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.
