In SAP ABAP, Views are virtual tables that allow developers to access data from one or more tables using a specific logical relationship. They simplify data retrieval and enhance performance by avoiding redundant coding. Understanding and effectively creating views is essential for anyone working in ABAP, especially when dealing with complex data models or custom reporting.
This article provides a comprehensive overview of views in ABAP, their types, creation process, and practical use cases.
A View in ABAP is a read-only representation of data derived from one or more database tables. Unlike database tables, views do not store data physically; instead, they fetch data dynamically whenever accessed.
SAP supports four primary types of views:
| Type | Description |
|---|---|
| Database View | Combines data from multiple tables using an inner join. It exists in the database. |
| Projection View | Displays a subset of fields from a single table. |
| Help View | Used in search help to fetch data from multiple tables. |
| Maintenance View | Enables data maintenance through SM30 for multiple related tables. |
You can create a view using SE11 (ABAP Dictionary). Below are the steps:

Z or Y for custom developments.Views in ABAP play a crucial role in simplifying data access and improving system performance. Whether you're working on custom reports, search helps, or SM30-based maintenance screens, understanding how to design and implement views will significantly enhance your development capabilities.
Learning to use views effectively bridges the gap between database-level design and application-level logic in ABAP. As you advance, practice creating different types of views for various business scenarios to gain deeper insight.
