Pass the structure name and return the description fields.

Hi experts!!,

I would like to know a class and the method that I pass the structure name and return all the description fields.

Thanks a lot

Hello Ana

Have a look at class CL_ABAP_STRUCTDESCR.

DATA: ls_knb1   TYPE knb1.
DATA: lo_typedescr    TYPE REF TO cl_abap_typedescr.
DATA: lo_strucdescr   TYPE REF TO cl_abap_structdescr.
DATA: lt_dfies            TYPE ddfields.


lo_typedescr = cl_abap_structdescr=>describe_by_data( ls_knb1 ).
lo_structdescr ?= lo_typedescr.

lt_dfies = lo_structdescr->get_ddic_field_list( ).
" Or check public attribute: lo_structdescr->components   for non-DDIC structures

Other useful RTTI classes are:

CL_ABAP_DATADESCR

CL_ABAP_TYPEDESCR

CL_ABAP_TABLEDESCR

CL_ABAP_CLASSDESCR

Hi Ana,

alternatively, you can go directly in table DD03M, according you've set a data element for each of your structure fields, and not have used Predefined Type.

I do it with this function

CALL FUNCTION 'DDIF_FIELDINFO_GET'

EXPORTING

TABNAME = STR

LANGU = SY-LANGU

TABLES

DFIES_TAB = IT_TEXTOS.

Thanks!!
