Which of the following is NOT a valid data type in ABAP?

In ABAP, which is the programming language used for SAP applications, data types play a crucial role in defining how data is stored and manipulated. Among the given options, C (character data) is a valid data type, P (packed number) is also valid, and S (string) is valid as well.

The correct choice, C, refers to the data type that does not exist in the context of ABAP. The valid types typically include character (C), packed (P), and various other formats like integer (I), floating point (F), and string types, but B does not represent a recognized data type in ABAP.

Understanding the valid data types is essential for effectively programming within the SAP environment, as each type has specific uses and characteristics that dictate how data can be processed. Familiarity with these types allows developers to leverage ABAP effectively for data handling and application logic.
