CALL FUNCTION in UPDATE tasl

Hi all,
I am calling a Z FM in update task from MB1B exit .
When I am using the VPN cllient , the FM is getting trieggered properly , but while using the MetaFrame Presentation Server i.e. Citrix client server , The FM is not getting triggered
Does Update task work only while a VPN client ???
Any specific settings required while in Citrix ?
Thanks
Supriya

No.....it should work for all the scenario's.............Nothing specific about Citrix...........Is the FM is an RFC or is it trying to read a file from the Presentation server?
The only difference in VPN & Citrix is the PArtner Desktop...rest all is same...

Call function '' in update task - code inside is BDC

hi to all,
in using call function '' in update task
the code inside is bdc. is this possible?
my scenario is from VA01 then post billing to VF01,
i am using user-exit MV45AFZZ in subroutine userexit_save_document.
i need to post billing after va01 save.
thanks to all.

To debug in the update task, you have to set that option on in the debugger.
If the user exit runs in the update task, then you must have something like: CALL FUNCTION MODULE my_fm_to_do_BDC STARTING NEW TASK. ( This function module should wait until the SD is created. You might want to check in a loop, with a WAIT command. Once it is created, then you start your BDC and CALL TRANSACTION. ) This is NOT an update function module. It may need to be RFC enabled - I'm not certain at the moment.
If the user exit doesn't run in the update task, you need to create, and call from the user exit, an update function module that calls your function module "my_fm_to_do_BDC" STARTING NEW TASK.
The attribute "collective run", which is V3, means that the update task won't run that function module until a regularly scheduled job on the application server runs. For processing to run during the rest of the SD save, you must use V1 (could be run in any order with other V1s) or V2 (Will run after V1, but in any order with other V2s). Typically, I use V2 for this kind of task.

Hi,
look F1 to call function pls:
It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task.
-> so in error case you can analyse err. with TA SM13
(update records)

Call Function in Update task

I have written the FM Call function 'COMMITROUTINE' in update task.
but this FM is not getting triggered when some commit happens. In all, this FM is not commiting tha data in the table.
CALL FUNCTION 'COMMITROUTINE' IN UPDATE TASK
EXPORTING
lt_dfkkbrlevyrec = lt_dfkkbrlevyrec
and the
What is missing in it?
Regards,

Hi,
if you want to call your FM when a commit happens you should write a routine which is called upon commit and this routine will call your fm.
e.g
form call_my_fm .
CALL FUNCTION 'COMMITROUTINE' IN UPDATE TASK
EXPORTING
lt_dfkkbrlevyrec = lt_dfkkbrlevyrec
endform.
perform call_my_fm on commit.
commit work. " now your routine will be called

Call function in update task empty variables error

Hello,
I'm experiencing a weird error while using the addition "In update task".
My Scenario is the following:
Use the bapi_goodsmvt_create -> if there are no errors, fill some values and call my function and then commit everything.
The problem is, when the function runs in update task, all import parameters are empty!
Also, this only happens in the following code structure
CALL METHOD run_migo( IMPORTING bapireturn = t_bapireturn).
IF t_bapireturn IS INITIAL.
CALL METHOD save_custom_tables. "this runs my function 'IN UPDATE TASK'
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
 EXPORTING
 wait = 'X'.
ENDIF.
if I commit inside the method SAVE_CUSTOM_TABLES, the data is passed normally to the function, if I commit like the code above, everything is empty.

Here's the code:
METHOD save_partial.
DATA: t_wegritm LIKE gt_wegritm,
 t_tegrp_parc TYPE TABLE OF ztegrp_parc,
 w_tegrp_parc TYPE ztegrp_parc,
 w_tegrk_parc TYPE ztegrk_parc.
FIELD-SYMBOLS <w_wegritm> LIKE LINE OF t_wegritm.
t_wegritm = gt_wegritm.
DELETE t_wegritm WHERE mengee IS INITIAL.
CHECK NOT t_wegritm IS INITIAL.
*-->save xml iten
LOOP AT t_wegritm ASSIGNING <w_wegritm>.
 MOVE-CORRESPONDING <w_wegritm> TO w_tegrp_parc.
 w_tegrp_parc-id = gw_tegrk-id.
 w_tegrp_parc-gr_docto = <w_wegritm>-gr_docto.
 w_tegrp_parc-gr_mjahr = <w_wegritm>-gr_mjahr.
 w_tegrp_parc-gr_zeile = <w_wegritm>-gr_zeile.
 APPEND w_tegrp_parc TO t_tegrp_parc.
ENDLOOP.
MOVE-CORRESPONDING gw_tegrk TO w_tegrk_parc.
CALL FUNCTION 'Z_SAVE_PARTIAL'
 IN UPDATE TASK
 EXPORTING
 iw_tegrk_parc = w_tegrk_parc
 TABLES
 it_tegrp_parc = t_tegrp_parc.
ENDMETHOD.
I tried to re-create this scenario with a local class, but the code that I originally sent worked(the commit work outside of the routine).

Is It Possible to use Call Function in update task in perform on commit

Hi Friends,
I have to send an email once the commit work is done. so i am writing code like this,
Perform send_email on commit.
form send_email.
call function 'SO_NEW_DOCUMENT_SEND_API1' in update task
endform.
endform.
.... ( Some other code)
commit work.
But, I am getting error saying Update task is not possible. Please suggest me how to solve this.
Thanks in Advance,
Phani.

Hi Phani,
Check whether COMMIT Work has be performed. I think this might be the problem.

Calling function in Update Task problem

Hello Friends,
I'm calling FM 'REVISION_LEVEL_POST' in Update Task to insert a revision level for a material when saving a Change Master (CC02 T-Code). But the calling is triggered a bit early (Before updating the Data Base AEOI Table!). An Update Task FM is called right after the COMMIT WORK is executed. Here in my case, a commit work is done but not for my change Master but for a text... So my FM does not find the record to be updated.
Is there a way to solve this ?
Thank you for your Help!

Call Function

Hi,
Can any one detail the exact difference between Call Function and Call Function in Update Task.
Regards,
Sreedhar

CALL FUNCTION func IN UPDATE TASK.
Extras:
1. ... EXPORTING p1 = f1 ... pn = fn
2. ... TABLES p1 = itab1 ... pn = itabn
Effect
Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task. Update function modules must be flagged as such in the Function Builder
The return value is not set.
Addition 1
... EXPORTING p1 = f1 ... pn = fn
Effect
Values of fields and field strings specified under EXPORTING are passed from the calling program to the function module. In the function module, the formal parameters are defined as import parameters. In the interface definition, default values must be assigned to all import parameters of the update function module.
Addition 2
... TABLES p1 = itab1 ... pn = itabn
Effect
TABLES passes references to internal tables. All table parameters of the function module must have values.
Note
With update function modules, both import parameters and exceptions are ignored when the call is made.
During updating processes of function modules, you may not make any calls using the language statements SUBMIT, CALL DIALOG, CALL SCREEN, CALL TRANSACTION, COMMIT WORK or ROLLBACK WORK . All other language elements that trigger a database Commit (for example, a screen change using the MESSAGE statement) also lead to a runtime error during updating.

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.

Call function module in update task

Hi
I am using the follwoing logic in my prog
CALL FUNCTION 'Z_Update _Task'    In update task

Here am giving some information abt UPDATE TASK.
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

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.

Wht is UPDATE TASK functionality in CALL FUNCTION??

Hi Experts,
Pls. clarify one of my simple doubt that, Wht is the functionality of UPDATE TASK, in following sttement?
call function 'Z_FM_1' in update task
I found SAP help as follow, but not understood??
Flags the function module func for execution in the update task. It is not executed at once, but the data passed with EXPORTING or TABLES is placed in a database table and a subsequent COMMIT WORK then causes the function module to be executed by the update task. Update function modules must be flagged as such in the Function Builder
The return value is not set.

Hi,
It sounds like the FM was not called but it was (rollback process).
And what is the difference between an update attribute assigning FM and this?
You control the FM update process by setting the update module attribute.
- Update with immediate start
Set this option for high priority ("V1") functions that run in a shared (SAP LUW). These functions can be restarted by the update task in case of errors.
- Update w. imm. start, no restart
Set this option for high priority ("V1") functions that run in a shared (SAP LUW). These functions may not be restarted by the update task.
- Update with delayed start
Set this option for low priority ("V2") functions that run in their own update transactions. These functions can be restarted by the update task in case of errors.

Ferry Lianto

Call function module in backgrouns task and in update task

Hi Gurus,Pls crear me on the " Call function module in backgrouns task and in update task".
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.
Regards,
Clemens

RE:CALL FUNCTION update_function IN UPDATE TASK

Hi,
Can anyone give a sample code or a simple scenario for CALL FUNCTION update_function IN UPDATE TASK .
Thanks in advance,
Alex.

Hello George
In a project dealing with material master data I had the problem that I needed to update standard as well as customer tables at the same time when the user pushed the SAVE button.
For the standard tables I used BAPI_MATERIAL_MAINTAINDATA_RT (retail material) and for the customer tables I created my own SAVE function modules.
How to ensure that either both (standard and custom) tables are updated or not simultaneously?
I created a special SAVE function module which called both the standard BAPI and my custom SAVE function modules.
This "wrapper" SAVE function module was then called IN UPDATE TASK.
This way I created a LUW (logic unit of work) which comprised both standard and custom tables. If everything was ok both types of tables were updated, otherwise the entire transaction was rolled back.
