- Predicate Functions

The return value of a predicate function is a truth value. A predicate function is a special formulation of a relational expression and, like any relational expression, can be a full logical expression or part of one. This means it can be specified as a condition in control statements and other statements, as an argument in Boolean functions or conditional expressions, or in combinations with Boolean operators.

• Predicate Functions for Character-Like Arguments

• Predicate Functions for Table-Like Arguments

Note

The return value of a predicate function cannot be used in all operand positions for data objects since ABAP does not recognize Boolean data objects for the truth values true or false.
