Returning table in classes

Former Member — Tue, 13 May 2008 20:30:20 GMT

Hey Guys

I have created a class with two methods.

In of these methods I am trying to return a table of type VBFAVB, this is a type in se38.

Here is my method code

METHOD get_docflow_vbelv.

  DATA: t_vbfa TYPE TABLE OF vbfavb,
        l_vbfa LIKE LINE  OF t_vbfa .

  CALL FUNCTION 'WB2_VBFA_READ_WITH_VBELV'
    EXPORTING
      i_vbelv          = vbelv
    TABLES
      et_vbfa          = t_vbfa
    EXCEPTIONS
      record_not_found = 1
      OTHERS           = 2.

  IF sy-subrc = 0.
      ret_tab[] = t_vbfa[].
  ENDIF.

  CLEAR: l_vbfa,t_vbfa[].
ENDMETHOD.

And I have defined in parametrs the ret_tab like this

RET_TAB Exporting Type VBFAVB

When I compile it says 'RET_TAB' is not an internal table the specification OCCURS N is missing.

Please give me an Idea on how to "pass" an internal table in classes.

A sample code would be great !

Thanks for reading.

So how have you defined REF_TAB? Should be the same type as your itab!!

And it looks to me that you haven't?

RET_TAB Exporting Type VBFAVB, this is not an internal table.

What you can do is find out if this type also has a table type defined in data dictionary via where used list.

If not available create this table type with line type Type VBFAVB .

Alternative:

create the type in the class itself. Look at the TYPES button at the top of the screen.

ref_tab type table of VBFAVB.

at the interface you can define,

RET_TAB Exporting Type STANDARD TABLE.

Hello Sameer

On ECC 6.0 you have plenty of table types available having line type VBFAVB:

LEINT_VBFAVB_T                   Reference structures VBFAVB
LESHP_DELIVERY_DOCUMENT_FLOW_T   Delivery's Document Flow
SA_XVBFA                         Document Flow: Sales
SHP_VL10_VBFA_T                  SD Document Flow
VA_VBFAVB_T                      Table for structure VBFAVB
VBFA_SRT_T                       BAdI Interface Type for Structure VBFAVB

I would recommend to use SA_XVBFA because it is part of the rather "generic" package VA.

Your class method should look like this:


CLASS lcl_myclass DEFINITION.

  PUBLIC SECTION.

    METHODS:
      get_docflow_vbelv
        IMPORTING
          VALUE(id_vbelv)    TYPE vbeln
        RETURNING 
          VALUE(rt_data)     TYPE sa_xvbfa.

ENDCLASS.


CLASS lcl_myclass IMPLEMENTATION.

  METHOD get_docflow_vbelv.
  CALL FUNCTION 'WB2_VBFA_READ_WITH_VBELV'
    EXPORTING
      i_vbelv          = id_vbelv
    TABLES
      et_vbfa          = rt_data
    EXCEPTIONS
      record_not_found = 1
      OTHERS           = 2.
 
    IF sy-subrc = 0.
    ENDIF.
  ENDMETHOD.

ENDCLASS.


REPORT zmyreport.


DATA:  gt_vbfa   TYPE  sa_xvbfa.

PARAMETERS:
  p_vbeln            TYPE vbeln.

START-OF-SELECTION.

  CREATE go_myclass.

  gt_vbfa = go_myclass->get_docflow_vbelv( p_vbeln ).  " function call OR:
  CALL METHOD go_myclass->get_docflow
    EXPORTING
      id_vbelv = p_vbeln
    RECEIVING
      rt_data = gt_vbfa.
END-OF-SELECTION.

Regards

Uwe

Dear experts,

I have a similar problem regarding to exporting internal table in a method when I create a global class in SE24. The difference is that I have defined the internal table as Standard table of a structure. For example:

DATA: t_vbfa TYPE Standard TABLE OF vbfavb,
"assume vbfavb is a structure.                                                                                
"t_vbfa is defined in the class attribute section
METHOD get_docflow_vbelv.
    CALL FUNCTION 'WB2_VBFA_READ_WITH_VBELV'
     EXPORTING
          i_vbelv          = vbelv
     TABLES
        et_vbfa          = t_vbfa.
  
  IF sy-subrc = 0.
      ret_tab[] = t_vbfa[].
  ENDIF.
 
ENDMETHOD.

I have defined a table using the fields of vbfavb structure as ZVBFAVB, for example. I then declared an variable as follow:

RET_TAB Exporting Type ZVBFAVB

When I compiled my program, it says 'RET_TAB' is not an internal table the specification OCCURS N is missing.

How can I avoid the above problem. Where and how should I define this exporting variable RET_TAB so that I can pass this internal table out of the method.

Your help is greatly appreciated.

Thanks,

Anna

Dear experts,

Hi Anna

This what you need to do

Either look for a table type with line type VBFAVB, or create one. Table types work with classes when you are exporting tables.

I found two which are already existing and could solve your purpose.

VA_VBFAVB_T and

LEINT_VBFAVB_T.

Hope you understand.

Hi!

I have a similar issue working with a method that called a function....I have already put the returning table as you said, but it didn't work 😪, could you help me? Please

method ZGET_DETALLE. * TYPES it_detalle TYPE ty_det. DATA: t_det TYPE STANDARD TABLE OF zccdetalle, l_detalle LIKE LINE OF t_det . CALL FUNCTION 'ZF_DATOS_CLIENTE_LVAA' EXPORTING pncliente = PNCLIENTE " ELEMENTO DE LOS DATOS DEL CLIENTE IMPORTING pmensaje = PMENSAJE " ELEMENTO DE DATO PARA MENSAJE*S TABLES ptcte = t_det " ESTRUCTURA DETALLE CLIENTE . "PTDET[] = it_detalle[]. IF sy-subrc = 0. ptdet[] = t_det[]. ENDIF. CLEAR: l_detalle,t_det[]. endmethod.

In the interface

When I run the method appears this window
