Name of the DDIC-Entry

Question

Hi NG,
i have one little question. Is there a function/method which delivers the DDIC-Name to a defined Structure/Workarea in a program. For example
Data: wa_struc    type adrs. 
Later in the programmflow i want to know, which DDIC-Object is behind the wa_struc.
Method/function like  ->    IN: wa_struc  out:adrs.
Sounds a little bit strange, but maybe there is one easy solution.
Thanks in advance
Thorsten

Hi Thorsten,
take class <b>CL_ABAP_STRUCTDESCR</b>
(-> look at class documentation!)
e.g. from docu
  REPORT typedescr_test.
  DATA:    descr_ref TYPE REF TO cl_abap_structdescr.
  <b>DATA: wa_struc TYPE adrs.</b>
FIELD-SYMBOLS:
    <comp_wa> TYPE abap_compdescr.
  START-OF-SELECTION.
    descr_ref ?= cl_abap_typedescr=>describe_by_data( wa_struc ).
    WRITE: / 'Typename     :', descr_ref->absolute_name color 6.
    WRITE: / 'Kind         :', descr_ref->type_kind.
    WRITE: / 'Length       :', descr_ref->length.
    WRITE: / 'Decimals     :', descr_ref->decimals.
    WRITE: / 'Struct Kind  :', descr_ref->struct_kind.
    WRITE: / 'Components'.
    WRITE: / 'Name              Kind   Length   Decimals'.
    SKIP.
    LOOP AT descr_ref->components ASSIGNING <comp_wa>.
      WRITE: / <comp_wa>-name, <comp_wa>-type_kind,
               <comp_wa>-length, <comp_wa>-decimals.
    ENDLOOP.
