Incorrect Plus-Bracket Notation

In ABAP Objects and as of Release 7.0, even outside of classes, no emplty plus-bracket notations are allowed.

In ABAP Objects, the following statements cause an error message:

DATA: f1() TYPE ...,
f2+ TYPE ...,
f3 LIKE f1+().

SELECT SINGLE ... FROM +(f1) INTO (f2+off(), f3+(len)).

WRITE AT +(len) f3().

Correct syntax:

DATA: f1 TYPE ...,
f2 TYPE ...,
f3 LIKE f1.

SELECT SINGLE ... FROM (f1) INTO (f2+off, f3(len)).

WRITE AT (len) f3.

Cause:

You can only use the plus symbol for arithmetical operations and offset/length addressing. In the latter, the plus symbol without a subsequent offset value is superfluous. At present, the system ignores a single plus sign directly after a field name or directly before a parenthesis. This allows you to insert the plus symbol in places in which offset/length addressing. is not available - for example, before dynamic expressions or in data declarations where only length addressing is possible. The system also ignores empty parentheses after the plus sign, offset value, or field name.
