Using field symbol on export parameter

[Former Member]

HI All,

I am using this logic In few methods of mine and I wonder if there is option the create one method

and every time that I need it just call it.

The issue is that <lt_output> is not assign yet (this need to happen in the method itself )so And I need to export it

and if I am creating method with exporting field type any I put the field symbol there I am getting dump.

Any idea ?

ASSIGN COMPONENT lv_table_out
            OF STRUCTURE is_response TO <lt_output>.
  IF sy-subrc <> 0.
    READ TABLE it_map INTO ls_map INDEX 1.
    lv_out = ls_map-left.
    ASSIGN COMPONENT lv_out
    OF STRUCTURE is_response TO <lt_output>.
  ENDIF.

Best regards

Hi,

did you try to create a macro (local or in db table TRMAC) ?

HI Klaus,

I think that Macro is obsolete ..

In OO

Hi Joy,

Why would you need to export a field symbol that is not assigned yet?

In my opinion only the component name (lv_table_out) and structure name (is_response) have to be passed...

HI Manu,

The issue is that the the only thing that I need to use after i call to this method is <lt_output> ...

Thanks,

Hi,

Ok, then you will have to use a data object to reference your field symbol and use a returning parameter I guess:

DATA: lo_data TYPE REF TO data.
FIELD-SYMBOLS: <lt_output> TYPE ANY.

CLASS lcl_main DEFINITION.
  PUBLIC SECTION.
    CLASS-METHODS: get RETURNING value(r_val) TYPE REF TO data.
ENDCLASS.                    

CLASS lcl_main IMPLEMENTATION.
  METHOD get.
    FIELD-SYMBOLS <fs> TYPE ANY.
    ASSIGN COMPONENT 1 OF STRUCTURE is_response TO <fs>.
    GET REFERENCE OF <fs> INTO r_val.
  ENDMETHOD.                    "get
ENDCLASS.                   
 
START-OF-SELECTION.

  lo_data = lcl_main=>get( ).       
  ASSIGN lo_data->* TO <lt_output>.  

Kr,

m.
