Do you want to get the components of a structure dynamically at run time?

1. se11 with the structure name witin DATATYPE option.

2. If you want to watch the fields within the abap editor write structure-field and double-click it.

example: write RC29P-STLKZ and doble-click it.

Hi

You can give Data Element from ABAP Dictionary as a Component Type.

You can use the RTTS for this.

type-pools: abap.

DATA: ls_components TYPE abap_compdescr.
DATA: lo_strucdescr TYPE REF TO cl_abap_structdescr.
DATA: ls_t001 TYPE t001.

lo_strucdescr ?= cl_abap_typedescr=>describe_by_data( ls_t001 ).

LOOP AT lo_strucdescr->components INTO ls_components.
  WRITE:/ ls_components-name.
ENDLOOP.

Hi,

try this code.

data:BEGIN OF str,

matnr type mara-matnr,

ersda type mara-ersda,

END OF str.

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( str ). " 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.

Hello,

Try the following code.

DATA : components LIKE rstrucinfo OCCURS 0 WITH HEADER LINE. " List of components

CALL FUNCTION 'GET_COMPONENT_LIST'

EXPORTING

program = sy-repid

fieldname = < STRUCTURE NAME >

TABLES

components = components.

The components table will return all the components of the <structure>.

Hope this will be helpful.

Regards,

Pranali
