  Key Concepts: 
  Entity view is a type of database view in SAP that combines data from multiple tables into one view. It is used to simplify the process of accessing data from multiple tables in a single query. Entity views are created in the ABAP Dictionary and can be used in both ABAP and SQL statements. 
  
  How to use it: 
  Entity views are created in the ABAP Dictionary using the Create View command. The view is then populated with fields from the underlying tables. Once the view is created, it can be used in both ABAP and SQL statements to access data from multiple tables in a single query. 
  
  Tips & Tricks: 
  When creating an entity view, it is important to ensure that all of the fields used in the view are compatible with each other. This means that all of the fields must have the same data type and length. Additionally, it is important to ensure that all of the fields used in the view are indexed for optimal performance.
