Hi,
Here is the code sample to see the table and its field.If you double click the table name,then you can go to SE11 and see the field descriptions from the program itself.Kindly reward points if it is useful.
TABLES: DD02L,
        DD02T,
        DD03L,
        DD04T.
DATA: BEGIN OF ITAB_TABLES OCCURS 0,
          TABNAME LIKE DD02L-TABNAME,
      END OF ITAB_TABLES.
DATA: FILEOPENCANCELLED.
SELECTION-SCREEN: COMMENT 1(80) TEXT-001, SKIP 1,
                  COMMENT 1(80) TEXT-002, SKIP 1.
PARAMETER: TBLNAME LIKE DD02L-TABNAME.
IF TBLNAME IS INITIAL.
  CALL FUNCTION 'UPLOAD'
       EXPORTING
            FILENAME = 'tablenames.txt'
       IMPORTING
            CANCEL   = FILEOPENCANCELLED
       TABLES
            DATA_TAB = ITAB_TABLES.
  IF NOT FILEOPENCANCELLED IS INITIAL.
    EXIT.
  ENDIF.
ELSE.
  CLEAR ITAB_TABLES. REFRESH ITAB_TABLES.
  ITAB_TABLES-TABNAME = TBLNAME.
  APPEND ITAB_TABLES.
ENDIF.
SORT ITAB_TABLES.
DELETE ADJACENT DUPLICATES FROM ITAB_TABLES.
TRANSLATE ITAB_TABLES-TABNAME TO UPPER CASE.
SELECT TABNAME DDTEXT FROM DD02T
       INTO CORRESPONDING FIELDS OF DD02T
       FOR ALL ENTRIES IN ITAB_TABLES
       WHERE TABNAME = ITAB_TABLES-TABNAME AND
             DDLANGUAGE = 'E'.
  FORMAT COLOR COL_KEY.
  WRITE: / 'N ' AS SYMBOL,
                DD02T-TABNAME RIGHT-JUSTIFIED, '-', DD02T-DDTEXT,
           '? ' AS SYMBOL.
  HIDE DD02T-TABNAME.
  FORMAT COLOR OFF.
  SELECT FIELDNAME ROLLNAME DATATYPE LENG DOMNAME FROM DD03L
         INTO CORRESPONDING FIELDS OF DD03L
         WHERE TABNAME = DD02T-TABNAME.
    SELECT DDTEXT FROM DD04T
           INTO CORRESPONDING FIELDS OF DD04T
           WHERE ROLLNAME = DD03L-ROLLNAME AND
                 DDLANGUAGE = 'E'.
      WRITE: /
            DD03L-FIELDNAME, DD03L-ROLLNAME,
            DD03L-DATATYPE, DD03L-LENG NO-ZERO,
            DD03L-DOMNAME, (35) DD04T-DDTEXT.
    ENDSELECT.
  ENDSELECT.
  ULINE.
ENDSELECT.
CLEAR DD02T-TABNAME.
AT LINE-SELECTION.
  IF NOT DD02T-TABNAME IS INITIAL.
    call function 'RS_DD_DEF_SHOW'
        EXPORTING
            OBJNAME              = DD02T-TABNAME.
  ENDIF.
  CLEAR DD02T-TABNAME.
