RFC enabled function module and BAPI?

What is the difference between RFC enabled function module and BAPI?
I have requirement to develop a new BAPI which will update a custom table and read the same table in SAP from an external application.
Do we need define a port or RFC destination for the external application to use the new BAPI?
I am clear how the external application access the BAPI.
Thank you

BAPI are business objects which are basically object oriented. Created and linked with business objects in SWO1. Those business objects will be listed under BAPI tcode.
Where are RFC enabled Function call are not like that. They are just Function modules which can be accessed remotely from an SAP application.
For your example updating table, you may need to create BAPIs in SWO1 and access using those using object oriented methods from external application.
Cheers,
Thomas.

Converting a RFC enabled function module to a webservice

Dear Experts,
Greetings.
I have created a RFC enabled function module and I would like to convert this into a webservice. When I try in SE80 ...it says Webservice created but in WSCONFIG I am unable to access the created webservice....Any clarification on this regard?
Thanks in advance.
Regards
Sathya

hi
you need to follow some steps for the above said requirement:
1. you need to set FM as RFC enabled
2. now go to SE80, and open BSP application WEBSERVICEBROWSER.
3. just activate this application here.
4. choose search.html page in this application, and choose teat option from the context menu
5. enter the Function module name in the page displayed.
6. Here it will give us the WSDL link for this fm
7. use this link to call the web service, which in turn calls your FM.
hope this heslps

RFC enabled function module to insert , update and delete data in a ZTABLE

if not how can we create it? plz give me the details steps..
what are the import, export parameters and how to code and process it.. (for example: suppose fields in the table is Emp_Id, Name, Address. I need to develop a RFM which does the 3 tasks, insert update delete in the same RFM)
Thanks and Regards

create a f.n mod in se37 and make it rfc enabled. ur import parameters are Emp_Id, Name, Address and TASK and u can have an export parameter like result which gives the status of the update. based on task u can insert using keyword INSERT....and update using UPDATE or MODIFY and delete using DELETE. these keyword are not compelte with syntax but need to refer the SAP documentation.

RFC enabled function module using call transaction

Hi,
We have a scenario wherein we have a RFC enabled function module which inturn uses a call transaction to create a PM order & attaches the PM notification against it. Sometimes it so happens that the order does not get created for some reason or the other and there are no logs generated on the system to investigate. However we are capturing the messages produced via the BDCMSGCOLL. At present we are using the update parameter as 'L'.
In some scenarios it states that the notification is locked by the same notification and comes out without creating the order, in this process we are losing out on the order & the notification number which if successful would have got updated in the database.
I know this could be done via the BAPI, but there are innumerable steps within the BDC which can't be actually done using the BAPI and hence we could not use this procedure.
Is there any other way by which we can ensure that there's always a successful order creation, I mean without losing out on the order/notification number?. Would changing the update mode to 'S' help?. Since this process is time bound, it can't actually take more time then what its taking with the current logic.
Please let me know if you require further details on the same. Any help in this regard would be highly appreciated.
Regards,
Vidya

Sorry for an unclear replay.
In Simple terms; I have 2 scenarios;
Launch a new tab (IW38 tcode), on click of a button in SAP screen of custom transaction in NWBC.
Launch a new tab (IW38 tcode), on click of a button in a Non - SAP App opened (using URL) in NWBC.
For 1st case, i have used
CL_NWBC=>URL_CONSTRUCT
EXPORTING
     CANVAS_WDA__CLIENT_TYPE       = 'nwbc'
     CANVAS_TRANSACTION            = 'IW38'
RECEIVING
     URL                           = lv_URL.
CALL METHOD CL_NWBC=>URL_LAUNCH
   EXPORTING
     URL    = lv_url
But it gets open in NWBC HTML not in NWBC Desktop client.
I tried all the Parameters you have mentioned in your response to this post earlier, but nothing worked. the last one is CANVAS__WINDOW which actually hides the top area and few buttons but still it is a HTML version.
If i set the HTML_CLIENT = ABAP_FALSE, it launches a new window instead of the tab and asks for Login. If i login in can see the IW38 in NWBC desktop client. But the only problem is we have the restriction of single window/single login for users.
I am on NWBC PL12 and also updated the GUI 7.3 to PL8.
Simply the problem is URL_CONSTRUCT for any transaction is launching it in a new tab but in HTML Version.
For 2nd case,
It asks for the login details on click of a button on the 3rd party URL opened in NWBC. which means i am launching SAP from a 3rd party.
Is there any way to achieve the launch of new tab in this case instead of the new window ?
I hope its more clear now.

Nik.

What is the difference between the normal function module and bapi function

hi,
what is the difference between the normal function module and bapi function module.

Hi
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.

Anji

Problem with String parameters while Calling RFC enabled Function Module

Hi all,
I execute BAPI(RFC enabled Function Module) from my WebDynpro Application and retrieve data from R/3.
To fetch the data I pass few String parameters to BAPI from my Dynpro Application.
Now the problem is that while making this call, the parameters are automatically converted to UpperCase. And I want those parameters in the original case at R/3.
I am not able to find out whether this conversion occurs at Dynpro side or R/3 Side.
Should i configure my BAPI(RFC enabled Function Module) or is there some option on the Dynpro Side to preserve the Case of the String?
Please help me.
Thanks,
Darshil

Hi Darshil,
I'm not sure whether you have experience with ABAP or you are a Java Programmer, but we cannot set that flag permanently.
Now, if you are saying that the domains are marked with the Lowercase attribute, then it means that the final table field will be capable of holding Case Sensitive data.
I have a hunch that the case-conversion is happenning at the Web-Dynpro side. Or, the application logic converts the string to UPPERCASE explicitly.
By the way, which BAPI are you talking about ?

Anand Mandalika.

How to call a RFC-enabled function module

Hi All,
We have 2 systems; system 1 (client 420) and system 2 (client 600).
I just want to know that how can a RFC-enabled function module be called from one system (420) whereas the RFC-enabled functio nmodule exists in the other system (600).
Also, as per my understanding any RFC-enabled function module is a BAPI. Please confirm.
Please help.
Thanks & Regards,
Namrata

Hi,
RFC enabled FM can be called from anther system:
From 420 we can call RFC FM residing in 600, through RFC destination cretaed in SM59 tcode in 420 client.In sm59, maintain the entries of destination system i.e 600.and test the connection whether it is succesful or not/ through remote logon.
suppose in 420 client , in sm59 u have cretaed with destination DEST600 say.
In 420, u can code as below..
Call 'RSSDK_LOGSYS_REMOTE_CHECK' destination DEST600

there exist difference between BAPI/RFC.
BAPI always return messages / RFC doen't.

Exposing an RFC-Enabled Function Module as a Callable Object

Hi All,
I'm creating a GP Process based on the Exposing an RFC-Enabled Function Module as a Callable Object Tutorial. I'm using the error handling through a structure, the RFC works perfectly when I run it in test mode and the RFC doesn't retrieves exceptions at the structure, but when an error/exception must be returned at the structure, the test is showing this message (and also is not returning any error at the structure):
"Process exception occurred" and "Callable object implementation did not return output parameters".
What can be happening?
I'll appreciate a lot your help, regards,
María Margarita Monteverde

Hi,
Thanks a lot for your answer. My scenario is very simple :
1) the first callable object contains a web dynpro form where user can enter an ID, a name, and other informations
2) the second gets the output parameters of the first step and execute the BAPI_FLCUST_CREATEFROMDATA to add the row into the SCUSTOMER table
The problem is that no row is added. I can integrate BAPI wich allows to read data, but when I try to write (create or change) I cannot see any change.
Do you see my problem now ?
Regards,
Michael.

Difference Between Function Module And BAPI

Hi Friends,
What is the technical difference between BAPI and Function Module (Normal, RFC and update)?
When do we use BAPI and FM?
If BAPI is also RFC enabled then why do we have RFC function module?
Kindly clarify with examples.

Hi Pradeep,

RFC enabled function module is not runing the BDC code in it.

Dear Experts,
1. We have created a RFC enabled function module to change status of a activity and to save it we are using BDC code and we have also put the code in the RFC FM only.

Dear experts,
Already the FM is RFC enabled other i won't be able to call it from portal
and coming to using the BAPI_ACTIVITY CHANGE fm that acting very weird so we are using the CRM EXTERN CHANGE USER STATUS fm which is working fine but the only problem is even when we comit from BAPI_TRANSACTION_COMMIT its not getting the delta queue of BW updated eventhough its chaning the status.
So for the above reasons we are using the BDC code in the FM for pressing the save button then its will update the changes to BW delta queue as well.
its working fine when i run it from the system in tcode SE37 only the BDC code is not runing when i am doing it from portal apart from the fm is chaning the status .
thanks and regards
Neel

How to call Custom RFC enabled Function Module in R/3 From XI

Hi Experts,
I want to call custom RFC enabled Function Module by sending some input parameters from XI.
How to do this
Thnx
RAMS

Hi RAMS,
1. Under the SWCV Go to the Imported Objects.
2. Right click on the RFC and click on the Import of SAP object.
3. Give the logon server name, system number the user name and pasword.
4. Select the RFC u want to import.
5. Execute the import and the RFC is imported under the SWCV.
Now u can use this Imported RFC in the scenarios of that SWCV.

RFC enabled function module which will be called from XI

Hi Abappers,
I have to send confirmation of the sales orders created by inbound Idocs ORDERS05 to XI. For this I have to use outbound Idoc ALEAUD01. But since I also need to send NETWR(from VBAK) and there is no field in this Idoc for that,
I have to develop an RFC enabled function module for which a RFC lookup will be performed from XI. This function module has to return NETWR values for sales orders. Can anyone please tell me how to go about with this function module.
Thanks in advance.

Hi Priyanka,
Add a parameter in tables tab of function module with reference to NETWR. It'll work.

List of RFC enabled Function Modules?

Hello,
this might be a tricky one - would anyone know if there is a way to get a list of all RFC enabled function modules in the basis area?
I know about se 37 and it's search functions but would like some type of "all" list.
Thanks for thinking.
Andi

check table..
TFDIR where FMODE = 'R' then u will get all function module that are remote enabled.
