What is a key advantage of using a projection view in SAP?

The use of a projection view in SAP primarily allows for selective field retrieval. This kind of view is particularly useful because it enables users to define specific fields that they want to access from one or more underlying database tables, effectively tailoring the dataset to their specific requirements. By doing so, it simplifies data access and minimizes the amount of unnecessary data retrieved, which enhances application performance and efficiency.

Projection views are beneficial not only for optimizing queries but also for presenting only the relevant information needed by the users or applications, thus making data handling more straightforward. This focused approach directly caters to the needs of the user, allowing for improved data management in SAP environments.
