  Key Concepts: 
  A compound view is a type of view in the ABAP Runtime Environment of SAP. It is a combination of two or more database tables that are joined together to form a single view. This allows users to access data from multiple tables in one query. 
  
  How to use it: 
  Compound views can be created using the ABAP Dictionary. The user must define the tables and fields that will be used in the view, as well as the join conditions between them. Once the view is created, it can be used in queries and reports just like any other database table. 
  
  Tips & Tricks: 
  When creating a compound view, it is important to consider the performance implications of joining multiple tables together. If the query is too complex, it may take a long time to execute and cause performance issues. It is also important to consider the data that will be returned by the query and make sure that only relevant data is included in the view.
