Calling a function module on another server

Dear all,
I have a function module on a test server which accesses a database table on it. I need to call that function module from a development server. Both servers are AS ABAP. I believe I need RFC, but how do I specify the test server address from the development server function call?
Thanks for your help,
Philon

You need to call the Function module as a RFC FM.
The function module needs to be set as such.
In its atributes, it needs to be Remote-enabled function module.
To call it, proceed as follows:
CALL FUNCTION <FUNCTION MODULE> ON <DESTINATION>.
<DESTINATION> needs to be a predefined RFC destination. (See transaction SM59)
CALL FUNCTION func DESTINATION dest parameter_list.
Effect
Synchronous call of a remote-enabled function module specified in func using the RFC interface. Use addition DESTINATION to specify the destination in dest. For func and dest, character-type data objects are expected. After terminating the remotely called function, the calling program is continued after CALL FUNCTION.
Note
If the content of dest is equal to the constant space, then the addition DESTINATION is ignored and a normal call CALL FUNCTION func is executed.

Call a function module inside of another function module

Has anyone ever called a function module inside of a remote enabled function module? Maybe this needs to be accomplished inside of an include. Just wondering.
Thanks!

Hi
No u can't do it because the RE_LAST_DAY_OF_MONTH is not remote function module.
If you need to call it u should insert it in a RFC, so u should create in R/3 a new RFC calling both fms: RE_LAST_DAY_OF_MONTH and the remote one.
And so call this new rfc instead of the other one.

Thanks so much.

Have you checked the user that is used to connect from J2EE back to ABAP?
I had a similar problem, went into the Visual Administrator and found the incorrect password (or possibly outdated password) was being used to communicate back to ABAP, and updating that sorted out my problem.
Hope this helps.

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

How to call a function module in VC

Hi,
I want to call a function module for an addition formula which shall calculate and infer the value.
eg. quantities of 5 different characteristics (of numeric data) is to be summed up and inferred against the 6th characteristic.
I want to know the detailed process to create a Variant Function and use it in a dependency.
Request to please advise the steps, type of dependency and its code.
Regards,
Rajesh Mohapatra

Dear Rajesh,
I also wanted to learn how to do that, your post motivated me to use a bit of freetime and investigate on the subject. I finally made my function work, so here are the tips.
The example is very simple, just a variant function with two inputs and which multiplies inside the input values and transfer that result to the output ( 3 x 4 => 12 ).
Deducting how to add five values or any other logic would be easier starting from there.
STEP 1: Create Variant Class for the product. I imagine you already have that. In my case its name is ZVC_CLASS, you have already a material assigned to the class, a configuration profile, etc....
STEP 2: Create Three Characteristics Z_NUM_CH_1,Z_NUM_CH_2,Z_NUM_CH_3 the three of numeric type
STEP 3: Assign characteristics from step 2 into class ZVC_CLASS
STEP 4: Create the function module with the code given below. I put the name ZVC_FUN_TEST
FUNCTION ZVC_FUN_TEST.

For this I create a characteristic in CT04 Z_CALCULATE type CHAR 1 with possible values Y or N. For the value Y y add the procedure ZVC_PROC_TEST so that formula only activates on Y.
STEP 8: Add characteristic Z_CALCULATE to class ZVC_CLASS

How to call Z-Function module from BAPI_IDOC_INPUT1.

Hi All,
Process code is :BAPI and standard function module is BAPI_IDOC_INPUT1.
I am coding all the logic for the INBOUND IDOC in the Z-Function module ZIDOC_INPUT_ZGOODSMOVEMENTOIL.
My requirement is:
Process code fires the inbound function module BAPI_IDOC_INPUT1, this in turn call the function module ZIDOC_INPUT_ZGOODSMOVEMENTOIL.
How can i call ZIDOC_INPUT_ZGOODSMOVEMENTOIL from BAPI_IDOC_INPUT1 to process the idoc.
Thanks in Advance.
Regards,
Umesh

Hi Krush,
Thanks for your reply,
Now i can trigger the idoc.
I have one more problem that if i want to add another z-segment to the attached idoc type its not allowing me its saying that it is already generated and cannot be changed.
if i am generating the BDBG transaction its not asking for specific segment and it automatically takes the segment and generates the function module.
How i can add an additinal z-segment to the idoc type and it generate through BDBG transaction to include in inbound function module?
Thanks in Advance.
Regards,
Umesh

Calling generic function modules

Hi all!
As .NET connector doesn't support the call of function modules or bapis that are not known at design time, I found another tool on the web (see www.erpconnect.net).
Does anyone have any experience with this library? My first test programs work very well.
Kind Regards,
Markus

Have you looked at the SAP Connector for Microsoft .NET (NCo, also known as "SAP .NET Connector")? This is made exactly for that and comes with documentation and samples. SAP customers can download it from http://service.sap.com/connectors .

Is it possible to call Normal function Module from WD4A , Not RFCs

Is it possible to call Normal function Module(FM) from WebDynPro for ABAP , Not RFCs

There is no difference, unless you are specifically calling the RFC to connect to another system. If so, then you need to add the DESTINATION keyword to the function call and specify the destination name. This name must be defined in SM59. But, if you are not going to another system, you can call the RFC the same way you call the regular function module.

V Urgent : Debugging an RFC function Module in another R/3 system

Hi All
I have a function module in a R/3 system ( say WB1 ) and i am calling it from another R/3 system (say WD1) . Both have their RFC destinations set up as trusted system mutually . However when i try to debug that FM while in WD1 ( which basically exists only in WB1) i am not able to get inside that FM . Are there some settings that we need to do to allow us to debug function module in another R/3 system ? .
Yes ,we cant do this debugging if RFC function module is in a non SAP system but am sure it can be done atleast for R/3 to R/3 .
Any pointers to this as to what setting needs to done ?
Does some system parameter needs to be set in RSPARAM program for debugging RFC?
Please help
Regards
Shovit

Hi
Can you do a remote logon through the SM59 connection (the trusted one)?
If so, then the only thing preventing you would be debugging autorization.
If not, make sure you have trusted system logon auth (not part of SAP_ALL!).

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:

What is the exact syntax for calling remote function module.

Hi to all
1.....what is the exact syntax for calling remote function module.?
Thanks and regards,
k.swaminath reddy

hi
good
Lets do simple example where you will first create a RFC in one server (say A) and create normal program in othere server (say B). Finally you will call the RFC in A from B.
Do the following steps for creating RFC in server A.
1. log on to server A
2. go to se37
3. Edit -> function groups-> create function group and give the function group name (say ZGRP).
4. create a FM ( say Z_TEST_RFC) in se37 providing the function group which is created just now.
5. go to attribute tab -> choose remote-enabled module from processing type.
so that your FM will become RFC.
6. provide the import parameter in import tab.
we will provide only two import parameters.
- parameter name : P_NUM1, typing: TYPE, associated type : I & check the pass value (all the parameters of RFC must pass by value).
- parameter name : P_NUM2, typing: TYPE, associated type : I & check the pass value
7. provide the export parameter in export tab.
parameter name : P_SUM, typing: TYPE, associated type : I & check the pass value
8. write the given simple code in source code tab.
FUNCTION Z_TEST_RFC.
P_TOT = P_NUM1 + P_NUM2.
ENDFUNCTION.
Do the following steps for creating ABAP program which will call the RFC in server B.
1. se38 - > creat a program.
2. write the given simple code.
data tot type i.
call function 'Z_TEST_RFC' destination 'XXXXXX'
exporting
p_num1 = 10
p_num2 = 15
importing
p_tot = tot.
write tot.
please note that XXXXXX is RFC connection which is avialable in sm59 transaction in server A.
-go to sm59 - > abap connection (list of RFC connection configurations are avialable). choose server B connection and replace it of XXXXXX in the code.
finally you can execute the normal abap program that will call the RFC and display the result.
reward point if helpful.
thanks

CNTL_ERROR while calling a function module from Java webdynpro

I am calling a RFC function module from javawebdynpro app
which inturn calls a function module performing BDC on CAPP transaction. When I run this from SE37 of the same system or a different system everything works fine. But when called from Java webdynpro app, it raises a CNTL_ERROR exception and creates a short dump.
Any help on this is highly appreciated

Good catch, BI Learner. This was exactly it: when assigning the values from SOURCEFIELDS directly to the import/export parameters, you have to make sure that the types are EXACTLY the same, otherwise it will not work (the routine stops with an error when calling the FM, but there is no dump).
Therefore, to solve my problem, I created the declarations precisely as expected by the FM and assigned the values to these fields:

      SOURCEVAL TYPE /BIC/OIINVQTY,
      SOURCEUOM TYPE /BIC/OIUSUOM,
      USITM TYPE /BIC/OIUSITM,
      TARGETUOM TYPE /BIC/OIUSUOM,
      CONVERTED_COST TYPE /BIC/OIINVQTY.
DATA PRODUCTION_UOM TYPE /BIC/OIUSUOM.
" get the Production UOM
    SELECT SINGLE I~/BIC/USPRDUOM
      FROM /BIC/PUSITM AS I
      INTO PRODUCTION_UOM
      WHERE I~/BIC/USITM = SOURCE_FIELDS-/BIC/USITM AND I~OBJVERS = 'A'.
    IF ( SY-SUBRC = 4 ). " no records found
      "RAISE PARTNO_NOT_FOUND.
      RAISE EXCEPTION TYPE CX_RSROUT_SKIP_RECORD.
    ENDIF.
" load the parameters
    SOURCEVAL = SOURCE_FIELDS-/BIC/USFRZMFC.
    SOURCEUOM = SOURCE_FIELDS-BASE_UOM.
    USITM = SOURCE_FIELDS-/BIC/USITM.
" then you can call the FM
    CALL FUNCTION 'Z_CA_CONVERT_US_COST'
      EXPORTING
        PSOURCEVAL                = SOURCEVAL
        PSOURCEUOM                = SOURCEUOM
        PUSITM                    = USITM
        PTARGETUOM                = PRODUCTION_UOM
      IMPORTING
        PTARGETVAL                = CONVERTED_COST

Can we call a function module in ADHOC query

Hi
Can we call a function module in ADHOC query if yes how.
Also we ned to know how to call a function module in SAP query.
An early responce is appreciated.
Thanks and best regards
Rajeev

Okay as far as I understand your aim is:
To fill a field in the output list with a value that is based on the current line information and calculated by a function module
So go to SQ02 and create an additional field in the InfoSet.
You can refer in the coding to the technical names you can see in the left tree window like P0000-PERNR.
More information is avaiable in the Help part look for additional field in SQ02.
