Dynamic perform

Former Member — Wed, 21 Apr 2010 09:01:52 GMT

Dear all,

I wanted to create a dynamic perform. Here I will show u an example



...
      PERFORM get_correct_umlaut TABLES lt_bkpf.
....
      PERFORM get_correct_umlaut TABLES lt_bseg.
....
      PERFORM get_correct_umlaut TABLES lt_vbak.

.....
.....
.....

form get_correct_umlaut TABLES pt_any_table TYPE ANY TABLE.


endform.                    " get_correct_umlaut

I have a syntax error. What is the right way to define a dynamic PERFORM like this???

Hi,

to avoid syntax error, you should use :


FORM form_name TABLES tab_name TYPE table.
...
ENDFORM.

Depending what you want to do in this FORM you can eg. declare the field-symbols of type any, and loop through the table tab_name assigning this field-symbol and process it.

Write sth more what you would like to achieve through this procedure.

Regards,

Hi,

thank u very much for this information. I will make a dynamic perform. This mean I want to loop to any tables, which comes throw this perform. For example


Field-symbols:  <ft_any_table> type any table.

FORM form_name TABLES tab_name TYPE <ft_any_table>.

 assign component tab_name of structure <fs_any_struc>.

  loop at tab_name ASSIGNING  <fs_any_struc>.
   endloop.

ENDFORM.

Compiler say <ft_any_table>. is unknown. Do you know now what I want to do?

Simply skipp the typing for table at all


FORM form_name TABLES tab_name.  "now tab_name is generic one (you can pass any table)
 
ENDFORM.

Hi,


Field-symbols:  <ft_any_table> type standard  table."Instead of any table Use standard table Because Tables parameter only                                                                                
" support Standard table 
 
FORM form_name TABLES tab_name LIKE <ft_any_table>. " Use LIKE Key word
 
 assign component tab_name of structure <fs_any_struc>.
 
  loop at tab_name ASSIGNING  <fs_any_struc>.
   endloop.
 
ENDFORM

Hi,

According to what you wrote, I suppose you want to achieve only quasi-dynamic procedure, since you are differentiating the type with case in your Form..

Thus, I think that following approach will satisfy your requirements:


  DATA: it_mseg TYPE TABLE OF mseg,
        it_mkpf TYPE TABLE OF mkpf.

  SELECT *
    FROM mseg
    INTO TABLE it_mseg
    UP TO 100 ROWS.

  SELECT *
    FROM mkpf
    INTO TABLE it_mkpf
    UP TO 90 ROWS.

  PERFORM do_sth TABLES it_mseg.
  PERFORM do_sth TABLES it_mkpf.

*&---------------------------------------------------------------------*
*&      Form  DO_STH
*&---------------------------------------------------------------------*
FORM do_sth  TABLES   local_itab TYPE table.

  DATA: r_type TYPE REF TO cl_abap_structdescr,
        type_name TYPE string.

  FIELD-SYMBOLS: <mseg> TYPE mseg,
                 <mkpf> TYPE mkpf.

  r_type ?= cl_abap_typedescr=>describe_by_data( local_itab ).
  CALL METHOD r_type->get_relative_name
    RECEIVING  p_relative_name = type_name.

  CASE type_name.
    WHEN 'MKPF'.
      LOOP AT local_itab ASSIGNING <mkpf>.
        IF <mkpf>-budat EQ '20090101'. "just an example
*         some calculations...           
        ENDIF.
      ENDLOOP.
    WHEN 'MSEG'.
      LOOP AT local_itab ASSIGNING <mseg>.
        IF <mseg>-menge GT '1000'. "just an example
*         some calculations...           
        ENDIF.
      ENDLOOP.
    WHEN OTHERS.
* skip
  ENDCASE.

ENDFORM.                    " DO_STH
