When reading a field from an associated table in a SELECT statement, what expression is used?

In a SELECT statement when reading a field from an associated table, a path expression is the correct choice because it is specifically designed to navigate between the related tables. Path expressions allow developers to access fields of associated tables using a clear and concise syntax that expresses the relationship between data elements.

This means that when dealing with complex data models where multiple tables are related, you can use a path expression to elegantly retrieve values from these connected tables without needing to write extensive join conditions or manage multiple data structures separately. It simplifies the coding process and enhances readability, making it easier to understand the relationships between tables at a glance.

Understanding this concept is essential for working efficiently with relational data in ABAP, as it leverages the relationships defined in the data model to retrieve relevant data more intuitively.
