CALLING FUNCTION MODULE

HI ALL,
How can we call a function module from a program? Do we need to copy the definition (i.e. importing ,exporting ...etc) in the calling program ?
especilly i want to know ,how to call BDC_OPEN_GROUP in a BDC program.

Hai Geetha
Just put the cursor at the start of the line where ever you want to insert the Function module
press 'Ctrl+F6'
give 'BDC_OPEN_GROUP' and press enter
then you will pass mandatory parameters
Thats it
Check this as bellow
form open_group.
call function 'BDC_OPEN_GROUP'
EXPORTING
   CLIENT                    = SY-MANDT
DEST                      = FILLER8
   GROUP                     = 'SRINU_PPP'
HOLDDATE                  = FILLER8
   KEEP                      = 'X'
   USER                      = sy-uname
RECORD                    = FILLER1
PROG                      = SY-CPROG
IMPORTING
QID                       =
EXCEPTIONS
   CLIENT_INVALID            = 1
   DESTINATION_INVALID       = 2
   GROUP_INVALID             = 3
   GROUP_IS_LOCKED           = 4
   HOLDDATE_INVALID          = 5
   INTERNAL_ERROR            = 6
   QUEUE_ERROR               = 7
   RUNNING                   = 8
   SYSTEM_LOCK_ERROR         = 9
   USER_INVALID              = 10
   OTHERS                    = 11
IF SY-SUBRC <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
endform.

Uncatchable exception: BSP calling Function Module

Hi all,
currently i'm facing a very weird problem. My application class calls function module
HR_INFOTYPE_OPERATION. Normally, in case of an error, the function module gives you back a return parameter. But if i call it from my BSP, the processing doesn't leave the function module. It directly throws an exception ERROR_MESSAGE_STATE instead of writing the message into parameter return.
If i call the function module with the same parameters from a report, it works fine and the error message is written to return parameter without throwing an exception.
What am i doing wrong? I don't want that exception and need to go on with filled parameter result.
Regards
Mark-André

Hi MA,
try using ERROR_MESSAGE in the exceptions list, like this.
CALL FUNCTION 'func_name'
     EXPORTING
          string            = text
          pos               = position
     IMPORTING
          string1           = text1
          string2           = text2

          string1_too_small = 1

What is the use of CALL FUNCTION MODULE - AT BACKGROUND TASK?

Hi experts,
I found Call functional module in background task will make the FM run at the next commit work as some people said. So I have some questions:
1 if we use COMMIT WORK commend, the pending FM will be called? If there are several FMs called at background task, what is the sequence of them? How many conditions will trigger the running of these FMs?
2 Where can I find the log of this pending FMs? In SAP library, it says there are 2 tables. But I checked these tables and can only find the FM name and user of it. And I can not understand content of these tables. It seems one is for the main information of FM, and the other is for the data of the FM, maybe the parameters.
3 If I call a FM in this way, Can I canncel it before the next commit work in some way?
Finally, thanks for reading and help.

HI,
When the COMMIT WORK statement is executed, the function modules registered for the current SAP-LUW are started in the order in which they were registered. ROLLBACK WORK deletes all previous registrations for the current SAP-LUW.
If the specified destination is not available when COMMIT WORK is executed, an executable program called RSARFCSE is started in background processing. By default, this tries to start the function modules registered for a SAP-LUW in their destination every 15 minutes and up to 30 times. These parameters can be changed in the transaction SM59. If the destination does not become available within the defined time, it is recorded in the database table ARFCSDATA as the entry "CPICERR". The entry in the database table ARFCSSTATE is deleted after a standard period of eight days

Third party system call function module/BAPI through RFC to update Z table

Dear Friends,
We have a third party system which directly inserts a Z table in SAP through its programming, which is an auditing issue.
We want the third party system should call function module/BAPI through RFC so that the Z table gets updated.
waiting for inputs..
Thanks,
Kumar

if third party system is capable of making Remote Function call, then writing a Function module & making it remote enable is not difficult task in ABAP.
You may have to prepare specifications first to decide if third party system is going to Read, insert, update, delete records from Zee table.

Why Service Call and why not call Function module Directly in WD ABAP

Hi,
I have created a Webdynpro applications and the logic requires calling avrious Function modules.
Do I need to create Service Call for each Function module or call them directly.
It would be great if you can suggest me under what cases I need to opt for Service call
For example, if I use 'RP_CALC_DATE_IN_INTERVAL', do I need to use Service call or call function module directly.
Note: I have searched forums but could not get the correct answer which I want
Thanks!

The Service Call is really meant to be a wizard/time saver. It has the advantage that it can generate matching context nodes/attributes for the interface of the Function Module you are calling. However everything that the service call does can also be created by hand.
Personally I'm not a fan of what the service call wizard generates. Its good as a time saver or for beginners, but I find I prefer to touch up the code it generates anyway. I much prefer to create a nice reusable model class with its own unit test and then consume this model class (with the service call wizard) from WD. This model class might contain one or more function module calls depending upon what logic I need to access.

Calling Function Module in Update Task

Hello Experts,
Can anyone let me know about
Calling Function Module in Update Task.
Why do we use this " In Update Task " ??
How do we Use ??
What is the Use... ??
Kindly let me know....
Thanks and Regards
Pramod

hi,
Why do we use this " In Update Task " ??
The main update technique for bundling database changes in a single database LUW is to use CALL FUNCTION... IN UPDATE TASK.
How do we Use ??
A typical R/3 installation contains dialog work processes and at least one update work process. The update work processes are responsible for updating the database. When an ABAP program reaches a COMMIT WORK statement, any function modules from CALL FUNCTION... IN UPDATE TASK statements are released for processing in an update work process. The dialog process does not wait for the update to finish. This kind of update is called asynchronous update.
What is the Use... ??
Asynchronous update is useful when response time from the transaction is critical, and the database updates themselves are so complex that they justify the extra system load
Real time scenario.
Suppose a user wants to change an entry in a database table, or add a new one. He or she enters the necessary data, and then starts the update process by choosing Save. This starts the following procedure in the ABAP program:
Firstly, the program locks the database entry against other users, using the enqueue work process (or the message server in the case of a distributed system). This generates an entry in the lock table. The user is informed whether the update was successful, or whether the lock could not be set because of other users.
If the lock is set, the program reads the entry that is to be changed and modifies it. If the user has created a new entry, the program checks whether a record with the same key values already exists.
In the current dialog work process, the program calls a function module using CALL FUNCTION... IN UPDATE TASK, and this writes the change details as an entry in table VBLOG.
When the program is finished (maybe after further dialog steps), a COMMIT WORK statement starts the final part of the SAP LUW. The work process that is processing the current dialog step starts an update work process.
Based on the information passed to it from the dialog work process, the update work process reads the log entries belonging to the SAP LUW from table VBLOG.
The update work process passes this data to the database for updating, and analyzes the return message from the database. If the update was successful, the update work process triggers a database commit after the last database change and deletes the log entries from table VBLOG.
If an error occurred, the update work process triggers a database rollback, leaves the log entries in table VBLOG, flags them as containing errors, and sends a SAPoffice message to the user, who should then inform the system administrator.
The corresponding entries in the lock table are reset by the update work process.
Hope this is helpful, Do reward.

Call function module in backgrouns task and in update task

Hi Gurus,Pls crear me on the " <b>Call function module in backgrouns task and in update task</b>".
how it works and waht is the link with LUW releated to these .
also heard that commit work statement aslo linked with this.
Pls clarfiy me with expalnation of code.

Hi sridhar,
the explanation already given is correct and good. Small add-on:
All functions called during one LUW with addition IN UPDATE TASK are stored together with their actual parameters in a temporary memory area. The moment a COMMIT WORK is issued, the functions are released to be executed by a so-called update task which is running in the background. This explains why functions called in update task never return anything, no SY-SUBRC and no export or table parameters If a function called in update task raises an exception or runs into an error the calling user will get an express message informing about this. Also, all database updates done by this update process are rolled back to keep consistency.
This proceeding helps to keep database tables consistent and allows the user to keep on doing his work before all database updates are complete. You may have seen messages like "material will be changed" after saving. If you open the same material immediately, you'll get a message "object locked by...<yourself>". This means the update task is still running.

Clemens

Error BT616 when calling function module SXPG_COMMAND_EXECUTE in background

Hi All,
We use function module SXPG_COMMAND_EXECUTE with a custom command we defined in SM69 to move files in unix (mv command).
The function module call has worked fine for almost a year and recently we have been seeing an error (BT616) in our job lob (SM37) when the program is run in background. We have not been able to reproduce the error in foreground mode and it seems to be occuring only periodically in the background. (The appropriate SAP authorization objects where assigned to the batch job ID and the steps on the batch job.) We are in the process of setting up the trace flag and performing analysis on the trace log via ST11 to help identify the issue.
After perform analysis on SXPG_COMMAND_EXECUTE, the error is occurring when calling function module SAPXPG_END_XPG for exception 2, system failure, yet function module SAPXPG_END_XPG does not exist. I assume this is a program at the operating system level and is just a signature of the parameters to be passed to the operating system program.
Below is part of the SAP function module SXPG_COMMAND_EXECUTE that is failing.
* Now we have to wait for the termination of the external
* command if the caller wants us to.
    IF TERMINATIONWAIT = 'X'.
      CALL FUNCTION 'SAPXPG_END_XPG'
        DESTINATION DESTINATION
        IMPORTING   EXITSTAT = STATUS
                    EXITCODE = EXITCODE
        TABLES      LOG      = LOG
        EXCEPTIONS COMMUNICATION_FAILURE = 1 MESSAGE MSG
                    SYSTEM_FAILURE        = 2 MESSAGE MSG.
I performed a where used on function module SXPG_COMMAND_EXECUTE, and most of SAP programs call the function module with the parameter TERMINATIONWAIT = 'X', so I assume we should pass X as well.
Any ideas on what could be causing this issue?
Mike Vondran

I also remember I have this kind of issue, as I have some UNIX script at OS( UNIX) level . The problem was with the ID , as it dont have proper authorization at OS level ( UNIX ) . Please check this ID authorization. This could be the one of reasons if youre sure from SAP standpoint.
Hope thisll give you some guide line..
Thanks

Type error while calling function module with in FOX formula

Hi,
I am getting following error while calling function module from FOX Formula:
"Types of parameter DAY_IN () and variable J_CALDAY(D) are inconsistent"
Following is the code:
DATA    I_CALDAY       TYPE 0CALDAY.
DATA    N_CALDAY       TYPE 0CALDAY.
DATA    KYF              TYPE KEYFIGURE_NAME.
FOREACH   I_CALDAY, KYF.
   CALL FUNCTION SLS_MISC_GET_LAST_DAY_OF_MONTH
      EXPORTING
         DAY_IN = I_CALDAY
      IMPORTING
         LAST_DAY_OF_MONTH = N_CALDAY.
    {KYF, N_CALDAY} = {KYF, L_CALDAY}.
ENDFOR.
Import parameter DAY_IN is of type sy-datum (that inturn is data element SYDATUM of data type DATS - same as 0CALDAY). Not sure why error is being thrown. Any idea? Thanks.
Edited by: SAP_BOY on Dec 4, 2009 5:26 PM

Hi,
I think It will not identify ,though you have (data element SYDATUM of data type DATS - same as 0CALDAY).Check it out by assigning it through a variable of type D.
Data I_CALDAY TYPE D.
Hope it may work out.

Can we call function modules in SAP query or ADHOC query

Hi ,
Can we call afunction moudule in sap query or ADHOC query ?If yes How
An early responce is greatly appreciated
Thanks and best regards
Rajeev Chhabra

Hello Rajeev Chhabra,
Yes; you can call function module in SAP Query. In InfoSet definition (SQ02), you can create additional field. In this field definition, you can add code snippet where you can function module.
However, this is not possible in Quick Viewer (SQVI) Query.
Thanks,

Then use process type "ABAP Program" in your process chain and add the program you have created. So then this program will be executed via process chain and this program will call the function module.
