Hi BAPI_ENTRYSHEET_CREATE Problem

Hi abapers
we have requirement to call BAPI_ENTRYSHEET_CREATE from JAVA throguh JCO.
but the COMMIT is already writeen by sap inisde ABAP Source code.
but when JCO called BAPI_ENTRYSHEET_CREATE Multiple times java people getting the error messgae as 'USER ALREADY PROCESSING PURCHASE ORDER'.
i know that i can use 'BAPI_TRANSACTION_COMMIT' where WAIT = 'X' for BAPI which doesn't have inside Commit code.
for BAPI_ENTRYSHEET_CREATE already commit is written.
how can i avoid the above error message while calling form JAVA.
thanks & Regards
Ramesh

Hi ramesh,
pass the TESTRUN parameter as 'X' and run.
the
if the return table is empty or is with no errors, then use bapi_transaction_commit.
else use the fm BAPI_TRANSACTION_ROLLBACK.

ravi

Problem with BAPI_ENTRYSHEET_CREATE

Hi Experts,
In my upload program for Service Entry Sheet (ML81N) i am using BAPI_ENTRYSHEET_CREATE.I am reading all the PO related information (like PO, item, quantity, gross price, network, activity etc) from a flat file.Program is successfully creating the Service Entry Sheet, but the problem is that it is not picking the network value from the flat file, instead it is picking network value from the PO.
I am populating the bapi structures as follows:

BAPI_EntrySheet_Create Issue

Hi Experts,
I am using the BAPI_EntrySheet_Create to create a SES without using the service master. I provide the entrysheet header, account assignment and Entryservices information. The BAPI returns with message that SES has been successfully created. But when displaying the SES using ML81N transaction, there is no line information displayed like short text, quantity or gross price.
Please help.
Thanks,

Since it's been a while you wrote I assume this problem was solved.
But if you didn't....:
For calling the service, you must specify the service included in the PO by entering such values as PACKNO and SUBPACKNO. You can find this information in EKPO by entering with EBENL and EBELP, and extracting the value that EKPO-PAKNO gives you. Then go to table ESLL and get SUBPACKNO. Be sure to transfer this information (along with other parameters) to bapi BAPI_ENTRYSHEET_CREATE in a correct way or it'll crash.
Currently we have an issue with this bapi: after getting the service, an endless loop appears and a time-out dump arises.
If nothing works, I'll write a message with more details to call for help.

Assign the network code with BAPI_ENTRYSHEET_CREATE

Hi,
I want to set the NETWORK CODE of the PO to every services that I insert in the entry sheet created with the BAPI_ENTRYSHEET_CREATE.
Now I am able to set the NETWORK CODE only for planned services but not for services that comes from contract linked with the PO in this case the services are inserted in the entry sheet with the WBS code of the contract.
How can I resolve this problem. Is there any parameter that I have to set in the BAPI?
Thanks in advance
Luca

Anyone could answer to my question?
Thanks

Bapi BAPI_ENTRYSHEET_CREATE

Hello,
About this question i found one thread in Abap forum :
BAPI_ENTRYSHEET_CREATE
and i have the same doubt that appears in the end of the thread. Can anyone explain the significance of the import and table field parameters, related to one P.O. with services items. Also, please with the link between the data entered in the bapi, and the EKKO, EKPO and ESLL contents for that purchase order.
I'm trying to use the bapi, but i got the message that there's an error in the register update. The bapi returns one entry sheet number, but it does not exists.
Thanks,
Paulo Sousa

Hi,
The problem is i believe i'm filling the entry parameters well, but i think there's someting missing, reason why i got the error message. In my example i have P.O n. 4500009283 that have in EKPO PACKNO = 16964. In ESLL the entry that have PACKNO = 16964 has SUB_PACKNO = 16965. Also in ESLL with PACKNO = 16965 i have 4 entries, one of them ( with EXT_NUMBER = 0060 ) is the service i want to pass to the entry sheet with Servico code = 4000001, quantity 1 and value 100, 00.
To do that i'm filling the following parameters :
ENTRYSHEETHEADER
PCKG_NO = 0000016964
SHORT_TEXT = TEST
PO_NUMBER = 4500009283
PO_ITEM = 00010
DOC_DATE = 27.12.2006
POST_DATE = 27.12.2006
ACCEPTANCE = X
ENTRYSHEETACCOUNTASSIGNMENT
PCKG_NO = 0000016964
GL_ACCOUNT = 62235000
BUS_AREA = ANA
COSTCENTER = 110400
ENTRYSHEETSERVICES ( 2 entries )
1ST
PCKG_NO = 0000016964
LINE_NO = 0000000001
SUBPCKG_NO = 0000016965
2ND
PCKG_NO = 0000016965
LINE_NO = 0000000002
EXT_LINE = 0000000060 ( the service item i want to enter )
SERVICE = 4000001
QUANTITY = 1,000
BASE_UOM = UN
GR_PRICE = 100,00
ENTRYSHEETSRVACCASSVALUES
PCKG_NO = 0000016965
LINE_NO = 0000000002
QUANTITY = 1,000
NET_VALUE = 100,00
and when i test the bapi with those parameters i got the message 'Error updating register'. I got a entrysheet number in the ENTRYSHEET parameter but that entry sheet number does not exists.
I'll apreciate any sugestion about data that i need to give in the entry parameters/table entries, and that is not being filled at the moment.
Thanks,
Paulo Sousa

BAPI_ENTRYSHEET_CREATE Usage

Hi Friends,
i am using this BAPI ( BAPI_ENTRYSHEET_CREATE) in my code
and for a partcicular scenario return table is filled with the error message
'sum of percentages > 1000.0 < Exceeds 100%'
I am unable to run the bapi due to auth issue for the same scenario .
I tried going through the code of BAPI to search for this message , I tried even checking message class 'SE'.
Is there any smarter way i can find where exactly msg get triggered.
Thanks

BAPI_ENTRYSHEET_CREATE ses Change % allocation - Po Planned account assignm

Objective:
u2022     Create Service Entry Sheet SES using BAPI_ENTRYSHEET_CREATE Transaction ML81N.for Purchase order with multiple account assignments.
u2022     Change the percentage allocation or allocate the quantity to selected accounts when creating the SES. We can do so when we create SES sheets manually.
Problem: BAPI overrides the input. It allocates the amount to all the cost objects.
Sample :
PO account assignment Quantity/Percentage is as 55& and 45 %.
Manually we can enter quantity which is different from the PO Quantity /Percentage.
In the example we are trying to create the SES sheet with the allocation of $10 to first accost object 78003000.
BAPI automatically distributes the amount to both the cost objects based on the POu2019s percentage.
Question: Does BAPI support the above functionality.
           If this is supported.
                Please suggest the sample code of the required entries.
I have read the following oss notes
MM_SRV series notes.
Note 420334 - BAPI_ENTRYSHEET_CREATE: Model for creation
Note 77272 - MM-SRV: Interface for data exchange
Note 452608 - BAPI: Service specifications with outline
BAPI_ENTRY_SHEET_CREATE tutorial by Christian Kleinschroth
Please let me know any other OSS notes which will help.
Thanks

Hi,
Check SAP Note 536835 and 986683.
The function module calls PSPNUM_EXTERN_TO_INTERN_CONV and external number has to be passed to this BAPI.
Hope it helps.

A problem with threads

I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
Thank you in advance,
Lefty

This was one solution from the socket programming forum, have you tried this??
public Thread MyThread extends Thread{
     boolean active = true;
     public void run(){
          ss.setSoTimeout(90);
          while (active){
               try{
                    serverSocket = ss.accept();
               catch (SocketTimeoutException ste){
               // do nothing
     // interrupt thread
     public void deactivate(){
          active = false;
          // you gotta sleep for a time longer than the
          // accept() timeout to make sure that timeout is finished.
          try{

You can also try to provide a greater Priority to your player thread so that it gains the CPU time when ever it needs it and don't harm the playback.
However a loop in a Thread and that to an infinite loop is one kind of very bad programming, 'cuz the loop eats up most of your CPU time which in turn adds up more delays of the execution of other tasks (just as in your case it is the playback). By witting codes bit efficiently and planning out the architectural execution flow of the app before start writing the code helps solve these kind of issues.
You can go through [this simple tutorial|http://oreilly.com/catalog/expjava/excerpt/index.html] about Basics of Java and Threads to know more about threads.

N.B. And yes there are more articles and tutorials available but much of them targets the Java SE / EE, but if you want to read them here is [another great one straight from SUN|http://java.sun.com/docs/books/tutorial/essential/concurrency/index.html] .

J2ME problem with threads

Hi all,
I would like to ask you for a help. I need to write a small program at my university. I started to write a midlet which function would be to countdown time for sports activities. I woul like to start a new thread - the one that counts down - and at the same time make the main thread sleep. After the "countdown" thread finishes, the main thread wakes up and waits for user input. The problem is that when the "countdown" thread finishes his work, I've got Uncaught exception java/lang/NullPointerException. error and the midlet halts.
Below you can find the code

}Can anybody help me with this?

Groovemaker,
Your Licznik class has a member m of type monitor, which has not been instantiated (in other words is null) hence, when calling m.put() you get NullPointerException. Please also mind, that using Thread.sleep(1000) is not an accurate way of measuring time.
If I may, please use recommended for Java class naming conventions - some of your names use lower case, while other don't which is confusing to the reader.

Problem with threads within applet

Hello,
I got an applet, inside this applet I have a singleton, inside this singleton I have a thread.
this thread is running in endless loop.
he is doing something and go to sleep on and on.
the problem is,
when I refresh my IE6 browser I see more than 1 thread.
for debug matter, I did the following things:
inside the thread, sysout every time he goes to sleep.
sysout in the singleton constructor.
sysout in the singleton destructor.
the output goes like this:
when refresh the page, the singleton constructor loading but not every refresh, sometimes I see the constructor output and sometimes I dont.
The thread inside the singleton is giving me the same output, sometime I see more than one thread at a time and sometimes I dont.
The destructor never works (no output there).
I don't understand what is going on.
someone can please shed some light?
thanks.
btw. I am working with JRE 1.1
this is very old and big applet and I can't convert it to something new.

Ooops. sorry!
I did.
     public void start() {
     public void stop() {
     public void destroy() {
          try {
               resetAll();
               Configuration.closeConnection();
               QuoteItem.closeConnection();
          } finally {
               try {
                    super.finalize();
               } catch (Throwable e) {
                    e.printStackTrace();
     }
