Local class - global class

Hi Friends,
Can a local class make friend with global class???
for example i have a local class in se38 editor and this local class should access the private attribute of global class which is there in se24.
Deepak

HI Deepak
Yo can define your ABAP Unit test class as a friend of the global class to be tested in the local class definition include of your global class. So, you have to add a line of code like
CLASS <name of global class to be tested> DEFINITION LOCAL FRIENDS <name of local ABAP Unit class> in the include where the definition of local ABAP Unit Class is in. Then you can call the private methods of your global class in the local abap unit class methods.
just refer these links

Export global classes to a local file

Hi,
is it possible to export a global class with all of its attributes, types, methods and more to a local file for archiving purposes?
We are currently using ECC 6.0, btw.

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.

Create Global Class Definition using Local Class Source Code

I would like to be able to automate the creation of global class definitions using source code that is defined in a text file (one example: convert a local class def to a global class def).
Does SAP deliver this functionality? (I'm already aware of the various classes that can be used to create global classes and how those classes can be implemented in a program to generate new classes. I'm hoping to avoid having to create a custom solution.)
Thanks in advance!

We have a winner!
Thanks Rich!
It's not a 100% solution - I was hoping to be able to generate global classes/interfaces using source code alone, without requiring user intervention.
It is however, a 90-95% solution because debugging SE24 reveals that by using a combination of the FM's SCAN_ABAP_OBJECTS_CLASSES & SEO_CLIF_MULTI_IMPORT, I should be able to quickly put together that custom application that I was trying to avoid.
I knew about the existance of SEO_CLIF_MULTI_IMPORT but I did not know about SCAN_ABAP_OBJECTS_CLASSES. I'm very happy to learn that I'm not going to have to write a parser!

Local class as a friend of a global class

Hi guys,
I'm just wondering if I could make a local class which is defined in the local section of a global class to its friend. I need this to check private attriutes and methods with abap unit.

Hi Christian,
Yo can define your ABAP Unit test class as a friend of the global class to be tested in the local class definition include of your global class. So, you have to add a line of code like

Download Global Class attributes

Hi...
I want to download the global class attributes into an excel. when i checked the menu there is no such option.. Is that possible to do.. Can anyone guide me...
Thanks in advance.
Kalpanashri Rajendran.

Hi,
Assuming you are asking specifically about the global class "Attributes" and not all information about the global class itself. To get the "Attributes" in a spreadsheet you can try this work-around:
1. Run transaction SE84 Repository Info System.
2. Expand the "Class Library" branch.
3. Double-click the "Attributes" node.
4. Enter your global class name and run the search.
5. Once the list of attributes is displayed, choose menu path System -> List -> Save -> Local File.
6. Choose "Spreadsheet" format in the popup.
7. Give a file path and name for your spreadsheet.
8. You should now have a spreadsheet with all the "Attributes" of your global class.
Best Regards,
Jamie

Using container from another global class

There are two global classes being used by me in a program - Class A and Class B.
Class A contains the container to display ALV.
Class B contains the logic to display ALV.
class B is used as attribute class in Class A.
How is that I can use the container from Class A from class B?

Like this?
class A ...
   public section.
      methods: get_container returining value(ref_cont) type ref to ...,
                      constructor.
   private section.
      data ref_container type ref to....
endclass.
class A impl...
   method get_container.
        ref_cont = me->ref_container.
   endmethod.
   method constructor.
      create object ref_container ....
   endmethod.
endclass.
class B ...
   public section.
       methods: constructor,
                      display alv.
   private section.
       data ref_alv type ref to....
       data ref_A type ref to A.
endclass.
class B impl...
   method constructor.
       data lr_container type ref to ...
       if ref_A is not bound.
            create object ref_A.
      endif.
      "get container from class A
       lr_container = ref_A->get_container( ).
       create object ref_alv
            exporting
                 container = lr_container
   endmethod.
   method display_alv.
        call method ref_alv->set_table_for_first_display...
    endmethod.
endclass.
If storing container's reference under local LR_CONTAINER in class B constructor causes not displaying ALV, you will have to store this under class B attribute. Alternative would be directly indicating the container reference as parent to ALV by calling functional method like
create object ref_alv
      exporting
           container = ref_A->get_container( )
this will however work in recent releases of SAP NW AS.

Includes in global Class

Hi all,
I have a global class (created in SE24 - Class builder) and need to use constants and types in its methods, that are defined in an include.
In functional development we just put a "INCLUDE includename." in the function group top-include.
Where can I put that include in the global class?
I tried the "local types" source file, but it doesnt accept the constant definitions inside my include.

hi, Frank Besler
If you want to add global (constant)value and type definantion, you can add them in the LXXXXTOP file, the XXXX is the function group name.
if you don't want all of the defination added only one file, you can create a file, named LXXXXFYYY, XXXX is still function group, YYY is the random string you set.
and add the 'include LXXXXFYYY' into the SAPLXXXX. (XXXX is still function group name). SAPLXXXX is the main program for the function group, you can find its name in the 'Attributes' tab 'Program name' fields in se37.
click the SAPLXXXX, you can see a example like this:
*   System-defined Include-files.                                 *
INCLUDE LATSVTOP.      " Global Data
INCLUDE LATSVUXX.      " Function Modules
*   User-defined Include-files (if necessary).                    *
* INCLUDE LATSVF...      " Subprograms
* INCLUDE LATSVO...      " PBO-Modules
* INCLUDE LATSVI...      " PAI-Modules
* add your include file here
include LATSVF01.
Please aware the your include file name can't be set random, you must follow the rule, otherwise the compile will failed.

Hello Reema,
Follow these steps :-
 Go to transaction SE24.
 Enter the name of the global class you want to create, with Y or Z at the beginning.
 Press Create pushbutton.
 A dialog window shown above will appear. Check the radiobutton : Class.
 Press Enter.
 Another dialog window shown above will appear. Enter the description for the class.
 Select from the Instantiation listbox whether you want to create the class as PUBLIC/PROTECTED/PRIVATE/ABSTRACT.
 Check the radiobutton for Usual ABAP Class.
 Check the checkbox for Final.
 Press Save pushbutton
Enter the package name or save it as Local object.
 Go to the tab-page : Methods.
 Enter the details for the method mention name, type of method(instance/static), in which visibility section the method will reside and a short description of the method.
 Check off/uncheck the checkbox to ensure that the method will be implemented
Click the pushbutton for Parameters to navigate to the screen to enter parameters for the method.
Here you can give the name of an internal table with associated type TABLE

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.

Export of global class

Hi everybody.
I want export a global class (SE24, Object Builder) to a local class in a INCLUDE, but unfortunally the Object Builder has no export function.
Does anybody know a way to change a global class to a local class?
Thx.

There's no easy way. I'm at a bit of a loss why you'd want to replace a global class witha local class that you include in your programs. What do you gain?
But if you insist, you can always cut and paste the public/private/protected sections of your class (making suitable modifications and assuming you're not on an old SAP version), and then you'd have to cut and paste the method implementations in as well.
Printing a class to a the spool is a fairly good way of getting all its details. Another alternative is to search these forums for where the includes that actually make up the class are - it should be fairly simple to write a program that would take that source code and construct local classes from it. But I still don't see the point.

can anyone plz help me out

Hi,
it looks like it's not possible to call this BAPI wihtout material number. Here is a quote from BAPI documentation.
When creating material master data, you must transfer the material
number, the material type, and the industry sector to the method. You
must also enter a material description and its language.
