RHINTE20 and background processing

Does anyone know how to set a variant when running RHINTE20?
When I run the program it presents a list of objects to be corrected, and I manually select all the subtree with the icon and then run Create Several Objects. It's these last two steps I'd like to specify in the variant, so I can setup the job to run nightly (grab the folders and process all objects).
Thank you in advance for any hints to resolve this.
Cheers, Al Perkins

Hi Albert,
Make all your selections and click on Save (CtrlS). You will be taken to Variant Attributes screen. Give the variant name, meaning, check "only for background processing" and save. Then when you execute the program, you should be able to select your saved variant by clicking on Get Variant (ShiftF5).

ABAP trail 7.00 timeouts and background process

Does anyone knows if it's possible to change the number of dialog and background processes?
And the transaction to change the timeouts of such processes?
Thank you

you can change the timeout in rz11.Parameter-name is rdisp/max_wprun_time. Backgound processes habe no timeout, so this value is only valid for dia-processes
To change the number, you have to adjust your instance profile. In the forum 'Netweaver Administrator' should be some information about that. So just the short hint: you can adjust the profiles in RZ10, but have to do some steps for that. Just search in NW-Admin-forum above.

GUI_DOWNLOAD and background processing

Hello,
I have created a process which creates a file. this process uses GUI_DOWNLOAD to put the file on the users C drive or other directory on our network. The user wants to run this process in background and the program is returning a 6 (error unknown) from the GUI_DOWNLOAD FM. I was looking on SDN and found out the GUI_DOWNLOAD only works in foreground. You have to use OPEN and CLOSE DATASET statements to process in background. I am thinking about putting a button to denote foreground/background processing and using the appropriate statements to process the file. I will then have to get the file from the app server to a place will the user can get access to it.
<b>first question</b> - is there a FM to do a FTP from the app server to a directory on our network for the user to access?
<b>second question</b> - is this the right approach or is there something else that I should be doing.
thanks in advance for your help

Hi,
Yes, your right, GUI_DOWNLOAD wil not work in background mode, you need to place the file in Application server, here.
See the below link for a FTP program, use the proper commands(i do not know whether downloading the file is possible through the commands)
http://www.sap-img.com/ab003.htm
or else, write a small program which downloads the data from the application server, but it should run in the foreground

How to deploy an app with servlet and background processing

i have a servlet with background processing. it has to run 24 hours a day.
but i have problem with shutdown (after 1-2 hours without user action). [9iAS 9.0.3.0, windows 2000]
i created for application seperate OC4J (in the EM) and i deployed it there. first time as war file, later as ear file (because there is possible to re-deploy only ear file).
but it seems that the servlets are not designated to run as a uninterruptible task.
the question is: how to deploy such (servlet + uninterruptible background processing) application in the 9iAS?
a) everything in the OC4J (then how to disable shutdown?)
b) servlet in the OC4J. where (and how) to install the rest of application?
b1) servlet in the OC4J + rmi/soap/... + standalone server?
what is the standard in the oracle world :) ?
thanks

Difference in Foreground and Background processing of an object

we have implemented SAP ECC 6 on May 6th, 2008.
We are facing an issue in a BDC order creation program when run in background.
But when the same program is executed in foreground it works fine.
In issue is one of the customized condition ZFML is not getting calculated at all.
This customized condition gets determined in an user exit MV45AFZZ in FORM USEREXIT_FIELD_MODIFICATION.
Value gets calculated correctely for the conditon ZFML while executed the program in foreground but it fails in background.
The obove exit is being processed when I'm executing a BDC for creating Sales Order through the text file from application server for multiple line item. This needs to be executed every one hour through background only
When I run the BDC in foreground, It is properly executed, but in the background it is not for one particular pricing condition, which is a customized pricing for freight to determine whether for all entire order or for the each line item. System does correctly for the entire order, but not for each line item.
Is it possible that the userexit is not getting triggered in Background.
I had never encountered such situations before. I'm not able to predict this peculiar behaviour of BDC.
Any solution.

Stuck with Foreground and Background processing in Workflow

Hi All,
I have a BDC that is acting as a method in the Business Object. The requirement is something like this: The scenario is in the Utilities System. When a customer pays a security deposit a PM (Plant Maintanence) Service Order has to get created automatically in the background. I have a BDC for creating the Service Order but the thing is that if I make that task which runs the BDC as foreground and give the agent assignment it works absolutely fine and the service order gets generated, but if I make the same task as background the Service Order does not get created. I am heavily stuck with this issue.
Has anybody encountered the same issue ?
Best Regards,
Sudhi

Sudhindra,
Are you checking for errors after the BDC Call Transaction? What I normally do is to use the Messages into option of the BDC call and return the messages to the Task Container in case of errors.
Reasons why the method does not work in background is possibly due to authorizations or the WF-BATCH user being not known to the PM system. For instance when I create PM notifications in WF in background, I have to translate the WF initiator's user id to their Personnel Number for the Resp. Person field. If in your workflow the prior step to creating order is a dialog step, you can also try the Advance with dialog option on the background step.

Ramki Maley.

Differentiate foreground and background processing

Hi All,
I want to execute a certain report in background. If the user tries to execute the program in foreground, the system should prompt him not to run it in foreground. In the same way, the message should not come if the program is run in backgroud.
That is, the system should differentiate whether the program is run in foreground or in background. How to differentiate them?
If i could differentiate, i could code a message to display when the user runs the program in foreground.
Please help me.

if sy-batch = 'X' '' then it is runing in background other wise it is running in foreground
<enter ur code here, to display when running in background>
else
<enter ur code here, to display when running in foreground>
endif.

Dialog process vs Background process

Hi,
What is the difference between dialog and background process?
Can a dialog process is used in a process chain?
Does an ABAP program followed by change run be a dialog process or background process in a process chain?
What is the standard maximum runtime duration of a dialog process?
Regards,
Pradeep

Hi,
Dialog Process - Executes dialog programs (ABAP)
Background Process - Executes time-dependent or event-controlled background jobs.
All the Processes in Process Chain will be Scheduled in Background.
and The Maximum workprocess Time will be defined by BASIS Team.

Background Processing, Selection Screens and Variants

Hi All,
I am having a little trouble Background Processing with Selection Screens and Variants.
When a user runs my report and selects the option of background processing, then they select a checkbox. Once this is checked, they should go and fill in details, press Execute and voila a background process is created. However what is happening is that when i execute it then it asks for a variant. I do not want this to happen. I want the values in the selection screens to be used as default. Here is my code for background processing

Experience in ABAP OO and heavy background processing?

Hi,
we're planning to develop a new application with a (very) high part of background processing. We plan to use the ABAP OO. We also want to make a good OO-Design (with many SETTER and GETTER methods and so on). I'm afraid we will get a lot of "program to program" communication and we will atomize our application. Also it's sounds to me like a conflict with the stuff from the Performance-course BC490.
Has anybody experience with ABAP 00 and applications that normally designed for a "number cruncher"?
Thanks and regards,
Stefan

Hi Mariana,
I've started with two technical prototypes that have a very little business logic. One prototype is designed in the "good old" ABAP and one in the ABAP OO and a selfmade OO-framework from our company. This framework is very comforable and offers a lot of methods and superclasses. For vectors there is a own superclass. So for you question: We use a own object to pass the vectors.
Also we use the software objectif for the OOD. I've learned how important a good OOD is, before I started any coding.
My prototypes have a very simple business logic. They creates bills for 10.000 invoice recipient. The only feature is, that every recipient can have his own customizing to decide which items should be together on one invoice to a individual invoice date.
I must admit that the API in the OO prototype are more understandable, but for the performance I see still the follow bottlenecks with the I/O:
- When I instance a business object, all attributs are loaded into the memory. In the old ABAP I use only the required fields. So the "smelly" SELECT *-Statement is back again...
- A business-class (A) that have dependent business-classes (B1, B2, B3...BN) should instance his dependes objects with the first access the the class (A). When the classes (B1,B2...BN) has also dependent classes, this object should be instances (B1 has C1,C2,C3..CN), too. There is always a "vector"-class between this classes that notice the reference of his objects.In my prototype for example you have a invoice recipient.
In my prototype for example I have a class invoice recipient (class A). This recipient has a vector of bill-header (class B) and every bill-header has a vector of bill-items (class C). Between every of this classe is a vector-class that manage the references of the objects.
I've programmed this lazy (hope that this is the correct word that a OO-gurus use). This means I instance only the class A. If there is a call to a method from object A that need the information from the class B-objects, than i look if the reference of the vector-class for the B-Object is already available. When not I instance the vecotr-class and this reads all dependens object B.
So there is much more I/O than in old ABAP, after all.
However I'm a OO beginner.
Therefore I'm waiting that an OO-expert from our company take a look to my prototype coding and improve this for a better performance. I'm looking forward for some good tips. I will let you know when I've good some other nuts and bolts.
Perhaps SAP needs a OO-database instead a rational database, so that all GET-methods goes directly to the database to avoid a instance with all attributs in the memory of the application-server...
Many greetings from germany,
Stefan

AQ Callbacks - Blocking background processes and best practices.

We are running several queues within our company and one of them uses pl/sql callback functionnality.
Basically, several triggers can enqueue a message when underlying tables are updated. The goal of the callback is to "treat" those messages, which means dequeuing the messages and passing them to some procedure (determined through a confguration table and the type of message). I don't know if i'm clear enough on this but it is as important.
In general the mechanism works perfectly but we noticed in one of our databases that, after a relatively big amount of messages enqueuing (~ 500-1000 in one trasanction), there are numerous background processes blocked on system table SYS.AQ_SRVNTFN_TABLEI. In fact, the queue starts growing and messages are not dequeued anymore by the callback, that doesn't seem to be executed anymore at all.
We actually were also unable to re-compile the package that holds the callback procedure nor removing/adding the reference of the subscriber to the queue with DBMS_AQ. It would hang there forever...
We are running Oracle Database 10g Enterprise Edition Release *10.2.0.4.0* and the value of AQ_TM_PROCESSES = 0.
I don't necesseraly have a complete and clear view of how the queue mechanism works behind the scenes so forgive for some foolish things I could say :-)
Diagnosis:
After some research, it seems the backgrounds processes are blocked on the system table SYS.AQ_SRVNTFN_TABLE on some index for MSGID.
If I understand correctly how the system works, the callback gets executed for a specific MSGID as we use it in the callback procedure to dequeue this message.
I've also discovered that the default value for the WAIT dequeue option is FOREVER...
So my idea was that, for some reason, the callback tries to dequeue a message that does not exist in the queue and... waits forever for the message to "appear".
This at first seemed pretty unlikely to me: why would the callback be executed if no message with provided MSGID exists... then you start doubting :-)
Attempt to resolve:
We've decided to alter the WAIT option to not let the dequeue in the callback wait forever.
We have made some tests (outside the callback) with NO_WAIT and also with a wait of a few seconds. Both solution prooved right so we added a wait of 60s in the callback and added some tracing.
Since then, no more background processes seems to hang there and we are able to alter the callback procedure normally. But with the added tracing, we noticed an unexplained behavior with the execution of the callback:
- callback runs
- ORA-25263: no message in queue QUEUE_OWNER.MULTISRC_NOTIFQ with message ID B4FFD1115523A46EE040007F0100304F
- callback runs again and message is dequeued and treated correctly
The first oracle error happens fast, not after 60s as the WAIT option specifies.
Questions:
<li>Is the way the callback method is implemented correct (see code below) ?</li>
<li>Do we need to commit in the callback method ? What implies committing or not ?</li>
<li>How wouold you explain the behavior of the callback after setting the dequeue WAIT to 60s and why it does not actually wait for 60s ?</li>

Helping you with the specific issue is going to be difficult without direct access to the servers but given the importance this system seems to have to your business why are you not running on a fully supported version (10.2 has been in extended support for more than 6 months) and even in the current configuration not patched to 10.2.0.5?
My instinct would be to focus on moving to 11.2.0.3 as quickly as possible with a corresponding change to a current operating system version if your O/S is similarly out of date.

Create and Format an Excel File as a Background Process(Application Server)

Hi all,
I have a requirement to Output a formatted(Bold fonts, Merged Cells etc.) Excel File.
It is to be run as background process. So ideally, the file will be produced in the ApplicationServer and will already contain the formatting. If I am to use ole2 functions such as
*--Opening the existing document
call method of gs_wbooks 'Open' = gs_wbook
exporting #1 = file_path.
Is this possible? can file_path point to the file created in the ApplicationServer?
Any answers, suggestions or workarounds would be greatly appreciated.
Thanks in Advance

no.
that works only in dialog

Clarification of background processing and BAPI_DOCUMENT_CREATE2

Hello,
i am sorry to mention this long discussed topic,
but i would very appreciate to clarify how can i checkin new originals for a new document using background processing.
we are trying to use BAPI_DOCUMENT_CREATE2 to create a document and checkin original from a network path +
server\file.pdf+ .
i have read that i should add the path in AL11 - did it, how should i use it?
i have read that i should use the SAPFTPA & SAPHTTPA parameters when calling the function - i have these in SM59 and the connection test is successful - but what should i do with them?
will be very thankful for your help.
here's an example from our code:
call function 'BAPI_DOCUMENT_CREATE2'
    exporting
      documentdata         = ls_doc
     pf_ftp_dest          = 'SAPFTPA'
     pf_http_dest         = 'SAPHTTPA'
    importing
      documenttype         = lf_doctype
      documentnumber       = lf_docnumber
      documentpart         = lf_docpart
      documentversion      = lf_docversion
      return               = ls_return
    tables
      documentdescriptions = lt_drat
      objectlinks          = lt_drad
      documentfiles        = lt_files.

Hi,
Populate the document original information according as per below guideline.
The tables 'DOCUMENTFILES' contain the entries about originals that you you want to allocate to the document. The meanings of the structure fields are:
'SOURCEDATACARRIER': Data carrier name (optional) of a server on which
                     an original is stored
'STORAGECATEGORY':   Name of the data carrier that you want to check
                     original into. The function module determines the
                     storage type, SAP Database, vault, or archive
                     using the name of the data carrier.
'DOCFILE':           File name of the original
'WSAPPLICATION':     Name of the workstation application. This entry is
                     necessary when no workstation application has been
                     assigned to the document info record or the new
                     original is of another type.

Launch background process from unix command line and detect if it is runnin

in Cocoa, I am able to run unix app by using NSTask, it works fine to me. But I want to do the following:
1. Start up a background process.
2. Wait to see if this background process has been launched correctly.
3. If yes, keep running following codes...
With NSTask, I cannot make sure when the background process has been launched correctly... and other codes just keep running...
If I do something like:
while (bgprocess isRunning)
}

What exactly do you mean by "launched correctly"? Do you just care that the process has begun? Do you want to make sure it is still running? Do you want to see if there is some signal emitted (either affirmative "I am running" or absence of a child-died signal)?
Your isRunning example does appear to be in accord with the NSTask docs for "do blah blah blah while the task is running", but that doesn't seem to be what your description says you want to do. Is "blah blah blah" an idle loop until the task has started, or is it something to do while the task is actually running?
How about looking up the pid of the child process (processIdentifier for the NSTask) and then check whether that process is still running?
