RFC/BAPI Call

Hi,
I have a basic query regarding RFC and BAPI call.
I wanted to know whether a BAPI/RFC in a SAP system can be called from any other application system or it can be called from only SAP system. Also, what are the sytem/network requirements for such a setting.
Thanks,
Puneet

hi,
Remote Function Call:
RFC is an SAP interface protocol. Based on CPI-C, it considerably simplifies the programming of communication processes between systems.
RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.
RFCs manage the communication process, parameter transfer and error handling.

BAPI
BAPI stands for Business API(Application Program Interface).
A BAPI is remotely enabled function module
ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
You can make your function module remotely enabled in attributes of Function module but
A BAPI are standard SAP function modules provided by SAP for remote access.
Also they are part of Businees Objest Repository(BOR).
BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects.
You create business objects and those are then registered in your BOR (Business Object Repository)
which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA.
In this case u only specify the business object and its method from external system
in BAPI there is no direct system call. while RFC are direct system call.
Some BAPIs provide basic functions and can be used for most SAP business object types.
These BAPIs should be implemented the same for all business object types.
Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs.
Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

RFC/BAPI Call (ABAP Web Dynpro)- DYNPRO_SEND_IN_BACKGROUND

Hi all,
I'm developing an ABAP Web Dynpro application which utilise a RFC enabled function module. When I tried to execute the function module through the browser it terminated with an abap dump. I checked ST22 and found the following dump: 'DYNPRO_SEND_IN_BACKGROUND'. However when I tried executing it using SE37, the function module works fine.
Any ideas?
Ricky

Hello Ricky,
to my guts feeling that should be fine, but I have never used call dialog in such a scenario. If I were in your shoes I would try to break down the problem:
- Is it of general nature?
- Is it specific to this dialog?
To distinquish that I would write the most basic dialog and use it the same way as the target one. If this fails too, using FuBa´s with call dialog seems to be not possible => try to avoid that situation. If the test succeeds, well the hunt for the needle in the haystack is open.
Good Luck
Klaus

RFC BAPI call vs. SE37 execute process differently

I can execute BAPI_PO_CREATE1 using SE37, put a negative value in on the POCOND table, COND_VALUE field, and I get my PO created with a negative discount amount condition record. Yet, when it is called from XI, only a positive value is passed in to the created PO.
While processing goods receipts, I have differences in processing as well.
Are there some flags that need to be set/changed, so that I can call a BAPI remotely and have it process the same way as SE37?

Hi,
Are you putting the sign in front while calling from XI?
there are no separate flags in the code that would make it drop the sign..

Multiple BAPI calls in RFC Adapter

Hi, Dear Friends!
I have asynchronous scenario File to RFC(BAPI).
File contains raws. For each raw I need to execute BAPI.
With the help of each raw I need to construct one document in R/3 database with the help of BAPI.
But now my scenario provide only one document (only one BAPI is executed).
I read file to xml structure. This structure contains elements. The elements represent raws of file. But BAPI is executed only for the first element.
How to explain to XI that I want it impement BAPI N times - as number of raws in file (or elements in xml structure).
So how to implement multiple BAPI calls. Have you any idea?
Thank you in advance.
Natalia Maslova.

RFC adapter Call BAPI error

Hi XIer,
I am using RFC receiver to make a BAPI call, I used a BAPI wrapper due to this BAPI don't have a RETURN structure in the Export Tab which is XI expected.
but after I made a wrapper, the same error occurs, just like I directly call the BAPI without wrapper function. the error as following:
com.sap.aii.af.ra.ms.api.DeliveryException: XIAdapterFramework:GENERAL:com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: failed to parse BAPI response due to: com.sap.aii.af.rfc.util.bapi.BapiException: Parameter with name RETURN not found.

the BAPI name is :QIRF_GET_USAGE_DECISION2
the wrapper name is :ZZQIRF_GET_USAGE_DECISION2
and I added a RETURN structure, type is BAPIRET2.
Please give me some ideas, thank you for your time~~

I still am not sure why you need a Wrapper RFC? If SP 14 or above on XI, RFC adapter have the option of BAPI commit and this will make things easy for you.
You can call the BAPI directly.

Error message in BAPI call

I have imported RFC Interfaces from SAP system. Each interfaces doesn't have fault message.
How to get error message in BAPI call when error occurs?
I can catch an exception in BPM but I need to get error message and send it to another system.

Hi Denis,
>>>I have imported RFC Interfaces from SAP system. Each interfaces doesn't have fault message.
if you want to use fault messages
consider using ABAP Proxies
>>>>How to get error message in BAPI call when error occurs?
most bapis have return table in which they
return error messages (you can do it either
in a sync way or in an async way if the call is too long - with corrlelation of course)

Howto bapi calls

Hello,
I am working on a scenario in which a client (abap proxy) sends a message to the integration server, which dispatches the messages to an rfc-adapter, an bapi call.
Therefore I have read the tutorial, which can be found on this site, but unfortunately I have run into problems. Maybe someone can help me at this point. This is what I did:
1.I have imported the BAPI_FLIGHT_CHECKAVAILABILITY as suggested in the tutorial.
2. I created an Message interface named: U2_BAPI_IF
3. For the output message I have chosen: BAPI_FLIGHT_CHECKAVAILABILITY and for the input:
BAPI_FLIGHT_CHECKAVAILABILITY.Response. I have left the fault message field empty.
4. I did no message mapping, since I want to work with the BAPI Response structure in the abap proxy.
5. The Message interface is defined as outbound synchron.
6.In the Integration Directory I created a Receiver Determination with a Service as a sender, the message interface is U2_BAPI_IF. Additionally I configured a "configured receiver" the client with the BAPI.
7.I created a Interface Determination, for the sender the same entries as above and for the configured Inbound Interface I have chosen BAPI_FLIGHT_CHECKAVAILABILITY and the receiver client
8.I created a receiver agreement.
9. Saved the change list.
10. I have generated the abap proxy for the message interface U2_BAPI_IF, without problems
11. I created the following abap program:
data: lv_msg_raus TYPE ZU2_BAPI_IF_BAPI_FLIGHT_CHECK1,
 lo_proxy TYPE REF TO ZCO_U2_BAPI_IF,
 lv_msg_rein TYPE ZU2_BAPI_IF_BAPI_FLIGHT_CHECKA.
 lv_msg_raus-AIRLINEID = 'AA'.
 lv_msg_raus-CONNECTIONID = '0017'.
 lv_msg_raus-FLIGHTDATE = '20040801'.
 create object lo_proxy.
 call method lo_proxy->execute_synchronous
 exporting
 OUTPUT = lv_msg_raus
 importing
 INPUT = lv_msg_rein.
12. I execute the program and I receive the following error:INTERFACE_REGISTRATION_ERROR, the SAP Stack says:
<SAP:Stack>No implementing class registered for the interface (type ifmmessif, name BAPI_FLIGHT_CHECKAVAILIBILITY, namespace urn:sap-com:document:sap:rfc:functions )</SAP:Stack>
So now my question, do I have to implement a class (proxy) on the receiver side to receive the message and pass it then via bapi call myself, or did I something totally wrong?
I hope somebody can help me,
Thanks
Oliver

Hi Oliver,
I was wondering if you finally got this scenario to work, if Yes. Could you explain how did yo manage to (solve your problem)setup your scenario as described in your earlier note?
Thanks,
Rob.

Problem facing during BAPI call for an inbound interface.

I have requirement where in i need to make a BAPI call from SRM system using RFC adapter.
After importing the BAPI(Z_INV_REF_PO) in the Integration Repository the structure looks to be a follws,
1.Request
2.Response and
3.Exception (fault) Message types.
In my BPM i did a transformation for my source structure with BAPI request. But while doing a BAPI call it throws me Application error as follows,
RFC adapter is working fine.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

<SAP:Stack />
<SAP:Retry>M</SAP:Retry>
</SAP:Error>
Please help me out on this. Itz very urgent

Hi,
As the error is Applcation_error, the data reached the target system but the BAPI call fails. So you mignt not be providing all the mandatory fields to the BAPI.
Perform a standalone testing of your BAPI, with the data being passed from XI See if the BAPI call is successful..
Hope this helps you.
cheers,
Siva Maranani.

RFC function call from VB Script

I have an RFC enabled function that I need to call from VBScript. I was working through this issue as a BAPI call but after research and RFC not initialized error messages over and over I am coming to think that the issue is not how I was doing it but what I was trying to do with different objects.
I think the issue is that I was trying to call a RFC function with BAPI methods, I didnt understand that there was I difference but now I do. I don't know how to initialize the RFC on the host system and unsure if I even have all of the components on the host system to make these function calls.
The goal here is to call a function that passes 3 paramters and modifies a user object in SAP.

Hello John,
are you using DCOM Connector? I have a VBScript working correctly, using DCOM Connector, and consuming a Z function module defined as RFC.
What's the error message you're getting?

Michael

Diff... between ALE, IDOC, RFC, BAPI, BADI --- Not clear and clarify

Hi All
    I am learning XI and the difference between " ALE, IDOC, RFC, BAPI, BADI "
    Not clear and when to use what and how in point of XI ?
   Pl..clarify me
Adv..thanks and points
--- Rakesh Behera

Hi
This will expalin you every thing ...pl..go through
The interface concept of the classic R/3 is based on two different strategies: Remote Function Calls (RFC) and data exchange through IDoc message documents. RFC makes direct and synchronous calls of a program in the remote system. If the caller is an external program it will call an RFC-enabled function in R/3 and if the calling program is the R/3 system it will call an RFC-function in another R/3-system or it will call a non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.
IDocs are text encoded documents with a rigid structure that are used to exchange data between R/3 and a foreign system. Instead of calling a program in the destination system directly, the data is first packed into an IDoc and then sent to the receiving system, where it is analyzed and properly processed. Therefore an IDoc data exchange is always an asynchronous process. The significant difference between simple RFC-calls and IDoc data exchange is the fact, that every action performed on IDocs are protocolled by R/3 and IDocs can be reprocessed if an error occurred in one of the message steps.
While IDocs have to be understood as a data exchange protocol, EDI and ALE are typical use cases for IDocs. R/3 uses IDocs for both EDI and ALE to deliver data to the receiving system. ALE is basically the scheduling mechanism that defines when and between which partners and what kind of data will be exchanged on a regular or event triggered basis. Such a set-up is called an ALE-scenario.
The philosophical difference between EDI and ALE can be pinned as follows: If we send data to an external partner, we generally speak of EDI, while ALE is a mechanism to reliable replicate data between trusting systems to store a redundant copy of the IDoc data. The difference is made clear, when we think of a purchase order that is sent as an IDoc. If we send the purchase order to a supplier then the supplier will store the purchase order as a sales order. However, if we send the purchase order via ALE to another R/3 system, then the receiving system will store the purchase order also as a purchase order.
I hope this will help you to understand the difference bet..those

Minimal Authentication for BAPI calls

Hi,
We use SAP Jco Library to connect SAP systems in our applications. Within the aplication we make BAPI calls to the SAP system for various operations. A typical BAPI calls we make are BAPI_DOCUMENT_CREATE, BAPI_DOCUMENT_GETLIST, BAPI_EQUI_GETLIST etc.
For these BAPI calls it is must that the user needs SAP_ALL and SAP_NEW profile added to his profile. I would be interested to know what is the minimal profile the user needs to make these BAPI calls?
Is there a document/link which talks about the minimum roles\profile needed for different BAPI calls byt the user.
Regards,
Naveen

there's a couple of notes on that:
[452508|https://service.sap.com/sap/support/notes/452508] describes RFC-connects coming from a portal.
[129795|https://service.sap.com/sap/support/notes/129795] does the same for connect via Session Manager
... there are a couple of others - a quick search in SMP will reveal the others.
as for your BAPIs: obviously you will need the authorizations for whatever the BAPI wants - some BAPI's require transaction code, several organisational values - e. g. creating CS-orders uses most of the I_* objects as well as the t-code for IW31.
But that is about all - you do not need SAP_ALL and/or SAP_NEW - in fact: try to avoid it - reduce the RFC-users to what they need and no more. Keep to using BAPIs for your development, as they are much more trustworthy (securitywise) than other RFC-FM's/methods.
In the SDN security forum are some sticky threads where you might find additional information in that direction. Its worth a look, Julius goes to great length of pain to make them interesting.

Regarding the BAPI calls without input

Hi all,
We are developing on webdynpro component. I came across a scenario where we call the BAPI through Adaptive BAPI model. This bapi doesnt take any input parameters but returns 7 tables with data.
So, My problem here is i am not getting output in the 7 tables. i am sending a dummy input and executing on the input elements modelobject.
Could anyone ddid this scenario.. ie., calling/executing teh BAPI call which doesnt have any input s but expects output.
Here is what i have
Z_Sales_Order_Header_Input bapiSalesOrderHeader=new Z_Sales_Order_Header_Input();
wdContext.nodeZ_Sales_Order_Header_Input().bind(bapiSalesOrderHeader);
wdContext.currentZ_Sales_Order_Header_InputElement().modelObject().execute();
int ilSalesOrderTypeSize=0;
ilSalesOrderTypeSize=wdContext.nodeZ_Sales_Order_Header_Output().nodeSalesordertype().size();
Thanks & Regards,
Raghavendra Pothula

Hi Raghavendra,
If I read you correctly, you are printing the size of the root output node (Z_Sales_Order_Header_Output) and not that of the output node inside your 'Z_Sales_Order_Header_Input' node. When you execute the RFC, the output node inside the 'Z_Sales_Order_Header_Input' node gets populated. so try printing the size of the 'Salesordertype' node inside the 'Z_Sales_Order_Header_Input' node.
-Z_Sales_Order_Header_Input
---output (this is the default name)
---Salesordertype
Infact there is no need to create the 'Z_Sales_Order_Header_Output' node itself in the controller or view.
Hope this helps,
Best Regards,
Nibu.

How to transfer range parameter from vb when using bapi calling

Hi,everyone.how to transfer range parameter from vb when using BAPI calling?

Did you get the solution to your problem? Can you please share it with me. I have a similar problem. I have a VB program that calls RFC function. It works with a single parameter but not with a range of parameters. If you have the solution, could you please share sample codes with me? Thank you so much.

Two bapi calls in the same session using PI

Hi,
I have a file to RFC scenario wherein I need to call a BAPI (L_TO_CANCEL) and then again, I need to call another bapi called
"BAPI_TRANSACTION_COMMIT" in the same session. My question is, if I use RFC adapter, do I have to call the commit bapi again?
If yes, is there anyway I can do that ?
I believe that will be the case only if I use a proxy. Is that correct ?
The requirement is to call these two BAPIs and finally include a success or error message in the response.
Thanks.

Inside the BPM you do not have a specific exception message. You can do an exception handling based on the exception, but the excpetion itself is not a real message.
If you want a real message, you could create an ABAP proxy, which has a message like this:
root
- part1
       - rfc response
   - part2
        - error text
then you can split this inside BPM and send a the response or the error.
Of course there are other possible solutions.
