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
Nikhil Arya.

"Error:The search cannot be executed because the table has pending changes that would be lost", after DELETE

Good day,
On Search Page, I have searched for the record(s) then deleted a record and got confirmation message i.e. Record has deleted. Next when I search for any record I'm getting below error.
Error
The search cannot be executed because the table has pending changes that would be lost.
Could you please help me to fix this issue. Your response is highly appreciated.

Search cannot be executed because the table has pending changes

I'm getting the following error ..... The search cannot be executed because the table has pending changes that would be lost .... in the following scenario ....
My 1st page is a search page with resulting rows from which the user can select specific rows to process ..... next button will populate the VO for the 2nd page by manually looping thru the selected rows in the VO of the 1st page. Loop logic is in the AM and it calls a method in the VORowImpl that uses setAttributeInternal .... the 2nd page displays the selected rows .....
Pressing the back button of the 2nd page will display the 1st page and if the user tries to do a new search .... the error shows up.
Any suggestions on how to handle this?
Thank you.

It seems to me that you are using the same VO on both the pages. If that is the case try to use separate VO for each page.
And as suggested by Sumit, Never use/ rely on browser back button. Instead put a Back button on the second page through you can handle the event yourself rather than leaving on the mercy of browser.

Hi,
I am getting the following error when executing my query:
Error: Due to a lock, query cannot be executed at the moment
Abort System error in program SAPLRSDRC and form /BIC/ZABC_01
The query has been running fine for the past few months.
Can anyone explain why this error occured and what can I do to avoid this?
Thanks in Advance!!
Regards,
Swapna

Hi Swapna,
make sure that the BW system (e.g. another user, process, ...) does not have currently access to the data e.g. like maintain data. In this case the BW sets a lock so that the current user gets exclusively access to the table.
Check the table if there are any locks on it. Call transaction SU53 and check your table for any locks.
Check this thread, perhaps you will find some more information there:

Error message encore cs5 end action can't execute on the final chapter point

Dvd plays great. Exported it as a mpeg 2-dvd, video only. Audio separate as a .wav. imported video as a timeline, audio as an asset. Video is not transcoded.
But I have a sub menu, with 6 chapter markers. I check the project and I get this: "error message encore cs5 end action can't execute on the final chapter point"
Do I need to make a chapter playlist? Because that gave me a "orphaned playlist" error message.
I selected the last chapter masker and had the end action go to the sub menu.

All users are in the end user group.. I even created a new role/user group that gives users complete read/write access to all end user features. Still no go. I think it is an LDAP issue, but I'm confused because everything else works.

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.
Solved!

In ios6, youtube cannot be played in the background unlike in the ios5. Is there a way round this ? And also is it possible to downgrade back to ios 5.1??

in ios6, youtube cannot be played in the background unlike in the ios5. Is there a way round this ? And also is it possible to downgrade back to ios 5.1??

You cannot downgrade your software. The only way you can downgrade your software is by jailbreaking your device (which can be risky if you dont know what your doing). Remember if you are downgrading by jailbreaking it will void your warranty with Apple - and you could run the risk of disabling your device.
However, im not too sure about the YouTube problem, my only guess is that since it is not an original app that comes with the iOS software.

Is it possible to debug a Job which already executed in the Background.

Hi Friends,
My Z program has a bug when run it in Quality System.
If I run this program in foreground to debug, its giving TIME OUT dump.
If i try to run it in Background and started DEBUG mode using JDBG.
Still one of the table fetch gives TIME OUT dump.
Is there any possibility to DEBUG the already executed job?
Regards,
VIJI

Hi,
If the job is running go to SM50..
Select the process:
In the menu..Program/session -> program -> debugging..
OR
Fix the break points.
2) Create job.
3) Go SM37
4) Select the job and write "jdbg" in command line.
1) Use Transaction SM50. This would give you a view of all the background
processes running in the server.
2) Choose your background process from the list and got to
MENU "Program/Mode"->"Program"->"Debugging".

Macro not executed in the background

Hi all,
I have created a macro to delete the forecast and it is working fine in the foreground, whenever i'm running it in the background, it is not getting executed, no forecast is getting deleted. In the job logs, it is giving the following message:
"No data has been changed; data must not be save".
I have tried with different logics for the macro, all are working fine in the foreground, coming to backgroung, nothing is working.
Please help me out.
Thank you
Regards,
Raj

Hello Raj,
For executing in background, you need to set up the 'DP Background' jobs. You must ensure that you define a proper Selection ID in Interactive Planning and assign this selection ID to the DP background job. If the proper selection data is not picked up by the Macro, then it may not execute. Hope you have followed that process of setting up Background DP jobs correctly.
Also note that when you execute the Macro in background, if data has not been changed, you generally get a message saying 'data not saved'.

How to create hierarchical LOV and CR front end or wrapper report to replace the JSP code in BO4.0?

Hello CR experts ,
My requirement is - There are customer names & region names ,Client wants to go for dynamic cascading prompt and hard code the customer name ,bu t they DON'T WANT customer names to be appear in the cascading dynamic prompt input values (they wants to make customer names as confidential ) ,
Reporting tool Name - Crystal reports ,
Source - UNV
Older versions like BOXIR2 / BOXIR3 they used JSP to achieve this ,it worked fine ,Now they need to do the migration of older CR to new CR reports 2011 ,
In CR 2008 they achieved this through Business Views (Hard coded the customer names in JSP and called it in the CR 2008 ),
SAP BI4.0 won't support BV ,
Could you please help me in detail , how can i achieve it .
Thanks ,
Pradeep Gorpadu

Hi Pradeep,
BI 4.0 still has Business Views and CR 2011/CR 2013 still support them.
CR for Enterprise does not support Business Views though.
Where do you wish to create the functionality? In the Universe or the CR Designer?
If it's the Universe, then is it a .unx or a .unv Universe?
CR 2011/CR 2013 will Not support a .unx Universe; only CR for Enterprise will.
If you're trying to create the prompts at the Universe level, then you've posted the question to the wrong space. You should post to the Semantic layer space.

Front-end memory and limitation cells of the BEX Analyzer

Hi BI experts,
After BW upgrade from BI 7.3 to BI 7.4 some heavy workbooks stopping to work, the error is "Client Out of Memory", the cause of this error is the memory capacity of .NET framework, this process can allocate a maximum of approximately 1.2 gigabytes (GB).
The notes 1040454 and 1411545 says that it´s possible to execute something like 750,000 cells but we made some adjusts and we could increase it until 1,800,000 cells, below some configuration we´ve made:
Query Designer:
Result Rows Always
Supress;
Display as Text or key;
Supress Zeros as Active (All Values = 0) and Effect on rows and columns.
Bex Analyzer:
Display Sort Icons Disable;
Apply formating Disable;
Allow navegation Disable;
We need some orientation how to further increase this limitation, or leaving the query lighter or increasing the memory limitation of .net framework or backing to BEX 3.5 funcionalities.
Has anyone encountered such problems in the update? Some alternative solution ?
Thanks !

Hello Caio,
The limitation lies on .Net Framework 32 bits which can handle 1.2 gigabytes.
You are reaching 1.8 Million because your datacells has no data or almost no data.
There is a KBA documenting your issue: SAP Note 1860872
There you will find a recommendation of Openhub, that allows you to extract data.
Just remember that BEx Analyzer is a tool for query navigation, not mass data extraction.
