• Key Concepts: 
  Annotation propagation is a feature of the ABAP Dictionary in SAP that allows developers to propagate annotations from one object to another. Annotations are labels that can be used to describe objects, such as tables, views, and structures. Annotation propagation allows developers to quickly and easily apply the same annotation to multiple objects.
  
  How to use it: 
  To use annotation propagation, developers must first create an annotation in the ABAP Dictionary. This can be done by selecting the “Annotations” tab in the ABAP Dictionary and then clicking “Create”. Once the annotation has been created, it can be applied to any object in the ABAP Dictionary by selecting the “Annotations” tab and then clicking “Propagate”. This will open a window where the developer can select which objects they want to apply the annotation to. 
  
  Tips & Tricks: 
  When using annotation propagation, it is important to remember that annotations are only applied to objects that have not already been annotated. This means that if an object already has an annotation, it will not be overwritten by the new annotation. Additionally, annotations can only be applied to objects of the same type (e.g., tables, views, structures).
