How to Call a standard screen with in a custom function module

Hi Guru,
I am copying a standard function module SWU_WF_TASK_DISPATCH in to Z function module in that they where calling a standard screen.
Some one help me how to copy or call this standard sceen within the function module.
Regards
Paul

Hi,
for that you have to create screen from SE51 same number in standard and program name should be the name of Z function group's main program and declare all varriable in function group's top inclue.
I think copy is not possible u have manually create screen for that.

Hello all,
Is it possible to use SAP JRA instead?
We have a Connector deployed on the WebAS 6.40. From an EJB (Webservice) it is possible to lookup the connector, but if i try to lookup the connector from a custom LoginModule, i get the following error:
Path to object does not exist at java:comp, the whole lookup name is java:comp/env/eis/SAPJRA_CRMDC.#
The whole lookup in LoginModule looks
try
               initialcontext    = new InitialContext();
               connectionFactory = (ConnectionFactory) initialcontext.lookup("java:comp/env/eis/SAPJRA_CRM");
          } catch (Exception ex)

Calling WebDynpro input screen from within an abap Function module / user

Hi,
I am posting SAP data with a BAPI from an Web Dynpro Application.
In the Bapi I must use an BADI/User -EXIT to add some infornation.
Today this is done by calling an Dynpro in a function module. This creates a pop up, data is filled and posted on commit.
How can I get a Web Dynpro application to display this popup without showing the "call screen without connection " error ?
Thanks for any help.

This approach is absolutely NOT supported nor recommended by SAP.

How to release a transport request with warnings using a function module?

Hi,
I want to release a transport request(which has some warnings) using some function module .
The warnign that i get when i try to release the Transport Request manually is "not all objects could be locked..."
Which function module can I use so i can release such a transport request?
I am currently using TR_RELEASE_REQUEST but I am unable to release the TR, it throws an exception.
Also i wouls assume that the function module mentioned would take care of releasing all the unreleased task
under the request.
Regards,
Bikash.

Hello Bikash
As an alternative (to cope with the warnings) you may use TRINT_RELEASE_REQUEST.
However, since this fm offers only a single task/request as IMPORTING parameter you need to take care about unreleased tasks yourself. Looking at SE09/SE10 even there you do not have the option the release a request including all its tasks.

*Submit report but export resultant list to memory, rather than

SUBMIT zreport EXPORTING LIST TO MEMORY.
Once report has finished and control has returned to calling

How to call legacy system screen in web dynpro for java?

Now I'm using Netweaver CE for building BPM (Business Process Management).
In BPM system, I wana call legacy system screen(ERP, C/S , Web, etc..) in web dynpro.
I'v already known how to call legacy system method and data.( using RMI, SOAP and RFC )
But I don't konw how to call legacy system screen.
If there is no way calling legacy system screen, I will have to build every screen using web dynpro.
It's so terrible.
So I think there is a way calling legacy system screen.
It's just my opinion.
If It can call legacy system screen in web dynpro, please let me know how to call it.
Or, If there is no way calling legacy system, how solve I this problem?
Thank you reading my question.

I assume that with "legacy system screen" you mean ABAP Dynp sceens. Of cause it would be attractive to integrate into new BPM processes. However there is a conceptional issue: You could easily integrate them e.g. into a WebDypro using a URL to to the so-called WebGUI (the ITS that makes Dynp screens Web enabled).
However the Dynp screen store all there state in the ABAP backend. This information is not available to to the process engine, e.g. to set the Task to completed or to use the data in Output Mapping.
In fact you need a way to wrap the how UI transaction into a WebDynpro screen including data flow.

How to call a standard sap transaction in workflow

Dear All,
I want to know how to call a standard sap transaction inside my workflow , please tell me how to get this done .
Kind Regards,
Anshu Kumar

Hi,
You can use the FM - ABAP4_CALL_TRANSACTION u2013 Initiates a transaction in a separate window
inside the method in the BO.
Implement that BO and the method in the Activity of the WF..!!
Use the FM like this:-
CALL FUNCTION 'ABAP4_CALL_TRANSACTION'
EXPORTING
    tcode                         = 'ZSCREEN_884' - T-Code
   SKIP_SCREEN                   = ' '
   MODE_VAL                      = 'A'
   UPDATE_VAL                    = 'A'
EXCEPTIONS
   CALL_TRANSACTION_DENIED       = 1
   TCODE_INVALID                 = 2
   OTHERS                        = 3
IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
If you do not want to use the FM u can use this Statement:-
call transaction 'ZSCREEN_884'. - T_CODE

How to call a AM method with parameters from Managed Bean?

Class[] paramTypes = { };
Object[] params = { } ;

This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };

I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.

Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you
thanks

How to call a standard BOR method in a program.

Hi All,
How to call a standard BOR method in a program. For example I have to call BOR method ISUSMORDER.Release in my program but don't know how to call.
Also, plz tell me how to capture the Exceptions in case of BOR method.
Plz help me out in this.
Thanks,
Mithilesh

Would be easier (however not always possible), to determine the functionality of this method and call that in your program. I mean, normally this method calls a BAPI, or function module (or a transaction). Have a look at the coding inside of the method, and try and use this.

How to call a Store Procedure with IN PARAMETER

SELECT * FROM procedure_name(parameter);
PROCEDURE procedure_name(parameter);

Hi,
As Beijing said,
EXEC procedure_name(parameter);
CALL procedure_name(parameter);work for me.
So does
BEGIN
procedure_name(parameter);
END;Can you be more specific about what you're doing? That is, are you testing it in SQL Developer? Where are you entering the commands? Where are you looking for output? Do you get error messages? Does anything else (like "SELECT SYSDATE FROM dual;") work?

how to lock the tauch screen with some password or dots like android to prevent misuse. And also screen lock to prevent interruption while watching movie reading books etc.

You can set a passcode to be requied to unlock the iPad via Settings > General > Passcode Lock. In terms of locking the actual screen whilst using an app, then that isn't currently possible, but with iOS 6 in the Autumn there will be a new 'accessibility' feature (from here) which will allow you :
... to limit an iOS device to one app by disabling the Home button, as well as restrict touch input on certain areas of the screen
