• Key Concepts: 
  A derived data type is a data type in SAP that is based on an existing data type. It is used to define a new data type that has the same characteristics as the original, but with additional restrictions or modifications. For example, a derived data type could be used to limit the length of a character field or to add a check table to a field. 
  
  How to use it: 
  Derived data types are used in the ABAP Runtime Environment (BC-ABA) of SAP. To create a derived data type, you must first define the original data type and then create the derived data type based on it. The derived data type can then be used in programs and screens to restrict or modify the characteristics of the original data type. 
  
  Tips & Tricks: 
  When creating a derived data type, it is important to consider how it will be used in programs and screens. This will help ensure that the restrictions or modifications you make are appropriate for the intended purpose. Additionally, it is important to remember that any changes made to the original data type will also be applied to any derived data types based on it.
