Synchronized void dopost() Not Possible???

Hi,
Why we can't do
public synchronized void dopost(){
as supposed to :-
public void doPost() {
synchronized(this) {
Ofcourse both of them allows only one request or only one thread to access the method at the time. Then why the former one is not possible
that is synchronized meth??
Thanks,
JavaCrazyLover

In the first example, you don't attempt to read the response from the servlet. At least I don't see where you do that. So the request never gets sent.

System Error- Restart Not Possible

Hi All,
I have Synchronous scenario.
I am trying to handle system error in BPM. so if system error comes i m cancelling process.
So in sxmb_moni, my scenario is successful as it is not getting stuck into queue.
But it is giving me error as "System Error - restart not possible" .
But I need to resend / restart this message again.
So can u please guide me for same
Regards,
Manisha

When your WS id down you are handling the esception in your BPM perfectly....what more you can do is in the exception branch throw an alert to the support team from SAP saying that the processing for a particluar IDOC failed as there was an error while connecting to the end system......in this case you can ask them to restart this particular process once the WS is up....
One option wil also be to increase the default retry attempts of AE while connecting to the end system....affects performance....maximum retry attempts is 10 (if i am not wrong).....so if your WS comes up during this time you can send the message......
We have a similar case wherein same logic has been applied in BPM...which asks the support team to restart the process if the process fails due to a communication error with the end system.

Abhishek.

BPM SMQ2 in sysfail Access using a 'ZERO' object reference is not possible

Hi ,
I am working on a IDOC to SOAP synchronous scenario
So I am using a BPM....
I have written a operation mapping outside BPM
1) Request MM creates the SOAP rquest
2) Response is a ABAP mapping where i am checking the response from webserice and then generating an email using ABAP code.
now when i am running this scneario works fine and the mail gets generated...
however i get a green flag in moni and in SMQ2 in sysfail Access using a 'ZERO' object reference is not possible
PS : Also the response coming from the webserice has a custom header which does not match with the response ABAP mapping source MT
however if I work on the same thing using Proxy to SOAP sync there is no sysfail message and it works fine
Is this a bug in the system ...i am using PI 7.1

Hi,
Try to implement SAP note 1164228 or apply package SAPKB71007 to resolve your issue.

Restart not possible (Xml message)

Hi All,
I am facing the following error in SXMB_MONI , restart is not possible & unable to check the payload.
can any one please let me know what is the cause for it & how to resolve it.

Message Status is System Error RESTART NOT POSSIBLE(RED colour Round Button)

Have you configured Receiver Determination with the appropriate target system and interfaces? Looks like your target system is down or connectivity errror...
Go to SXMB_MONI and pick that message and navigate pipeline steps and see where it fails.. Also the steps it fails you check the payload or response mesg and you will see the details of error.
Also go to RWB and check your communication channel monitoring area. See any help you get.
Also go to RWB and go to message monitoring. See the inbound side of the interface and see what is the reason for the error.. Sometime if the receiver comm channel or target system has issue you mesg stop.
Check SMQ1 and SMQ2 and see any locks for those mesgs. If so remove locks and activate again.

Synchronized keyword was not supposed to be reentrant ?

Synchronized block in the below code seems to be working properly as a reentrant code. I've written this to check out the reentrancy by causing a deadlock but it worked without deadlock./* This code might cause to a deadlock */
public class NotReentrant {
     public static void main(String[] args) {
          final LoggingWidget widget = new LoggingWidget();
          Thread t1 = new Thread(new Runnable() {
               public void run() { widget.execute(); }
          t1.start();
          try { t1.join(); } catch (Exception e) {}
          System.out.println("You might not going to see this: There is a deadlock !");
/* dummy classes that show the proof */
class Widget {
     public synchronized void execute() {
          System.out.println(toString() + " (base).execute: synchronized");
          synchronized (this) {
               System.out.println(toString() + " (base).execute: synchronized (this)");
               try { Thread.sleep(500); } catch (Exception e) {}
               System.out.println(toString() + " (base).execute");
               // .... code
class LoggingWidget extends Widget {
     public synchronized void execute() {
          System.out.println(toString() + ".execute: synchronized");
          super.execute();
          System.out.println(toString() + ".execute");
}

I perfectly understand how Java monitors work and I also perfectly know that Java synchronized ( aka intrinsic locks ) monitor is re-entrant.
The reason behind my previous post was that I am trying to check out a code which is written in Goetz's book: Java Concurreny in Practice. In there, he gives a code example that leads to a deadlock. Despite, I am aware of the fact that it cannot be occurred, I have given it a shot.
Thanks for the comments.

Load file synchron? Is it possible?

Hi,
i have a program, and this program need some data from a
file. If i use URLLoader it's load asynchron, but i need that my
program "wait" until the config file loaded. Is it possible somehow
to load this file synchron,
something like (program lifecycle)
1. Program does something
2. Load file
3. Results from the file
4. Program does something
This asynchron it look's like
1. Program does something
2. Load file
3. Program does something
10 Program receive the result from the file.

Hi yevgen_78,
It is not possible to load the file synchron. The best way I
think is to leave the program in a "loading" state until the call
back for loading event result gets called.

Can it not possible that i can retrive it for all line items in a single qu

I have to make report for my application in which I am facing a following problem:
In the application there are multiple suppliers and each supplier having multiple line items and each item having multipale events. each evant having three status GREEN,RED and BLUE.
When a user select 'all suppliers' to show the the status time span for a supplier (i.e. for a supplier how many parts and upto how much time parts are in blue, red and green status)
to show the cumulative status time span I have to find out a event for each line item which is having nearest lower entry time from the lower part of the given time span.for this i have write following query
SELECT * FROM parts_events
WHERE vendorid = ? AND partid = ?
AND visible = 'visible' AND active = 1
AND entrytime = (SELECT MAX(entrytime) as
entrytime from parts_events
WHERE vendorid = ?
AND partid = ?
AND entrytime < ?
AND visible = 'visible'
AND active = 1)
the problem is that i have to fire this query for each line item, can it not possible that i can retrive it for all line items in a single query?

maybe if you can post some sample data and output will help us analyze more youre requirement.

Transaction type 100 not possible (posting to affiliated company)

Hi All SAP Guru's
I am trying to post asset acquisition through F-90
Asset Dr Transcation Type 100
To, Vendor Cr
while saving the above document i am getting an error Transcation type 100 is not possible (Posting to Affiliated Company)
to explain further my client are using Trading Partner Concept, may be that is the reason document is not getting posted
In Transcation Type I tried to change Post to affiliated Company then system allowing to post the document, but in real sense we should not give post to affiliated company at Transcation Type
can anybody help, is there any alternative to go ahead
Regards
Sreenivasulu
Edited by: sreenivasulu VAS on Feb 26, 2009 1:57 PM

Hi,
When there's a trading partner in the document, you need to use a different transaction type for external acquisition.
Have you tried this? (I've used this one. without chaging document type setting)
150 Acquisition from an affiliated company
Difference from Transaction type 100 is posting type. 150 has a posting type of 'Post to affiliated company' whereas 100 has not.
Check with IMG (T-code: AO73)

Transaction type ZGC not possible (posting to affiliated company) in ABSO

Hi all,
We have depreciation areas 01, 30, 31, 32 .
dep area 30, 31, 32 inherits the values from 01.
We want to post credit value to dep area 01 after doing the aqusition .
Hence we created a seperate transaction type ZGC ( in aqusitions- Tcode AO73) and limited it to dep areas 01, 30, 31, 32.
Transaction type ZGC is having credit and " do not post to affliated company " radio button is selected.
Now the issue is when we run ABSO to do a credit post in dep area 01 we are getting the below error .
Transaction type ZGC not possible (posting to affiliated company)
Message no. AA390
Diagnosis
For the current document, you specified either implicitly (via the customer/vendor), or explicitly (with a manual entry), that this posting is to an affiliated company. In this case, Asset Accounting requires you to use special transaction types. This enables the system to separately identify such transactions.
Procedure
Check the line items that you have already entered, and the transaction type you entered.
Not sure why it is asking for affliated company .
It will be great if any one help on this why we are getting this issue.

Hi Daya,
Please try to choose Trans.Type 100 in AO73 transaction code and select the radio button Post to affiliated company under Posting type.
Thanks,
Kumar

Error while creating source system in BI: Modification not possible

Hi All,
We are about to move to production, and therefore it's necessary to create in BI the source system related to our ECC (R/3). While trying to perform this action from BI side we received the error message:
SAP system has status 'not modifiable'. Because of this, and following with known consultants practices we've changed the client to customazing but it still not working although the message at this time is: Changes to repository or cross-client Customazing are not permitted. We have also verified transaction SE06 but it's not possible to change the Cross-Application Component to Modifiable.
Did someone face with this same problem before?
Thanks to all in advance,
Regards,
José.-

Hi Rick,
I really appreciate your quick response. We followed your recommendation and could create the source system without problems. Thanks once again!
Best Regards,

Creation of new DC is not possible

Hello,
I'm working with Visual Composer on a CE 7.1 SP05 that is not currently configured to work with a DI server. I have a development component "mydc" in the shared repository that contains some models.
Whenever I want to create a new model in the shared repository, the system forces me to use the existing DC "mydc". The listbox for the development component offers only the value "mydc" and the button "New..." is inactive.
(When I create a model in the local repository, the "New..." button next to the DC listbox is active and I can create a new local DC.)
Please help me create a new DC in the shared repository.
Thanks and cheers,
Thorsten
Edited by: Thorsten Franz on Apr 16, 2008 6:27 PM to remove question on how to delete a DC in the shared repository - it's not possible in release 7.1.

Hi Thorsten,
To creat a new DC in shared repository do the following:
1. Create a DC in the local repository
2. Go to manage models, click on the newly created DC and you would see the icon with blue + (tooltip: Add to the source control)
3. Your local DC is now your shared DC
Good Luck,
Dharmi

Not possible to output CFTREEITEM in a CFC function?

Hi there,
I am parsing a sorted list of strings (in the form of a/b/c/,
a/b/c, /a/c/d etc.) and trying to make a treeview out of it.
I have the CFFORM and CFTREE tag in the top function and the
code that generate CFTREEITEM in a subfunction, but I got the
following error:
Context validation error for tag cftreeitem.
The tag must be nested inside a cftree tag.
It seems that ColdFusion doesn't recognize that calling code
is already nested inside a CFTREE tag in the top function. I
extract the code generating CFTREEITEMs to a sub function because
it is called multiple times from different context, it would be a
lot of hassle and quite stupid to "inline" it.
If what I am trying is, for whatever reason, not possible,
would it be possible then to have the sub function generate the
code into a string and somehow dynamically evaluate that?
Any hints or tips will be greatly appreciated!
Billy

Hi,
SAP doesn't allow you to reverse a document in FI if it was created subsequently from another module (in your case HR).
Why don't you use F-44 transaction code to manually clear the open vendor line item and offset it against the same clearing account?

- Read Knowledgebase article # 954322.1 - the suggested things in there don't seem to apply to my case, unless I am missing something.
At this point does anybody have any suggestions ?

An update: Just for kicks, I tried restarting Essbase using Start->Programs-EPMSystem->Essbase->EssbaseServer->Essbase.bat and apparently now Essbase is started.

This is really strange. There is NOTHING that I changed, started or stopped which could have caused Essbase to start magically all of a sudden.
Any insights into the cause of all this ?
