CALL SCREEN inside a FM ( parameter passing to PBO ) ?

Hello Friends,
I have the following issue:
I have a FM with some import parameter; inside the FM I am calling a screen. the screen has some input fields, and I have to set the value to input fields those import parameter of fm. I can staticaly set the input fields values in PBO, ( but as I said I need to take the values from FM ) is it possible ?
I try to set, in PBO ( pbo include ), but it did not recognise the FM import parameters---
Note, all those includes of PBO, and FM is in same FG....
Regards,

Hi guys,
Thanks for your input,
Problem solved, actually befoer calling the screen, I set the parameters:
like in my FM I have following code:
DESC_in = DESC.
LAUFZEIT_in = LAUFZEIT.
call screen 0100 STARTING AT 5 5.
Where as desc and laufzeit, are import parametes in the FM and desc_in and laufzeit_in are input fields on screen......
Anyway, thanks for your input..
Regards

Call screen inside EXIT_SAPMM07M_001

Hi Gurus,
Here's my problem - We have implemented EXIT_SAPMM07M_001. There's a CALL SCREEN 9000 inside the logic. What's weird is that inside our DEV box, the screen is being called without any problem. But when we transported it to our Quality box, when the program goes thru the command CALL SCREEN 9000, it does not go to the PBO modules but instead calls CONVERSION_EXIT_MATN1_OUTPUT for no apparent reason whatsoever.
I'm thinking it's because the screen contains an element MATNR. However, the other fields are not being populated due to the fact the PBO was not called.
Any thoughts? Let me know if you need more details. Thanks in advance!

Hi
check the request, probably there are some request that are not transported to the QAS system.
Regards.

Call screen into module program?

hi all,
i am trying to call the screen of sap standard program into my customized module program can anyone please tell me how to call screen of another program into my program?
thanks
john

Hi,
First set the values which needs to be passed using the following statement:
SET PARAMETER ID <pid> FIELD <f>.
then call your screen using the statement:
call screen 'SCREEN_NUMBER'.
if the screen is of a standard transaction then do set the required values through set parameter statement and then call the screen as
CALL TRANSACTION <tcod> [AND SKIP FIRST SCREEN] [USING <itab>].

To call methods inside the same application is possible to use RMI ?

hello,
What I should like to know is if RMI can easily be used to implement comunication (calling methods) inside classes that are part of the one same application... This should be a restrict case to use RMI...
The reason to do it come from the need to use the instance of a class knonwing it only as Object... This can be good to do if some code is used for general pupose in many different contexts.
In this case you can pass to the "server class" a parameter 'o' of type Object (all the classes extend Object) of the "customer class" to get back informations if some elaboration happen inside the "server class"...
This purpose is generally implemented with event listeners, but perhaps it could be done easily using RMI too (I dont know it...).
Using RMI in this simple situation, don't should require anything of complicate (stub, .... mashalling parametres....) to have the reference to method of the "customer class" to call. The "server class" already recives a reference of the "customer class" how parameter of type Object, and the mame of the method too.
I propose a simple thoeric example to explain really what I said before:
Class Server {
    String methodName;
    Object obj;
    pubic Server( Oject o , String metName){ // constructor
        obj = o;
        methodName = metName;
        // some thing is done and, at last, the method callbakMethod() is executed
        callbakMethod();
    }// constructor
    public void callbakMethod(){ // this method have the purpose to call customerMethod()
          Class c = owner.getClass();
          Method m = null;
              try {
                      m = c.getMethod("callBackMethod",null);
                     * // (1)
                      // I think that here we could have the possibility to call
                      // the method customerMethod() belonging to class Customer..
                      // I don't know if it possible and ... (and if it is possible) I am not able to do it*
    }// callbakMethod()
} // class Server
Class Custmer{
    public Customer() { // constructor
          Server s = new Server (this, "customerMethod");
    } // constructor
    customerMethod() {    // I would this method is called from class Server
        // do some thing.....
    } //customerMethod
} // class CustomerMy ask is: it is possible to call customerMethod() from the Server class ?...
If the aswer is yes, I wold know the sintax to use to do it, please.
thank you

RMI doesn't help you in the slightest here. You can just realize it all using local method invocation. All RMI does is to make that remote. If the objects aren't remote there is no point.

Issue with parameter passing in ie7 to php xml

Hi
I wondered if anyone could offer a little advice what the issue is here.
I have a page with xml generated from php in a separte file and presented by a dataset in spry.
The xml is OK and in firefox it all works but ie seems to barf on it.
The situation is this:
I have a jump menu on a front page that provides a url with anumeric parameter passed like this
platforms.php?platform_id=1
This parameter is picked up by php on the platforms.php page using the $_GET Array and is passed into the code in my Spry dataset to the file that runs my query and returns my xml- so basically the page displays a dataset filtered on this parameter id.
It works perfectly in FF.
In IE if I link straight to the page without a parameter at all- so platforms.php the page loads OK using the default parameter I have set up in the top of this page to send the default id of 1 to the code page so the spry query says platform_sql.php?platform_id=1 and the xml generator is fine with thisiel. ie I do a
if(isset($_GET['platform_id'])){
$platform=$_GET['platform_id'];
}else{
$platform=1;
The dataset loads Ok in IE but when I pass a parameter in the url from my jump menu IE gives a blank SPRY table i- it momentarily appears with just the placeholders for my dataset elements then vanishes. The source code of the page shows the correct id was set in the spry data going to my query file.
There is an error in ie saying there is a javascript error but its not any help- in ie fashion- FF shown no such errors.
I thought this might be a data type thing again in the dataset but its not - I have set the elements returned to simple strings but it still does not work.
Is there a problem passing in a parameter like this to a spry dataset?

After about half a day of mucking round I found the problem and a solution to this problem.
What appeared to have happened was that some of the older content in my database used html originally encoded using a WYSWYG editor called ktml.
Later data uses Tiny MCE. It looks like the character set of the two formats is slightly different and as a result some characters rendered incorrectly when passed through XML parsing where it specifies the character set as utf-8.
Firefox on the whole seems to ignore the issue though looking at the raw xml output of my php-xml code- where "-" characters were (dashes) there was a question mark character shown. None the less in actual use on my page the xml was produced and the dataset worked out.
In IE, it barfed at these same characters and failed to return the xml dataset.
What confused the issue more was some of my smaller datasets if they by chance never had a "-" character in rendered OK in IE- hence my default dataset (platform_id=1) worked in IE. After much experimenting I noticed other ids worked too if there was never such a character.
How I got round it was to wrap my server side data in the utf8_encode() function, and now all my xml is clean.
The javascript error being thrown was a red herring though I could not tell until I managed to run my page in ie7 with Visual Studio Express error console running- I had this on a spare machine at work so could debug with it.
All sorted now- now just need to find away to wrap all my datasets in collapsible panels that work.

Using Java Reflection to call a method with int parameter

Hi,
Could someone please tell me how can i use the invoke() of the Method class to call an method wiht int parameter? The invoke() takes an array of Object, but I need to pass in an array of int.
For example I have a setI(int i) in my class.
Class[] INT_PARAMETER_TYPES = new Class[] {Integer.TYPE };
Method method = targetClass.getMethod(methodName, INT_PARAMETER_TYPES);
Object[] args = new Object[] {4}; // won't work, type mismatch
int[] args = new int[] {4}; // won't work, type mismatch
method.invoke(target, args);
thanks for any help.

Object[] args = new Object[] {4}; // won't work, type
mismatchShould be:
Object[] args = new Object[] { new Integer(4) };The relevant part of the JavaDoc for Method.invoke(): "If the corresponding formal parameter has a primitive type, an unwrapping conversion is attempted to convert the object value to a value of a primitive type. If this attempt fails, the invocation throws an IllegalArgumentException. "
I suppose you could pass in any Number (eg, Double instead of Integer), but that's just speculation.

Handler called in library can only used passed variables?

I have been redoing a 3000-line program to put handlers in an assortment of libraries.
I've been getting a lot of variable undefined errors after calls to the handlers in the library.
Previously, I declared global variables and the handlers, when they were in the same script, had no problem with them.
Global variables do not seem to include handlers in called libraries as part of their scope.
In fact, I can't even Set a new variable in one of these handlers, unless it has first been passed as a parameter in the handler call.
For example, variable var1 in handler HandyHandler
set var1 to 1
results in a variable undefined error unless I call the handler:
HandyHandler(var1)
thus passing the variable from the main script.
This is more than a little awkward.
Is my perception correct: all variables in a handler must be defined in the calling script and passed as parameters?

Hello
It's hard to make advice without seeing actual codes. The boiled down essential version to demonstrate the problem would suffice. Also it might help to read the examples and explanations in the following threads.

Screen enhancement in ME51N - control is not passing to PBO and PAI of exit

HI ,
I am doing screen Exit for the Tcode : Me51N / Me52N.
I have to add 3 Text fields in item level, i am using Enhancement:MEREQ001(in CMOD).
Initially i added those 3 fields in Structure CI_EBANDB.
Then i designed Screen in Screen Exit:SAPLMEGUI Screen Num:111.
Here in the PBO and PAI Module
MODULE STATUS_0111 , MODULE USER_COMMAND_0111.
the control is not going , i tried with break-point inside these modules.
But while executing ME51N , debugger is not working.
Code i wrote in both PAI and PBO
MODULE STATUS_0111 and MODULE USER_COMMAND_0111.
loop AT SCREEN.
       screen-output = '1'.
       screen-input = '0'.
       MODIFY SCREEN.
endloop.
I need to display the three screen in Display format not in editable format.
Thanks and Regards,
Prakash K

Hi
You need to write the code in PBO of that screen based on TRANSACTION TYPE.
there is a method call 'get_transaction_state' from this you will get the transaction type (H - create , 'V'- change 'B' -display) at run time.
If run time transaction type = B
LOOP AT screen.
      IF screen-name eq c_name . "field names
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.
    ENDLOOP.
endif.

Parameter passing problem to standard JSP iView

Hi,
I'm trying to launch a standard iView with some a parameter directly from the browser by calling the url http://<server>/<iview>?<param>=<value>
The iView ID is com.sap.pct.hcm.ecmmain.approval and by looking at its details from the content catalog I saw there was a property called CREVI. I would like to fill this in but the iview doesn't respond to the URL params at all. Setting them staticly by editing the iView works perfect.
I have also checked that the "Parameters to pass from Page Request" property includes * and excludes some other properties than the one I'm testing.
I thought this was going to be simple but can't just make it work..I guess I'm missing something basic or the property can't be used? Any ideas?
Thanks,
Mikko

Hi Mikko,
We have found inconsistencies with regards to parameter passing in the URL, sometimes they are read and sometimes not. I suggest that you try to change the order of the parameters as this can affect if its read. I also believe other parameters can interfere whether or not it is read so try various scenarios.
Cheers,
John

Parameter passing by value or by reference in function module

hi everybody:
Im a beginner for abap.
Below description is described in online help.
In function module, the CALL FUNCTION statement can pass import, export, and changing parameters either by value or by reference. Table parameters are always transferred by reference.
I understand parameters passing by value means values carried by parameters are transferred, but I do not understand what is "by reference".
Please kindly give me a explanation.
Regards.
Andy

hi,
Function modules are modular units with interfaces. The interface can contain the following elements:
Import parameters are parameters passed to the function module. In general, these are assigned
standard ABAP Dictionary types. Import parameters can also be characterized as optional.
Export parameters are passed from the function module to the calling program. Export parameters
are always optional and for that reason do not need to be accepted by the calling program.
Changing parameters are passed to the function module and can be changed by it. The result is
returned to the calling program after the function module has executed.
Exceptions are used to intercept errors. If an error triggers an exception in a function module, the
function module stops. You can assign exceptions to numbers in the calling program, which sets the
system field SY-SUBRC to that value. This return code can then be handled by the program.
By reference Passes a pointer to the original memory location. Very efficient
By value Allocates a new memory location for use within the subroutine. The memory is freed when the subroutine ends. Prevents changes to passed variable
By value and result Similar to pass by value, but the contents of the new memory is copied back into the original memory before returning. Allows changes and allows a rollback
When you pass a parameter by reference, new memory is not allocated for the value. Instead, a pointer to the original memory location is passed. All references to the parameter are references to the original memory location. Changes to the variable within the subroutine update the original memory location immediately.
1 report ztx1804.
2 data f1 value 'A'.
3
4 perform s1 using f1.
5 write / f1.
6
7 form s1 using p1.
8 p1 = 'X'.
9 endform.
The code in Listing produces the following output:

Call transaction inside Update task

<b>Is it possible to use call transaction inside an update function module?</b>
My requirement is like this.
When I execute LB10 storage units will be created..then we have to go to lt09 and then create a TO's there for all these Storage units..
Now, when I try to call a bdc session from an exit, the storage units are not updated there. so the BDC is getting failed..
To resolve this, I kept all the BDC code in to a Zfunction module and made it an update funtion module. I am calling this function module form the exit IN UPDATE TASK.
But the call transaction is not working....
I have tried with L_TO_CREATE_MOVE_SU inside the Z function module..Still no use..
is there any other way that I can solve this?

Hi,
Calling a FM in Update Task is one of the bundling techniques used in ABAP to avail functionality provided by SAP Update System. Here all database updates are processed at the end of the SAP LUW in contrast to normal FM call where the database updates are done and commited at the time of call (Database LUW). It is necessary to bundle all your database updates in an SAP LUW e.g. all database updates in a transaction (like VA01) should be bundled. Almost all standard SAP transactions use bundling techniques.
This technique separates the dialog process and update process. The dialog part of the transaction can span more than one screen(one dialog step) and can be processsed by more than one dialog work process. A work process is released when the dialog step changes (screen changes) and the work process sends a database commit (called Implicit Database LUW). So with each screen change there is a database commit and database remains in consistent state.
Now when using bundling technique, when a COMMIT WORK is encountered, system ends the dialog process with a dialog work porcess and starts the update process using an update work process.
The dialog step containing the COMMIT WORK is considerd as the last dialog step of the transaction and all the update function modules are processed now in the last dialog step by the update work process though they were called earlier during the earlier dialog steps.
It is necessary to create update FMs to take advantage of this technique. The update FM is created FM by setting the Update moduleradiobutton in the Attributes tab in SE37.
In a normal FM call, if there are database updates (UPDATE, INSERT, MODIFY, DELETE) than database is commited after the FM processing is over as the FM starts its own Database LUW and ends it too.

Call Screen problem in a report

Hi All,
I have a report in which I am calling an ALV grid screen 1000. I select some line items and click on execute. On execution in the PAI I have called a function module which has a call screen statement inside it. This should call the screen 100 with tabstrip(This screen is not related to this report. This belongs to some other function group). But when I execute the report instead of calling the screen 100 again the screen 1000 is only being displayed. I have found that the PBO of screen 100 and all the subscreens in it are being called but after that this 100 screen not displayed as mentioned already. Please someone let me know if I am missing something somewhere.
Thank you,
Sri.

Hi Madhu,
I am calling the screen from PAI of the ALV grid screen. I have debuged and checked. The PBO of the screen and the corresponding subscreens is being called but after that instead of the wanted screen this ALV grid screen is being called. And when I press back button then again PAI of the actual screen is being called.
When the same FM is called from other classic reports without using ALV grid it is working fine.
Thanks,
Sri.

Call function inside running class

Hey All,
i have a two question in classes.
1- i have class and i called its before and its running on runtime. i need to call function inside this class from another class, but without call the first one again, because if i called it, it will run default class function again
is this doable ?
2- What super() mean ?
Thanks a lot.

this is the default call, and when i call the method by this way its will run the default class function before call the method.
here my example:
i need to call checkboxes function in ChannelsMain class without pass by the grey script.
Note: the call_cb is working and the trace is working
so i now the class is running, i need to call the checkboxes without ( var ci:YourClass = new YourClass(); )
package com.link
     import fl.controls.CheckBox;
     import flash.events.*;
     public class ChannelsMain
          var cbLength:uint = Main.PV.channel_id.length;
          public function ChannelsMain()
               // constructor code
               for (var i:int = 0; i < cbLength; i++)
                    var cb:CheckBox = new CheckBox;
                    cb.name = Main.PV.channel_id[i];
                    cb.label = Main.PV.channel_name[i];
                    cb.x = 50;
                    cb.y = 50 + i * 30;
                    cb.addEventListener(Event.CHANGE,call_cb);
                    Main.MS.addChild(cb);
                    //call xml function
                    if(i == cbLength - 1)
                         new ChannelsXML();
          private function call_cb(evt:Event)
               trace(evt.currentTarget.name,evt.currentTarget.selected);
          public function checkboxes(evt)
               trace(evt);

NEED PARAMETER PASSING SAMPLE INSTALLATION ZIP FILE...

Hello All,
I was viewing the following page:
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/
articles/guidelines.parameter.passing.html
Near the end of the page it reads, "For a detailed PL/SQL portlet
sample, see the Parameter Passing sample included in the PL/SQL
section including the Parameter Passing Sample Installation
article and check out the source code in the downloadable zip
file."
The phrase "downloadable zip" near the end of this line is a link
that is supposed to provide you with the zip file. When I click
on this link I get the file to save as sample.zip. Files get
downloaded but when I try to unzip it,
I encounter error messages :

Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.

let say i have a code as below:

         "Please enter a directory name:" );
      FileTreePanel panel = new FileTreePanel( rootDirectory );
      getContentPane().add( panel );
   }and i use this code to call the batch file:
import java.io.IOException;
public class callbatch{

               catch(IOException ioe) {
                    System.out.println(ioe);
     }how can i pass the rootDirectory into my callnvcc.bat?
