Creation of RFC function module

Hi experts,
My requirement is, an XML file is coming from non sap to middleware in XML format. Middleware converts it into sap format and it will access the RFC, i.e., BAPI, which will be created by me and updates the same in CRM.
There is one mapping sheet given, ie., from source format to destination format.Now the point is, for creation of BAPI, what should be taken as parameters, ie import, export etc., Can I take the destination fields as importing and table parameters? Please suggest
Rgds,
Gsaasg.

Hi,
If I understand your requirement correctly, you want how the mapping file will be used to decide the import and export parameters of your BAPI.
Though we should have a look at the mapping sheet, but it is more useful to the middleware person. The middleware person will use them to create a mapping on their side. Once teh data from legacy will be received by them, those data will be mapped to respective SAP format. This format will be shared to them by you.
Let them know of your import parameter details, and what data you expect in each field. This will help them map the data correctly.
We should create the standard ABAP structure as per the data coming in XML, and should be used as the import parameter.
For ex:
if the XML file is:
<ContactInfo>
       <address>
           <city>XYZ</city>
           <postcode>ABCDEF</postcode>
        </address>
         <Number>
               <type>Mobile</type>
               <No>0123456789</No>
          </Number>
</ContactInfo>
then we have to create a structure as ZCONTACTINFO, with two components ADDRESS and NUMBER.
ADDRESS will be of structure ZADDRESS with two components CITY and POSTALCODE.
NUMBER should be of a table type with line type containing TYPE and NO. (as Number node can contain multiple entries..one for mobile, one for home, one for office)
And this CONTACTINFO will be the IMPORT parameter in your RFC FM.
In your case, no export parameter is to be maintained. Only thing is that we should understand the XML well.
Hope this clarifies your case.

Problem in the creation of rfc function module

hi,
I am creating one rfc function module comparing to standard non-rfc function module. In that one i have one export parameter with the standard strcture type. but this stcture component contains with strcture type. among all these components four fields are common. but when i am trying to activate function module it is giving message you cannot use internal tables, strings,references, or strctures as components. that function module name is BAL_FILTER_CREATE and that export parameter name is that export parameter name is E_S_LOG_FILTER that associated type is BAL_S_LFIL. how can i solve the problem. pls give me solution as soon as possible.

hi,
for rfc fm's u should enable the call by value check box which will appear on that of import and export parameters. tick that one for each parameter in rfc and activate.
if helpful reward some points.

Call RFC Function Module and return 1000 records at a time

I would like to call a Remote Enabled Function Module from a non SAP system. This function module will select data from the database and return it to the calling program.
Suppose there are 100,000 records that need to be returned, but the calling module would like the data in chunks of 1000 records. Therefore the calling program would call the FM 100 times.
How do I code the function module to know on each subsequent call to grab the next chunk of 1000 records?
Let me know if additional information is needed.
Thanks,
Aaron

Hello,
Here is how you can go for this issue:
1. Create one RFC function module with following parameter. These parameters are with respective of chunking logic.
     Import: Package Size
     Export: Total number of records
     Changing: chunk count
Implement following logic:
1. First of you need to know how many chunks you need to fetch for that get the count of total number of records. This is one
    time activity so you better maintain one flag import parameter will be set to 'X' only first call.
2. Get the number of chunk using total number of records / chunk size for e.g. 1000 / 100 so chunk count = 10.
3. Define internal chunk counter in function module which will be used to locate the correct chunk depending on the chunk
    counter value sent from calling program.
4. Send first call with package size 100 and chunk count = 1, execute select statement and increment internal
    chunk count check if chunk count = internal chunk count in current case chunk count = 1 so exit select statement and return
    with first chunk.
5. Send second call with package size 100 and chunk count = 2. Execute select statement and check chunk count with internal
    chunk counter, in current case it will be 1 so skip that data and go for next chunk of 100 records increment internal chunk
    counter. In this case it will match with external chunk count = 2. load output table with that data and return to calling program.
6. Repeat step 4 until you reach last chunk.
You need to use SELECT...ENDSELECT with PACKAGE SIZE addition so for every loop it will return number of records mentioned in package size.
Hope this helps.
Thanks,
Augustin.

Help in Creation of a Function Module.

Hi Abapers,
                I am new to ABAP and hardly have knowledge abt it. I need to create a Function Module which is of the type RFC. Pls provide me information and steps to create the same.
Many thanks in Advance.

Hi Pooja,
Please follow the below steps to create a function module :
1. Goto Transaction code : SE37.
2. Create a Function Group first.
   a) From the Menu Bar Choose Goto -> Function groups -> Create group.
   b) Specify the function group name and a short text.
   c) Choose Save.
When you create a new function group, the system automatically creates a main program containing two includes. Like any other programs and includes, you can display them in the Repository Browser.
3. Now create a Function Module.
4. Enter the function's name in the field Function module.
5. Choose Create.
6. In the Enter function group dialog box, enter the function group to which you want to assign the function module.
7. In The Attributes Tab select Remote Enabled Module (since you want a RFC function module ).
8. Give the Import and Export parameters and exceptions(if any).
9. Write the functioning part of the fuction module in the Source code tab.
10. Save and Activate your function Module.
Now go ahead and use your function module where ever you want.
Hope it helps.
Reward if helpful.

Using RFC Function Module to send data to NON SAP Application

Hi friends,
Please guide me how can I send data from SAP -> Dotnet Applcation using Dotnet Connector through RFC function module from SAP side. In my scenerio, I Run Z transaction to executte RFC function module which create some data to pass to dotnet connector.
Regards,
Rajesh Kumar

Hi,
You can make use of Dotnet connector to read the content of SAP RFC .. (eaiest of all)
The RFC can be executed using connector , and can read the data simultaneously.. u need to code in dotnet for this..
else create a webservice and read it from dot net ..

How to debug a RFC function module remotely from another R/3 system?

Hi experts,
   I have RFC function module in one R/3 system. I am calling this from another R/3 system that is cross apps (Xapps).
   This function module is Synchronous.
Is it possible to debug this function module from cross apps?
Can somebody give me the steps?
Thanks & Regards
Gopal

Hi Shree,
   Can you explain it bit more?
   Do I have to call the function module with "IN BACKGROUND TASK"?
   Or is it that I have to just put external breakpoint in the function module?
   Please help
Thanks

Is it possible to call custom designed RFC function module, apart from BAPI

Hi Friends,
1. Is it possible to call custom designed RFC function module, apart from BAPI.
2. Why we call it Adaptive RFC layer, Since every time the JCO layer updated with SAP, Why cant be dynamic.
Thanx for Ur time.
Cheers,
Sam

Also check <a href="http://help.sap.com/saphelp_nw04/helpdata/en/41/38bc8f813719488ddc9d9b21251ec3/frameset.htm">here</a> for more information on aRFC. Here you can find why it is called adaptive.

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.

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.

Backgroung job failing becuase RFC function module is running in Dialog

Hi,
I have a program which is calling a RFC function module. I am running this program in background as a job. Now this function module which is in other system is running in Dialog and giving a time out error and the job is failing becuase of that.
I tried call fucntion 'test' in background task
destination 'XVZ'
tables
test = 'test'.
But this is not working, i can still see this function module running in Dialog in SM50. Any suggestion?
Thanks,
Shweta

Hi !
RFC-Called function-modules are running in a dialog workprocess of the
target system (they could not run in a batch proecess !!).
That means the do have the same "Timeout" limitations than any other
Dialog-Process.
What you can do:
- The Dialog "Timeout" could ce increased by your SAP-BASIS
- If they could not - you should "shorten" the LUWs in the target-funktion.
...means - put a COMMIT WORK an any point the work is done.
After a COMMIT WORK the "Timeout" Counter beginns at 0 !
Hope that helped....
Reward points would be nice...

Problem with RFC function module from R/3 to CRM

Hi, i have a RFC function module created in R/3, this is the code:
function Z_CRM_PRODUCTO_INTERLOCUTOR.
""Interfase local
*" IMPORTING
*"     VALUE(GV_VKORG) TYPE VKORG
*"     VALUE(GV_VTWEG) TYPE VTWEG
*"     VALUE(GV_MATNR) TYPE MATNR
*"     VALUE(GV_KUNNR) TYPE KUNNR_V
*" EXPORTING
*"     VALUE(GV_KDMAT) TYPE MATNR_KU
*"     VALUE(GV_POSTX) TYPE KDPTX
*" EXCEPTIONS
*"      NOT_FOUND
UNPACK GV_MATNR TO GV_MATNR.
UNPACK GV_KUNNR TO GV_KUNNR.
select single KDMAT POSTX
          into (GV_KDMAT, GV_POSTX) from KNMT
          where   VKORG = GV_VKORG
                  and VTWEG = GV_VTWEG
                  and KUNNR = GV_KUNNR
                  and MATNR = GV_MATNR.
IF sy-subrc <> 0.
    RAISE NOT_FOUND.
ENDIF.
endfunction.
When i call this function from CRM, i do it like this:
CALL FUNCTION 'Z_CRM_PRODUCTO_INTERLOCUTOR'
DESTINATION LV_RFCDEST
EXPORTING
    GV_VKORG = lv_vkorg
    GV_VTWEG = ORGMAN_H-DIS_CHANNEL
    GV_MATNR = ORDERADM_I_WRK-ORDERED_PROD
    GV_KUNNR = WA_DATOS_PER-N_PAGADOR
IMPORTING
    GV_POSTX = IT_POS_LINE-DESCRIPCION
    GV_KDMAT = IT_POS_LINE-material
EXCEPTIONS
    not_found = 1.
where:
it_pos_line-descripcion type string
it_pos_line-material type string.
Well, my problem is that when debugging, in R/3 the 2 return values have the correct value, but when they are passed to CRM they have only one position.
As i've been told, it was working ok, but it's being wrong since we made a ¿conversion to unicode?. Maybe I should change the type of return ???
Thanks in advance !!!

Hello Maria,
Make sure you define your parameters in CRM exactly the same way as in R3, do not use type string here.
So:
it_pos_line-descripcion type C char 40,
it_pos_line-material type C length 35.
Kind regards,
John.

Debugging RFC function module from ECC to CRM

Hi All,
My requirement is to debug an RFC function module present in CRM(7.0) system from ECC(6.0) system. A report program in ECC will call CRM custom FM. I found many posts in SDN with the same issue and tried to implement suggestions provided there. But I couldn't succeed. The approach I followed is:
I logged in to ECC report program and kept an external breakpoint just before the function module call.
I logged in to CRM system, opened the function module and kept an external breakpoint there.
In both the systems I provided the dialogue userid( id through which I log in to SAPGUI) in the system->settings->debugging option.
In CRM I activated the external break point in transaction SRDEBUG.
Now when I execute the report program in ECC, control stops at the breakpoint. If I press F5 at the function call, control is not going to the external break point set in the CRM FM. I am getting output of FM directly.
I tried with different settings like turning on the check box for IP matching and session breakpoint active immediate, switching to classic debugger etc. I also tried to provide the RFC user id instead of dialogue user but system throws exception saying only dialogue userids are allowed. I found that by inserting an infinite loop statement, control goes inside the RFC CRM FM but I prefer not to change the code.
Please let me know if I missed anything.
Thanks and Regards,
Naren

Hi,
Debug RFC calls
When an RFC function module is called it is usually not possible to debug the call, using the below techniques we can achieve the same. For this example we are calling an RFC enabled FM in ECC system from CRM system.
Scenario 1: Calling a custom RFC FM
STEP 1: Add an infinite loop in the remote custom Function Module (adding a u201CDO. ENDDO.u201D statement at the start of the FM would be enough).
STEP 2: Execute your program in the CRM system. The execution stops at the RFC call, because of the infinite loop.
STEP 3: Now login to the ECC system and go to transaction SM51 select the process which is executing the RFC and navigate to the menu: u201CProgram/Session->Program->Debuggingu201D this triggers the debugger session in a separate window.
Scenario 2: Calling a Standard RFC FM
When we are debugging a standard program we cannot add the infinite loop, hence we cannot go to SM51 and debug the work process. The RFC destination for the ECC system has a User specified, the RFC function module gets executed using this users credentials. Usually the basis team set up the RFC user as non Dialog user, this does not allow debugging. Contact your Basis team and get this changed to a dialog user enabling you to debug RFC function calls via the normal debugger.
Note: User name configured in the RFC destination (transaction SM59)
Note: User type for the RFC User (transaction SU01D)
Hope this will be helpful..

Unknown error calling a RFC Function Module in BODI

Hi all,
I am having an issue identifying the error that my batch job in BODI is giving with regards to a RFC function module call in my query. The value returned by the standard parameter 'AL_RFC_RETCODE' are square characters ( ).
At the completion of the job, the error message 'RFC CallReceive error <Function ZCT_INDSLS_SLS_TRN_INSERT: Invalid request.. Invalid request.>.' is being output.
Correct me if I'm wrong but the parameter 'AL_RFC_RETCODE' should return standard values as per the techical manual provided to undertand any errors that might occur during a RFC FM call.
Can anyone help me on this?
Best regards,
Andrew Wong

Hi Senthil,
I think you answered your query in your question itself
The user ID and password need to be maintained in RFC destination in SM59.
Go to SM59 and then click on test connection..if it does not ask for ID and passwoed that means correct ID and password is maintained in SM59 otherwise maintain it.

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

Hi Senthil,
