ABAP contains the following operators:

  • Operators that perform special operations in operand positions:
  • Declaration operators
    The declaration operators DATA and FIELD-SYMBOL declare variables or field symbols in operand positions.
  • Constructor operators
    The constructor operators NEW, VALUE, CONV, CORRESPONDING, CAST, REF, EXACT, REDUCE, FILTER, COND, and SWITCH construct values for data objects of specific data types in constructor expressions.
  • Operators that join multiple operands in a single expression:
  • Assignment operators
    The assignment operator = joins the source field and target field of an assignment. In the case of assignments, the special casting operator ?= performs a down cast. The operator = also joins actual parameters with formal parameters, for example in procedure calls or when working with data clusters.
  • Arithmetic operators
    The arithmetic operators +, -, *, /, DIV, MOD, and ** join two or more numeric operands with an arithmetic expression. In addition, the characters + and - act as plus/minus signs in arithmetic expressions.
  • Bit operators
    The bit operators BIT-AND, BIT-OR, and BIT-XOR join two or more byte-like operands with a bit expression. The bit operator BIT-NOT negates a byte-like operand.
  • String operators
    The string operator && chains two character-like operands to a string expression.
  • Relational operators
    Relational operators occur in relational expressions, which themselves are components of logical expressions. The relational operators =, <>, <, >, <=,>=, BETWEEN, and so on join two or more operands of any data type as a comparison expression. There are additional relational operators for specific data types. The predicate operator IS qualifies an operand.
  • Boolean operators
    The Boolean operators AND, OR, and EQUIV join the results of individual logical expressions with a logical expression. The result of a logical expression is either true or false. The Boolean operator NOT negates the result of a logical expression.
  • Operator that joins two operands in compilations:
  • Literal operator
    The literal operator & joins two literals or two string templates with a literal or a string template.
