• Key Concepts: 
  Behavior Definition Language (BDL) is a programming language used in the SAP ABAP Runtime Environment (BC-ABA) to define the behavior of an application. It is used to define the logic of an application, such as how it should respond to user input, how it should interact with other applications, and how it should process data. BDL is a high-level language that is easy to learn and use.
  
  How to use it: 
  BDL can be used to create applications that are tailored to specific business needs. It can be used to create custom applications, or to modify existing applications. To use BDL, developers must first create a BDL program, which is a set of instructions that define the behavior of the application. The program is then compiled into an executable file, which can be deployed on the SAP ABAP Runtime Environment.
  
  Tips & Tricks: 
  When creating a BDL program, it is important to consider the performance of the application. BDL programs can become complex and difficult to maintain if they are not designed properly. It is also important to consider the security of the application, as BDL programs can be vulnerable to malicious attacks.
