Effect
Method call in ABAP Objects. There is a difference between static method calls, where the name of the
method must be fully known in the program, and dynamic method calls, where the method ID is determined
entirely or in parts at runtime. A static method call can be executed in different forms. In one form,
the parameters are passed in a parenthetical expression, in the other without a parenthetical expression.
For the parenthetical expression, short forms are allowed. Method chainings are also an option. In dynamic
method calls, the parameters cannot be specified in parentheses and the statement CALL METHOD must be used.
When an instance method is called using a reference variable and the static type of the reference variable is a superclass of the dynamic type, the dynamic method call can be used to call all visible methods of the dynamic type. In static method calls, however, only the visible methods of the static type can be called.
System Fields
The system field see-subrc is set to 0 when a method is called. If a
non-class-based exception is raised that was handled by the assignment of a value, then see-subrc is set to this value.
