  Key Concepts: 
  Projection view is a type of database view in SAP that is used to project data from one or more tables into a single view. It is used to join multiple tables together and create a single view of the data. The projection view can be used to join tables with different structures, such as different field lengths or data types. 
  
  How to use it: 
  Projection views are created in the ABAP Dictionary using the transaction code SE11. The view can be created by selecting the “Projection View” option from the drop-down menu. Once the view is created, it can be used in other transactions, such as SE16N, to access the data from multiple tables in a single view. 
  
  Tips & Tricks: 
  When creating a projection view, it is important to ensure that all of the fields in the view have compatible data types and lengths. This will ensure that the data can be joined correctly and that no errors occur when accessing the data.
