Calling a function in tasks

HI gurus
Is the following implementation in-correct. This for me should be creating invoices as the function module YSHELL_INCOMING is calling a bapi inturn...however I do not get any tables filled and there is no return in the return table.
DO 5 TIMES.
WRITE SY-INDEX TO V_TASK.
CALL FUNCTION 'YSHELL_INCOMING'
      STARTING NEW TASK V_TASK
       performing set_function1 on end of task
       EXPORTING
            HEADERDATA       = G_INV_HEADER
       TABLES
            ITEMDATA         = G_INV_ITEMDATA
            ACCOUNTINGDATA   = G_INV_ACCDATA
            GLACCOUNTDATA    = G_INV_GLDATA
            WITHTAXDATA      = G_INV_WITHTAXDATA
            RETURN           = G_INV_RETURN.
ENDDO.
form set_function1 using taskname.
receive results from function 'YSHELL_INCOMING'
          IMPORTING
            INVOICEDOCNUMBER = G_INVOICE
            FISCALYEAR       = G_FYEAR.
endform.
endform.

Pretty sure you need to WAIT till its done. Here is an example program using the WAIT.
report zrich_0001.
data: functioncall1(1) type c.
constants: done(1) type c value 'X'.
data: cstgdetail1 type bapicustomer_kna1.
parameters: p_kunnr1 type kna1-kunnr.
start-of-selection.
call function 'BAPI_CUSTOMER_GETDETAIL2'
           starting new task 'FUNC1'
             destination 'NONE'
              performing set_function1_done on end of task
    exporting
      customerno                  = p_kunnr1.
* Receive remaining asynchronous replies
wait until functioncall1 = done.
write:/ cstgdetail1.
*       FORM FUNCTION1_DONE
form set_function1_done using taskname.
receive results from function 'BAPI_CUSTOMER_GETDETAIL2'
   importing
      customergeneraldetail       = cstgdetail1.
functioncall1 = done.
endform.

Windows 8.1 background task Javascript - Call angular controller function from task js

Hi,
The Ionic Side menu starter template for windows 8.1 is a very good option to run the ionic apps on Windows 8.1 phones.
I am not sure whether this is related to Ionic/angular or VS2013 CTP 3.1 but if anyone can give some tips ,that would be great. I registered a background task as per the VS tutorial (Run JS task in background) and i tested it with windows toast notifications.However
my requirement is to access webservice in background which I am not able to implement.
The setup for background task is path to the js file but my requirement is to call a function defined within a controller.Is there any way i can access the controller function from an outside js file.I am new to Ionic,Angular and VS 2013.Any help would be great
The structure of background task js file is as below
(function() {
--- I need to call my controller/service function here---
var notifications = Windows.UI.Notifications;
var template = notifications.ToastTemplateType.toastImageAndText01;
var toastXml = notifications.ToastNotificationManager.getTemplateContent(template);
var toast = new notifications.ToastNotification(toastXml);
var toastTextElements = toastXml.getElementsByTagName("text");
toastTextElements[0].appendChild(toastXml.createTextNode("From Background!"));
var toastNotifier = notifications.ToastNotificationManager.createToastNotifier();
toastNotifier.show(toast);
close();

Are there any updates on this issue? I'm currently seeing this on a Lumia 822 with WP8.1, and the app has never been published to the store. I've only ever deployed the app from Visual Studio to my device. It worked when deploying the Debug build, then I
tried a Release build, and it crashed immediately upon launch when trying to register the background task, but then I was able to go back to deploying/debugging the Debug build on the device for awhile. I made more changes, and now neither Debug nor Release
builds work--both fail on the BackgroundTaskBuilder.Register() call with the error described in the original question:
"The drive cannot locate a specific area or track on the disk. (Exception from HRESULT: 0x80070019)"
I've tried changing the Task name during registration, rev-ing the version number of the application, adding the call to BackgroundExecutionManager.RemoveAccess() before BackgroundExecutionManager.RequestAccessAsync(), changing the name of the IBackgroundTask
concrete implementation and changing the corresponding EntryPoint in the package.appxmanifest (as well as in the BackgroundTaskBuilder instance), and changing the package DisplayName to a new reserved name, all to no avail. The only thing I didn't try
was associating with an entirely new app in the app store or paving my phone, as these are both fairly undesirable "workarounds."
Even if this won't affect clients downloading the app from the store, this is a major roadblock during development, as we can essentially only use the emulator to test an app specifically designed to help solve problems involving moving around physically
in the real world.
Any more information would be greatly appreciated. If there's any information I can provide, please let me know.

Call function - New task

Hi Everyone,
I would like to use the Call Function - New task for one of my requirments. Please suggest if I am not doing right.
My programs looping structure is:
LOOP at zwewa_x.
        PERFORM bapi_matphysinv_changecount.
ENDLOOP.
FORM bapi_matphysinv_changecount .
call function 'BAPI_MATPHYSINV_CHANGECOUNT'
    exporting
      physinventory             = zwewa_y-iblnr
      fiscalyear                   = zwewa_y-gjahr
PERCENTAGE_VARIANCE       =
    tables
      items                     = itab
      return                     = it_return.
ENDFORM.      " BAPI_MATPHYSINV_CHANGECOUNT
Why am I thinking to use NEW TAEK is; when normally I call the BAPI its creates so many locks on the different different tables resulting LOCK table memory issue. So I thought to use the NEW TASK addition which would run a new session and while coming back to the calling program, would release all the locks. But I am not understanding how to use the NEW TASK perfectly and how to get the values (IT_RETURN) back from the new session to the calling program.
Can anybody send me the sample code where NEW TASK statement is being used and later from the new session values or Internal tables are coming back to the calling program.
This would be a great help.

Hi,
Try this:
CALL FUNCTION func STARTING NEW TASK task
              [DESTINATION {dest|{IN GROUP {group|DEFAULT}}}]
              parameter list
              [{PERFORMING subr}|{CALLING meth} ON END OF TASK].

Window doesn't close wheh Call Library Function Node set to Run in Any Thread

This is a problem regarding Call Library Function Nodes running in the UI thread or any thread.
I have a camera which has its own API supplied as a dll. I have created a set of VI wrappers which each call a function in the dll through a Call Library Function Node.
Initially each CLFN was set to 'Run in the UI thread' (the default).
To start the camera streaming images I call (through a CLFN)
ICubeSDK_Start(int CamIndex, Hwnd, ImgHandle, bool Preview, bool callback);
If Preview = True then the image is displayed in a preview window.
If ImgHandle = NULL a default preview window
is used.
In the CLFN definition I define:
ImgHandle as a U32
Preview as a I32
To stop the camera streaming images I call
ICubeSDK_Stop(int CamIndex)
In the actual implementation I set ImgHandle = 0 (NULL) and Preview = 1 (true).
This all works fine, and a preview window is opened and images displayed. When I call ICubeSDK_Stop the preview window is closed.
However, I would prefer to set the CLFN to 'Run in any thread' because
a) when run in the UI thread the preview window randomly gets sent to the back when I switch focus between open VI windows (presumably because it is in the same thread as the VIs)
b) I don't want to put unnecessary stuff in the UI thread
c) my (naive?) understanding is that it is safer to run in any thread
So I have set all CLFNs to 'Run in any thread'
When I do this the preview window opens OK, and behaves like any other non LabVIEW controlled window in terms of focus. But when I call ICubeSDK_Stop() the preview window does not get closed properly, it just shows a blank image. I can't close it manually, there is no X in the corner and no option to close it from the taskbar. To get rid of it I have to close the LabVIEW project it is spawned from, which often results in a crash. It does appear as a separate item in task manager but if I 'end process' it, LabVIEW closes (and often crashes) as well.
If I change only the CLFNs that call the Start and Stop functions back to 'Run in the UI thread' then it all works fine again, except that the preview window gets sent to the back randomly as before.
So, what do I have to do to get the preview window to close properly if I set the CLFN to 'Run in any thread'.
Alternatively, is there a way to close the window programmatically (ie force it to close) after I have called ICube_Stop.
Thanks
DAve

Hi Dave,
The "Run In UI Thread" switches from the thread the VIs currently executing in to the user interface thread. If you select "Run in Any Thread", the Call Library Function Node continues in the currently executing thread. By default, all Call Library Function Nodes run in the User Interface thread.
Before you configure the Call Library Function Node to run in any thread, you have to make sure that the code is thread safe. Code is thread safe when it does not store any global data (e.g. global variables, files on disks, etc.), does not access any hardware, does not make calls to any functions, libraries or drivers that are not thread safe.
Unfortunately, since you said that your DLL accesses hardware, it is not recommended to use "Run in Any Thread." This is probably why you are seeing the crash.
If your preview window gets sent to the back you can programmatically bring it forward. Here is an example of how this can be done: http://decibel.ni.com/content/docs/DOC-4551
If you want to completely close the window down you can do so as described in this link: http://digital.ni.com/public.nsf/allkb/81E9C1441900FFCE8625748F0055DBB0?OpenDocument

How do I SUBMIT from a user exit which is called in an update task?

I want to send an idoc each time there is a goods movement. So, in the user exit of MB_POST_DOCUMENT I am calling IDOC_OUTBOUND_WRITE_TO_DB. This creates an idoc of status 30. However, in order to send the idoc I want to SUBMIT RSEOUT00. I get an ABAP dump on the SUBMIT because MB_POST_DOCUMENT is called in the update task, where SUBMIT is not allowed. Do you know any other way I can execute RSEOUT00 at this moment without having to call it later in batch?
Thanks!!
Joy

Hi Naren,
Your reply is VERY helpful!! Thank you so much.
I added CALL FUNCTION 'RSAP_IDOC_EINBUCHEN_VOM_BIW_4' IN BACKGROUND TASK. I am no longer getting the dump, but my idoc is still a status 03 and not a status 30. Should I expect to see it turn to a status 30? I ran this function directly in SE37 -> Test with the same parameters and it ran perfectly and turned the idoc to a status 03. Is there anything else I need to do in the code?
Thanks again,
Joy

Qs about call FM in background task, and monitoring in SM37.

Hi, guys, i got a question here, if I call a FM using addition "in background task" in a Z program, does this mean the FM process is running in background? And can I monitor my task in sm37?
i've tried to do that, the FM was successfully proceeded, but I cannot see anything related to that task in SM37 under mine user ID.

No, you cannot see that in SM37.
What it means is that the function is being executed in a seprated thread and the program that called the function will continue the execution without waiting for the function finish execution, that means the function is called in a synchronous manner.

Creation of spool for job created by calling FM in background task

Hi Gurus,
1.Wanted to confirm if it is possible to attach spool to the job that has been created by calling a function module in background task.
Currently I have created one RFC enabled FM and called it in background task. It runs fine, and the job is created which can be seen in SM37. But it does not contain the spool even if the RFC FM contains the code for list ALV.
2. Also is it possible to control the name of the job created by calling the RFC FM in background task?
Code for calling the FM is given below(ZK_XX is th RFC FM):
CALL FUNCTION 'ZK_XX' IN BACKGROUND TASK
CALL FUNCTION 'START_OF_BACKGROUNDTASK'
EXPORTING
   startdate       = sy-datum
   starttime       = sy-uzeit
NOSEND          = ' '
COMMIT WORK.
Thanks a lot for your help!!
Warm Regards,
Raveesh

Thanks for replying.
I need to do the processing in background. Hence using 'IN BACKGROUND TASK' addition.
Please let me knowif you have some idea.
Thanks & Warm Regards,

How to unrigister the call back function,in vb6 with DAQmx 8.5

I use daqmx api which named DAQmxRegisterEveryNSamplesEvent to register my call back function,When I invoke the function DAQmxErrChk (DAQmxStopTask(taskHandleAnalog)) to stop my Task.then i call the procedure AD_OPEN  again,it raise an error ,tell me that i need to unregister the event,the data has transfer into the buffer.how can i unregister the event,please look at the following code.
Spoiler (Highlight to read)
Private Sub create()
   Dim channel As String
    Dim minVoltage, maxVoltage As Double
    Dim samplesPerChannelPerRead As Double
    Dim sampleMode As Long
    Dim boolVal As Boolean
    On Error GoTo AdErrorHandler:
    ' Get values from UI controls
    channel = "Dev2/ai1:2"
    minVoltage = -10
    maxVoltage = 10
    samplesPerChannelPerRead = 100
     If (taskHandleAnalog <> 0) Then
         DAQmxErrChk (DAQmxStopTask(taskHandleAnalog))
        DAQmxErrChk (DAQmxClearTask(taskHandleAnalog))
        taskhandle = 0
    End If
    ' Configure the task
    DAQmxErrChk (DAQmxCreateTask("", taskHandleAnalog))
     DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandleAnalog, "Dev2/ai0", "", DAQmx_Val_InputTermCfg_RSE, minVoltage, maxVoltage, DAQmx_Val_VoltageUnits2_Volts, vbNullString))
    DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandleAnalog, channel, "", DAQmx_Val_InputTermCfg_Diff, minVoltage, maxVoltage, DAQmx_Val_VoltageUnits2_Volts, vbNullString))
End Sub
Private Sub AD_Open()
    DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandleAnalog, "", 200, DAQmx_Val_Rising, DAQmx_Val_AcquisitionType_ContSamps, samplesPerChannelPerRead))
    'Find number of samples specified
    DAQmxErrChk (DAQmxGetTaskNumChans(taskHandleAnalog, numChannels))
    'Configure Event Callbacks
    DAQmxErrChk (DAQmxRegisterEveryNSamplesEvent(taskHandleAnalog, 1, 4, 0, AddressOf EveryNSamplesEventHandler1, Nothing))
ReDim dataBuffer(numChannels * samplesPerChannelPerRead - 1)
    ' Start the DAQmx Task
'    DAQmxErrChk (DAQmxCfgDigEdgeStartTrig(taskHandleAnalog, "/Dev1/PFI2", DAQmx_Val_Edge1_Falling))
    DAQmxErrChk (DAQmxStartTask(taskHandleAnalog))
    ' Update UI
    Exit Sub
AdErrorHandler:
    MsgBox Err.Description
End Sub

This may be a bit late, so hopefully you found this on your own. But in order to unregister the event pass a null value for the callback function parameter in the DAQmxRegisterEveryNSamplesEvent function (Nothing in VB).

How to call a function in the background in WDA?

__The requirement is__
call the function XYZ from Webdynpro ABAP program to run in the background and user doesnt have to wait to finish it, but can work on other screens/transactions.
1. Should function XYZ be remote-enabled?
2. Will CALL function XYZ in background task work?
Points will be rewarded. Thanks.

Hi John,
I guess you will have to use the asynchronous RFC for your requirement.
So that this FM can be called frm WD applicaiotn and due to asynchronous nature, it has no relation with other user actions which are going on .
You can check this

Dot source/calling a function with switch from the cmd line

Hi
This is driving me crazy and I know its something really obvious.
If I have an example script like so, called myexample.ps1
[CmdletBinding()]
param
[Parameter(Mandatory=$false, HelpMessage="My Switch")]
[switch] $Myswitch,
[Parameter(Mandatory=$false, HelpMessage="Email Address")]
[string] $email
Function Main
[CmdletBinding()]
param
[switch] $Myswitch,
[string] $email
if ($Myswitch)
Write-Host "Switch Enabled"
Write-Host "Email is $email"
else
Write-Host "Switch Disabled"
Write-Host "Email is $email"
Main -email $email #This is the line that I think is at fault
I have two issues
1) How do I correctly write the code so that the script can be called with either or both parameters. The switch ($Myswitch) is the one that is really causing me issues.
2) Is invoking it the easiest method/best/most common method of calling it via a batch file
Here's my understanding
a) I could dot source it (. .\myexample.ps1) to load the functions into the current session, then call the function
Main -email hello.com -Myswitch
or
Main -email hello.com
b) or I could Invoke it, which I think is my preference as my final goal here is for it to be called via a batch file in a scheduled task
& 'C:\Users\myusername\Desktop\MyExample.ps1' -email hello -myswitch
or
& 'C:\Users\myusername\Desktop\MyExample.ps1' -email hello
Any push in the right direction will be appreciated :)

Why the function? Just call the file. We don't "Invoke" scripts. Just call the script..
# MyExample.ps1
[CmdletBinding()]
param(
[Parameter(Mandatory=$false, HelpMessage="My Switch")]
[switch] $Myswitch,
[Parameter(Mandatory=$false, HelpMessage="Email Address")]
[string] $email
if ($Myswitch){
Write-Host "Switch Enabled"
Write-Host "Email is $email"
}else{
Write-Host "Switch Disabled"
Write-Host "Email is $email"
Now jsut call it like a normal script:
.\MyExample.ps1 -email someemail -MySwitch
It is as simple as that.
If it has to be a function as in a library then you must either dot source or create a module.
¯\_(ツ)_/¯

Call transaction inside Update task

<b>Is it possible to use call transaction inside an update function module?</b>
My requirement is like this.
When I execute LB10 storage units will be created..then we have to go to lt09 and then create a TO's there for all these Storage units..
Now, when I try to call a bdc session from an exit, the storage units are not updated there. so the BDC is getting failed..
To resolve this, I kept all the BDC code in to a Zfunction module and made it an update funtion module. I am calling this function module form the exit IN UPDATE TASK.
But the call transaction is not working....
I have tried with L_TO_CREATE_MOVE_SU inside the Z function module..Still no use..
is there any other way that I can solve this?

Hi,
Calling a FM in Update Task is one of the bundling techniques used in ABAP to avail functionality provided by SAP Update System. Here all database updates are processed at the end of the SAP LUW in contrast to normal FM call where the database updates are done and commited at the time of call (Database LUW). It is necessary to bundle all your database updates in an SAP LUW e.g. all database updates in a transaction (like VA01) should be bundled. Almost all standard SAP transactions use bundling techniques.
This technique separates the dialog process and update process. The dialog part of the transaction can span more than one screen(one dialog step) and can be processsed by more than one dialog work process. A work process is released when the dialog step changes (screen changes) and the work process sends a database commit (called Implicit Database LUW). So with each screen change there is a database commit and database remains in consistent state.
Now when using bundling technique, when a COMMIT WORK is encountered, system ends the dialog process with a dialog work porcess and starts the update process using an update work process.
The dialog step containing the COMMIT WORK is considerd as the last dialog step of the transaction and all the update function modules are processed now in the last dialog step by the update work process though they were called earlier during the earlier dialog steps.
It is necessary to create update FMs to take advantage of this technique. The update FM is created FM by setting the Update moduleradiobutton in the Attributes tab in SE37.
In a normal FM call, if there are database updates (UPDATE, INSERT, MODIFY, DELETE) than database is commited after the FM processing is over as the FM starts its own Database LUW and ends it too.
<b>Reward Points</b>

Update termination error while calling FM in Update task

Hi Friends,
I am calliing my Z Function Module in update task from my report, my function module contain reuse alv list display fm which should create a Spool in the spool list.
When ever i am directly executing my Z function module i am getting spool in SP01, but when ever i am calling the Z Function Module in update task from my report i am getting a message as "Express document "Update was terminated" received from author.
I want to call the Function module in update task and it should generate spools .
Syntax:
CALL FUNCTION 'ZLOK_TEST' IN UPDATE TASK.
Commit work.
Thanks Regards,
Sandipan jena

Hi sandipan jena,
a function called in update task will not create a spool list if not told so to to. Only reports scheduled in a JOB will put the output into spool.
Make sure you have no COMMIT WORK and no MESSAGE output when in UPDATE TASK. You can enter /h and in debugger switch on UPDATE debugging. This will lead you to any error occurring.
You should analyze the errors you get. Mabe NEW-PAGE PRINT ON can help you.

Clemens

Problem when using Call FM IN UPDATE TASK.

we plan to update ztable using Call FM in update task, and write the success/error message into log.
Does below is right?? I found the commit work can not be used here. Thanks..
CALL FUNCTION 'ENQUEUE_ETABLE'.
IF sy-subrc = 0.
CALL FUNCTION 'update_ztable'' IN UPDATE TASK.
Endif.
COMMIT WORK and wait.
IF sy-subrc <> 0.
     ROLLBACK WORK.
     write error log.
Else.
    Write successful log.
Endif.
CALL FUNCTION 'DNQUEUE_ALL'.

Hi ,
Please see the refernce of UPDATE FUNCTION MODULES:
UPDATE FUNCTION MODULE
-In the attributes tab, under processing type, choose Update Module,
Start Immediately. Define your import parameters, enter the source
code, All validations should have been done prior to the call to this
function module, so all you need in the source, is the updating of the
database, INSERT, MODIFY, UPDATE, whatever.
-When you call you function module, use IN UPDATE TASK, after the call,
COMMIT WORK. The commit work will trigger the db update.
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.
Q:We are calling Sales Order Change in update task inside the user Exit MV50FZ1. We can see that the FM is called in update task after the commit work and the return of the FM shows the success message. But still the changes are not saved to the DB.
A: check sm21 or sm13 to see if the update was successful .. In SM21 I checked. It is giving me the error Transaction Failed

ODI Error - Calling a function in the source database

I am using this directly in the Interface mapping and getting the following error
This is the syntax I am using SUM(CASE WHEN ((main.getCertDate(person_id,getdate()) >= current_timestamp) THEN 1 ELSE 0 END)
ODI-1228: Task Load_Fact_Table1 (Integration) fails on the target MICROSOFT_SQL_SERVER connection SQLSERVER_USA.
Caused By: java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Cannot find either column "main" or the user-defined function or aggregate "main.dbo.getCertDate", or the name is ambiguous.
Am I missing any additional steps, before calling a function in the mapping. Do I have to do something in the model to include teh function etc., Please help in fixing this issue.
Thanks for your time and help.
