Exporting table from methode

Former Member — Wed, 21 Apr 2010 08:26:27 GMT

Hi experts,

how can I handle it to exporting a table from a structure from a methode?

At the moment I export the structure in the methode but I need to export a table.

At the moment:

Parameter Type Typing Methode Associated Type

param_1 Exporting Type structure

I need something like that:

Parameter Type Typing Methode Associated Type

param_1 Exporting Type Table of structure

... but that is not possible

Hi,

just define a table-type for your structure in the datadictionary and use it in your method.

Otherwise you could use the return type "table" and create a dynamic table based on your

structure in the method.

There is no Return Type "Table". Only Type: "Importing", "Exporting", "Changing" and "Returning" and as Typing Method only "Like", "Type" and "Type Ref To" ?

DSP is right.

All you need is:

- go to ABAP Dictionary and create table type using structure you have as its line type

- then in your method use exporting parameter, give type as typeing method and table_type you just created as the type itself

You should then be able to export object which is typed as a table, having a line typed as the structure you need.

I think he meant something like this


CLASS lcl_test DEFINITION.
  PUBLIC SECTION.
    CLASS-METHODS: get_tab EXPORTING gen_table TYPE table.
ENDCLASS.                   


CLASS lcl_test IMPLEMENTATION.
  METHOD get_tab.

    SELECT * FROM sflight INTO TABLE gen_table UP TO 10 ROWS.
  ENDMETHOD.                    
ENDCLASS.                    

START-OF-SELECTION.
  DATA: it_sflight TYPE TABLE OF sflight.

  lcl_test=>get_tab( IMPORTING gen_table = it_sflight ).
  "here IT_SFLIGHT holds what you want

Of course you could make it more generic, meaning query dynamic DB table inside get_tab and create dynamic table outside the method call to get returned data to that table. But basically it shows the idea.
