Cannot Use NON-LOCAL Addition

You cannot use the NON-LOCAL addition to the DATA ,
STATICS , or CONSTANTS statements in ABAP Objects.

In ABAP Objects, the following statements cause a syntax error:

METHOD|FUNCTION|FORM ...
DATA f TYPE ... NON-LOCAL.
...
ENDMETHOD|ENDFUNCTION|ENDFORM.

Correct syntax:

DATA f TYPE ...

METHOD|FUNCTION|FORM ...
...
ENDMETHOD|ENDFUNCTION|ENDFORM.

Cause:

The undocumented addition NON-LOCAL changes the attributes of a class or the local data objects of a procedure
into global data objects of the main program . However, global data objects can only be defined in the main program, by their very nature. In particular, class pools cannot contain global data objects; NON-LOCAL allows developers to get round this rule.
