Execute CL_GUI_ALV_GRID in background

Hi. I am using method CL_GUI_ALV_GRID->SET_TABLE_FOR_FIRST_DISPLAY to display an ALV report. I have put this method in the PBO of a screen and first create a container from a custom container on the screen.
This works fine in the foreground, but in the background I am getting a dump when creating the container, saying that the "GUI can not be reached".
Is there any way of getting this to work in the background?
Thanks a lot for your help,
Dave.

David,
Check IF CL_GUI_ALV_GRID=>OFFLINE( ) IS INITIAL. Then create the container
This will convert the grid to a list in the background.
Example
CLASS-DATA list TYPE REF TO cl_gui_alv_grid.
IF CL_GUI_ALV_GRID=>OFFLINE( ) IS INITIAL.
CREATE OBJECT g_custom_container
EXPORTING container_name = g_container.
ENDIF.

Front-end functions cannot be executed in the background in SM37

Hi ,
I have developed a BDC program for Tcode HRUSER . The program is working fine in Frontend but when Executed in Background through SM37 gives a error -:
"Front-end functions cannot be executed in the background".
I am not using any function like GUI_DOWNLOAD or anything like that .
Thanks
Nikhil Arya.

Hi ,
No , the program is not taking any inputs from the user .
when i am executing the program in background mode it is just showing the messages at the end which i am writing in the program for eg:
"creating a user for employee 2306328".
So , only the list of messages comes at the end .
Thanks

Restrict 'Executing report in background' from selection screen

I want user to not to select option for executing report in background from Selection Screen of the program.
i.e. 'Execute Program in Background' option in 1st menu bar tab should either be disabled OR if user clicks on it then he should get error message on selection screen itself.
Thanks,
Falguni

Hi Falguni,
Write the code based on function code SJOB in the event AT SELECTION-SCREEN. Write the following code :
AT SELECTION-SCREEN
CASE SY-UCOMM.
WHEN 'SJOB'.
MESSAGE E000 WITH 'You cannot schedule background job'.
ENDCASE.
Thanks & Regards,

Execute listcube in background - where is the file stored on app server

Hi,
I want to execute listcube in background.
to execute in background, the only output option available is Store in file (appl server).
My question is where is this file stored.
there is no information in the job log nor is there any spool.
Also, can I determine myself where is this output file written.

I have a couple of questions that could lead to an answer to your question...
Does your BW environment have one or more application servers, in addition to the Database Central Instance (DBCI)? If so, do you use logon groups for SAP Logon so that the logon loads are balanced?
I'm asking these questions because if you have a multiple application server environment and logon balancing, you may not be logging onto the same server every time that you're executing LISTCUBE and it will save to the directory path of the server you're logged onto.

Issue with How Do I Run an Executable in the Background ?

Hi,
I am trying to run a LabVIEw executable in the background, but none of the methods described in the discussion forum and on ni.com seems to be working. I am using LV 2011 on a Win 7 64-bit machine in case this matters.
I tried the method described in "How Do I Run an Executable in the Background as a Start-Up Application?" (http://digital.ni.com/public.nsf/websearch/4A8B626B55B96C248625796000569FA9?opendocument&Submitted&&... but I still see a fragment of a window at the bottom near the start-button (Exhibit 1). Exhibit 2 shows that it only consists of the title bar. (I have customized the window appearance as described, and added the two items
HideRootWindow=True
UseTaskBar=FALSE
to the *.ini file.)
I also tried disabling all the other items in the Customize Window Appearance menu with the same result.
Then I tried the method described in "Running a LabVIEW Executable as a Background Process" (http://digital.ni.com/public.nsf/allkb/EFEAE56A94A007D586256EF3006E258B) adding the FP.Open method to the VI and setting the state to hidden. I got the same result (Exhibit 1).
Is there anything I need to do in addition or different for my windows version? I appreciate your help. Thank you.

Execute calc in background not working

Essbase version 9.3.1 running on Red Hat Linux. When I'm in EAS and check the "Execute in the background" box I get the message if what launched in the background with a Process ID but no calc kicks off, nothing in the app log file, nothing shows up when I look at background processes, no session when I look at server. The calc runs fine if I don't select to run in the background.
Anyone else run across this or am I missing something?

I had the identical issue and received the below fix from Oracle Support, which worked. I thought I'd put the fix up here, since the forums were my first stop when I had the problem.
1. There will be a file called Workstatus.xml in the EAS server
2. Search for this file
3. Rename the file or cut and paste this file to a different location.Restart the EAS server
4. Run the calc in background it will work fine
And it did! This was on Windows Server 2003, Essbase 9.3.1.2.
Thanks,

Error while executing program in background

We have a program to upload data to the presentation server in the xml file format.
It is working fine in foreground.But whenever we are trying to execute it in the background it gives error:
'Error in control framework'.

Prem,
Looking at the error that you have shown, looks like its a different error. Is there a control/GRID that is being used in the program.
If you are using a CUSTOM CONTAINER and a GRID to display the data, whenever you executing the program, you should not create the container. Something like this ..
    if cl_gui_alv_grid=>offline( ) is initial.
      create object CUSTOM_CONTAINER
             exporting container_name = CUSTOM_CONTROL
    endif.

Execute BEx as background job

Hi Guys,
User hit abap dump for TIME_OUT when executing query in Analyzer by selecting All data.
I understand it is standard setting of 600 seconds for dialog processing.
Is there anyway i can execute the query in background when user select all data?
I google and found out something about report agent, but is there any guide or manual to use that?
Thanks.

User must have got this error while running the query in web.
Ask use to run the query in BEx Analyzer.
We faced an similar issue where query in web was giving time out error but in analyzer I was to run it and it was taking around 60 minutes.
Similarly with broadcast, if you do it web broadcast, you will get the time out error. You will have to go with Workbook broadcasting.
Or suggest user to run the query multiple times with smaller selection.
Or try creating a workbook with multiple sheets restricted for differetn values, thus time taken should be less and all the data will be available in mulitple sheets which can be merged later and advantage is that workbook is to be run only once as compared to run the query mulitple time.

How to execute report in Background from Dialog process?

How, or what is the best way, to lauch an executable program (report) into the background from a dialog program (dynpro)?
<b>Example:</b> The SUBMIT...AND RETURN still executes the called program before it returns control to the calling program. I just want the report to be kicked off and the dialog to continue as normal. I do not want the report execution time to affect the dialog process.
Thanks in advance for your time.

Hi Nablan, I'm also trying to do parallel processing and created a function module that kicks of another report program.
However, the process doesn't seem to work. The Main program runs from start to finish but the called program in the function module doesn't seem to run. When I used the option STARTING NEW TASK task name the code ran but in the foreground. I don't want to use this option as it runs in the foreground and SAP limits one to six sessions. Is there something I'm missing in the attributes of the function module I created. Currently the attributes are: Processing type Remote enable module and it's set to start immediately. I had used Normal function module initially but this did not work with the STARTING NEW TASK task name option.
Below are the codes segements I used.
In my main program I have the following code segement
CALL FUNCTION 'Z_CA_PROG_CALL'
IN BACKGROUND TASK
EXPORTING
    zprogram            = 'ZCA_TEST1'
EXCEPTIONS
    program_call_failed = 1
    invalid             = 2
    OTHERS              = 3.
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
COMMIT WORK.
In the function module I have the following code.
FUNCTION z_ca_prog_call.
""Local interface:
*" IMPORTING
*"     VALUE(ZPROGRAM) LIKE ZCA_INTERFPROG-ZPROGRAM
*" EXCEPTIONS
*"      PROGRAM_CALL_FAILED
*"      INVALID
SUBMIT (zprogram).
IF sy-subrc <> 0.
    CASE sy-subrc.
      WHEN 1.
        RAISE program_call_failed.
      WHEN OTHERS.
        RAISE invalid.
    ENDCASE.
ENDIF.
ENDFUNCTION.

Error while executing BDC in background.

Hi
I have written a program that creates a background job to execute a BDC on Transaction CKMPRPN. This transaction is used to update future price of Materials. When this program is executed in foreground it works perfect. But when it is executed in background it throws these error messages. Same error messages are displayed when I process the BDC recording in background.
Enter at least one plant
Enter at least one plant
Spool request (number 0000023938 ) created without immediate output
No batch input data for screen SAPMSSY0 0120
Can anyone tell me why this problem is occuring only during background execution?
Or Do I need to find out a Function Module to update the future price of materials?

Thanks Kris,
Its a useful answer.. But unfortunately in 4.6C version we dont have this option of 'simulate background mode'.
Anyways.. I was able to find the solution.. I used call transaction and executed the BDC program in background and it worked. Earlier I was executing a single transaction for set of materials. But now I m executing separate transaction for each material. It gives these messages at every execution but it also updates the database. Dont know how..
