ABAP OO: how to pass a internal table with objects as a method parameter

Hello all,
I have a class "ZCL_VEHICLE", this class contains the attribute WHEELS.
This attribute contains objects of the class ZCL_WHEEL.
(definition: data WHEELS TYPE TABLE OF REF TO zcl_wheel.).
I now need a method that gives this table back (as return or export parameter). How can I define a parameter for this method that will contain this table?
Thanks for the help.
Best regards,
Wim

Hi Wim
Excuse me! I understood you wanted to define it in a program, not in a class.
You can define your type into CLASS (use the same statament: go to TYPES (there's a pushbotton on status gui).
TYPES: MY_WHEELS TYPE TABLE OF REF TO .....
Now you can use this type to create a parameter like that, but you can use that type for an object of class defined as PRIVATE.
Infact if your object is public, you'll use it in a your program, so you'll probably have to define a variable like the type defined in the class.
It shouldn't make sense to define the same type for two times or more (one in the class, the others in each program uses your class). So you should define your type in dictionary (all abap object could use it).
If you think to have to use your class in few program (perhaps in olny one), you shuold consider to create your class as local class.

Passing an internal table WITH HEADER LINE to abap object

Hi. In another thread, it was explained how to pass an internal table to an abap object method. Is it possible to pass an internal table that has a header line, and RETAIN the header line once the table has been passed?
My problem is, that I can pass the table, update it, but the read buffer is not populated when returning from the object's method. This is the result of being able to pass a STANDARD TABLE type, but not a STANDARD TABLE WITH HEADER LINE.
This means that I have to read the table into a work area instead of doing a READ TABLE LKNA1 within the method, which is what I need to do.
Thanks.

Please check this sample program, notice that it is modifing the internal table and passing it back modified as well as passing the "work area" or "header line" back thru the exporting parameter.

How to pass the internal table defined in program to ALV

Hi Friends,
I have a doubt regaring the ALV's,
How can we pass the internal table defined in the program to ALV by not filling the attribute (I_STRUCTURE_NAME) in the REUSE_ALV_LIST_DISPLAY.
I have tried many ways but unable to pass the structure of the internal table. I am getting the error message "Field Catalog Not Specified......" and its terminating and when i am giving the I_STRUCTURE_NAME = 'INTERNAL-TABLE-NAME' then its displaying a blank screen with all the tool-bars and icons...(No output of internal table data is seen on the screen) .
and when i am passing the DDIC table or structure ( for eg. LFA1) to I_STRUCTURE_NAME then its displaying with any error.
Plaese help in resolving this problem....

How do I define the internal table in the smartform to get the values printed in the smartform?.
<REMOVED BY MODERATOR>
Thanks,
Edited by: Alvaro Tejada Galindo on Apr 21, 2008 1:01 PM

Nehal,
Thanks for quick response.
In the smartform under the Form Interface->Tables tab
I had defined
LT_PRDLBL LIKE ZPRDLBL. If I define TYPE instead of LIKE I get the error message saying "FLAT TYPES may only be referenced using LIKE for table parameters".
In the main window I have created LOOP, in which I have ticked the internal table and
LT_PRDLBL INTO LT_PRDLBL. In the text node I am passing the values of this internal table
&LT_PRDLBL-XXXX&.
I am able to get the print but the data is not printing.
Please help me with this.
Thanks,

How to Pass the Internal table of a report to Smart Form

Hi Experts,
I have one report in which from selection screen i am getting the values from the users, and upon that values i am filling data in to the internal table.
Now i want to pass that internal table data to the smart form
and print that data in the smart form.
So could you pls give me some pseudo code or any steps to achieve it.
Thanks & Regards,
DS

Hi DS,
First of all you need to create a SF and then need to call the FM generated by the FM in your report.
In the SF in the form interface>tables tab>mention the name of the table and its type structure.
Pls note that a new structure has to be created as the same type of your internal table which holds the data.
And the import and export parameters as just the same as in a FM.
Now after you create and activate your SF a FM will be generated (wen u execute your SF you will be taken to this SE37 screen with the name of FM so no probs..)
You can call this FM in your report. Hope this helps.
Ex:
say itab has your final data, and you also want to export a variable var1 to the SF.
after your normal report operations end, call the FM and pass on these data.
say your FM name is FM1.
call function FM1
exporting
var1 = var1
tables
itab1 = itab1.
pls note that in the SF also i gave the same names, it is not mandatory to give the same names.
and as you want to print a table in the smartforms, you need to create a table in the smart forms and then display the data which is quite simple.
Hope this helps...
if you need any further explanations, pls revert...

Narendra.

How to pass a internal table used in one method to another method in a view

hi all,
Is it possible to pass a internal table from one method to another method in a view??
If so , kindly help me.

Hi Bala,
If you want to pass this internal table between different methods of the same view then write the contents of this internal table to a context node of your view using BIND_TABLE. You can then read the contents of this internal table from the other method using the reference of that node & the GET_STATIC_ATTRIBUTES_TABLE method.
However if you want to pass the internal table between methods of different views then create a context node at the COMPONENTCONTROLLER level & then do a context mapping of this node to your local views context in both your views. You can follow the same BIND_TABLE & GET_STATIC_ATTRIBUTES_TABLE methods approach.

How to return an internal table with methods ?

Hi,
I am an Java programmer and very new to ABAP.
How do I return a internal table with a method? I have the table GP1_PRODUCTS and want to return a copy of this table as an internal table called PRODUCTS.
Here is my code that does not work:
class PRODUCTS definition
public
final
create public .
public section.
*"* public components of class PRODUCTS
*"* do not include other source files here!!!
methods GET_PRODUCT_LIST
 returning
 value(PRODUCTS) type GP1_PRODUCTS .
protected section.
*"* protected components of class PRODUCTS
*"* do not include other source files here!!!
private section.
*"* private components of class PRODUCTS
*"* do not include other source files here!!!
ENDCLASS.
CLASS PRODUCTS IMPLEMENTATION.
* <SIGNATURE>---------------------------------------------------------------------------------------+
* | Instance Public Method PRODUCTS->GET_PRODUCT_LIST
* +-------------------------------------------------------------------------------------------------+
* | [<-()] PRODUCTS TYPE GP1_PRODUCTS
* +--------------------------------------------------------------------------------------</SIGNATURE>
method GET_PRODUCT_LIST.
DATA: it_products TYPE STANDARD TABLE OF GP1_PRODUCTS.
select * from GP1_PRODUCTS into table it_products.
PRODUCTS = it_products.
endmethod.
ENDCLASS.

You have to create a table type for your table GP1_PRODUCTS.
If you use global class (created in SE24), than:
Create a Table Type in SE11
Go to SE11, Enter a name like ZPRODUCTS in the Data Type
There will be popup when you press the Create button to decide a type. Select the Table Type
Enter GP1_PRODUCTS in the Line Type.
* method declaration
methods GET_PRODUCT_LIST
 returning
 value(PRODUCTS) type ZPRODUCTS.
If you use local class:
TYPES: ty_products type standard table of GP1_PRODUCTS..
* method declaration
methods GET_PRODUCT_LIST
 returning
 value(PRODUCTS) type ty_products

Pass the internal table with different structures to the class module

Hi ,
I have created a class method to fill up the data in XML format. the method can be called from various programs with internal table with different structures. I want to pass it as dynamic How can I do that.
I tried to declare that as type any.
but not working.
regards,
Madhuri

Hi,
You could work with data reference.
Use GET REFERENCE OF itab INTO data_ref for passing the internal table to your method, and dereference it within the method with ASSIGN statement...
DATA: lr_data TYPE REF TO data.
GET REFERENCE OF itab INTO lr_data.
CALL METHOD meth EXPORTING pr_data = lr_data.
METHOD meth.
FIELD-SYMBOLS <fs> TYPE ANY TABLE
ASSIGN pr_data->* TO <fs>.
ENDMETHOD.

How to create an internal table with a types structure?

Hi experts,
I've 3 internal tables with the same structure, I think I could put a type structure and put that type inside the body of the internal data, is this possible? If true, how can I put that?
Example:
TYPES: Begin of type_s,
               pernr like pa0001-pernr,
             end of type_s.
Data: begin of itab_1 occurs 0,
¿¿¿??? reference to type_s
         end of itab_1.
Thanks a lot,
Regards,
Rebeca

Hi,
Use like this..
DATA: Begin of type_s,
pernr like pa0001-pernr,
end of type_s.
DATA: BEGIN OF ITAB_1 OCCURS 0.
INCLUDE STRUCTURE type_s.
DATA: END OF ITAB_1.
Otherwise like this.
types: Begin of type_s,
pernr like pa0001-pernr,
end of type_s.
Data: itab_1 type standard table of type_s.
Note: You have to create work area explicitly.
Like this
data wa like itab1.

How to sort an internal table with a header line?

hi all,
i have declared table i_bseg type standard table of bseg with header line.
now i have populated data in i_bseg.
now i am sorting it by bukrs
ie i am writing sort i_bseg by bukrs.
before sorting all i_bseg-belnrs were populated...
but after sorting the contents of the i_bseg is changing.
some of the belnrs are getting deleted..
is there any special way to sort an internal table with header line...?

hi,
SORT <itab> [ASCENDING|DESCENDING] [AS TEXT] [STABLE].
The statement sorts the internal table <itab> in ascending order by its key. The statement always applies to the table itself, not to the header line.
If you have an internal table with a structured line type that you want sort by a different key, you can specify the key in the SORT statement:
SORT <itab> [ASCENDING|DESCENDING] [AS TEXT] [STABLE]
BY <f1> [ASCENDING|DESCENDING] [AS TEXT]
<fn> [ASCENDING|DESCENDING] [AS TEXT].
this is your sort statement: sort i_bseg by bukrs.
you try with this statement: sort i_bseg by bukrs STABLE.

How to Pass the internal table data?

DearAll,
How to pass the Data of one internal table on a 1.html page to another html page for output, in BSP Application.
regards.

Hi ,
In the onInputProcessing event of the first page , write the following code...
call method NAVIGATION->SET_PARAMETER exporting
    name = 'it_filt_cur'
    value = it_filt_cur.
Here it_filt_cur is internal table.
          NAVIGATION->GOTO_PAGE('next.htm').
In the next page , you can make the internal table as auto in the attributes.
Since you have made the itab as auto transfer , you can directly access the itab in the initialization event of the next page if it is stateless.
