In the context of ABAP, what does 'Return values' signify?

Return values in ABAP function modules refer to the outputs generated as a result of executing the function. They are dynamic and are dependent on the processing logic within the function. When a function is executed, it may perform various operations and calculations based on the input parameters and other business logic, leading to specific outcomes that are then conveyed through the return values. This makes return values essential for determining the success or failure of the function execution and allows the caller to receive data relevant to the function's operations.

Return values serving as outputs allow developers to handle the results accordingly, perhaps logging success messages, displaying results to users, or managing any errors that might occur during processing. This capability for dynamic output is crucial for effective error handling and ensuring that the function behaves as intended, which is particularly relevant in complex business applications where varied outcomes can arise based on different inputs.

The other choices either present misunderstandings or inaccurate descriptions of what return values are in the context of ABAP and function modules.
