How to get structure component name?

MarcinPciak — Fri, 31 Aug 2007 12:34:19 GMT

Hi,

This is my code:

data: wa_outtab type t_mytype.

field-symbols <fs_componet> type any.

do.

assign component sy-index

of structure wa_outtab to <fs_component>

if sy-subrc <> 0.

exit.

endif.

write / <fs_component>.

enddo.

My question is. How can I display name of <fs_component> it is pointing to (names of the fields in wa_outtab instead of its values)?

Please help.

HI,

do like this.

DATA: lr_rtti_struc TYPE REF TO cl_abap_structdescr.

DATA: lt_comp TYPE cl_abap_structdescr=>component_table.

DATA: ls_comp LIKE LINE OF lt_comp.

lr_rtti_struc ?= cl_abap_structdescr=>describe_by_data( <b>wa_outtab</b> ). " Get the description of the data

lt_comp = lr_rtti_struc->get_components( ). "Get the fields of the structure

loop at lt_comp into ls_comp.

WRITE:/ ls_comp-name. " Write the column names

endloop.

<b>reward if helpful</b>

rgds,

bharat.

Hello Marcin

You could try the following coding:

  DATA:
    ld_name           TYPE string,
    ldo_data           TYPE REF TO data,
    lo_typedescr     TYPE REF TO cl_abap_typedescr.


  GET REFERENCE OF <fs_component> INTO ldo_data.
  lo_typedescr = CL_ABAP_TYPEDESCR=>DESCRIBE_BY_DATA_REF( ldo_data ).

  ld_name = lo_typedescr->get_relative_name( ).
" Perhaps other methods of CL_ABAP_TYPEDESCR are more useful...

Regards

Uwe
