Declaration of Rabge table Paramater in Global class method

Hi Friends,
I have created a Global class with a method GET_DATA.
In that method,i have written the like :
select * from kna1 into table it_kna1where kunnr in S_kunnr.
But, I am getting the error with Range table S_KUNNR.
Kindly, Let me know how I should Declare S_KUNNR in parameter list of GET_DATA, what should be its associated data type?
Regards,
Xavier.p

1) Create a Public Type for ranges. You can do it in SE11 or in SE24. I generally prefer doing it in SE24.
Go to Types Tab
Declare your range type
TYPES: ty_r_kunnr type range of kna1-kunnr.
2) Use this type to declare your method's parameters:
IR_KUNNR TYPE TY_R_KUNNR
3) When calling the method you can do like:
CALL METHOD O_REF->GET_dATA
EXPORTING
IR_KUNNR = S_KUNNR[].

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.

Exporting Tables from BSP to Class Methods

Afternoon Everybody,
in true SAP OSS Message style I post this question on it's own thread to enable maximum value from the reward points.
Question:
I have a BSP, in an event in my BSP I call a method in my class.
I have mastered Exporting parameters to the methods from the BSP and Importing parameters back to the BSP from the methods, but now, I need so Export a table to the method and I don't know how to.
Also, in combination with this, when I create the method I am able to setup the importing parameters, but how can create/define the importing table ?
If this is not clear I will add more info.
Thanks for your help,
Tomas.

Tomas,
The key to problem is always to learn a few "nice" things defined in the system. So let me see. The first problem you have is that methods are declared of the form:
method <parm> <direction> TYPE [REF TO] <t>
parm = the name of the paramter
direction = IMPORTING|EXPORTING|CHANGING|RETURNING
t = type of parm
However, in this type it is not possible to write that you want "type of table". You can only use predefined types (either internal or indictionary).
Having said this, most people with extensive ABAP experience before the OO-wave, tend to use character types all the time. However, we nearly always use only type string. And exactly for this type there is a type string_table.
So the code would be:
Declaration:
method lines changing type string_table
Calling:
DATA: t TYPE string_table.
APPEND 'Hello' TO t.
APPEND 'World' TO t.
class=>method( CHANGING lines = t ).
Method Implementation:
DATA: line LIKE LINE OF lines.
LOOP AT lines INTO line.
 TRANSLATE line TO UPPER CASE.
 MODIFY lines FROM line. " write back
ENDLOOP.
Better Method Implementation (works directly on row):
FIELD-SYMBOLS: <line> LIKE LINE OF lines.
LOOP AT lines ASSIGNING <line>.
 TRANSLATE <line> TO UPPER CASE.
ENDLOOP.
These two types string and string_table goes a long way. The other two types that I often use are ihttpvnp and Tihttpvnp (table): they are good for name/value pairs of strings.
Now is the time that you should invest 30 minutes reading each time that you run into a problem. You have the framework, just check up on one aspect each time. (I usually use online help, for example to understand MODIFY for writing this text.)

Access arrayobject from class method

Hi,
Can anyone tell me how to access the variables in an object array from a static method of the same class?
In another class i create a object array
MyClass[][] myObjectArray = new MyClass[3][3]
In MyClass there is a declaration:
public int myInt = 1
and a class method:
public static myMethod(){
int intVar = "this is where i would like to read the value of myInt for each object, something like myObjectArray[0][0].myInt + myObjectArray[1][2].myInt, but it does not work"
I guess something with "this" or "super", but dont know how.
Thanks,
/Thomas

It should obviously be impossible to access any Instance
in a class-method.
You could pass it as an parameter though:
public static void myMethod(MyClass[][] myCl)

Global Class that returns an internal table

Hello,
 Is it possible to create a global class (under class builder) that returns an internal table like we used to do in a function module?
 e.g. call function '<Function module name>'
 tables = i_tab.
Thanks,
Jeffrey

Hi Jeffrey,
Yeah u can do that by specifying importing parameters
to method.You can give table type for the parameters.
Thanks&Regards,
Siri.

Passing internal table to a method of a Global Class

Hi All,
I have to pass a Select option (SO_RANGE) as a IMPORT parameter to a method of a global Class (while calling that method from a executable program).
what Reference type should I give, while defining the IMPORT parameter for that method of class.
SO_RANGE have structure of type (SIGN, OPTION, LOW and HIGH)
Regards,
Pankaj.

You first need to define a type for range.
for that goto->public section of your class and put following under TYPES
TYPES : tr_matnr type range of mara-matnr .
now you can use this tr_matnr in global class to define input parameter and in your program to define a variable .
In your program define variable as
DATA data_mat TYPE Classname=>tr_matnr
To define workarea type use following.
TYPES : t_matnr TYPE LINE OF tr_matnr .

Select option in global class

Hi,
I want to add one data dictionary field as select option in a global class. I am trying to declare as table type. But i missed out something and it is not working. Could anybody help me out in this.
Regards,
Krishna.

Hello Krishna
You may have a look at table type RSELOPTION (line type RSDSSELOPT).
Alternatively, you can use a trick to "import" select-options for a selection screen into your class:

How to give a value range in export parameter (global class)

hi all,
I have created a class-method called get_po_date. In this i had export parameter as qmfe-qmnum. If i give qmfe-qmnum in import parameter in class, i am able to give only one value at one time, but i need a range of values at a time. Instead of qmfe-qmnum in associated type, i have given 'LXHME_RANGE_C12' ( a range table for char 12 ). the thing is i wanted to select this range in select-options. but still iam getting not type compatible syntax error. can any body solve my problem,
feel free to ask if any confusion with my question.
Best Regards,
abhilash.

Hello Abhilash
Instead of using a specific range (where field LOW and HIGH are of type QMNUM) you can use a generic select option (of type RSDSSELOPT). Have a look at the following sample report ZUS_SDN_SELOPTIONS.
*& Report ZUS_SDN_SELOPTIONS
REPORT zus_sdn_seloptions.
TABLES: qmfe.
DATA:
gt_data TYPE STANDARD TABLE OF qmfe,
gt_data_x TYPE STANDARD TABLE OF qmfe,
gt_selopt TYPE rseloption, " generic table type for selopts
gs_selopt TYPE rsdsselopt.
START-OF-SELECTION.
SELECT * FROM qmfe INTO TABLE gt_data
 WHERE ( qmnum BETWEEN '000000000001' AND '000000000500' ).
gs_selopt-sign = 'I'.
gs_selopt-option = 'BT'.
gs_selopt-low = '000000000001'.
gs_selopt-high = '000000000500'.
APPEND gs_selopt TO gt_selopt.
SELECT * FROM qmfe INTO TABLE gt_data_x
 WHERE ( qmnum IN gt_selopt ).
IF ( gt_data = gt_data_x ).
 WRITE: 'Selected data are equal.'.
ELSE.
 WRITE: 'Selected data are NOT equal.'.
ENDIF.
END-OF-SELECTION.
Since RSDSSELOPT and RSELOPTION are global DDIC objects they can be used in public methods.

Uwe

Major global classes used in abap objects

Hi,
I am new to the abap objects and till now i am to understand that the role of the global classes are important in the abap object program. I had tried to search on the net but i was not able to get the desired result.
I want to know which are the major global classes which are used in the ABAP objects.
Plzz provide me guidelines for it.

Ricx,
It depends on your requirement.
For alv's we use these global classes. For Webdynpro related alv we use different global classes.
CL_GUI_ALV_GRID (List Viewer)
CL_GUI_ALV_GRID_BASE (Basis Class for ALV grid)
CL_GUI_ALV_TREE (ALV Tree Control)
CL_GUI_ALV_TREE_SIMPLE (Simple ALV Tree)
CL_ALV_TABLE_CREATE (Dynamic Creation of ALV Data Table)

How to use global classes and display returned data?

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.

Best practice for selection-screen in global classes

Hello everyone,
I have build several selection screens (overall 150+ select options / parameters) some time ago and want to reuse some of them within a global class encapsulating a ALV grid. Is there an easy way to forward the values of a selection screen into my class?
I have thought of a function module (in the function group which contains the dynpros) to extract the values. Is this a state-of-the-art approach?
Thanks in advance,
Alej

Hi Uwe,
correct me if I'm wrong: I remember RS_REFRESH_FROM_SELECTOPTIONS not doing the job perfectly, what ever it was, maybe
'RS_REFRESH_FROM_SELECTOPTIONS' reads only the main selection screen of a report; it will not give you SELECTION-SCREEN BEGIN OF SCREEN ... contents.
At least it is good for extracting the names of all SELECT-OPTIONS and PARAMETERS. Then use a dynamic assign like
data:
lv_assign type string
field-symbols:
<selopt> type table.
CONCATENATE '('IM_CALLING_PROGRAM')' SELNAME INTO lv_assign.
assign (lv_assign) to <selopt>.
This not only enables you to use but also to modify the select-options on the screen as you want or need.
I know since 10 or more years SAP warns to use the dynamic ASSIGN. But it works perfectly and will probably never be changed.
Regards,
Clemens
