Its not me deleting them. Perhaps a different moderator or a technical problem within SCN itself.
Someone might be concerned about your question because it is very basic.
You can call a function module from WD the same way you did in any ABAP program - with the CALL FUNCTION syntax. There is a service call wizard that will generate a matching context and calling code for you - but it is just a helper, code generator. Everything it does can be done by hand as well (and often better than the generator).

Calling a function module from a Web Template

Hi,
I need to call a function module from a web template. Any pointers on how i can do this ? Is this even possible ?
Thanks
Shailesh

Hi Rael,
We were finally able to call a FM module from the Web. The trick as Heike suggested was to create an ABAP class which inherits from CL_RSR_WWW_HELP_WINDOW. Then you should modify the process_cmd method of this new class in order to call the FM. Now use this class to create a help service. In case you need to pass any parameters to the FM, you will need to pass them as additional parameters while calling the help service.
An example is below.
CMD=PROCESS_HELP_WINDOW&HELP_SERVICE=ZBOOKMARKING&TEXT=mytext&URL=myurl
Where mytext and myurl were the parameters i pass to my FM and ZBOOKMARKING is my help service.
Thanks a Lot to Heike for his help on this !!

Can you call a function module from within a smartform?

I was told that yu can not call a function module from a smartform - that does not make sense to me because you can do tons of ABAP within a smartform.
Well - can you?
Thanks.

Yes, you can call function modules.

How do you call a function within a package using OCI in C

I am trying to call a user-defined function in Oracle 8.1.7 using OCI in C. I am getting a ORA-06550 PLS-00221, <function name> is not a procedure or is undefined. Can anyone tell me how I would call a function using OCI?
Thanks.

I think I figured it out, but I am now getting a ORA-06512 error; numeric or value error: character string buffer too small.

How do you call a function in an attached MovieClip from the current MovieClip?

Hi there,
I have this MovieClip A (converted as a symbol) and put in my
main MovieClip B using attachMovie() , and I am wondering how I can
call a function defined in A from within B.
Is it possible?
Thanks

Hi kglad,
yes, I did the attachMovie of the symbol B and it seems like
none of the ActionScript written in B was not carried over.
This is how I built B into a symbol :
(1) Two layers ( one for the ActionScript only, the other for
the Components)
(2) I defined the functions to be called remotely by A in the
ActionScript layer
(3) I selected all the components in the Components Layer and
did a Convert To Symbol
(4) I added the Symbol into A's Library
(5) I used attachMovie to instantiate the Symbol of B
I must have missed out something somewhere
Thanks

Assigning a login module to a Web Dynpro application

Hi everybody,
I would like a Web Dynpro application to use a custom login module for authentication. How can I do this?
What I found is the Security Provider (in the Visual Administrator tool) where I can add a login module to the "form" authentication mechanism for example. But if I do this I think all applications using this mechanism have to use my custom login module, right?
I wonder if I have to add my Web Dynpro application as a component to the Security Provider so that I can assign login modules to it. Am I on the right way? If yes, how can I do this? If I choose "Add" from the "Policy Configurations" tab a popup appears where I can enter the name for a new component. How do I specify my application there?
Thanks in advance for all answers,
Torben

Hi,
Web Dynpro applications use the ticket authentication template. U wud need to add your login module to the ticket template's login stack.
Incase you are accessing the Web Dynpro applications thru the EP u wud need to make changes to the authschemes.xml file too.

Vishal

How to make use of Portal service in the web dynpro application

hi
I have some portal service and how to use that in the web dynpro application.
and also what is the main diff between Portal Component and web dynpro application.
do we required portal to run web dynpro application.
thanks
mmukesh

Hi,
>> I have some portal service and how to use that in the web dynpro application.
Yes. U can use Portal service in webdynpro. Check the link given by subathra.
>> and also what is the main diff between Portal Component and web dynpro application
Portal Components are components designed to run in portal server while webdynpro application can run in J2EE WebAS.
>> do we required portal to run web dynpro application.
No for general cases. Just WebAS is sufficient to run webdynpro appl. But if u use portal service in ur webdynpro appl, then make sure both (portal service and webdynpro appl) run on same J2EE engine. That is mandatory.

How do you call a function that belongs in a package?

Hello,
Can anyone help me with this issue? My intent is to create a procedure that returns a cursor to the results of the query without passing in the cursor to the function. After reading thru online tutorials, I found that I had to create a function, not a procedure.
I created a .sql file as such:
create or replace package GetEmployeeCursors is
type empResultSet is REF CURSOR;
function Funct1 return empResultSet;
end GetEmployeeCursors;
create or replace package body GetEmployeeCursors is function Funct1 return
empResultSet is
tmpResultSet empResultSet;
begin
open tmpResultSet for
select * from employee;
return tmpResultSet;
end Funct1;
end GetEmployeeCursors;
Both the package and package body were created without any problems.
Then, I tried to call the Funct1() in many ways, including the following:
call System.getEmployeeCursors.Funct1()
call getEmployeeCursors.Funct1()
call Funct1()
All produced the following error message:
ERROR at line 1:
ORA-06576: not a valid function or procedure name
How do I call Funct1()?
Thanks so much in advance,
--Anna

Hello Frank,
Thanks for the information regarding not using the system schema when creating packages.
I tried what you suggested to call the Funct1 in many ways:
SQL> mycursor := system.getEmployeeCursors.funct1;
SP2-0734: unknown command beginning "mycursor :..." - rest of line ignored.
SQL> mycursor := getEmployeeCursors.funct1;
SP2-0734: unknown command beginning "mycursor :..." - rest of line ignored.
SQL> mycursor := funct1;
SP2-0734: unknown command beginning "mycursor :..." - rest of line ignored.
SQL> select *
2 from table(system.getEmployeeCursors.funct1);
from table(system.getEmployeeCursors.funct1)
ERROR at line 2:
ORA-22905: cannot access rows from a non-nested table item
Could there be something else I need to do before making the function call?
Thanks alot!

Calling a new Browser Window from Web Dynpro Application - Empty Context

Hello,
I want to open a view in a new browser window, and followed the same way which is described in this thread:
Open view in new browser window
My first try was creating two applications, which refer to the same Component Controller. The opening of a new browser window is triggered by an action, which is called in the other application. As both applications have the same Component Controller, I thought, the context content has to be the same, but actually the context attributes are empty after opening of the new window.
In my second try I created two applications with two different Component Controllers, mapped via embedded Interface Controller. The effect is the same - I have no context content in the view.
Please, can anybody help me?
Thank you in advance.
Ilona Seifert

I done something like this:
[code]
try {
strURL =
 WDURLGenerator.getApplicationURL(
 "$PROJECT_PATH$/$PROJECT_NAME$",
 "$APPLIC_NAME$");
} catch (WDURLException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
strURL += "?par1=";
strURL += var1;
strURL += "&par2=";
strURL += var2;
strURL += "&par3=";
strURL += var3;
[/code]
and after i retrieve them:
[code]
Var1Value= WDWebContextAdapter.getWebContextAdapter().getRequestParameter("var1");
[/code]

How to call a function module dynamically?

Hi
I am doing a smartform development and here my scenario.
Scenario:
There will be a simple report which will trigger a smartform output. The report has a selection screen and and in one of the field the user will enter the layout name or the layout name will be stored in the variant so that the user need not remember the layout name.
Based on the layout selected i need to show the output.
What i have coded:
In my program after selecting the data i am calling the FM SSF_FUNCTION_MODULE_NAME which will return the function module name to be called.
Question:
How do i call the function module dynamically. I cannot do a single call to the function module using the FM name derived from the above function call. I want to make the interface calling dynamic. We dont want to hardcode the function calls coz we may have many layouts to be called so how is it possible in SAP to call the FM interface dynamically.
~Suresh

Actually you can call the FM dynamically in by taking it into one variable and than use the CALL FUNCTION V_FM_NAME.
But the problem here is, you need to take care about the importing, exporting and tables parameters. They needs to be same for all FMs which you are planning to call. Otherwise system will give you a run time error.
 CALL FUNCTION 'SSF_FUNCTION_MODULE_NAME'
 EXPORTING FORMNAME = LF_FORMNAME
* variant = ' '
* direct_call = ' '
 IMPORTING FM_NAME = LF_FM_NAME
 EXCEPTIONS NO_FORM = 1
 NO_FUNCTION_MODULE = 2
 OTHERS = 3.
 CALL FUNCTION LF_FM_NAME
 EXPORTING
 ARCHIVE_INDEX = TOA_DARA
 ARCHIVE_PARAMETERS = ARC_PARAMS
 CONTROL_PARAMETERS = LS_CONTROL_PARAM
* mail_appl_obj =
* mail_recipient = ls_recipient
 MAIL_SENDER = LS_SENDER

How to call a function module from a transformation

Hi,
Could somebody please let me know how I can call an abap function module from a transformation (abap xslt program). I know how to call the class methods from transformation, but how do i call a function module..?
Thanks,
Shashi.
Edited by: Shashi Kanth Kasam on Apr 8, 2010 12:45 PM

Ya. I can do that. But I don't want to use a class and a method to call that function module. Want to directly call function module from transformation. Is that possible..?
Thanks,
Shashi
