Hi There,

Is there any way to take the filed name from SAP data dictionary during run-time . I mean if i will execute a TA the field name , program name (like what shows pressing F1) all the details.

Any help is appreciated.

Regards,

Khagendra

Hi Khagendra

Are you trying to dynamically determine the attributes of a field during runtime?

Have you tried using RTTS services? You can try using class CL_ABAP_TYPEDESCR. Check out the class documentation for more details.

I've just pasted the sample coding from the class documentation.


REPORT typedescr_test.

TYPES:
  my_type TYPE i.

DATA:
  my_data TYPE my_type,
  descr_ref TYPE ref to cl_abap_typedescr.

START-OF-SELECTION.
  descr_ref = cl_abap_typedescr=>describe_by_data( my_data ).

  WRITE: / 'Typename:', descr_ref->absolute_name.
  WRITE: / 'Kind :', descr_ref->type_kind.
  WRITE: / 'Length :', descr_ref->length.
  WRITE: / 'Decimals:', descr_ref->decimals.
