  Key Concepts: 
  Built-in ABAP types are data types that are predefined in the ABAP language. They are used to define the structure of data elements and variables in ABAP programs. The built-in ABAP types are divided into two categories: elementary and structured. Elementary types are simple data types such as numbers, characters, and dates, while structured types are more complex data types such as tables and structures. 
  
  How to use it: 
  Built-in ABAP types can be used to define the structure of data elements and variables in ABAP programs. When defining a variable, the programmer must specify the type of the variable, which will determine how the variable is used and how it is stored in memory. For example, if a variable is defined as an integer type, then it can only store integer values. 
  
  Tips & Tricks: 
  When defining variables in an ABAP program, it is important to choose the appropriate type for the variable. Choosing an inappropriate type can lead to errors or unexpected results when running the program. It is also important to consider the size of the data type when defining variables; for example, if a variable needs to store large amounts of data, then a larger data type should be used.
