Typical operands are:
- Data objects from the same ABAP program
Data objects in operand positions are changed (write positions) or evaluated (read positions). At ceratin read positions you can also specify functions and expressions instead of data objects.
- Types from the same program or the Repository
Types such as data types, classes, or interfaces are specified in declarations, typings, or when addressing components.
- Callable units from the same program or the Repository
Call units such as ABAP programs, procedures, or dynpros are called during the execution of the statement.
