Call external RFC in a workflow

Hi!
I'm going through the tutorials at
http://help.sap.com/saphelp_46c/helpdata/en/fb/1359c4457311d189440000e829fbbd/frameset.htm.
I had a question - as one of the steps in the workflow, is it possible to call an RFC on an external system (a destination defined via SM 59), get the response back, and use that response in the next step in the workflow, which again calls another RFC on an external system?
Thanks,
Mustansir

Yes, you can achieve that by using the corresponding methods of the activity defined.

Call an RFC as a Workflow step

Hi,
I need to integrate inside a workflow (designed via Process Composer) a call to a backend RFC.
In detail, I need to make a callback to the backend when a process is created to register the successful creation of the process itself.
So it should be something like this:
START --> AUTOMATED RFC CALLBACK --> Workflow tasks --> END
I'm trying adding an EJB and linking it to the workflow with a Mapping Activity, but I'm not sure that I'm doing the right thing.
I've found a SAP guide that shows how to call an EJB from a workflow with a Mapping Activity but I'm having problems making things work.
Can someone suggest me if this is the right way to get the things done?
As a side note:
I work in a multi-track development environment. Every track has inside a project representing a specific workflow. Could it be possible to have a single EJB, placed in a track, to handle all the callback request from all the workflows from different tracks?
Thank you,
Pietro

Hi,
a little update...
I've made the EJB work! This is an excerpt of the code:
@Stateless
public class ActivationCallbackBean implements ActivationCallbackLocal {
     // FUNCTION NAMESPACE
     private static final String NAMESPACE_FUNCTION_PARAMETER = "mycompany.com/mctfc_invoice_approve";
     // PARAMETER NAMES
     private static final String P_ID = "ID";
     // PARAMETER LOOKUP NAME
     private static final String NAME_PROPERTY_INPUT_ID = SdoRenamingHelper
     .renameXsdElementToSdoProperty(new QName(
               NAMESPACE_FUNCTION_PARAMETER, P_ID), false);
     public DataObject invokeSdo(DataObject input, InvocationContext invContext) {
          boolean isBackendCallSuccessful = true;
          Type typeInput = input.getType();
          String id = input.getString(typeInput
                    .getProperty(NAME_PROPERTY_INPUT_ID));
Now, as I said I have multiple workflows and I'd like to have only one EJB to handle all the calls. In order to do that I've added a special input parameter to discriminate which workflow is the "caller". But I've got a problem. When I define in Process Composer an EJB Function under "Rules and functions" in order to point to the EJB, i got a fixed value for the namespace.
Since the namespace is mandatory to retrieve the input values in the EJB and the namespace is based on the workflow I'm working with:
NAMESPACE_FUNCTION_PARAMETER = "mycompany.com/mctfc_invoice_approve";
(mctfc_invoice_approve is the name of one of the workflows) what can I do to have only one EJB and overcome this limitation? Is this possible?
Thank you,
Pietro

Calling External Web Service from Workflow

Hello Gurus,
I'm working on a workflow development in which I have to invoke an external web service (non-SAP) from a workflow task. As soon as the work item is created in SAP, I need to send a notification via web service call. So I thought of having a workflow step to call the web Service.
(1) Can I use WF_EXTSRV wihout having a BSP application.? There is no BSP application in my case.
(2) What are the possible options I have to achieve this?
Thanks
Steve.

Hi,
I don't see a reason why you should necessarily use WF_EXTSRV.
Just create ABAP class in SE24, for example ZCLASS. Add interface IF_WORKFLOW to the interface tab. Implement the interface methods. Actually you don't really even have to implement them, just go into the methods and activate them. Now you have a workflow compatible ABAP class.
Now create new static&public method to it, for example CALL_WEBSERVICE. Add any importing and exporting parameters that you need (what info you need from workflow to call the web service and vice versa). Code your web service call from this new method.
Create new task in PFTC. Call your new method ZCLASS->CALL_WEBSERVICE. from the task. Add the task as a new step into the workflow in a suitable place.

Karri

Not able to call External (RFC) Service in CAF

Hi,
When trying to import RFC(ABAP) in CAF for External Service using the wizard, after I give the SAP Logon Information nothing happens Wizard does not move to the next screen after I give the logon credentials and SAP System Data,
I tried with Single Server and Load Balancing but nothing happens on clicking Next button, moreover when I try to login to SAP system from backend I am able to login on giving logon credntials.
Pls suggest what could be the problem.
Vishal

Hi,
Have u tried ny using IP address in the place of host name? If not the please try it.
If you have alrady done then do the following
First of all close the NWDS and take the backup of your important projects from workspace. Then delete the .metadata folder from workspace. Now open the NWDS and try to create a new CAF project and try to import again. I think it will work.
If any issue please let me know.
Thanks

Contents in the parameters have been shifted when calling external rfc

Dears,
when i use ' call <FM name> destination <destination name> '
the contents of paramters are shifted when reaching .net RFC server .
and when i transport my program to QAS server, it is ok... all the seting of program and destination are the same . .net server use SAP connector to communicate with SAP
any one encounter such problem ? what maybe the reason ?

Do not worry. It is probably a permission you should ignore, but you should check that the permission appears in this site > http://support.apple.com/kb/TS1448?viewlocale=en_US&locale=en_US

How to call a RFC function from ABAP to external C/C++ system

Hi
Can some one describe me what are the steps that needs to be done to call a RFC function in external C++ system and to handle errors.
Any previous experience,please share

Hi,
i think this is the wrong Forum.
Better use the SAP NetWeaver .NET Technologies Forum on this site.

Reset or Clear SAP user context by external RFC caller program

Hello,
I have a SAP system with performance problems due to a SAP user context starts using a lot of memory.
This user context comes from an External RFC caller program written in Delphi and which uses the SAP RFC SDK provided by SAPGUI 6.40: SAP Automation library, SAPFuntionsOCX, I mean, using methods in the object "SAPFunctions" in SAPFunctionsOCX in file "wdtfuncU.ocx", in SAPGUI directory.
Everytime we have performance problems, this RFC SAP user context is using near 1400 Mb of extended memory, although there is a lot of free physical RAM memory available, there are free dialog processes and CPU load is low (no more than 30%).
This performance problem is solved by closing the external program (written in Delphi) which connects to SAP via RFC.
This external program works for the warehouse management and connects to SAP several times per minute. Due to connection performance and the high frequency with which this external program must connect to SAP, the connection to SAP is not closed after each call to RFC SAP function modules.
The extended memory used by this SAP RFC user is growing along time. I detected, using ST03 transaction, that these user sessions have always the same transaction code hash, I mean, although the external programs call the same SAP RFC funcion modules several times (¡¡¡ always clearing the variables at the beginning and at the end of de ABAP code, with ABAP commands like REFRESH and FREE ¡¡¡¡) the technical transaction code is the same and I suppose the user context (in extended memory) is not deleted.
I think it is better than the external program close the context memory (similar to "/n" okcode in SAPGUI).
But we don't want to close the connection, because the external program connects to SAP with a high frequency, and the logon process is expensive.
Is there any way to send something similar to "/n" (end of transaction) from the external program? Is there any command in the SAP RFC SDK library (SAPFuntionsOCX or something similar?
I cannot find any method to do that in the object "SAPFunctions" in SAPFunctionsOCX in file "wdtfuncU.ocx", in SAPGUI directory.
Old information for Object Classes "SAPFunctions" in SAPFunctionsOCX in file "wdtfuncU.ocx", in SAPGUI directory, is described in the following URL:
http://help.sap.com/saphelp_45b/helpdata/en/39/7e00d1ac6011d189c60000e829fbbd/frameset.htm
But I cannot find anything related to something similar to a "/n" in SAPGUI.
As I have the SAPGUI installed on my desktop, I can see all SAP RFC classes and methods from Excel, by opening the Visual Basic editor.
I am only asking a way to send to SAP a command to free the user context used for an open RFC session in order to avoid the memory used to be continuously growing, without having to close the RFC session.
The external program only calls a certain SAP function module periodically and we want to free the user context between calls without logging off. This is the same, very similar, as if we called that function from SAPGUI and we used "/n" in SAPGUI between calls.
Anyone can help me?
Thanks and best regards.

Hello,
I don't know if this will solve your problem, but you may be using MF 'RFC_CONNECTION_CLOSE' between each call of you RFC function.

How to prevent simultaneous external RFC calls

Hi all
We are facing some problems when external systems are caliing one of our RFC's simultaneously.
Is there a way to prevent and RFC to be called simultaneouslly?
Thanks a lot for your support.
Rui Simões

Hi,
We cannot stop external systems to call the RFC. They will call at their own leisure.
However, so as to keep a check so that processing time does not get wasted,
and if we want that only one can call the RFC at a time, we can write some
code inside the RFC.
For this we can create a z lock object and lock it inside the RFC. Just before the last line of the code, we can unlock it also.
In the middle we can write the code that if the lock object is already locked, then it can exit and can return some error message.
But by doing this, it may impact the understanding of the existing RFC by the external system.

Amit Mittal.

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.

Please read the forum rules about u r g e n t ...

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.

Julius

Error in Mapping of external RFC reponse

Hi experts,
I have big problems with my current scenario. I tried to call a C-program by using RFC connection.
synchronous RFC scenario:
request:
Sender SAP-System RFC-Adapter> XI RFC-Adapter> receiver C-program
on both sides I use RFC-Adapter and the flags of unicode is also set,
on sender side I have created a simple RFC adapter, this side works without problems.
On receiver side I have create an external RFC call. Here a RFC destination which is created on my SAP XI sap Gateway is invoked by the RFC Adapter. My C-program registers the program id of this RFC at receiver side. So by testing the RFC connection (transaction SM59) the RFC works fine.
The request mapping includes on both side the same RFC-structure.
response
Sender SAP-System <RFC XI <RFC receiver C-program
The response mapping includes on both side the same RFC response structure.
When I execute my scenario by calling the ABAP-Program in my SAP system, it seems that request works fine, but during the response in the integration engine following error occurs:

How to call Asynchronous RFC

Hi Everybody,
 Could yo pls guide me on how to implement asynchronous RFC. When i run my RFC using Report :
CALL FUNCTION 'Z_HR_NO_ALTINN_TX' DESTINATION 'Q3A2X7A'starting new task 'test'
exporting
 PASSWORD = 's'.
I get the error saying :
What happened?
 When executing the asynchronous RFC, the RFC destination "Q3A2X7A" had
 neither an internal (connection type 'I') nor an R/3 communication
 type (connection type '3'.
 Error in ABAP application program.
 The current ABAP program "Z_ALTINN_TEST" had to be terminated because one of
 the
 statements could not be executed.
 This is probably due to an error in the ABAP program.
Error analysis
 A typical cause of error is the
 execution of external programs (RFC destinations of the type
 TCP/IP) via asynchronous Remote Function Call (RFCs with the
 addition 'STARTING NEW TASK taskname').
 RFC destination... "Q3A2X7A"
I would like to know if async RFC call is possible to XI.

Raj

Hi,

Calling Adobe form in a Workflow Step for approval

Hello,
There are some ISR forms and workflows in MSS which use Workflow tasks configured as JavaWebDynpro to call Adobe form from the Workflow Step.
Is it possible to achieve the same using ABAP Web Dynpro and creating a new task and configuring to use it as an ABAP Web Dynpro (which can in turn call the Adobe form from the WD)?
Thanks.

Hi Anjali,
1)You can develop an RFC that collects required basic data from R/3 and display them in ABAP WD - Adobe Form. The End user can change/fill the remaining contents of the Adobe Form and submits it for approval. The RFC again handles the triggering part of the Workflow and passes the form data to the workflow containers.And for approvals, you can use the SWFVISU to call a ABAP WD application from Workflow. And in turn the control again goes back to RFC and so...
2)I dont have much idea in ECC 60 if there is a similar ABAP WD application like Standard Java WD IsrFormApprove.
3)No idea.
Regards,
Raja Sekhar

Is BAPI_TRANSACTION_ROLLBACK supported in external RFC applications?

Hello,
maybe someone could shed some light into this.
I am writing an external RFC client application using library librfc32.dll. The application calls a custom RFC module, which inserts a record in a custom Z* table. This RFC module does not invoke, explicitly or implicitly (at least, not that I am aware of) the COMMIT WORK operation.
After this RFC module call the RFC/BAPI module BAPI_TRANSACTION_ROLLBACK is called. The intent is, of course, to rollback the operation from the previous RFC call. Yet the rollback attempt fails and the inserted record is not removed from the table.
An ABAP program making the exact same calls to those RFC modules, however succeeds.
Has anyone an explanation for this behavior? Thank you!

Hi,
In case of a WARNING message, the ROLLBACK wont happen automatically whereas in case of an ERROR message, the ROLLBACK would happen.
But to be on safer side, it is always good to call BAPI_TRANSACTION_ROLLBACK irrespective of the message type ( Warning or Error).
Same is the case with COMMIT. If you dont give an explicit commit work, the data would be COMMITED once the transaction/process is completed without any error/warning messages.
Best regards,
Prashant

How to send an idoc of lower release to an External RFC server

Hi All,
I am sending idocs from the sap system to an external rfc server(written using Sap RFC SDK).
When an idoc is sent from the Sap system, I receive an IDOC_INBOUND_ASYNCHRONOUS call in the external RFC server with the Idoc data.
Everything works fine with the latest release of idocs. But if I send an Idoc of lower release number, I am getting the data records properly for the lower release(say 640). But the DOCREL field (in the control record- EDI_DC40) always gives me the latest release number(700)
In my partner profile, I specify the Segment release number to 640 and even then I am receiving the value 700 in DOCREL.
What am I missing here? How can I populate the DOCREL field with the appropriate release number?
Any help would be greatly appreciated.
Thanks
PS: Please feel free to move this post to appropriate category, if this is not the one.

Serigo,
Thanks for your reply and we are not using XI.
I have defined in the port definition giving the path name refering to unix like /outbound/<system name>/<directory name>. But I dont know how to define for C:\temp\, if I define the same way as c:\temp\ do I need define anything anywhere else ?
Kindly let me know.

How to Debug Functional Module called via RFC?

Hi Experts,
     Please, can someone explain to me how to debug functional module that is called via RFC? Thanks in advance.
Best Regards,
Aleksandar

Hi Laxman,
   First of all thank you very much for giving attention to my post. Ok, I am trying to debug function module in RM-CA (FICA), function module is called by CRM system (via RFC) and in addition all this chain is triggered by WebClient.
     I have user that can login on the CRM as well as on RM-CA (ECC 6.0) system, but those users are different (unfortunately I do not have administration permission so I cant change profiles of my users but I can ask for it). I can without any problem debug calls that come from WebClient, so setting an external break point in CRM system I can catch whatever I want but when process comes to point where actually call to back-end (RM-CA) takes place I simply cant get into functional module, that resides on RM-CA side. Actually what happens is that processing continues as was chosen NEXT STEP (F6).
     To resume, two systems and two different users. Where XCM user should be created? (on RM-CA system or CRM). Should I change something in Menu option Utilities -> Settings -> ABAP Editor tab -> Debugging tab, in field users? If you need any additional info please tell me.
Thanks again for your support.
