What are advantages of using a field symbol for internal table row access?

Using a field symbol for internal table row access provides a significant performance advantage, which is why the assertion about speed is correct. When you use a field symbol, you create a reference to an internal table row rather than copying the entire row into a work area. This means that the operation can be performed more quickly since it avoids the overhead associated with copying data. Accessing a field symbol allows direct manipulation of the internal table, resulting in a more efficient memory usage and faster execution time, especially when dealing with large datasets.

The ability to operate directly on the internal table without needing a separate work area streamlines processing and enhances performance. This is particularly advantageous in scenarios with iterative data processing where speed is crucial.
