What does it do? Compares an interval in a condition> in a ABAP_CDS_V1_VIEW >. The relational expression is true if the value of lhs> is between the values of rhs1> and rhs2>. The expression has the same meaning as the following combination of two comparisons>: ... lhs >= rhs1 AND lhs < = rhs2 ...> The corresponding context-dependent rules apply to the operands> lhs>, rhs1>, and rhs2> as well as the same conditions> for the data types.
