Passing an Internal table to a "Z" class

Hi,
I am new to ABAP Objects. I am developing a "Z" class and would like to pass an internal table to this "Z" class. How do I pass it. What declarations do I need to make in the "Z" class and where?
Thanks in advance.
Mick

if you want to pass internal table, then you have to use the table types. create the Table type (you can define in Se11 or you can define your own type pool and include in the properties section )and refer it when you are defining the importing or exporting parameter.

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.

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.

Error Passing an internal table between BSP pages

Any time there is data in the internal table and I try to pass it from one BSP page to the next I get an Web error. I've heard that it is possible to pass an internal table from one page to the next. can anyone point me in the right direction here?

You can do this with the navigation object only if the table is very small. Overwise it overflows 2+KB limitation of URLs.
Alternative ideas is to use server side cookies (search forum for many examples).
If stateful, just hang stuff of your application class.

Internal table when creating a class

Hi everybody
im defining parameters when defining a class
one of the parameters is IT_MARA, of type MARA
Ive declared a method - SELECT_DATA, where the code is
SELECT * FROM MARA
INTO TABLE IT_MARA....
When activating it
Im getting the error - IT_MARA is not an internal table 'OCCURS n ' specification is missing
anybody knows how to solve that issue?

Hi Anjali,
I figure out you are having trouble passing an internal table out of a method of a class.
The error you get is because the parameter you have declared using TYPE MARA actually creates a line type and not an internal table in the signature of the method.
You have to declare the parameter with a 'table type' rather, and it will create an internal table.
You could use either a global table type or a local one.
Please have a look at the code below using a local table type for this problem:
CLASS a DEFINITION.
PUBLIC SECTION.
    TYPES ty_mara TYPE TABLE OF mara.     "Local Table Type
    METHODS meth EXPORTING et_mara TYPE ty_mara.   "This makes an internal table
ENDCLASS.
CLASS a IMPLEMENTATION.
METHOD meth.
    SELECT * FROM mara INTO TABLE et_mara UP TO 10 ROWS.
ENDMETHOD.
ENDCLASS.

CREATE OBJECT lr_a.
CALL METHOD lr_a->meth

BREAK-POINT.

Passing a internal table from method

Hi All,
 I am using Object Oriented Programming in my program.
 I want to pass a Internal Table from a method calling statement written in a start-of-selection.
 Can any one give me the syntax for
1. Declaring a method with importing parameter as internal table.
2. Syntax for Method Implementation
3. Syntax for calling the method from start-of-selection.
helpful answers are rewarded.
Regards,
Azaz Ali.

Hi,
Calling Method is similar to calling function Module.
CALL METHOD cl_gui_frontend_services=>gui_download
 exporting
 filename =
IMPORTING
 FILELENGTH =
changing
 data_tab = ( this is ur internal table name )* EXCEPTIONS
 FILE_WRITE_ERROR = 1.
In OO ABAP u avoid creating table with header line
Best way to call method is to use PATTERN Button
1) Click Pattern Button
2) Select Abap Object Pattern
3) Enter
4) Select Call Method
5) Enter instance name ( i. e used for create object ) ( No need for static method like gui_download )
6) Enter Class / Interface name
7) Enter Method Name
done.
passing value to method is similar to FM.
Creating internal table for Method
any TYPE ........SAY TY_Intern
Then Syntax Should Be
DATA : OO_INTERNAL_TABLe type table of TY_Intern.
pass this to the Method.
Hope This will solve ur problem.
Please Mark Helpful Answers

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 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....

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.

Internal table in method of class (BADI)

Hello people !!
I need to use an internal table into method of class. I don´t know very well how to use it. I know that it hasn´t a header; but I don´t know how to defined and use it.
I need to use in a method of badi.-
I will be grateful by the help that your could offer to me.-
Thank you so much,
Esther.-

Thank you for your answer.
But, I had defined as de fist item, but I had defined with a structure of dictinary.
Now, in my code, I need to deposit information to the above mentioned table. Then, when I try to accede to the fields of the estructure, when I compile it gives me the following mistake:
"ACC_DATA" is a table without a header line and therefore has no
component called "CUENTA".
I attach departs from the code:
types: es_accdata type standard table of Z_ES_ACCDATA.
data: acc_data type es_accdata.
      loop at it_mseg into r_mseg.
      si es Entrada de Mercancía
        if r_mseg-bwart = '101'.
          at first.
            acc_data-cuenta = r_mseg-sakto.
            if not r_mseg-kostl is initial.
              acc_data-centro_coste = r_mseg-kostl.
            else.
              acc_data-orden_inversion = r_mseg-aufnr.

          endat.

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.
