How to use global classes and display returned data?

Hello experts,
I have the following code in a program which accesses a global class (found in the class library). It executes one it's static methods. What I would like to do is to get hold of some elements of the returned data. How do I do that please?
Your help is greatly appreciated.
***Use global class CL_ISU_CUSTOMER_CONTACT
DATA: o_ref TYPE REF TO CL_ISU_CUSTOMER_CONTACT.
DATA: dref_tab LIKE TABLE OF O_ref.

P_INSTANCES TYPE string,

P_NOTICE TYPE EENOT_NOTICE_AUTO,
P_OBJECTS TYPE BAPIBCONTACT_OBJECT_TAB,

end of o_ref2.
TRY.

 EXPORTING
 X_CONTACTID = '000001114875' "Whatever value here
 RECEIVING
 Y_CONTACTLOG = o_ref
ENDTRY.
WHAT I WOULD LIKE TO DO IS TO MOVE o_ref TO o_ref2 and then display:
1) P_DATA-PARTNER
2) P_DATA-ALTPARTNER
How can I do this please?

I now have the following code. But when I check for syntax I get different error. They are at the end of the list.
Here is the code the way it stands now:
================================================
***Use global class CL_ISU_CUSTOMER_CONTACT

*use <wa_orfe2> to transfer into oref2.
endloop.
write: / 'hello'.
=========================================
Here are the errors I get:
The field "DREF" is unknown, but there is a field with the similar name "OREF" . . . .
When I replace itr by OREF I get:
"OREF" is not a data reference variable.
I then try to change it to dref_tab. I get:
"DREF_TAB" is not a data reference variable.
Any idea? By the way, must there be a HANDLE event for this to work?
Thanks for your help.

Dump error after calling a global class from se24

this is the small code i did so far.
parameters: X type i,
                  Y type i.
data: Z type i.
data: con1 type ref to ZTEST1.
CALL METHOD con1->zm1
EXPORTING
    a      = x
    b      = y
IMPORTING
    c      = z.
write:/ z.
after executing iam getting a dump error-
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
caught and
therefore caused a runtime error.
The reason for the exception is:
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component (variable: "CON1").
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.

Hi, Could you please tell me how to solve this issue?

Access global data of report in global class methods?

Hi all,
I have defined one global class in SE24 and i am using methods of this class in report program.
Can i access global data of my report program in class methods directly without declaring it as IMPORT
parameter?
Thanks,
Apita

Hi,
Well, now you did confuse me: first you asked about using global data of a report program in global class (created in SE24), and the answer is: no, you can't directly access the global data of another program in a method of global class (yes, you should pass them via importing parameters), and you shouldn't even consider using indirect means of doing so via special form of ASSIGN statement reserved for internal use by SAP. The ASSIGN will not work if someone reuses the global class elsewhere in the system without loading your report. Don't ever program such atrocious dependencies in global class...
And now you ask about the use "in method implementation in report program"..? Just to be sure - you can't program the implementation of a global class method in a report program.
You can program a local class inheriting from a global class and redefine/re-implement methods of such global super-class in a report program. Global data of report program, including the selection screen, would be directly accessible to such local class. It would still not be a good idea to use this access:
Conversely, within an encapsulated unit, that is, within a class, you should avoid accessing more global data directly. Within methods, you should generally modify attributes of the class only. Write access to global data outside the class is not recommended. Accessing data in this way should only be done using specially marked methods, if at all. The use of methods of a class should not evoke any side effects outside the class itself.

Very Urgent: how to define field symbols in class using se24 Points assured

hi all
I am new to abap oo programming. I am using se24 to build a class
where some methods have code which involves working with field sybmols but i am not able to figure out way for how to define field symbols in the attributes section.
I tried defining like : fld_sym type ref to dbtab-fld
but in the method implementation if i try to use it like assign fld to <fld_sym> there it says fld_sym is not defined as a field symbol.
So can anyone please guide me how to define field symbols in se24.
Also what should be the general steps while creating a class using se24.
Points assured
thanks

Hi
Global classes are like Global fun modules in which the Methods and code is already written and is mainly used for Reusability purpose.
Goto SE24 tcode and see the std global classes like

How to use abap memory in global class

Hi experts,
I want to know how to use abap memory in global class. when i try write export and import statement its showing
error is export statement does not support in object oriented concept.
Thanks
Ramesh Manoharan

Hi Ramesh,
Export and import statements were not allowed to use in classes. Create a global variable in public section of that class of type of export parameter.Then pass value to the global variable of class by calling that class.

How to export local class to global class in abap ?

is there any report that can export local class to a global class ?
thanks !

Hi,
you can go to SE24 and there you can create a new class with reference to the class already created and your new class will have the same properties as your local class.

SE24 Global class transportation failed

Hi,
I have created one global class with two methods in it (Development server). When i checked the syntax errors in these methods there are no errors. But when i transported this global class to quality system, the transportaion failed and when i checked the syntax errors of these methods in quality system , it is giving one error saying that 'include report 'zcl_pricing============cl' not found.
this zcl_pricing is the global class created in development server.

are you sure that class and methods are in same transport? Check object entry.
If class and method are in same transport, go to quality system (SE24) and check if class is available. Maybe all you have to do is activate it in quality system.

How to assign the events in a specific method in class builder(se24)

i have declared one event in event part.i want to asign the event to one method .can any one help me .i have to do it in se24.pls

hi,
create a class in se24.
click the EVENTS tab, define an event.
click the METHODS tab, define a method to trigger/ raise the event
define one more method as an event handler method for the event.
for a method to be an event handler, click on the detail view,
select the check box Event Handler for give the classname where the event is defined and the event name, click on Change button.
event can be in the same class or different from that of the event handler method.
don't forget to register the event handler method in the program.
click the code button of ur trigger method(meth2 in my example) and write there,
raise event evt1.
now your class is ready.
now in se38 program,
declare a reference variable to ur class,
create an object,set the handler for ur event,
call the trigger method
data:oref type ref to zsowcl1.
create object oref.
set handler oref->meth1 for oref. handler method
call method oref->meth2. raise evnt method
hope it gives you clear idea,

SELECT-OPTIONS in global class definitions

I'd like to 'type' selection ranges inside a global class created with SE24.
For example:
The data element PRODH_D (Product hierarchy) has no range structure or range table in SE11.
Before I go to the trouble of defining the structure and table type in SE11, I'd like to define them in my global class and then use the 'type' for selection parameters.
For example:
types: begin of ty_kunnr_select,
         sign(1)    type c,
         option(2) type c,
         low        type kunnr,
         high       type kunnr,
       end of ty_kunnr_select.
data: st_kunnr_range type ty_kunnr_select.
data: ta_kunnr_range type standard table of ty_kunnr_select.
I've tried entering the code in multiple areas of the global class. I can get the code to compile just fine. But, when I try to use the type with a parameter definition of a method it won't compile.
Does anyone know how to do this?

Hi,
Create a TYPE-POOL and store in it your global fields. At your "Properties" screen(SE24) add your type pool. Then you can use your types.

Calling Instance Method in a Global Class

Hi All,
Please can you tell me how to call a instance method created in a global class in different program.
This is the code which I have written,
data: g_cl type ref to <global class>.
call method g_cl -> <method name>
I am not able to create Create object <object>.
It is throwing the error message " Instance class cannot be called outside...."
Please can anybody help me..
*Text deleted by moderator*
Thanks
Sushmitha

Hi susmitha,
1.
data: g_cl type ref to <global class>.
2.
Create object <object>.
3.
call method g_cl -> <method name>.
if still you are getting error.
then first check that method level and visibility in se24.
1.if level is static you can not call it threw object.
2. if visibility is protected or private then you can not call it directly.
If still you are facing same problem please paste the in this thread so that i can help you better.
