DATA: BEGIN OF struc2,

        a    TYPE d,

        b    TYPE t,

        BEGIN OF struc3,

上面的嵌套结构可以这样使用：

struc2-struc3-d = 'AABB'.

WRITE: struc2-struc3-d .

如果是使用TYPES定义的嵌套的结构也可以这样访问：

TYPES: BEGIN OF struc2,

        a    TYPE d,

        b    TYPE t,

        BEGIN OF struc3,

          c    TYPE f,

          d(2) TYPE x,

        END OF struc3,

        e(4) TYPE x,

        f(8) TYPE c,

      END OF struc2.

DATA: struc1 TYPE struc2.

struc1-struc3-d = 'AABB'.

WRITE: struc1-struc3-d .
