:-
1) In ECC system ,CN22 Transaction Code (Change Networks) --> Click on Schedule (at the Header) and click on SAVE
2) This seems to trigger an RFC call to SCM server (as per the trace log).
3) From SCM, it comes back to ECC server as User 'BATCHRFC'. This has been defined in SM59 correctly.
4) BATCHRFC in ECC system calls an RFC FM 'CIF_PJ_INBOUND' and changed the status of networks to DSEX (date set by External system)
We are trying to understand why is the RFC call being made? I can debug the FM in ECC when an external breakpoint is used.
However, I want to know where in ECC is the RFC call made (to SCM), and how? How can I control it as we do not want this to happen? How can I debug to understand how an RFC call is made?
Your views would be appreciated.
Regards,
Sanjiv

Hi,
What you do is, enter the Tcode, CN22, then in Command window activate debugger by entering /H
It takes u to debugger, from menu > utilities set a break point at Satetment Call Function, it will stop at all the Function modules in debugger, so you can look for the RFC FM in the program where it is called.
And also look for setting in debugger, may be u have some options for RFC FM.

RFCs calling from remote systems

Hello Abapers,
Can anyone tell me how to find the list of programs which are calling remote function modules? For example programs in CRM system calling function modules in ECC...
Thanks,
Himadama

Hi,
this is only ardly possible depending on your goal.
There are lots of RFC calls especially in CRM for middleware purposes.
Option a) - You try to find all pla ces where z*modules are called that are not existing in CRM
Option b) - You want to find all RFC enabled modules of ERP called in CRM
Option c) - You want to find all RFC calls in CRM targeting the defaulting ERP destination
Solution for a)
- Go to table WBCROSS (which is global the "where used list")
and check for all Z* modules
- Copy the list of modules e.g. in a file
- Search table trdir (registry of function modules) with this list
-> all modules that are not in this list are probably RFC modules from a backend
Solution for b)
- Go to ERP SE37 and open the help
- open the advanced options
- mark "RFC modules"
- search and save the whole list of RFCs relevant
- Go to CRM and check table WBCROSS where these modules are used
Solution for c)
- go to CRM and check for a module called "SMOFERP" or similar
It returns the name of the default RFC destination of an CRm system to its default ERP.
- Check the where used list of this module - should guide you close to the calls
