Include Structure

Sometime there is a need to create structure which should have fields same as some other structure and also additional fields. Suppose we have two structures A and B. Structure A has some 10 fields and structure B needs 12 fields out of which 10 fields are same as fields of structure A.

So In this case we can include structure A in structure B using keyword include. The structure to be included can be local or a dictionary object. To include all fields from structure used including. This will create direct fields in other structure. Fields can be access directly.

EXAMPLE

REPORT ZABC.

data : begin of dept,
           deptno type i,
           dname(20) type c,
       end of dept.

data : begin of emp,
         empno type i,
         ename(20) type c.
         include structure dept. “注意这两个红点
data : addr(30) type c,
       end of emp.

emp-empno = 1.
emp-ename = ’xyz’.
emp-deptno = 10.
emp-dname = ’HR’.
emp-addr = ’hyd’.

write :/ emp-empno,
         emp-ename,
         emp-deptno,
         emp-dname,
         emp-addr.
