what do you need? a Function module that retreive you the field name and field info of a structure?

if yes, so use take a look at FM 'DDIF_NAMETAB_GET'.

Here is a code sample which illistrates the retrieval of certain data of a structure. Implement this program, enter the structure name in the selection screen and hit execute.



report zrich_0002.


type-pools : abap.

data : it_details type abap_compdescr_tab,
       wa_details type abap_compdescr.

parameters: p_type(10) type c.

data : ref_descr type ref to cl_abap_structdescr.

ref_descr ?= cl_abap_typedescr=>describe_by_name( p_type ).
it_details[] = ref_descr->components[].


loop at it_details into wa_details.
  write:/ wa_details-name, wa_details-type_kind, wa_details-length,
wa_details-decimals.

endloop.

Regards,

Rich Heilman

Hi Madhu,

try this


DATA: lr_structdescr TYPE REF TO cl_abap_structdescr,
      lv_structname  TYPE abap_typename VALUE 'YOURSTRUCT'
FIELD-SYMBOLS:
      <f_comp>       TYPE abap_compdescr.

lr_structdescr ?= cl_abap_typedescr=>describe_by_name( lv_structname ).

LOOP AT lr_structdescr->components ASSIGNING <f_comp>.
  WRITE: / <f_comp>-name, <f_comp>-length.
ENDLOOP.

Hi,

For technical settings, you can find info in table DD09L ( FM 'DD_GET_STORAGE_CLASS' ).
