RFC function module exporting

Hi..
when I am trying to export some paramters and tables in RFC function module, i m getting error as well as a warning message stating performance will reduce.
So please help me to solve the issue.
Thanks
Vimalraj

You are getting this message because you are exporting tables 'by value'. Since this will cause the complete data in that internal table to be copied into a new memory area this might impact the performance of that function in case the table has a lot of data in it.
However - for an RFC you can only define parameters to be called by value, hence this is not an error in your case. It just lets you know that the performance will suffer when you have lots of data in your internal table compared to a function that would pass the data by reference - but you don't have that option for an RFC anyway.
Hope that helps,
Michael

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.

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.

Standard Component in CRM that will call RFC Function Module

HI all,
Is there any Standard Component in CRM that will call RFC Function Module from ECC and that called RFC FM should Fetch the data from ECC.

You can call RFC from different places, like programs, function modules, web dynpros, classes...
So you just have to have appropriate RFC on ERP side and call it from CRM side. To call it you use the following statement...
      CALL FUNCTION 'YOUR RFC FUNCTION'
        DESTINATION i_dest "name of server
        EXPORTING
          your export parameters
        IMPORTING
          your import parameters

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.
with regards,
Suresh Aluri.

RFC function module with call transaction and Import memory ID

Hi,
I am calling RFC function module from R/3 which exists in BW.
In BW stand alone function module works fine.
When I am Calling from R/3 it is not working,
Can you tell me is it because of the below code, And suggest if any corrections required.
I am calling the call transaction and using EXPORT memory iD inside the program
and IMPORT in after that.
And populating RFC table's table " p_i_tcode_user" finally.
set parameter id 'TCD' field p_tcode.
call transaction 'Z_BW_RSUSR002' AND SKIP FIRST SCREEN.
ENDIF.
get the final user data from submitted program
import gt_users_complete from memory id tcode_userid.
LOOP AT gt_users_complete.
      lwa_tcode_user-tcode = p_tcode.
      lwa_tcode_user-uname = gt_users_complete-Bname.

i need a RFC with only Request message and Response message is not required.
please help me, how to create a RFC function module with out Response message, and it should contain only Request message.
i have created RFC in this way:
RFC doesn't contain neither import nor export parameters. and i have defined one table in TABLE tab which refers to a ztable created already.
when i imported RFC into XI i came to know that RFC has both Request and Response messages, but i don't need Response message.
Thanks in advance..help would be appreciated

if sy-subrc = 0.
commit work.
else.
rollback work.
im not using neither import nor export parameters..but using only tables parameters. but when imported in XI im getting same table structure in both request an response.
please suggest what changes required in above code to invoke my ZRFC in async way.
you will not get any response in XI- what chages required in my code to dnt get .reponse in XI.

What are the steps we have to follow to develop RFC function module

hi
what are the steps we have to follow to develop RFC function module

I will tell you simple example within r/3 systems..
source system - A (SAP R/3 )
Destination System B (SAP R/3).
First create RFC Destination in SM59 - in A System.
Createing RFC Destination - GOTO SM59 Transaction and click R/3 System .
it will go second screen and give ur RFC Name ,IP Address and log on details.
click on test concetion and remote logon.
now create RFC Function module in B System.
goto se37 - create fm with starting with Z* or Y*.
maintain all data like
attribute should be remote enabled
importing is v_matnr
exporting is v_maktx.
write the simple code - select single maktx from makt into v_maktx
where matnr = v_matnr.
Call this fm in report program in se38 in B sytem and copy the FM.
paste this code A System
use ur logic and destination 'RFC Name'.
Reward Points if it is helpful
Thanks

Hi
Instead Of giving write statement inside a function module
write these statement where this rfc is called.
if rfc connection is established ,then
number will be printed.
otherwise not.

How to create RFC function module and how to call this function module

Hi,
i want to know step for creating RFC function module and then How to use this function module from some other sap system.
Thnaks,
jigar

Jigar,
To implement a remote function module in ABAP, perform the following steps:
Register the module as remotely callable in the RFC server system.
In the function module Administration screen (transaction code SE37), set the field Can be called via REMOTE CALL. Registering a module as remote causes an RFC stub to be generated for it.
Write the code for the function module.
Create the destinations.....................
Displaying, Maintaining and Testing Destinations
To display, create or modify destinations, choose Tools ® Administration ® Administration ® Network ® RFC destinations or enter transaction code SM59.
Remote Destinations are stored in table RFCDES. The RFCDES table describes logical destinations for remote function calls.
It is not possible to maintain the RFCDES table directly.
You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® AcceleratedSAP ® Customizing ® Execute Project ® SAP Reference IMG.
In the Implementation Guide, expand the following hierarchy structure:
Basis
Application Link Enabling (ALE)
Sending and Receiving Systems
Systems in Network
Define Target Systems for RFC Calls
Displaying Destinations
The initial screen for this transaction displays a tree:
Different connection types (i.e. partner systems or programs) are possible. For further information, see Types of Destinations.
To display all information for a given destination, double-click it, or place the cursor on it and press F2 .
To search for a destination, press the Find button and specify your selection. You get a list of all entries matching your selection. Place the cursor on the one you want, and press F2 or simply double-click the destination. All information for the given entry appears.
Creating Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
All available connection types are explained in Types of Destinations.
To create a new RFC destination, press the Create button. A new screen is displayed with empty fields for you to fill in.
If you want to create a new destination
As you create a remote destination, you can specify a particular application server or a group of servers for a balanced distribution of system load.
For details of the destination parameters, see Entering Destination Parameters.
Changing Existing Destinations
On the destinations overview screen (transaction code SM59), the connection types and all existing destinations are displayed in a tree structure.
You can display all information for a given destination by double-clicking it or pressing F2 on it.
To change an existing destination, double-click it, or place the cursor on it and press the Change button.
For details of the destination parameters, see Entering Destination Parameters.
Testing Destinations
To test a destination, choose the appropriate function from the Test menu.
Connection (also available via the Test connection pushbutton)
Authorization (checks logon data)
Local network (provides a list of application servers)
You can use the CALL FUNCTION statement to call remote functions, just as you would call local function modules. However, you must include an additional DESTINATION clause to define where the function should run:
CALL FUNCTION RemoteFunction
DESTINATION Dest
EXPORTING
f1 =...
f2 =...
IMPORTING
f3 =...
TABLES
t1 =...
EXCEPTIONS......
The field Dest can be either a literal or a variable: its value is a logical destination (for example, "hw1071_53") known to the local SAP System. Logical destinations are defined in the RFCDES table (or the TRFCD table in R/2 Systems) via transaction sm59 or the following menu path: Tools ® Administration, Administration ® Network ® RFC destinations. You can also access logical destinations via the Implementation Guide (IMG) by choosing Tools ® Customizing ® Enterprise IMG. In the Implementation Guide, you can then choose Cross-application components ® ALE ® Communication ® Define RFC destination.
The remote function call concept, for example, allows you to access a function module in an R/2 System from an ABAP program in an R/3 System. If you want to read a customer record from your R/2 Systems database, create a remotely callable function module in the R/2 environment which retrieves customer records. Call this function from your R/3 System using a remote function call and listing the destination for the target R/2 System:
Pls. reward if useful

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

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.
