Incorrect Logical Operators
You cannot use the ><(><<)> , =<(><<)> und => logical operators in ABAP Objects. This also applies to logical expressions in the WHERE addition of the LOOP statement for internal tables and the WHERE cause of Open-SQL statements.

In ABAP Objects, the following statement causes an error message:

... ><(><<)> ... =<(><<)> ... => ...

Correct syntax:

... <(><<)>> ... <(><<)>= ... >= ...

Cause:

These operators for not equal to, less than or equal to, and more than or equal to. <(><<)>>, <(><<)>=, and >= perform the same function. (as do NE, LE, and GE).
