Field name referenced by field symbol

[Former Member]

Hi,

I would like to get the field name referenced by a field symbol at rutime. In the code below, besides the type and length of the field, I also would like to get the field names 'AA', 'BB' and 'CC' .

Can you please tell me how I can get this information?

DATA: BEGIN OF g_test,

aa(10) TYPE c,

bb TYPE i,

cc(20) TYPE c,

END OF g_test.

DATA: l_type(20),

l_len TYPE i.

FIELD-SYMBOLS <fs>.

START-OF-SELECTION.

DO 3 TIMES.

ASSIGN COMPONENT sy-index OF STRUCTURE g_test TO <fs>.

DESCRIBE FIELD <fs> TYPE l_type OUTPUT-LENGTH l_len.

WRITE: /5 sy-index, l_type, l_len.

• Would like output as:

• 1 AA C 10 instead of 1 C 10

• 2 BB I 11 instead of 2 I 11

• 3 CC C 20 instead of 3 C 20

ENDDO.

Hi,

Using your sample structure you can do it using such a code:

DATA: BEGIN OF G_TEST,
        AA(10) TYPE C,
        BB     TYPE I,
        CC(20) TYPE C,
      END OF G_TEST.

TYPE-POOLS: ABAP.

DATA: COMP TYPE LINE OF ABAP_COMPDESCR_TAB.
DATA: STRUCT_REF TYPE REF TO CL_ABAP_STRUCTDESCR.

  STRUCT_REF ?= CL_ABAP_STRUCTDESCR=>DESCRIBE_BY_DATA( G_TEST ).
  LOOP AT STRUCT_REF->COMPONENTS INTO COMP.
    WRITE:/ COMP-NAME, COMP-TYPE_KIND, COMP-LENGTH, COMP-DECIMALS.
  ENDLOOP.
