Move Corresponding

• The move-corresponding statement does the same job as move statement, but it also checks for the field names. Like if we have same field name in two different structures, it would pick up same field name and move the data accordingly.

• To perform a move from one field string to another where the data types and/or lengths do not match, use the move-corresponding statement.

• Components in the receiving field string that do not have a matching name in the sending field string are not changed.

Example:Data: begin of s1,

c1 type p decimals 2 value '1234.56',c2(3) value 'abc',c3(4) value '1234',

end of s1,begin of s2,

c1(8) ,x2(3) value 'xyz',c3 type i,

end of s2.Move-corresponding s1 to s2.write: s2-c1, s1-c2, s2-c3.

Exceptions in a function module-Exceptions are used to handle errors that occur in function modules. The calling program checks whether any errors have occurred and then takes action accordingly. In function Modules there are basically two raise statements are used: raise<exception> andMessage……….Raising<exception>

Pass the exception in Function Modules
