rel_exp - Ternary Relational Operator BETWEEN


Syntax
ABAP_KEY ... operand [NOT] BETWEEN operand1 AND operand2 ...

Effect
A comparison expression with the relational operator BETWEEN checks what belongs to an interval. The relational expression checks whether the content of an operand operand is within a closed interval that is delimited by the operands operand1 and
operand2 . The ternary comparison expression is equivalent to the following join between two binary comparison expressions:
... [ NOT ] ( operand = operand1 AND operand = operand2 ) ...
All operands are general expression positions and the usual comparison rules apply.

Example
Checks whether today is a working day and assigns the result to a variable declared inline .
DATA(work_day_flag) = boolc( sy-fdayw BETWEEN 1 AND 5 ).
