Proxy doesn't contain return value

Hi,
i have the following scenario: R/3(proxy) -> XI -> Webserivce(all interfaces are sync.)
i can see in the monitoring of XI that the webservice returns a value but this value is not passed to the proxy output parameter. The configuration is XI seems to be correct.
This is mijn code(i am not a abap person ):
The report should display a program name when the user submit a program code.
REPORT Z_HATP_WOS.
PARAMETERS: code type Z_HATP_PROGRAMCODE.
DATA: proxy TYPE REF TO ZES_CO_MI_PROGRAM_INFO_OUT_SY.
DATA: request type ZES_MT_REQ_PROGRAM_INFO.
DATA: inputParams type ZES_DT_REQ_PROGRAM_INFO.
DATA: response type ZES_MT_RES_PROGRAM_INFO.
DATA: outputParams type ZES_DT_RES_PROGRAM_INFO.
inputParams-CODE = code.
request-MT_REQ_PROGRAM_INFO = inputParams.
TRY.
CREATE OBJECT PROXY
EXPORTING
   LOGICAL_PORT_NAME =
CATCH CX_AI_SYSTEM_FAULT .
ENDTRY.
*TRY.
CALL METHOD PROXY->MI_PROGRAM_INFO_OUT_SY

    OUTPUT = response.
CATCH CX_AI_SYSTEM_FAULT .

write outputParams-title.
thanks very much,

Hi Peter,
extend ur programm.

to see the error.

MB52 doesn't show return quantyties values

Dear experts
After sales return, the qty shows under 'Returns'. But in MB51, corrosponding values are not shown under any column. can anybody guide on this issue, where i can see the return qty values? or in sap, return values doesn;t show in MB51?
Thanks

Hi,
This looks like a bug. A workaround is to set snapInterval=.1 as well as stepSize. Could you please log a bug on https://bugs.adobe.com/flex/?

Execution flow doesn't wait for return values

I have created JNI wrappers for existing dlls. However I'm getting weird behavior. My Java function calls a c function which communicates with an old mainframe. If I retrieve one row at a time its fine but if I do a loop the virtual machine crashes. Sometimes, if I add an empty loop for (30000 iterations) then its fine. Its like java is already trying to retrieve the next row while the first row is still being printed on my screen. I've tried adding synchronized in case the dlls where multi-threaded but it has not made a difference. Is there any way to control the execution flow so that it can't go to the next line until the values are truly returned from the c dll.
thanks
MA

There are many function being called on the native side. Since I didn't want to modify the native side
(because the old dlls are used by another application), I added my own dll as an intermediary between the old c dlls and the java side.
To fix the problem I am having, I've heard of another project where the native side would write the returned values to a file and only once the file is written can the Java side continue. Is this the only way to control the execution flow?
Right now I have about 5 empty loops which run to 100000 and things work most of the time. But I would prefer to find a way to say wait until the values are returned correctly.
Essentially, what I'm doing is
for (int i=1;i<10; i++){
   test.init(Integer.toString(i),Integer.toString(i),"english desc"+ Integer.toString(i),"french desc"+ Integer.toString(i));
   test.execute(test.ActionAdd);
}This is supposed to add one row with four fields. I'm just putting junk for the test. If I call the two main lines
test.init(Integer.toString(i),Integer.toString(i),"english desc"+ Integer.toString(i),"french desc"+ Integer.toString(i));
test.execute(test.ActionAdd);just once it works fine but if I loop them then it crashes after a few loops. If I put a loop as shown below then it works fine. This is part of the code when I'm adding. Is it being looped 10 times from the code above.
jsession.scanTable(table,errorlist);
            rtc = table.getRecordCount(errorlist);
            if (rtc > 0)
            publish(rtc+" records found.");
                for(int i = 1; i <= rtc; ++i)
                    for (int j = 0; j < ElementName.size();j++)
                        publish((String)ElementName.get(j)+ ": " + table.getFieldByName((String)ElementName.get(j),i,errorlist));
                        for (int k = 0; k<100000;k++);
            else
                publish("No records found.");
            }In the code, when the rows are added, I print them out just to make sure they were added correctly. This is where I got the idea that the Java code was not in synch with the native side because it would crash while writting out a line but it didn't happen every time at the same place.
This is the function getFieldByName
public String getFieldByName (String p_FieldName, int p_LineNum, ErrorList p_Errors)
          String retval = "";
          int ret;
          try
               p_FieldName = prepareFieldName(p_FieldName);

               StringBuffer m_FieldValue = new StringBuffer();
               // determining length of value
               int m_length[] = {0};
               ret = gti.GetFieldLen(this.ptrTableView, p_FieldName, m_length, eb.getErrorBlockPtr());
               if (m_length[0] == 0) m_length[0] = 100;
               m_FieldValue = new StringBuffer(m_length[0]);
               // get line field
               ret = gti.GetLineField(this.ptrTableView, p_FieldName, p_LineNum, m_FieldValue, eb.getErrorBlockPtr());
               if (ret != 0)
                      p_Errors.addMessage(p_Errors.SEV_ERROR(), "Error retrieving field value ("+p_FieldName+")");
               else
                      retval = m_FieldValue.toString();
          catch (Throwable t)
               p_Errors.addMessage(p_Errors.SEV_ERROR(), "Error retrieving field value ("+p_FieldName+")");
          return retval;
    }The main functions are
GetFieldLen
GetLineField
They go to the native side through my dll which wraps the old dlls.
Here are is one of the main functions in my dll. I also have the source for the functions they are calling but they are calling other functions which are calling other functions. There is a lot of code . Yes, they use arrays.

Job scheduling error : The return value was unknown. The process exit code was -1073741819. The step failed.

I am working in Sqlserver 2008 R2, SSIS 64 bit version
I am getting the below error while scheduling the job in the development server Database.
The return value was unknown. The process exit code was -1073741819. The step failed.
The SSIS front end execution runs fine.
Have anyone faced this issue before?

Hi Venkat,
If you already changed to 64bit and still doesn't work then create proxy account..
To create a proxy account
In Object Explorer, expand a server.
Expand SQL Server Agent.
Right-click Proxies and select New Proxy.
On the General page of the New Proxy Account dialog, specify the proxy name, credential name, and
description for the new proxy. Note that you must create a credential first before you create a proxy if one is not already available. For more information about creating a credential, see How
to: Create a Credential (SQL Server Management Studio) or CREATE CREDENTIAL (Transact-SQL).
Check the appropriate subsystem for this proxy.
On the Principals page, add or remove logins or roles to grant or remove access to the proxy account.
Thanks

Trying to write an if statement around the return value of a CANCEL_OPTION

I am writing a program that takes an input String using JOptionPane. The String can be made of only letters of the A-Z alphabet and the space character. I have written an error-checking loop that will pop another input box up along with an error message if any invalid character is detected. The input box has an 'ok' button and a 'cancel' button. As it is, if you hit cancel, the program crashes and you get a NullPointerException. All I want to do is place an if statement inside of the error-checking loop, immediatly after the code to pop up the second input box, that simply does System.exit() and exits the program correctly(rather than crashing) if 'cancel' is clicked.
My attempt at such an if statement is visible in the following code(letter is a boolean variable defined earlier, and message is the input String that has already been read in):
               letter = isValidMessage(message);
          while(!letter)
               message = JOptionPane.showInputDialog(null, "Message must contain only A-Z, a-z, or space character...");
                        if(JOptionPane.CANCEL_OPTION > 0 //or ==0 or ==1 or ==2, nothing works//)
                            JOptionPane.showMessageDialog(null, "No valid message entered - program will terminate...");
                            System.exit(JOptionPane.CANCEL_OPTION);
               letter = isValidMessage(message);
                }The if statement doesn't work correctly. If you click 'cancel' when the input box comes up, the program does terminate as it is supposed to. The problem is that if I type something in the box and click 'ok', it also causes the program to terminate rather than continuing. I've tried changing the > to ==. I've tried changing 0 to 1 to 2 to -1(I really am not sure which int return value of CANCEL_OPTION corresponds to which event). I think once I got to do the exact opposite...that is to say, it would continue on with the program whether I clicked 'cancel' or 'ok'. Which is equally bad. I don't know what I'm doing wrong.
It's probably something simple that I'm just overlooking.

Well, here's what CANCEL_OPTION is, according to the JOptionPane class:
/** Return value from class method if CANCEL is chosen. */
    public static final int         CANCEL_OPTION = 2;However, I believe you're going about this in the wrong way.
With JOptionPane, whenever you show a dialog, it usually returns whatever OPTION the user chose.
For instance,
    int choice = JOptionPane.showConfirmDialog(parentComponent, "hello");That will bring up a dialog centered on parentComponent, with a message of "hello".
It will have the default options (YES_NO_OPTION).
What it returns is the option the user chose.
There are 4 possible things it can return:
YES_OPTION, when user clicks "Yes"
NO_OPTION, when user clicks "No"
ERROR_OPTION, when an unforseen error occurs and the dialog closes
CANCEL_OPTION, when the user clicks "Cancel" (if that OPTION type were being used), or if they close the dialog
So this is how you would check for CANCEL_OPTION:
    int choice = JOptionPane.showConfirmDialog(parentComponent, "hello");
    if (choice == JOptionPane.CANCEL_OPTION) {
        // User cancelled
    else if (choice == JOptionPane.YES_OPTION) {
        // User chose yes
    // EtcSo you see, going about it like this:
if(JOptionPane.CANCEL_OPTION > 0 //or ==0 or ==1 or ==2, nothing works//)Is really the wrong way, because you're not checking what the user DID, but just what the constant variable "CANCEL_OPTION" is.
However, it seems as if you're in a unique situation where you don't want the OPTION chosen by the user, but an input String.
This is all well and good, but I think this limits how you can interact with the user, as the "showInputDialog" methods return the String the user input- not the OPTION they chose, and you need to use both.
What I've done in the past is created a simple JPanel with its own JTextField.
I pass the JPanel in as the "message" parameter of a showConfirmDialog call, and get both the user input and their chosen OPTION based off a getText call to the JTextField and the OPTION constant returned by showConfirmDialog.
Basically,
JPanel promptPanel = new JPanel(new BorderLayout());
JTextField promptField = new JTextField();
promptPanel.add(promptField, BorderLayout.CENTER);
int choice = JOptionPane.showConfirmDialog(parentComponent, promptPanel, "Input", JOptionPane.OK_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE);
if (choice == JOptionPane.OK_OPTION) {
   // User chose OK, see if invalid characters were entered
   String input = promptField.getText();
else if (choice == JOptionPane.CANCEL_OPTION) {
   // User cancelled
}Hope that helps.
(note that I'm unsure if showConfirmDialog can accept OK_CANCEL_OPTION as its OPTION parameter, as it says only YES_NO_OPTION and YES_NO_CANCEL_OPTION can be used, but I seem to remember using it in the past. if OK_CANCEL_OPTION doesn't want to work, then use one of the other two and adjust your if statements accordingly)
Cheers!

Problem with Bapi_po_Getdetail return values

We have developed a web service in asp.net to get the details of a particular purchase order number calling Bapi_po_Getdetail. The input parameters that we pass are:
string ITEMS = X
string PURCHASEORDER= <purchase order number>
But when we debug and check the return values from the bapi, BAPIEKPO Table doesnt have any data, it is null.
Could someone help us, please?

Please initialize the BAPIEKPOTable bedore call. Passing null allways returns null.
NCo:
string ITEMS = X
string PURCHASEORDER= <purchase order number>
BAPIEKPOTable result = new BAPIEKPOTable();
proxy.Bapi_po_Getdetail(ITEMS, PURCHASEORDER, ref result);
Soap Processor / Web Service Wizard
string ITEMS = X
string PURCHASEORDER= <purchase order number>
BAPIEKPO[] result = new BAPIEKPO[0];
proxy.Bapi_po_Getdetail(ITEMS, PURCHASEORDER, ref result);

Call C# method from javascript in WebView and retrieve the return value

The issue I am facing is the following :
I want to call a C# method from the javascript in my WebView and get the result of this call in my javascript.
In an WPF Desktop application, it would not be an issue because a WebBrowser
(the equivalent of a webView) has a property ObjectForScripting to which we can assign a C# object containg the methods we want to call from the javascript.
In an Windows Store Application, it is slightly different because the WebView
only contains an event ScriptNotify to which we can subscribe like in the example below :
void MainPage_Loaded(object sender, RoutedEventArgs e)
this.webView.ScriptNotify += webView_ScriptNotify;
When the event ScriptNotify is raised by calling window.external.notify(parameter), the method webView_ScriptNotify is called with the parameter sent by the javascript :
function CallCSharp() {
var returnValue;
window.external.notify(parameter);
return returnValue;
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = DoSomerthing(parameter);
The issue is that the javascript only raise the event and doesn't wait for a return value or even for the end of the execution of webView_ScriptNotify().
A solution to this issue would be call a javascript function from the webView_ScriptNotify() to store the return value in a variable in the javascript and retrieve it after.
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = ReturnResult();
await this.webView.InvokeScriptAsync("CSharpCallResult", new string[] { result });
var result;
function CallCSharp() {
window.external.notify(parameter);
return result;
function CSharpCallResult(parameter){
result = parameter;
However this does not work correctly because the call to the CSharpResult function from the C# happens after the javascript has finished to execute the CallCSharp function. Indeed the
window.external.notify does not wait for the C# to finish to execute.
Do you have any solution to solve this issue ? It is quite strange that in a Window Store App it is not possible to get the return value of a call to a C# method from the javascript whereas it is not an issue in a WPF application.

I am not very familiar with the completion pattern and I could not find many things about it on Google, what is the principle? Unfortunately your solution of splitting my JS function does not work in my case. In my example my CallCSharp
function is called by another function which provides the parameter and needs the return value to directly use it. This function which called
CallCSharp will always execute before an InvokeScriptAsync call a second function. Furthermore, the content of my WebView is used in a cross platforms context so actually my
CallCSharp function more look like the code below.
function CallCSharp() {
if (isAndroid()) {
//mechanism to call C# method from js in Android
//return the result of call to C# method
} else if (isWindowsStoreApp()) {
window.external.notify(parameter);
// should return the result of call to C# method
} else {
In android, the mechanism in the webView allows to return the value of the call to a C# method, in a WPF application also. But I can't figure why for a Windows Store App we don't have this possibility.

How to stop SQL Server Agent Job if Stored Procedure returns value 0

I have SQL Server 2012 SSIS.
I have 2 SSIS packages.
I have created SQL Server Agent Job for running packages.
I have created steps. If first step have run succesfully next step is run.
I have need to add new logic.
I have validation stored procedure, which validate DB table values and returns 1 or 0.
I would like to create logic where first of all this SP is runned. Return value of SP determines if steps are run or not.
I was thinking to use Execute SQL Task for running SP.
If value 1 is returned, then run rest of Tasks is run.
If value 0 is returned, what should I do so that Job is stopped? I need assistance!
I want current step to stop never moved to next step.
Is there any SSIS tasks, which can stop the Job?
Or should I make Step for running validation SP?
How to do so that if value 0 is returned stop Job.

Please read Remarks carefully!!!
Remarks
If a job is currently executing a step of type CmdExec, the process being run (for example, MyProgram.exe) is forced to end prematurely. Premature ending can result in unpredictable behavior such as files in use by the process being held open. Consequently,
sp_stop_job should be used only in extreme circumstances if the job contains steps of type CmdExec.
Permissions
Execute permissions default to the public role in the
msdb database. A user who can execute this procedure and is a member of the
sysadmin fixed role can stop any job. A user who is not a member of the
sysadmin role can use sp_stop_job to stop only the jobs he/she owns.
When sp_stop_job is invoked by a user who is a member of the
sysadmin fixed server role, sp_stop_job will be executed under the security context in which the SQL Server service is running. When the user is not a member of the
sysadmin group, sp_stop_job will impersonate the SQL Server Agent proxy account, which is specified using
xp_sqlagent_proxy_account. If the proxy account is not available,
sp_stop_job will fail. This is only true for Microsoft® Windows® NT 4.0 and Windows 2000. On Windows 9.x, there is no impersonation and
sp_stop_job is always executed under the security context of the Windows 9.x user who started SQL Server.

Scr doesn't contain powerup

I discovered that my script file doesn't contain the powerup.

I know somethings wrong with my walletApp.scr,
may I have your advise,
Thanx

Sorry...
I think I was too careless.
I managed to open the .scr file already.
I have added some scripts into it and it works properly.
The scripts I've added:
powerup;

powerdown;
But I discovered that my walletApp.scr is totally different with the sample given in the walletdemo directory.

Multiple return values (Bug-ID 4222792)

I had exactly the same request for the same 3 reasons: strong type safety and code correctness verification at compile-time, code readability and ease of mantenance, performance.
Here is what Sun replied to me:
Autoboxing and varargs are provided as part of
JSRs 14 and 201
http://jcp.org/en/jsr/detail?id=14
http://jcp.org/en/jsr/detail?id=201
See also:
http://forum.java.sun.com/forum.jsp?forum=316
http://developer.java.sun.com/developer/earlyAccess/adding_generics/index.html
Multiple return values is covered by Bug-ID 4222792
Typically this is done by returning an array.
http://developer.java.sun.com/developer/bugParade/bugs/4222792.html
That's exactly the problem: we dynamically create instances of array objects that would better fit well within the operand stack without stressing the garbage collector with temporary Array object instances (and with their backing store: 2 separate allocations that need to be recycled when it is clearly a pollution that the operand stack would clean up more efficiently)
If you would like to engage in a discussion with the Java Language developers, the Generics forum would be a better place:
http://forum.java.sun.com/forum.jsp?forum=316
I know that (my report was already refering to the JSR for language extension) Generics is not what I was refering to (even if a generic could handle multiple return values, it would still be an allocated Object
instance to pack them, i.e. just less convenient than using a static class for type safety.
The most common case of multiple return values involve values that have known static datatypes and that should be checked with strong typesafety.
The simple case that involves returning two ints then will require at least two object instances and will not solve the garbage collection overhead.
Using a array of variable objects is exactly similar, except that it requires two instances for the components and one instance for the generic array container. Using extra method parameters with Integer, Byte, ... boxing objects is more efficient, but for now the only practical solution (which causes the least pollution in the VM allocator and garbage collector) is to use a custom class to store the return values in a single instance.
This is not natural, and needlessly complexifies many interfaces.
So to avoid this pollution, some solutions are used such as packing two ints into a long and returning a long, depacking the long after return (not quite clean but still much faster at run-time for methods that need to be used with high frequencies within the application. In some case, the only way to cut down the overhead is to inline methods within the caller code, and this does not help code maintenance by splitting the implementation into small methods (something that C++ can do very easily, both because it supports native types parameters by reference, and because it also supports inline methods).
Finally, suppose we don't want to use tricky code, difficult to maintain, then we'll have to use boxing Object types to allow passing arguments by reference. Shamely boxed native types cannot be allocated on the operand stack as local variables, so we need to instanciate these local variables before call, and we loose the capacity to track the cases where these local variables are not really initialized by an effective call to the method that will assign them. This does not help debugging, and is against the concept of a strongly typed language like Java should be:
Java makes lots of efforts to track uninitialized variables, but has no way to determine if an already instanciated Object instance refered in a local variable has effectively received an effective assignment because only the instanciation is kept. A typical code will then need to be written like this:
Integer a = null;
Integer b = null;
if (some condition) {
//call.method(a, b, 0, 1, "dummy input arg");
// the method is supposed to have assigned a value to a and b,
// but can't if a and b have not been instanciated, so we perform:
call.method(a = new Integer(), b = new Integer(), 0, 1, "dummy input
arg");
// we must suppose that the method has modified (not initialized!)
the value
// of a and b instances.
now.use(a.value(), b.value())
// are we sure here that a and b have received a value????
// the code may be detected at run-time (a null exception)
// or completely undetected (the method() above was called but it
// forgot to assign a value to its referenced objects a and b, in which
// case we are calling in fact: now.use(0, 0); with the default values
// or a and b, assigned when they were instanciated)
Very tricky... Hard to debug. It would be much simpler if we just used:
int a;
int b;
if (some condition) {
(a, b) = call.method(0, 1, "dummy input arg");
now.use(a, b);
The compiler would immediately detect the case where a and b are in fact not always initialized (possible use bere initialization), and the first invoked call.method() would not have to check if its arguments are not null, it would not compile if it forgets to return two values in some code path...
There's no need to provide extra boxing objects in the source as well as at run-time, and there's no stress added to the VM allocator or garbage collector simply because return values are only allocated on the perand stack by the caller, directly instanciated within the callee which MUST (checked at compile-time) create such instances by using the return statement to instanciate them, and the caller now just needs to use directly the variables which were referenced before call (here a and b). Clean and mean. And it allows strong typechecking as well (so this is a real help for programmers.
Note that the signature of the method() above is:
class call {
(int, int) method(int, int, String) { ... }
id est:
class "call", member name "method", member type "(IILjava.lang.string;)II"
This last signature means that the method can only be called by returning the value into a pair of variables of type int, or using the return value as a pair of actual arguments for another method call such as:
call.method(call.method("dummy input arg"), "other dummy input arg")
This is strongly typed and convenient to write and debug and very efficient at run-time...

Can anyone give me some real-world examples where
multiple return values aren't better captured in a
class that logically groups those values? I can of
course give hundreds of examples for why it's better
to capture method arguments as multiple values instead
of as one "logical object", but whenever I've hankered
for multiple return values, I end up rethinking my
strategy and rewriting my code to be better Object
Oriented.I'd personally say you're usually right. There's almost always a O-O way of avoiding the situation.
Sometimes though, you really do just want to return "two ints" from a function. There's no logical object you can think of to put them in. So you end up polluting the namespace:
public class MyUsefulClass {
public TwoInts calculateSomething(int a, int b, int c) {
public static class TwoInts {
    //now, do I use two public int fields here, making it
    //in essence a struct?
   //or do I make my two ints private & final, which
   //requires a constructor & two getters?
//and while I'm at it, is it worth implementing
//equals(), how about hashCode()? clone()?
//readResolve() ?
}The answer to most of the questions for something as simple as "TwoInts" is usually "no: its not worth implementing those methods", but I still have to think about them.
More to the point, the TwoInts class looks so ugly polluting the top level namespace like that, MyUsefulClass.TwoInts is public, that I don't think I've ever actually created that class. I always find some way to avoid it, even if the workaround is just as ugly.
For myself, I'd like to see some simple pass-by-value "Tuple" type. My fear is it'd be abused as a way for lazy programmers to avoid creating objects when they should have a logical type for readability & maintainability.
Anyone who has maintained code where someone has passed in all their arguments as (mutable!) Maps, Collections and/or Arrays and "returned" values by mutating those structures knows what a nightmare it can be. Which I suppose is an argument that cuts both ways: on the one hand you can say: "why add Tuples which would be another easy thing to abuse", on the other: "why not add Tuples, given Arrays and the Collections framework already allow bad programmers to produce unmainable mush. One more feature isn't going to make a difference either way".
Ho hum.

Help : Complex parameter and return value in WebService?

Hi guys
   These days, I publish a WebService, in it there is an
operation like this:
   List search(List para);
   in this operation, parameter "para" is a java.util.List, which contains many elements, every element is an instance of customizing class "MyItem", I made "MyItem" implements java.io.Serializable interface. Strangely, when I call this operations in my java client,
I found that I could not get out every element from para in server-side, but para.size() is showing it contains 10 elements in it. The same thing happen to the return value of this operation, in client, I got an instance of java.util.List class as the return value, when I try
System.out.println(result.get(0)); it output "null", but
result.size() is 10, I don't know how to explain this
   Does anyone who encounter this issue too?
I guess it has something to with the Serializable issue ,but I have made every List item serializable, why it looks like this??

Hi Kevin,
I answered you by mail some days ago, but just to complete the thread, I am posting the hint also here:
Custom types should be manually added to the Virtual Interface, so that they can be serialized.
Best regards,
Alexander

How to Change the return value for the parameters

Hi, Can anyone help me with my problem?
I have a parameter called "P1_Projects" defined in the HTMLDB page, on the report region, there are 2 buttons, one is "Go" button to submit the report on the screen, so user can preview the report, then another button "Export to PDF" can be clicked to generate the report using Oracle Report Services. The "Export to PDF" button will use the same set of parameters submitted for the "Go" button.
So, the parameter "P1_Projects" is being used by these 2 buttons. and I have to pass a "%" wild card for "All Projects". To make the "Export to PDF" button work, I have to safe encode the return value for "%" to "%25" in order to pass the URL formula, but now my "Go" button doesn't work with "%25", it only recognize the "%" wild card.
Is there a way to conditionally change the value depends which button is clicked?
Any hint or help is highly appreciated!

try creating a plsql process which sets the P1_Projects item as required.
in the plsql you can do:
if :REQUEST = 'GO' then
xxx
else
xxxx
end if;
set the condition to plsql expression:
:REQUEST in ('GO', 'EXPORT')
NB. the request value is usually set to the button name when a page is submitted from a button

How to create a display value and a return value for an item

Hi! I have an item on a form. I want the default value for my item to be :":APP_USER", but the return value, to be the id of my user. I tried to create a PL/SQL Expression for the default item, but it doesn't work. What do I miss?
It should be something like this, but it's not.
begin
select first_name || ',' ||last_name as "Employee",
id_employee -- display value,return value
from employees
where id_employee = :APP_USER;
end;
Does anyone know?
Thanks!
Vitaly

Hi VItaly,
Display value and return value concept applies very well in case of a Combo box if i am correct, I don't know what type of item is your's.
But any way, you can have a workaround like,
Create a hidden item such that it's default value should be ID of the user which can be get from db by using :APP_USER.
Use the this item for your references.
I think this will meet your requirement.
Thanks

How to set the returned value of CFL in a matrix

dear all,
I got a matrix binded to a DataSource and two CFLs are in this matrix. The codes for handling AfterChooseFromList is as following. It works almost fine. But when a docoment containing more than two
rows in the matrix and I reselect the CFL cell values more than two times, an error occured sometimes, not everytime. The error message is "This entry already exists in the following tables @CYW_PRROW [Message 131-183]"
I have tried to find out what kind of situation to cause this error, but still in the mud.
Can anybody give me some suggestion? Thanks.
Public Sub OnAfterChooseFromList_Matrix(ByVal pVal As SAPbouiCOM.ItemEvent)
        Dim ActionSuccess As Boolean = pVal.ActionSuccess
        Dim oform As SAPbouiCOM.Form = SBO_Application.Forms.Item(pVal.FormUID)
        Dim oitem As SAPbouiCOM.Item = oform.Items.Item("mtx_0")
        Dim omatrix As SAPbouiCOM.Matrix = CType(oitem.Specific, SAPbouiCOM.Matrix)
        Dim oDataTable As SAPbouiCOM.DataTable
        oDataTable = pVal.SelectedObjects
        Dim val As String
        Try
            val = oDataTable.GetValue(0, 0)
        Catch ex As Exception
        End Try
        omatrix.GetLineData(pVal.Row)
        oform.DataSources.DBDataSources.Item("@CYW_PRROW").Offset = pVal.Row - 1
        If pVal.ColUID = "col_0" Then
            Try
                oform.DataSources.DBDataSources.Item("@CYW_PRROW").SetValue("U_PRItemCode", pVal.Row - 1, CStr(val))
            Catch ex As Exception
                SBO_Application.MessageBox(ex.Message)
            End Try
        Else
            Try
                oform.DataSources.DBDataSources.Item("@CYW_PRROW").SetValue("U_PRSupp", pVal.Row - 1, CStr(val))
            Catch ex As Exception
                SBO_Application.MessageBox(ex.Message)
            End Try
        End If
        omatrix.SetLineData(pVal.Row)
        If pVal.FormMode = "1" Then
            oform.Mode = SAPbouiCOM.BoFormMode.fm_UPDATE_MODE
        End If
    End Sub
Another quesion, can I assign the returned value of CLF directly to the cell?

Hello Chao-Yi Wu,
I don't have a real solution for you - just a few comments:
1. At
        Try
            val = oDataTable.GetValue(0, 0)
        Catch ex As Exception
        End Try
I would add
        Try
            if oDataTable Is Nothing Then Exit Sub ' If the User cancels the CFL
            val = oDataTable.GetValue(0, 0)
        Catch ex As Exception
        End Try
2. At
   If pVal.ColUID = "col_0" Then
I would make the branch by the pVal.ChooseFromListUID instead of the ColUID
and the 2nd not with "Else" but with "Else If ....."
3. It may work with EditText.String/Value of a cell but I never do that because of performance-reasons.
I always do it the same way as you in principle - I don't really know what the problem is.
4. Maybe some unique indexes on your table (although this should give an error at the update and not at CFL when "the unique-law is broken"...)?
Sorry - that's all for the moment.
Cheers,
Roland

How to call an Oracle Procedure and get a return value in Php

Hi Everyone,
Has anyone tried calling an Oracle procedure from Php using the ora functions and getting the return value ? I need to use the ora funtions (no oci)because of compatibility and oracle 7.x as the database.
The reason why I post this here is because the ora_exec funtion is returning FALSE but the error code displayes is good. Is this a bug in the ora_exec funtion ?
My code after the connection call is as follows:
$cur = ora_open($this->conn);
ora_commitoff($this->conn);
$requestid = '144937';
echo $requestid;
$rc = ora_parse($cur, "begin p_ins_gsdata2
(:requestid, :returnval); end;");
if ($rc == true) {
echo " Parse was successful ";
$rc2 = ora_bind ($cur, "requestid", ":requestid", 32, 1);
if ($rc2 == true) echo " Requestid Bind Successful ";
$rc3 = ora_bind ($cur, "returnval", ":returnval", 32, 2);
if ($rc3 == true) echo " Returnval Bind Successful ";
$returnval = "0";
$rc4 = ora_exec($cur);
echo " Result = ".$returnval." ";
if ($rc4 == false) {
echo " Exec Returned FALSE ";
echo " Error = ".ora_error($cur);
echo " ";
echo "ErrorCode = ".ora_errorcode($cur);
echo "Error Executing";
ora_close ($cur);
The Oracle procedure has a select count from a table and it returns the number of records in that table. It's defined as:
CREATE OR REPLACE procedure p_ins_gsdata2 (
p_requestid IN varchar2 default null,
p_retcode OUT varchar2)
as
BEGIN
SELECT COUNT (*) INTO p_retcode
FROM S_GSMRY_DATA_SURVEY
WHERE request_id = p_requestid ;
COMMIT;
RETURN;
END;
Nothing much there. I want to do an insert into a table,
from the procedure later, but I figured that I start with a select count since it's simpler.
When I ran the Php code, I get the following:
144937
Parse was successful
Requestid Bind Successful
Returnval Bind Successful
Result = 0
Exec Returned FALSE
Error = ORA-00000: normal, successful completion -- while
processing OCI function OBNDRA
ErrorCode = 0
Error Executing
I listed the messages on separate lines for clarity. I don't understand why it parses and binds o.k. but the exec returns false.
Thanks again in advance for your help. Have a great day.
Regards,
Rudi

retcode=`echo $?`is a bit convoluted. Just use:
retcode=$?I see no EOF line terminating your input. Your flavour of Unix might not like that - it might ignore the command, though I'd be surprised (AIX doesn't).
replace the EXEC line with :
select 'hello' from dual;
and see if you get some output - then you know if sqlplus commands are being called from your script. You didn't mentioned whether you see the banner for sqlplus. Copy/paste the output that you get, it will give us much more of an idea.

Proxy doesn't contain return value
