Component of an ABAP statement that, when combined with operands, forms an expression. When the statement is executed, an operation is executed for two operands joined by an operator and the result is processed further in the statement. The operators of this type are arithmetic, bit, string, Boolean, relational, and assignment operators. Other operators exist that do not join operands and which perform other operations in operand positions. Operators of this type are the dereferencing operator, declarations operators, and constructor operators. Finally, the literal operator is used to join two literals.
