• Key Concepts: 
  A signal is a type of communication used in SAP's Client/Server Technology (BC-CST). It is a message sent from one application to another, usually in response to an event or action. Signals are used to synchronize the activities of different applications and ensure that they are working together properly. 
  
  How to use it: 
  Signals are used to send messages between applications in SAP's Client/Server Technology. When an event or action occurs, a signal is sent from the source application to the target application. The target application then responds accordingly. For example, if an order is placed in an e-commerce system, a signal can be sent to the inventory system to update the stock levels. 
  
  Tips & Tricks: 
  When using signals, it is important to ensure that the source and target applications are properly synchronized. This will ensure that the signal is received and processed correctly. Additionally, it is important to consider the security implications of sending signals between applications.
