Ways to call a ABAP Function module or ABAP Program from WAD

Hi,
Is there any way to execute an ABAP function module or program from the WAD?
Thanks

what you could do is create a bsp application which receives workbook id as url parameter.
from WAD create a link to this BSP page and pass the wbook id in the url.
within the BSP you can then read the excel as binary string like below
select * from rsrwbstore into table wb_tab
where workbookid = wbid.
you can then set wb_tab-clustd as the response of the page with mime type to 'application/vnd.ms-excel'. which will open as excel

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,
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.

Debugging of ABAP Function Module through ISA Application CRM B2C 4.0

Hi Experts
There is way to Debug ABAP FM through ISA CRM b2c Application by Modifying some XML Files as per Extn Guide.
I tried modifying the <APPLICATION_HOME>\WEB-INF\xcm\customer\modification\modification-config.xml After that I restarted the Application .
But it is not Breaking for Both Statefull & Stateless FM after running my Application.
With Some Help i found that if we try it on Remote System ( Means SAP GUI has to in Same System where CRM is Installed ???????????). but that is not Advisable Right !!!.
So if i am able to Debug ABAP Function Module through ISA Application from any Other remote System.
I think it will be very Useful.
Thanks & Regards
Ravi Sah

Ravi
It is other way around !!!
You should have SAP GUI installed on the machine in which you start(access) your B2C Application. This enables for ABAP Debugging.
We have tried this and works fine for us !!!
Thanks

BW/ABAP- Function module is called infinitely by Datasource Extractor.

Hi All,
A quick ABAP question related to Function Modules and BW data source extractors.
Ive written a function module to select data from a database and simply output the data as a table. I then created a text Datasource using transaction rso2 and set it to Extraction by Function Module.
When I test this using transaction rsa6, I can manipulate the number of calls to my function module using the Display Extra Calls field.
However, when I test this using transaction rsa1, my function module seems to be called infinite times. So, the number of records being retrieved is increasing exponentially and finally ends with a dump.
My question: Do I need to include something in my code such that the Function Module by itself will only be called once?
Or is there some configuration for the Datasource that will limit my function module call to once only.
Tried so far
Introducing a static variable in the function module that exits as soon as the value is greater than 1.
o Is there another way out?
Regards,
Preethi.

You need to raise the EXEPTION NO_MORE_DATA afte the last record is populated in the output table. Otherwise the program goes into an infinite loop.
* From now on records get fetched from the database or gets read from the internal table
    FETCH NEXT CURSOR v_cursor
               APPENDING CORRESPONDING FIELDS
               OF TABLE <internal table>
               PACKAGE SIZE i_s_if-maxsize.
    IF sy-subrc <> 0.
      CLOSE CURSOR v_cursor.
      RAISE no_more_data.
    ENDIF.
* Populate the Output Data Structure into table E_T_DATA and you need to raise the EXEPTION NO_MORE_DATA and close the cursor to avoid any memory leaks

Calling ABAP Function Module in BODS, but not RFC_enabled

Hello Experts
We have an ECC ABAP Function Module takes 5 input parameters and returns Division Name for an Employee and Employee PERNR is one of the input parameters for the Function Module.
I tried adding a function call in the target schema of Query Transform and the output parm passes out as an Output column. But getting an error that ABAP FM is not RFC_enabled. I checked attributes, and it is not RFC_enabled.
So is there way to invoke this FM as part of BODS ABAP Dataflow?. Becuase the code executes on ECC, it does not need to be RFC enabled, I believe. But on the Query Transform, the option "New Function Call" isn't enabled or it is greyed out, I can't select it.
What is the solution to invoke this ABAP FM with enabling RFC on it ?
Please provide me your inputs.
thank you

Hi,
Create a custom wrapper FM which is Remote enabled & call the FM DD_DOMA_GET inside your custom Remote FM. Changing the std. FM would be a core code mod. hence above approach would be safe.
Thanks,
Best regards,
Prashant

Call ABAP function module from script?

Hi,
I have an ABAP function module, which works fine when I call it in a transformation.
Since I don't need to execute this function for each record but rather for each file I process, I would like to move the call from the DataFlow to a script in the WorkFlow. When I click on the 'functions' button the ABAP FM is available in my SAP Datastore, so I drag and drop it into my script. I also make sure to populate all required variables.
There are no error messages or warning when I check my job definition.
When I execute it, I get the following RFC error:
Function call <xxx ( abcd ) > failed, due to error <150413>: <RFC CallReceive exception <FUNCTION_NOT_FOUND>.>.
Is it just not possible to call an RFC enabled function module in SAP from a script or am I doing something wrong here?
Thanks,
Jan.

Could you please let me know how I can call an abap function module from a transformation? (from abap xslt program). I know how we can call methods of a class from the transformations, but no idea how we can call function modules. Any suggestions or a sample code snippet towards this will be very useful for me.
Thanks,
Shashi.

Calling an ABAP function module

Hi friends,
I am developing an application in EP6 SP2 using JSPDynPage from which, want to call an ABAP function module that returns table and show the values from this table in this application.
I went thru various blogs and APIs. I am confused between SAP JCO, JCO client service and connector framework. Do u have any documentation on how to connect to R3 systems and call a function module, retrieve results etc.
Regards,
Nilz

JCo is the point to start. This gives you low level access to all rfc functions. Everything else (accept BSP and Web dynpro) are just layers of encapsulation around the low level JCo function.
The steps are always like this:
call the sap system for rfc login
prepare data areas and call in java
call the rfc in the R/3 system
handle exceptions
logoff and free ressource
continue with data obtained in R/3
There is a lot of material around jco. One book that is fairly ok is :
SAP Interface Programming
A comprehensive reference for RFC, BAPI, and JCo programming

Call an ABAP Function module on click of Button in BSP page

Hello ,
i would like to run a ABAP function module on click of a button in BSP page.
or in other words i want a Funtion module ex: 'test1' to run after clicking this button ex: 'button1'
and how to pass the values for a function module after clicking the button.
i an new to bsp application .
Can anyone help me on this .

Hi Shalaxy,
Triggering a URL to WDJ:
I suppose the URL of WDJ app. is also a portal URL. I assume that from a BSP application inside portal you need to trigger the WDJ url.
But the catch is that you cannot hotcode this URL, since it varies for a development, quality and production systems(diff. portal environments).
To solve this issue, ABAP provides a system variable named sy-sysid, which says want system your ABAP system is, normally a development R/3 system will be associated to development portal system and quality R/3 to quality portal ans so forth.
So you could have a internal table/db table/ variable for dev, quality or prod portal urls and from the bsp on button click based on the value in the sy-sysid you can trigger the url accordingly.
Creating a URL in WDJ
The above is about triggering a WDJ from BSP. But if you dynamically want to create a link in WDJ on a button click, then apparently you could not do that from BSP, since the applications are different. All you could do is to pass some URL parameters to WDJ application from BSP app. Then based on the URL parameters the WDJ application has to dynamically create a link and add it to its application.
Hope it helps.

Multiple calls of same function module do NOT initialize variables ?

Hi all,
..so its my fist post here, this is a bit strange problem for me and maybe someone knows whats happening.
So I have in SAP Solution Manager a function module 'Z', which calls a standard SAP class CL_SPROJECT_SOLAR_BASE_REPORT, which in turn calls the standard function module 'SPROJECT_GET_ADMIMP_SCREEN_BP'.
During development, things worked fine, but now I run my Z-Program for more than one instance and even I do all FREE for the Class, apperently the function module SPROJECT_GET_ADMIMP_SCREEN_BP, which is called by the class CL_SPROJECT_SOLAR_BASE_REPORT, does not get it's variables from the global data of the function pool re-initialized, when it is called for the second, 3rd, ... time.
This is a bit strane behavior for me, I would have expected that variables in a function module (or even in the global data of that function pool) get re-initialized each time that function module is called ?
Actually, this is the only function in that function pool.
Well, if not, does anyone has an idea how I can get the variables of this module pool re-initialized between the calls ? More concrete, the global data of function pool SAPLSPROJECT_SOLAR_ADMEVAL_BP define:
DATA: g_v_with_var TYPE char1.
In the function module line 36 (no reference to g_v_with_var, no module call, no changes to g_v_with_var before the IF-statement at all) it is querying:
IF g_v_with_var IS INITIAL.
So this is my problem, the second time I am calling the class (which is 'free'ed and re-created between the calls) which calls this function module the 'g_v_with_var' is not initial and there seems to be no way to have it set to initial again ?
So even thought this is in SolMan, I think the question & problem is a ABAP technical one ?
Any thoughts, help or support would be very much appreciated,
thank so much,
Frank

Hi Mae,
..thanks a lot for your fast reply, unfortunately there is only one function and no functions or forms at all for initializing. The variable I am fighting with is g_v_with_var and that is referenced only 4 times in the whole function pool:
Global Data:   101 DATA: g_v_with_var TYPE char1.
Function Module SPROJECT_GET_ADMIMP_SCREEN_BP (which is the only function module):
    36   IF g_v_with_var IS INITIAL.
   127       g_v_with_var = airep_true.
   193         CLEAR g_v_with_var.
If in line 36 g_v_with_var is 'X', which it is always after the first call, the function will exit with an exception, so line 193 to clear it will actually never be executed...and it is not cleared the next time the function module is called, so you never get back to have the function run...
All the best,
Frank

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.
Edited by: Julius Bussche on Jan 22, 2009 7:19 PM
Please read the forum rules about u r g e n t ...

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.
Cheers,
Julius

Issue in creating web service for a ABAP Function Module

Hi,
now i'm learning how to create web service for a ABAP Function Module. I used the following steps.
1. select the Function Module, named "zws_test".
2. in the context menu, select "create->proxy object". so we enter into wizard.
3. in the wizard, press the radio button "Service Provider".
4. in the next page, press the radio button "Existing ABAP Objects(Inside Out)".
5. In the next page, Enter the "zws_test_prvider" as Service Definition and select "Function Module" as Endpoint Type.
6. in the next page, enter "zws_test" as Function Module and mark the "Mapping der Namen" button
7. in the next page,select "PRF_DT_IF_SEC_LOW" as Profile and mark "Deploy Service".
8. Save in the local package.
9. then it will pop up a window with title "WSDL Source". i selected "URL/HTTP Destination" and press "OK".
10.in the next page, i enter the URL as "http://hostname:portnumber/", and press "OK".
11. then it will pop up a window with title "Display logs". A record with error message "HTTP error(return code 404, message "Not found")" appears.
12. i press "ok" and a service provider with name "zws_test_prvider" appears in my local package.
13. i use "zws_test_prvider"'s URL to create a service consumer "ZCO_WS_TEST_CONSUMER" and logic portal "LP1".
14. But when i test my service consumer "ZCO_WS_TEST_CONSUMER", it will throw an exception "cx_ai_system_fault" with errortext "SOAP:14 Unexpected element -el=definitions ns=http://schemas.xmlsoap.org/wsdl/".
15. I use t-code SM59 to test connection and get the following info.
      Status HTTP Response     200
      Status Text                      OK
      Duration Test Call             328 ms.
who can give me the reasons about item 11 and 14, and explain me how to create service provider and service consumer for a Function Module.
Thanks in advance

Crystal Reports for VS2010 using a custom SAP ABAP function module data source

I recently worked with Crystal Reports 2011 and was able to connect and retrieve data from our R/3 system via an ABAP function module. While researching other features, I found this version that can be installed into Visual Studio 2010. The parameters are not very user friendly in Crystal Reports so I was hoping to create a custom dialog to collect my report parameters.
Does anyone know if I were to install Crystal Reports for Visual Studio 2010, would I be able to design a front-end selection screen in a Visual Basic form and then pass the input to through the Crystal Reports connection to my ABAP function module to retrieve the data filtered on the back-end by the selection screen parameters and return the results to be reported in the Crystal Reports output?
I am using Visual Studio 2010 Professional Visual Basic with the .NET Framework 4.0 on 32-bit Windows 7. I was able to connect to our R/3 system in Crystal Reports 2011, so if I were to install Crystal Reports for VS2010, would there be a similar way of connecting to SAP?
Any assistance or direction would be greatly appreciated.
Thanks,
Bryan

Hello Bryan
I don't know for sure, but I doubt this will work in CRVS2010. Only hope is that the utility available for download in this KBA will point you in the right direction.

Help on ABAP Function Module (Unit 1)

Hello ABAP Experts,
I need help with the below mentioned lesson plan. I donot have source code for The ABAP Function Module - BC401_GET_SEP_STRING. For the Source Code Solution in the Lesson Plan to work, I need the source code for the above mentioned function module.
The Lesson Plan with Solution is posted below:
Exercise 1
Unit: Data Types and Data Objects in Detail
Topic: Defining Data Types and Data Objects
Basic Statements
Processing Character Strings
At the conclusion of these exercises, you will be able to:
u2022     Define structure types locally in the program
u2022     Define elementary and complex data objects
u2022     Split strings
u2022     Use conversion rules
u2022     Display the contents of data objects in lists
In this exercise, you will use a template to create a program that receives a single data record from the database table SFLIGHT in form of a character string. The program will split the this character string into its components and display it formatted in a list.
Because the focus of this exercise is not on the transfer of data as a character string, we will use a function module that will provide us with the required database. This will simulate actual cases, such as data transfer from an external system.
Program: ZBC401_##_SPLIT_STRING
Template: SAPBC401_DTOT_SPLIT_STRING
Model solution: SAPBC401_DTOS_SPLIT_STRING
is your two-digit group number
1-1 Copy the program, SAPBC401_DTOT_SPLIT_STRING and give it the new name ZBC401_##_SPLIT_STRING.
1-2 Familiarize yourself with the main body of the program. Pay special attention to the content of the data object datastring after the function module call. Use the Debugger to do this, and/or display the character string in a list. (The function module itself is here seen as a black box. For this exercise, it is not necessary to understand its construction.)
1-3 To be able to split the character string into its components you must first remove the ## characters. Remove the two leading separators from the character string first. Then copy the initial part up to the closing separators to the auxiliary variable set_string. For this, set_string has to be defined appropriately.
1-4 Now use the separators to split the contents of the auxiliary variable set_string into the structure wa_flight_c. The latter is typed with the local program structure type st_flight_c. You still have to comment out the components of this structure type and assign them an appropriate type.
1-5 As a test, display the fields of the structure, wa_flight_c in a list.
1-6 In the list displayed in exercise 1-5, you should have observed that some of the fields were displayed without formatting u2013 for example, the PRICE field. Your next step is to change this.
To do this, convert the data you have extracted by copying it to data objects with suitable types. Also, not all components of wa_flight_c are to be displayed.
For this purpose, a structure wa_flight has already been defined. It is typed with the structure type st_flight. You must comment out the components of st_flight and find appropriate types for these components for the formatting. Then copy the identically-named components of the character-type structure wa_flight_c to the fields of the structure wa_flight.
Display the contents of the structure wa_flight in a list. Use the appropriate formatting options for the WRITE statement for the fldate and price components.

Web Services from ABAP function modules return values- leading zeros

I am using several web services from SAP CRM (5.0) that were created from Function modules ( I am assuming that that they are in ABAP).
I can call the web services fine and they work as expected, but I am seeing a lot of leading zeros in the return values of fields in tables from the Web service.
The ABAP ers are telling me that they cannot see the leading zeros.
So my question is where these are appended to the values in the whole process. When I execute the Function Module in SAP CRM from transaction SE37 I can see the leading zeros. So I think that this is something that has to be handled by the ABAP ers and not in the client consuming the web service.
Are the functions in SAP CRM that can remove leading zeros for fields in a table (that is an export parameter?)
Jawahar

Hello Jawahar
If you run your (RFC-enabled) function modules using the SAP-GUI (i.e. in dialog) then the GUI automatically replaces leading zero when the function module returns any data. However, calling the same function module remotely you will always see these leading zeros.
These so-called conversion exits are defined as attribute of domains in the ABAP dictionary. If the function module used for the WebService is a standard fm then you have little chances to get rid of the leading zero. Perhaps the WebService has some attribute to suppress conversion exits or activate them when retrieving the data.

Uwe

Where should i call the rfc function module? in xi or in r/3

where should i call the rfc function module?
for the synch scenario: file < -- > xi <---> rfc
i know the type of rfc is tcp/ip; but i'm not sure with the followings,
and with some trials i can not even see any message via rwb even all the setting
can be activated without errors.
where should i create the rfc destination? in r/3 or xi
where should i call the rfc via abap program? in r/3 or xi
i guess the calling program should belong to the different server with the rfc itself....
so confused....
Thanks for your reply!!
Jun

if i create the destination in xi point to r/3, then i call the rfc use the destination in r/3 right ?
The call doesnt use the destination in R3. XI has the RFC destination which is just used to connect to the R3 system
but where i need to create the fm via se37? in xi or r/3 ?
In R3
