Alternative Block Problems

Hi
I have created a process which contains an alternative block. Inside this block there are two sequential blocks which should be entered depending on the result of a decision action. It looks like this:
1. Alternative Block:
1. 1. Decision Action
1. 2. 1 Callable Object 0
1. 2. Sequential Block 1
1. 2. 1.Action 1
1. 2. 1. 1. Callable Object 1
1. 3. Sequential Block 2
1. 3. 1. Action 2
1. 3. 1. 1. Callable Object 2
Ok, I did everything as described here: https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/4848c8d1-0c01-0010-33b9-87a6488c48a7
Sequential Block 1 should be called, if the result of Callable Object 0 is true and Sequential Block 2 should be called if it is false. Very simple, isn't it? In fact it is not working. At first, it seems if the process worked correctly as it skips Sequential Block 1 if the result is false. But then, it the result is true, BOTH blocks are entered, at first Block 1 and then Block 2.
It would be really really nice and there will be lots of points if you could help me!!
Thanks a lot in advance.
Best regards
Bettina Hepp

Hi Dipankar and Sumangala,
thank you very much for your quick response. Yes, I have set one resultstate target to Sequential Block 1 and the other one to Sequential Block 2:
1. Alternative Block:
1. 1. Decision Action
1. 2. 1 Callable Object 0
Result State true-----target Sequential Block 1
Result State false----target Sequential Block 2
1. 2. Sequential Block 1
1. 2. 1.Action 1
1. 2. 1. 1. Callable Object 1
1. 3. Sequential Block 2
1. 3. 1. Action 2
1. 3. 1. 1. Callable Object 2
In fact, if the result state of the decision action is false, everything works fine, as Sequential Block 1 is skipped. But if it is true, both blocks are entered, at first Block 1 and then Block 2.
Do I need to set anything else?
Thank you very much for helping me.
Best regards
Bettina Hepp

Number of data block problem

number of data block
is there any limit for the number of datablocks in a form?
i have a form that has 8 blocks and all of them are none base,
some times when i use this form it suddenly closed and a special file (ifrun60_dump file)
is created.i donot know the reson and i cannot solve the problem
if you have any idea about this ,plz help me?
thanks in advance.
regards ,
shoja.

Restriction on the number of objects is documented in the Help topic "Limits" - There is no practical limit to the number of blocks in a form. Certainly 8 is a timy number compared with mosdt forms.
Contact support and supply them with the dump file, that should help to identify the issue you have.

MT100 Header Blocks problem

Hello expert,
I have a problem in MT100 generation.
File is generated with the correct payment information but I don't have headr block i mean tags 01, 02, 03, 04, 05, 06 and 07.
There is an option that i should set to print also header block?
Thank you in advance.

Thank you Gaurav.
I checked all MF of all events. There is no tags 1,2..7. In the event 30, the MF creates tags 20 until 72.
The bank sent me the file format MT100 expected. There are two blocks: header Block (Tag from 1 to 7) and payment information block (Tag from 20 to 72). I have no problem with the payment block is what generate SAP and i found those tags in event 30.
by cons I do not know how to enable the generation of header block?
1- This block could be generated by standard SAP ? What i must to set?
2- Or i must use MF to add myself this header block? (Specific dev)
Just for information, header block is like that:
:01: Refrence    --> YYMMDDNN when NN is the file number --> Mandatory for the bank
:02: Total amount                                                                      --> Mandatory for the bank
:03: No orders                                                                          --> Mandatory for the bank
:04: Paying Bank --> SWIFT                                                     --> Mandatory for the bank
:05: Ordering party --> Ordering party name and adress       --> Mandatory for the bank
:06: User No --> User No at the paying bank                         -->optional
:07: File name                                                                         -->optional
Thank you very much for your help.

JOptionPane event blocking problem

Hi,
JOptionPane is causing me a problem.
I have a simple frame that contains a text field and a button.
Pressing the button should write something to the standard output.
When the text field loses focus a JOptionPane in poped to the user.
The following scenario is problematic:
1. The text field owns the focus.
2. The user presses the button.
Expected result:
The JOptionPane appears due to the lost focus event on the text field.
After closing it some text is written to the standard output due to the action event on the button.
The actual result:
The JOptionPane does appears but after closing it nothing is written to the standard output. The button stays in a curious state (when the mouse hovers over the button the button looks pressed, and when the mouse doesn't hover over the button the button looks unpressed).
Probable reason for this behaviour:
The JOptionPane blocks all awt/swing events while it is opened. Some of the button code is perfomed due to the button press, but the ActionListener's actionPerformed method is not invoked.
I need the actionPerfomed method to be invoked.
Can anyone help me?
Here is the source code:
package test;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.text.*;
import java.awt.*;
import java.awt.event.*;
public class Test {
public Test() {
public static void main(String[] args) {
//Test test1 = new Test();
final JFrame f = new JFrame("Test");
JButton b = new JButton("Click Here");
JTextField tField = new JTextField("Text", 10);
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
b.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("Button pressed!");
tField.addFocusListener(new FocusAdapter() {
public void focusLost(FocusEvent e) {
if (e.isTemporary()) return;
JOptionPane.showMessageDialog(f,
"Focus lost",
"Title",
JOptionPane.INFORMATION_MESSAGE);
JPanel content = (JPanel)f.getContentPane();
content.setLayout(new BoxLayout(content, BoxLayout.X_AXIS));
content.add(tField);
content.add(Box.createHorizontalStrut(5));
content.add(b);
f.pack();
f.show();
Thanks,
Shai

Hello Shai.
The JOptionPane seems to consume all events when its shown. (Check the stack after JOptionPane is shown.) I've solved a similar problem with the SwingUtilities.invokeLater() method. Maybe the following example will help:
Runnable doDlgError = new Runnable() {
public void run() {
JOptionPane.showMessageDialog(this, "Error", "Error",
JOptionPane.ERROR_MESSAGE);
SwingUtilities.invokeLater(doDlgError);

GP - Sequential Block Problem with input structure

Hi all
My scenario is as follows:
I have three Actions A1 , A2, A3
every action has collable object of type WebDynproComponent : CO1 CO2 CO3
CO1 has only output parameters that i have mapped to input parameters of CO2 .
Output parameters of CO2 are apped to input parameters of CO3 .
I have created sequential block with Actions A1 , A2, A3.where target of A1 is A2 and that of A2 is A3
I have created IVIEW of this GP process .
when i open iview , ideally it should directly open the webdynpro comp of collable object CO1.
*But my problem is its before instantiation asking me to fill values for input parameters of CO2 which is in sequence to CO1.*
*Is there any setting that i have missed while creating block?*
Regards,
Sheetal

Hi,
If you expose parameters at the process level, it will ask you to provide values while instaniation.
If it is not a mandatory parameter, you can proceed with out providing values.
The best way is don't expose paramters, if is not required at process level.
You have to expose a parameter at process level, only if you want to use that parameter in other processes.
by default, it will be exposed. You have to uncheck it, If you don't want to expose it.
thanks

Thread Problem - (Thread Blocking Problems?)

Hi Friends
In my program while using thread i found a problem in this code .
In this whlie running the 'msg' was printen only after all 5 inputs are given .
why i was not getting output after one input.why the thread out was waiting for remaining threads input.
my code is
import java.io.*;
class MyThread extends Thread
BufferedReader bin;
   MyThread()
     super();
     start();
   public void run()
      try
       bin=new BufferedReader(new InputStreamReader(System.in));
       String msg=bin.readLine();
       System.out.println(msg);
      catch(IOException e)
         System.out.println(e);
public class Threads
     public static void main(String args[])
          for(int i=0;i<5;i++)
            new MyThread();
}

Hi Friends
In my program while using thread i found a problem
em in this code .
In this whlie running the 'msg' was printen only
after all 5 inputs are given .
why i was not getting output after one input.why
hy the thread out was waiting for remaining threads
input.Probably because of how the scheduler was rotating among the threads while waiting for input and queueing up output.
When you call readLine, that thread blocks until a line is available. So it probably goes to the next thread's readLine, and so on. All threads are probably blocked waiting for input before you enter a single character.
Something inside the VM has to coordinate the interaction with the console, and between that and your threads, the out stuff just doesn't get a chance to display right away.
In general, you can't predict the order of execution of separate threads.

Invoice Block problem in MIRO

Hi Friends,
I am facing a issue. Can some one help to overcome this issue please
1. We have created PO with item value Rs 100 and GR is not done yet.
2. Then we created Invoice for value Rs 20. Invoice got blocked due to Quantity (because GR is not done)
3. Now,I am creating subsequent debit for the same PO for the remaining value of Rs 80. But this subsequent document is not getting blocked . According to me this subsequent document should also get blocked. Can some one help me why this problem. Is it a standard SAP functionality that subsequent document will not get blocked?
Deva

Please have a look for details
http://help.sap.com/saphelp_erp60_sp/helpdata/en/a8/b99725452b11d189430000e829fbbd/content.htm
Subsequent Debits/Credits are used in cases where the quantity is in the original invoice is to remain the same. For eg.
PO 10 - $10
Gr 10 - $10
LIV 10 - $11 (Logistics Invoice Verification)
The vendor invoice is more than that in the Purchase Order. In order to correct, the Vendor may send in another invoice for
the Increased amount or a credit memo for the increased amount.
If you approve of the price increase, post the subsequent invoice received as a Subsequent Debit/Credit Invoice.
If it is a credit memo that has been received, then post the credit memo as Subsequent Debit/Credit.
This would retain the quantity but reduce the amount.
Subsequent Debit/Credit is for the case when the credit is not for the full amount eg. if the Vendor decided to credit
only the $1 overcharged.
Credit memo is for the credit of the full amount and value.

OBIEE 11g Initialization Block problem with WLS User

Hello,
a brief description of my environment:
- I have one machine with all OBIEE 11.1.1.6.2 components (build 120604.0813 BP1 64bit) and Oracle Database 11gR2;
- In a separate machine I have the OID - Oracle Internet Directory where I have all business users with access to OBI Presentation Services;
- In Weblogic Console I created a user named "weblogic" and this one is the administrator of all BI environment, this user is member of BIAdministrator and Administrators group, also this user is used to perform the communication between Fusion Middleware and Weblogic;
- In weblogic Console I created a second user named "init_test" and he have the BIAuthor Role like the users that come from OID;
- I have no problem logging in with all users OID and weblogic.
Problem:
- I created a simple Initalization Block and a variable to contain the result of the follow sql: SELECT region FROM adm_test_region WHERE city='Lisboa'
- Initialization Blocks for Session variables are not working for "weblogic" user. For all other users everything is working as expected (users from OID and "init_test").
Question:
- There is any restriction in terms of Initialization Blocks for Session variables regarding the user that is linking Oracle Fusion Middleware with Oracle Weblogic?
Thank you in advance,

Thank you in advance,When you say they are not working:
1) You are using the session variables in a data filter in the RPD and for weblogic, the filter does not get applied?
2) When trying to display the value of the sessoin variable in an analysis query, it errors out saying no value?
As a BI Administrator, no data filters gets applied to the reports from the RPD unless you explicitly add them in the front end to the reports.
You can also open the RPD in online mode, and go to sessions and kill everything, login using weblogic and monitor the sessions to see if a session is being created and the list of variables getting intilialized upon weblogic's entry into analytics.
Thanks,

Creating temporary table in pl/sql block problem

hello
i have a problem in creating and using temporary table in pl/sql block
please verify below block
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
insert into alitemp1 (co_t,color) values ('001','red');
execute immediate 'DROP TABLE alitemp1';
end;
when i execute that block i will receive this error
insert into alitemp1 (co_t,color) values ('001','red');
ERROR at line 3:
ORA-06550: line 3, column 14:
PL/SQL: ORA-00942: table or view does not exist
ORA-06550: line 3, column 2:
PL/SQL: SQL Statement ignored
i think it because that alitemp1 table don't create
but two below block run fine
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
execute immediate 'DROP TABLE alitemp1';
end;
begin
execute immediate 'create global temporary table alitemp1 (co_t varchar2(10),color varchar2(10))';
end;
select table_name from user_tables where table_name='ALITEMP1';
TABLE_NAME
ALITEMP1
it means that problem is when the below line exists in block
insert into alitemp1 (co_t,color) values ('001','red');
if may please guide me

In addition to the comments by Justin and 3360, you cannot do what you want the way you are doing it.
All objects referred to in a PL/SQL block must exist at the time the block is compiled. In your case, since it is an anonomous block, that is run time. Since you are dynamically creating the temporary table you need to refer to it dynamically as well. More like:
BEGIN
EXECUTE IMMEDIATE 'create global temporary table alitemp1 (co_t varchar2(10),
color varchar2(10))';
EXECUTE IMMEDIATE 'insert into alitemp1 (co_t,color) values (:b1,:b2)' USING '001', 'red';
EXECUTE IMMEDIATE 'DROP TABLE alitemp1';
END;However, don't do that it is a really bad idea. Just create the temporary table, if you really need it, once and use it in your processing.
In most cases, things that SQL Server needs temporary tables for can be done easily in Oracle with a single SQL statement,

Weblogic 10 jsp compliation thread block problem

hi
i am using weblogic 10 and jdk1.5.
My application is deployed in ear format, with 2 wars, and 20 ejbs.
The ear works ok with weblogic 8.1.
In the application , one war passes the request to another war, that's the workflow....
Now when the request is passed on the second war, a jsp is supposed to open....but the application get stuck there.
The call is like this in a servlet....
     reqDisp = req.getRequestDispatcher("/newIndex.jsp");
reqDisp.forward(req, res);
The new index jsp is not opened....there is no problem with it it comiples ok....i check with weblogic appc...and it is working on weblogic 8.1.
when i stop the server...the log gives me following exception info.

We are using jBPM and Hibernate in our application which runs fine on other java application servers. On Weblogic we were getting an error:

Try block problem !

Hi all,
I have problem to compile java program which has a large block of try {}
This is the error message
C:\Program Files\crt_table.java:3011: code too large for try statement
catch (Exception e)
^
anyone has solution to this type of problem ?
Thanks in advance.

How many different types of exception are you trying to catch ?
Surely, if the try block is so big that the compiler is objecting, then you should be able to break the block down into smaller try blocks each of which is just catching one or two different exceptions. And perhaps you have code in this block which couldn't possibly cause an exception and doesn't need to be in a try block ?

Adobe InDesign Alternative Layouts - Problem

Hello, please, can you help me?
I want to use InDesign for a ebook. I use an alternative layout and wanted to save it as a PDF. But since the problems started. The PDF shows me now all alternative layouts (one after another), not only as the version for the tablet.
How can I make it so that I see on the tablet, use only the optimized version, but not even the PC version?
Und auf Deutsch:
Ich möchte InDesign für ein E-Book nutzen. Dazu habe ich zunächst alternative Layouts erstellt und wollte es mir als PDF ausgeben lassen. Beim PDF habe ich aber nun alle unters. Formate in einer Datei. Kann man es irgendwie so machen, dass ich 1 Datei habe und das PDF mir - je nachdem was ich nutze - die optimierten Versionen anzeigt oder muss ich wirklich alle alternativen Layouts seperat speichern?
Vielen Dank schon mal

WF_STANDARD.block Problem

Hi,
I have created a custom workflow which has a BLOCK node which pauses the workflow until some external application completes. After external activity gets completed, wf_engine.completeactivity() is executed so as to resume the wokflow and complete the process.
But problem is, workflow doesn't resumes even if wf_engine.completeactivity() executes without error.
Following is the syntax type for complete activity:
WF_ENGINE.completeactivity('ITEM_TYPE_ABC','ITEM_KEY_111','BLOCK-3','NULL');
'BLOCK-3' is the label of BLOCK node in workflow. NULL is used in last attribute as no result type is associated with BLOCK node. Also the status is 'NOTIFIED' for the activity.
Please indicate what could be the problem which is preventing the workflow from resuming?
Thanks in advance
Nitin

Hi,
I´ve noticed you use this BLOCK activity in multiple subprocess. Sou you should do this:
wf_engine.CompleteActivity(ORDER, 1003,ORDER_PROCESS:BLOCK3,
null);
Depending of your OWF version, your result should be 'None' instead of 'Null'

Luiz

Two Master and two details block problem

Hi,
I am getting problem in displaying the correct records on one of the detail block. There is one main master block 'A' and then it has one details block 'B' and then this detial block 'B' has got two details blocks 'c' and 'D'. I form different queries based on the value selected at detail block 'D'. Now i go to ,aster block and execute_query then it fetche the correct record at master block not on detail block 'D'. I have one anmoly in Dtails Block D and Master block B that they are joined with a common field not on the basis of proimary key and forign key. Please sugget

Hi,
When you establish the relations using the references, then oracle will look for the parent key in both the parent tables. Either you need to remove the foreign keys or change your db design to add one more table and have one-one parent child relationships.

Master/detail blocks problem

hi friends
i have a problem with master/detail blocks in my form.
i have two blocks one is master and the other one is detail
i made a relation between these two blocks
and my form works corectly
but when i am in enter_query mode ,my cursor cannot go to detail block.
so i can't search special records in detail block.
is there any way to search detail block's value in form builder?
is it true that in master/detail blocks we can serach records only in master records?
any help would be appretiated.
regards,
shoja.

When a Block is in Query Mode the cursor is restricted to it - there is nothing to stop you from Querying the Master and then navigating to the Detail and going into Enter Query mode in that block afterwards.
If you need to enter Query Criteria that applies to both the Master And Detail then you'll need to build a specialist query screen using a Non DB block that gathers all of the criteria and then uses SET_BLOCK_PROPERTY on both the master and the detail to define the required results.
